13 Best Astra Security Alternatives for Developers in 2026

Astra Security is a PTaaS platform that pairs a DAST vulnerability scanner with human, certified pentesters on one dashboard, sold per target per year. Teams look past it for three concrete reasons: it ships no SAST and never scans source code to find bugs, it has no free tier beyond a $7 one-week scanner trial, and its human pentest is gated behind a $5,999-per-year annual subscription and a sales call rather than self-serve checkout.

Our pick is CodeAnt AI, which closes the code-scanning gap Astra leaves open while still delivering agentic pen testing. CodeAnt is our product, so we say so plainly, and every claim below is tied to an official pricing page or a real G2, Capterra, Gartner, or PeerSpot review.

TL;DR, the 13 best Astra Security alternatives in 2026:

• CodeAnt AI reviews every pull request with inline SAST and runs agentic pen testing you pay for only when it returns a working exploit, the source-code half Astra never touches.

• Aikido Security adds the SAST, SCA, secrets, and cloud scanning Astra skips, behind one flat platform fee with a free tier.

• SonarQube brings 7,000-plus static rules across 40-plus languages, the deep code analysis Astra has none of.

• Codacy puts per-seat SAST, security, and AI IDE guardrails on one plan, priced by developer rather than by target.

• DeepSource pairs deterministic static analysis with AI review and Autofix, free for open source.

• StackHawk does developer-first DAST across unlimited apps for a per-seat price, rather than one target at a time.

• Intruder runs continuous vulnerability and attack-surface management with a genuine free tier Astra lacks.

• Cobalt delivers deeper on-demand human pentests from a vetted community, scoped in credits.

• Synack fields a FedRAMP-grade vetted red team plus an AI agent for enterprise continuous validation.

• NodeZero runs autonomous internal network, cloud, and Active Directory pentests Astra reaches only at Enterprise.

• Pentera validates the whole estate with agentless automated security testing.

• XBOW is an autonomous AI pentester priced per engagement that topped the HackerOne US leaderboard.

• Hadrian discovers unknown external assets from zero scope, then pentests them 24/7.

What Is Astra Security?

Astra Security is a Penetration Testing as a Service platform whose homepage promises that “security conscious companies trust Astra for continuous pentests.” The pitch is that traditional point-in-time pentests cannot keep up with continuous deployment, so Astra blends an always-on scanner with certified human testers on a shared dashboard.

The product spans five surfaces on one platform: PTaaS with manual and automated VAPT, a DAST scanner with more than 10,000 test cases, an API security platform, a multi-cloud vulnerability scanner across AWS, Azure, and GCP, and a newer Autonomous Pentest layer still gated behind a waitlist. Human pentesters carry OSCP, CEH, and CREST credentials, and reports come recognized by auditors for SOC 2, ISO 27001, PCI-DSS, and HIPAA.

The one thing Astra does not do is static analysis. Its own product nav lists exactly five products, and none of them scans a repository to find bugs. Astra can read your codebase through an MCP integration, but only to write a fix for a vulnerability its DAST or pentest engines already found at runtime, which is remediation delivery rather than source-code review.

How much does Astra Security cost?

Astra publishes fully public pricing on getastra.com/pricing, split into separately priced product lines and billed per target, where one SaaS app plus its APIs and underlying cloud counts as a single target. The DAST Scanner runs $69 per month (Scanner Lite, 1 target, 3 scans a month) up to $499 per month (Scanner Agency, a 5-target pool), and annual billing carries a 15% discount.

Pentests are sold annually only, with no per-engagement option. Pentest Auto is $1,999 per year for an autonomous test with one human re-scan, Pentest Expert is $5,999 per year for a manual test by certified experts with two re-scans, and Enterprise is custom. A manual pentest takes 10 to 15 working days to complete.

Teams look elsewhere where the model pinches. There is no free tier, only a $7 one-week trial that covers the DAST scanner and not the pentest, the Pentest Expert card routes to “Schedule a call” rather than self-serve checkout, and the whole platform leaves source-code scanning to another tool. The alternatives below each answer a different one of those gaps.

The 13 Best Astra Security Alternatives at a Glance

Here is the field, ranked with CodeAnt AI first for developer fit, then grouped from code-security platforms through DAST, vulnerability management, pentest-as-a-service, and autonomous testing.

The 13 Best Astra Security Alternatives in 2026

Every tool below is weighed against what Astra actually does and does not do: whether it scans source code, how its pentest depth compares, whether it charges per target or per seat, and whether it offers a free way in. Each section carries Astra’s own pricing next to the tool’s, a real screenshot, and at least one third-party review so no claim rests on marketing copy.

1. CodeAnt AI

CodeAnt AI is the best Astra Security alternative for developers in 2026 because it fills the exact gap Astra leaves. Astra never scans a repository to find bugs, while CodeAnt reviews every pull request with inline SAST and adds agentic pen testing you pay for only when it hands back a working exploit.

On pentest depth, CodeAnt’s own production runs have surfaced an unauthenticated API exposing 3.2M patient records at a US healthcare provider, a broken-object-level-authorization chain reaching 6M passenger records at an airline, and 500K-plus client files at a UK law firm. Jeson Patel, CTO at Series B startup 11x, said CodeAnt “went deeper than any penetration test we’ve ever commissioned,” calling it “the most thorough offensive security platform we’ve used.”

Features of CodeAnt AI

• The source-code layer Astra never ships. SAST, SCA, secret detection, and IaC checks run inline on every pull request, catching the injection or hardcoded-credential bug in the code itself, where Astra only ever tests the deployed app.

• AI review on the PR before anything deploys. Inline comments flag logic errors and edge cases with one-click fixes across 30-plus languages, upstream of the runtime stage Astra’s scanner works at.

• Pentest billed by the exploit, not by the year. Agents chain attack paths and return a 48-hour report, charging only for exploitable High and Critical findings, against Astra’s flat $1,999-to-$5,999 annual per-target subscription.

• Code-to-cloud coverage in one login. CSPM, container and VM scanning, and DAST sit beside the code and pentest tooling, so you get Astra’s runtime reach plus the source coverage Astra has none of.

• The Bitbucket and Azure repos Astra will not connect to. Native GitHub, GitLab, Bitbucket, and Azure DevOps support plus VS Code, Cursor, Windsurf, and IntelliJ, where Astra’s SCM support stops at GitHub and GitLab.

• A free way in Astra does not offer. Public repositories run the whole platform at no cost and private teams start on a 14-day trial with 100 PR reviews, rather than Astra’s paid $7 scanner week.

Pros of CodeAnt AI

• Catches the code bugs Astra’s runtime scan cannot see. An IT Services reviewer on Gartner Peer Insights called the feedback “highly accurate” for “pointing out issues with edge cases, missed logic, and even mundane things that are easy to miss like naming inconsistencies and copy/paste errors.”

• Works with the Bitbucket repos Astra leaves out. Aman B., a Director of Engineering, wrote on G2 that it is “one of the few tools which works with BitBucket” and that it “reduced considerable time to review PR.”

• Flags real security issues at the PR, not post-deploy. Ellie Powers of Elvin wrote on Product Hunt the team has “been helpful in finding important security issues,” and a Scoutflo reviewer described an “Aha moment the minute our Github PRs were summarised after installation.”

Cons of CodeAnt AI

• Onboarding takes a beat. A mid-market reviewer on G2 noted suggestions can feel “too cautious or sometimes it needs manual adjustments, also onboarding takes time,” a tuning step Astra’s fully managed pentest sidesteps.

• The odd false positive on review. Aman B. on G2 accepted “occasional False positive though is small price to pay for actual bugs.”

• A younger review pool than Astra’s. CodeAnt’s 4.8 on G2 rests on fewer entries than Astra’s 4.6 across 168 seller-level G2 reviews, so lean on the free trial rather than the star count.

CodeAnt AI vs Astra Security pricing

Best for: teams that want the source-code review and inline SAST Astra never runs, plus real pen testing they pay for only when a working exploit ships.

2. Aikido Security

Aikido Security is the most direct answer to Astra’s biggest gap. Astra scans running apps and cloud but never the code, while Aikido runs SAST, SCA, secrets, and IaC on the repository itself and folds in its own AI pentesting and DAST from one dashboard.

For a team already on Astra for pentests, Aikido is the way to add shift-left scanning without buying a second point tool, and it opens with a free Developer plan Astra has no equivalent for.

Features of Aikido Security

• The repository scanning Astra skips. SAST across 20-plus languages, SCA with reachability triage, secrets with git-history scanning, and IaC checks all run on the PR, reading the code Astra’s DAST and pentest never open.

• Cloud and runtime beside the code. CSPM, container and Kubernetes scanning, VM scanning, and the Zen in-app firewall reach from repo to production, overlapping Astra’s cloud scanner while adding the source layer it lacks.

• Its own AI pentest and DAST. Aikido /Attack maps exploitable routes into attack graphs and produces SOC 2 and ISO pentest-style reports, so a team consolidates rather than running Astra next to a separate SAST tool.

• Filtering tuned to keep PRs moving. Reachability, exploitability, and exposure triage with a claimed 90% SAST false-positive cut on its Opengrep ruleset, aimed at the merge gate Astra has no presence at.

Pros of Aikido Security

• Consolidates the point tools Astra would sit beside. Christian Schmidt, VP Security and IT at Go Autonomous, said on Aikido’s site “there wasn’t noise reduction in Snyk,” and “with Aikido, the triaging is just… done.”

• Rolls out to a dev team without a sales call. Marc Lehr of GEA wrote on Aikido’s enterprise page “in just 45 minutes, we onboarded 150+ developers with Aikido,” a self-serve motion Astra’s sales-gated Pentest Expert does not match.

• Quiet enough to live in the workflow. Cornelius at n8n wrote “with 92% noise reduction, we got used to ‘the quiet’ quickly,” calling it “a massive productivity and sanity boost.”

Cons of Aikido Security

• Pentest depth leans automated. Aikido’s pentest is AI-driven and its Rightsized human tests are scoped by its own analysis, rather than Astra’s 10-to-15-day manual engagement by CREST-certified experts with a publicly verifiable certificate.

• Tier caps replace Astra’s per-target meter. Each plan bundles 10 users plus hard limits on repos, containers, domains, and cloud accounts, so growth forces a tier jump instead of adding a target.

• A thin independent review base. Aikido’s cited praise comes from its own customer pages rather than a G2 or Capterra corpus like Astra’s, so trial the pentest side before dropping Astra for it.

Aikido Security vs Astra Security pricing

Best for: Astra users who want to add SAST, SCA, and cloud scanning of the code itself, on a flat platform fee with a free tier to start.

3. SonarQube

SonarQube is the deepest static-analysis engine in the field, and it addresses the one thing Astra has zero of. Astra tests running apps and delivers pentests, while SonarQube reads the source and enforces quality and security gates before code ever merges.

It is a complement to Astra rather than a swap, since it does no dynamic testing and no pentesting of its own.

Features of SonarQube

• The static depth Astra has none of. More than 7,000 issue types across 40-plus languages under the Clean Code taxonomy, at a published 3.2% false-positive rate, reading source Astra scans nowhere.

• Gates that stop bad code before it merges. Clean as You Code focuses quality gates on new code so old debt never stalls a PR, catching bugs at the pre-merge point Astra’s runtime scan sits far downstream of.

• SAST with taint tracking on the source. Built-in SAST and taint analysis, with SCA and advanced SAST on the paid Advanced Security add-on, covering injection classes Astra can only observe once the app runs.

• PR decoration across the SCMs Astra omits. GitHub, GitLab, Bitbucket, and Azure DevOps decoration plus a free IDE plugin and an MCP server, reaching the Bitbucket and Azure repos Astra’s GitHub-and-GitLab-only support does not.

Pros of SonarQube

• Measurably fewer production bugs. Vitthal Gole, a DevOps engineer at AIQOD, wrote on PeerSpot that after adding SonarQube to CI/CD “we reduced production bugs by 30 to 40 percent and improved code coverage from 65 to 85 percent.”

• Enforces coverage right on the PR. Michal P. noted on Capterra “SonarQube is good at enforcing minimum code coverage on PRs,” and Swarnima G. praised a dashboard giving “a clear overview of code health,” gates Astra never applies to code.

• A genuinely free start where Astra charges. A no-cost open-source Community Build covers 21 languages self-hosted, against Astra’s paid $7 scanner week and no free tier.

Cons of SonarQube

• No DAST or pentest at all. SonarQube does no dynamic testing or penetration testing, so it complements rather than replaces the runtime scan and human pentest that are Astra’s whole product.

• False positives still need a human. Vitthal Gole noted “some findings require manual verification,” and Philip J. on Capterra wrote plainly “False positives are annoying.”

• Line-of-code pricing climbs. A PeerSpot reviewer flagged a jump to “$15,000 per one million lines,” a steeper curve than Astra’s flat per-target fee, and a banking reviewer warned hard gates “may block delivery/deployment.”

SonarQube vs Astra Security pricing

Best for: teams that want the deepest, most language-complete SAST and code-quality gates to sit alongside Astra’s runtime pentesting.

4. Codacy

Codacy brings the code layer to teams shipping AI-generated code, priced by developer rather than by target. Astra scans the deployed app, while Codacy unifies code quality, SAST, SCA, secrets, IaC, container scanning, and DAST behind one per-seat plan.

Its sharpest angle against Astra is AI Guardrails, an IDE and agent layer that enforces your standards on every prompt before code reaches a PR, upstream of anything Astra tests.

Features of Codacy

• Code scanning billed per developer, not per target. Quality checks, SAST, SCA, secrets, IaC, and container scanning run under one shared standard on a per-seat fee, reading the source Astra never touches.

• Guardrails on AI code before it reaches a PR. An MCP-driven extension enforces rules on every prompt across VS Code, JetBrains, Cursor, and Windsurf, upstream of the deployed app Astra scans.

• SAST across 12,000-plus rules plus ZAP DAST. Daily CVE re-scans, secrets, and OWASP ZAP DAST on the Business tier give automated dynamic testing alongside the static analysis Astra omits.

• A live inventory of AI in the codebase. Automatic tracking of every model, MCP server, and coding tool mapped to EU AI Act and ISO 42001 evidence, a code-governance surface outside Astra’s pentest remit.

Pros of Codacy

• Live on a repo in minutes. Amir B., a retail CTO, wrote on Capterra Codacy “just takes a few mins to set up, and you start getting reports on a wide variety of languages. Leaves comments on PR’s for you,” the PR-comment loop Astra has no equivalent for.

• Takes style arguments off senior reviewers. Graeme K., an IT Services CTO, noted it “frees up Senior Resources to add value instead of arguing about casing and low level standards.”

• A workable Code Climate swap with on-prem. Chris M., a staff engineer in network security, called it “a great alternative to Code Climate” with the on-prem option his team needed, deployment flexibility Astra reserves for Enterprise.

Cons of Codacy

• No certified human pentest. Codacy’s DAST is automated ZAP scanning, so it lacks the CREST-certified manual pentest and auditor certificate that are Astra’s core deliverable.

• On-prem costs more and support drags. Chris M. noted the on-prem option is “2.5x more expensive than the hosted license per seat” and that support “is very slow to respond.”

• Cloud Git only. Codacy Cloud connects to cloud-hosted GitHub, GitLab, and Bitbucket while Azure Repos waits on a list, a gap for the Azure teams Astra’s scanner would still serve.

Codacy vs Astra Security pricing

Best for: teams that want per-seat code quality and AppSec with IDE guardrails for AI-generated code, alongside Astra’s runtime pentesting.

5. DeepSource

DeepSource combines deterministic static analysis with AI review, which is precisely the pre-merge layer Astra does not have. Astra finds issues in the running app, while DeepSource catches them in the code with rule-backed findings rather than an LLM guess alone.

Its wedge is accuracy plus self-serve simplicity, with a published per-seat price and a free open-source tier where Astra offers only a paid week.

Features of DeepSource

• Rule-backed static analysis Astra does not run. More than 5,000 deterministic rules across 30-plus languages paired with AI Review, so findings rest on rules rather than a model alone, reading code Astra scans nowhere.

• Autofix you preview before the merge. Pre-generated patches shown as a diff before you accept, aimed at cleaning AI-written code at the PR stage Astra never reaches.

• SCA ranked by real reachability. Dependency scanning with a Dynamic Risk score folding CVSS, EPSS, and reachability to cut noise up to 60%, the dependency layer Astra’s runtime scan does not inspect.

• Secrets and coverage in the same pre-deploy pass. A hybrid secrets engine validated against 165-plus providers, IaC hardening, and code-coverage gates, all before the deploy Astra tests after.

Pros of DeepSource

• Points to the exact offending line. Adrian V., an embedded developer, wrote on Capterra “Code’s analysis is very complete and specific, pointing to the exact line with the issue. And It also can resolve them automatically,” source-level precision Astra reports only at runtime.

• Links to GitHub with no friction. Adrian V. valued that “the feature of automatic linkage with the GitHub repositories is very useful and time saving,” and Reunaldo P. praised “how simple the setup process was.”

• Publishes its accuracy numbers. DeepSource reports an F1 score of 84.51% on a 165-CVE benchmark ahead of several AI reviewers it names, transparency Astra’s scanner does not put on the table.

Cons of DeepSource

• No DAST or pentest. DeepSource states on its own site it does not cover DAST or container scanning, so it stays a pre-merge tool next to Astra rather than a substitute for the pentest.

• Occasional false positives. Marek T., a financial-services CEO, noted “occasional false positives… it flagged certain code segments as problematic when, in reality, they were not.”

• Can overwhelm on volume. Sanket T., a full-stack developer, wrote it “could generate a lot of input, which some engineers might find overwhelming,” a triage load Astra’s expert-vetted scans aim to spare you.

DeepSource vs Astra Security pricing

Best for: teams that want accurate, low-noise static analysis and Autofix with transparent per-seat pricing, to run before Astra ever sees the deployed app.

6. StackHawk

StackHawk plays in Astra’s own DAST lane but comes at it per seat and inside the coding agent. Astra prices its scanner per target with unlimited scans, while StackHawk charges per user for unlimited apps and teaches the agent to fix and re-verify before a PR opens.

For a team with many apps and a per-seat budget, that math flips Astra’s per-target model on its head.

Features of StackHawk

• DAST priced per seat, not per target. HawkScan tests running apps over HTTP with reproducible results, spun up and down per scan in CI, across unlimited apps for one per-user fee against Astra’s per-target scanner.

• API protocol reach past Astra’s scanner. Native testing for REST, GraphQL, gRPC, SOAP, and MCP server tools with OpenAPI specs auto-generated from source, wider than Astra’s REST, SOAP, and GraphQL coverage.

• Find, fix, and re-verify inside the agent. One install teaches Claude Code, Cursor, Codex, Antigravity, and Copilot to scan, remediate with source context, and rescan, a developer loop Astra’s dashboard-and-Slack flow does not run.

• Data-flow mapping on the Scale tier. Attack-surface discovery maps every app and API from source and flags where PII, PCI, or HIPAA data concentrates, context Astra’s per-target scan does not build.

Pros of StackHawk

• Drops cleanly into CI/CD. A reviewer in computer software praised the “scanning capabilities and easy integration into CI/CD pipelines” on AWS Marketplace, and David M. called onboarding “one of the best I’ve seen.”

• Proves risk in the running app. A security-operations manager on PeerSpot valued the “ability to report any issues that may exist with code running live,” crediting it toward PCI certification, the runtime evidence Astra’s DAST also gives.

• A deeper rating pool than Astra’s. StackHawk holds 4.6 on G2 across 68 reviews, against Astra’s 12 Capterra entries, confirmed through G2 and AWS Marketplace syndication.

Cons of StackHawk

• No human pentest or certificate. StackHawk is DAST only, so it lacks the certified manual pentesters and the SOC 2 and ISO certificate that make Astra an audit-close tool.

• Authenticated scans can frustrate. An AWS Marketplace reviewer noted “authenticated scans can be frustrating,” and a DevOps engineer said pipeline-dependency setup “needs refinement,” the auth setup Astra handles for you on a managed pentest.

• Priced above some budgets. A security-operations manager on PeerSpot wished “the product was a little less expensive.”

StackHawk vs Astra Security pricing

Best for: developer teams with many apps that want per-seat DAST built into the coding agent, rather than paying Astra one target at a time.

7. Intruder

Intruder starts from the internet-facing estate rather than a single app target, and it hands lean teams a genuine free tier. Astra tests defined app and cloud targets, while Intruder continuously discovers and monitors the whole external attack surface for infrastructure risk.

Where Astra bills per target with no free way in, Intruder offers a free-forever plan and self-serve tiers built for teams without a dedicated AppSec function.

Features of Intruder

• Continuous scanning of the estate Astra does not map. Intruder runs OpenVAS, Nuclei, Tenable, and OWASP ZAP under one dashboard with Emerging Threat Scans within hours of a disclosure, watching infrastructure Astra’s app-and-cloud targets leave out.

• Attack-surface discovery Astra makes you define. Continuous discovery of subdomains, exposed services, and shadow IT, with CloudBot auto-scanning new AWS, GCP, Azure, and Cloudflare assets, rather than a target you name up front.

• An AI pentest you buy per test. A white-box web-app pentest that connects GitHub or GitLab and returns an audit-ready report from $3,500 per test, a per-engagement option beside Astra’s annual pentest subscription.

• An analyst built for teams without one. GregAI prioritizes and validates findings and writes plain-language remediation, plus an MCP server, aimed at the lean teams Astra’s managed pentest also courts.

Pros of Intruder

• Surfaces what actually matters. Nic H., an operations director, wrote on G2 that “rather than overwhelming us with low-value noise, it highlights vulnerabilities that genuinely matter and explains why they are important.”

• Fast to stand up and always watching. An enterprise reviewer called it “our number one, 100% vulnerability assessment tool, replacing both Nessus open source and Tenable,” adding “the initial setup was super easy.”

• A high-volume rating Astra cannot match yet. Intruder holds 4.8 on G2 across 207 reviews with a 2026 Best Software Award, far deeper than Astra’s small but genuine corpus.

Cons of Intruder

• No source code and a lighter pentest. Outside the AI add-on Intruder never reads a repo, and it has no certified manual pentest team like Astra’s CREST-approved testers.

• Uneven cloud coverage. An enterprise reviewer noted “the Azure integration for Intruder is definitely still a little bit immature,” where Astra’s cloud scanner spans AWS, Azure, and GCP.

• Per-target licensing stacks up. Community discussion points to shallower web-app depth than dedicated DAST and licensing that grows with targets, the same per-target math Astra runs.

Intruder vs Astra Security pricing

Best for: lean security and IT teams that need continuous exposure management of the external estate, with a free tier Astra does not offer.

8. Cobalt

Cobalt pioneered pentest as a service, and its human depth runs past what Astra bundles. Astra sells a fixed annual pentest per target, while Cobalt scopes engagements in credits across a vetted community and can launch a real test in as little as 24 hours.

For teams whose priority is deep, flexible human testing rather than a bundled scanner subscription, Cobalt is the stronger pentest engine.

Features of Cobalt

• Human pentests scoped in credits, not a fixed annual bundle. Web, mobile, API, network, cloud, and AI/LLM tests scoped in a four-step wizard over roughly 14 days, launchable in 24 hours against Astra’s 10-to-15-day managed timeline.

• AI recon feeding human testers. Autonomous agents run reconnaissance while people chase chained exploits and business-logic flaws, the manual depth Astra reserves for its $5,999 Pentest Expert tier.

• Retesting that stays open for months. Free retesting of individual findings for 6 to 12 months with a 7-day retest SLA, wider than the one or two bundled re-scans Astra allows.

• Secure code review done by people. A hybrid human-plus-SAST review, the nearest thing here to reading source, which Astra does not do at all.

Pros of Cobalt

• Findings engineers can act on. Arpit G., a senior staff engineer, wrote on G2 Cobalt delivers “actionable findings that are easy for engineers to understand and fix,” making security “feel collaborative rather than audit-driven.”

• Onboarding that goes smoothly. Osher L., a mid-market reviewer in SaaS healthcare, said “Cobalt impressed me with their team’s responsibility and the smooth onboarding process.”

• Testers that hold up over years. A five-year customer noted the assigned pentesters “have been pretty solid for the discovery of findings and responsive,” with “reasonable” pricing, human continuity Astra’s autonomous tier does not offer.

Cons of Cobalt

• No self-serve scanner tier. Cobalt sells human pentests, so there is no always-on DAST subscription like Astra’s $199-a-month unlimited scanning.

• Credit minimums hurt small scopes. Michał M., a security specialist, wrote on G2 he dislikes “that there is a minimum of five credits” for tests needing far less, a floor Astra’s per-target price avoids.

• Reporting could be cleaner. Osher L. said “the reporting and the interface of the reports could be better.”

Cobalt vs Astra Security pricing

Best for: teams that want deeper, more flexible human pentests from a vetted community than Astra’s fixed annual bundle, and do not need a self-serve scanner.

9. Synack

Synack is the enterprise, federal-grade end of PTaaS, well above Astra’s mid-market price point. Astra fields OSCP and CREST-certified testers at $5,999 a year, while Synack pairs the Sara AI agent with a red team that accepts under 10% of applicants and runs government background checks.

It is a security-leadership purchase rather than a self-serve one, and it earns its place for teams that need FedRAMP Moderate validation Astra does not carry.

Features of Synack

• A vetted red team past Astra’s tester bench. Sara’s agents widen coverage, then the Synack Red Team, which accepts under 10% of applicants, confirms what is exploitable and filters 99.98% of scanner noise.

• Continuous cadences Astra sells only at Enterprise. Point-in-time or continuous Synack14, Synack90, and Synack365 engagements across web, host, API, mobile, and cloud.

• Federal authorization Astra lacks. FedRAMP Moderate, ISO 27001, and testing at DoD impact levels 4, 5, and 6, credentials beyond Astra’s CREST and CERT-In reports.

• Full traffic control on every test. All testing routes through the LaunchPoint VPN with packet capture and a one-click pause, oversight Astra’s managed pentest does not expose.

Pros of Synack

• Researcher quality that shows in findings. A principal technology architect wrote on Gartner Peer Insights “I continue to be impressed with the quality of Synack’s findings, which speaks to the quality of their security researchers,” noting proactive developer training.

• Remediation detail developers learn from. Todd E. said on G2 “Synack explains exactly how each flaw was exploited and provides a full detailed explanation on how to remediate,” calling it “like getting secure code training for free.”

• Coverage broader than one in-house bench. Khai D., a cyber-defense manager, valued “a diverse pool of vetted researchers” giving “broader and more realistic coverage than traditional approaches alone,” breadth Astra’s own team cannot match.

Cons of Synack

• No code review and PO-only buying. Synack is offensive testing with no SAST, bought through procurement rather than the self-serve credit card Astra takes.

• The red team can be slow to start. Todd E. noted it can be “a little slow to spin up,” and setup gets “more complicated when API and/or multiple testing accounts are involved.”

• Cost on top of a platform fee. Jason L. flagged “cost pressures” and a market that “has become more commoditized,” over a subscription that dwarfs Astra’s $5,999 pentest.

Synack vs Astra Security pricing

Best for: enterprises and public-sector teams that need continuous, FedRAMP-grade validation from a vetted red team and can support a procurement-led purchase Astra is not built for.

10. NodeZero (Horizon3.ai)

NodeZero owns the internal network, cloud, and identity layers that Astra reaches only inside a custom Enterprise pentest. Astra focuses on web apps, APIs, and cloud config, while NodeZero autonomously chains credential attacks and misconfigurations into proven attack paths across the estate.

It runs unlimited pentests for a fixed annual fee, which is a different economics from Astra’s per-target-per-year model.

Features of NodeZero

• Unlimited internal-network pentests Astra gates at Enterprise. Internal, external, cloud, Kubernetes, and Active Directory tests that discover, exploit, and chain weaknesses with no agents installed.

• Proof of exploit on every finding. Each result ships with proof of exploit, impact, and a one-click verify, the same exploit-first stance Astra takes, aimed at the network Astra skips.

• Attacks that go past version checks. Credential attacks, misconfigurations, EDR validation, and AD password audits, identity-layer coverage outside Astra’s web-and-API focus.

• Findings wired into the SOC stack. Output to ServiceNow, Jira, Splunk, and Microsoft Sentinel plus a hosted MCP server, plumbing built for security operations rather than Astra’s dev-workflow Slack and Jira.

Pros of NodeZero

• Scope it once and let it run. Brent Hamlin, an infrastructure manager, wrote on PeerSpot the automated scans are “great to use” and you “set it, scope it, and let it go,” with impactful executive reporting.

• Shows how an attack path forms. Fabian Brandt, an IT security consultant, valued the “speed, scalability, and the ability to see how an attack path is actually formed,” and Hussain Z. called one-click verification “particularly effective.”

• Stands up in minutes. Rudolf Oyakhire reported “the deployment is very easy, taking under ten minutes,” and Horizon3.ai won a Gartner Peer Insights Customers’ Choice in 2025.

Cons of NodeZero

• No source code or web-app scan. NodeZero tests network, cloud, and AD with no SAST and no app scanner, so it does not touch Astra’s application and API surface.

• Cost against yield. A senior security engineer flagged “high cost for low-yield real attacks” and “frequent out-of-scope detections.”

• A learning curve. Rudolf Oyakhire noted a “learning curve for advanced features” and that “cost may challenge smaller organizations,” a heavier lift than Astra’s self-serve scanner.

NodeZero vs Astra Security pricing

Best for: security and IT teams that need to prove real, exploitable risk across the internal network and identity layers Astra reaches only at Enterprise.

11. Pentera

Pentera created the Automated Security Validation category and tests the whole estate rather than a defined app target. Astra pentests apps, APIs, and cloud, while Pentera safely validates internal, external, and cloud controls on demand with a deterministic attack engine.

Like NodeZero, it validates the environment rather than the code or the web app, so it sits beside Astra rather than replacing it.

Features of Pentera

• Estate-wide validation Astra scopes to app targets. No agents or network config, running remotely or on-prem across a distributed hybrid environment Astra’s per-target model does not address.

• Internal, external, and cloud in one engine. Pentera Core for internal networks, Surface for external attack surface, and Cloud for AWS, Azure, and Kubernetes, breadth past Astra’s web, API, and cloud scan.

• Test as often as you want, safely. A published do-no-harm policy with configurable range, scope, time, and stealth, and no cap on test frequency, against Astra’s one pentest per annual target.

• A co-pilot for the operator. Pentera Peer lets teams query findings and steer testing in plain language, an operator aid separate from Astra’s IDE fix delivery.

Pros of Pentera

• Board-ready at a glance. Vishnu Jadhav, a network engineer, wrote on PeerSpot “the dashboard is excellent. I can see everything at a glance,” and another valued that “attack path visualization gives me the ability to communicate with leadership and the board.”

• Real hours saved on manual testing. An education-sector reviewer reported “we have saved approximately 45% of the hours we used to spend on manual penetration testing,” the manual load Astra’s certified pentest still carries.

• False positives driven down. Angelo B., a sales engineer, credited its ability to “automatically exploit the vulnerabilities” with reducing false positives to zero on Capterra.

Cons of Pentera

• No code or app pentest certificate. Pentera has no SAST and no certified human app pentest with an auditor certificate, so it does not produce Astra’s compliance-ready deliverable.

• Six-figure pricing. A director wrote on PeerSpot “the product has become very expensive,” with estimates in the six figures a year against Astra’s low-thousands per target.

• Navigation and cloud depth. Vishnu Jadhav flagged navigation “which seems slower,” and a reviewer said “cloud testing capabilities need enhancement,” where Astra’s cloud scanner is a first-class product.

Pentera vs Astra Security pricing

Best for: large, regulated enterprises that need continuous, agentless validation of security controls across the whole estate, alongside Astra’s app-focused pentests.

12. XBOW

XBOW is the autonomous AI pentester that topped the HackerOne US leaderboard above human researchers, and it prices per engagement rather than per annual target. Astra sells a yearly pentest subscription, while XBOW takes a URL and returns working exploits at a price anchored to a manual pentest.

It focuses on web apps and APIs, and it publishes list prices, which is rare in this corner of the market.

Features of XBOW

• Autonomous exploitation billed per engagement. A learn, map, coordinate, attack, and prove loop runs thousands of short-lived agents in parallel and charges per test, against Astra’s annual per-target subscription.

• Working exploits, not a finding list. Independent validators confirm each result with a runnable exploit and an end-to-end trace, the same proof-first bar Astra sets, reached by AI alone.

• Whatever frontier model fits the step. XBOW routes each task to the best model and adopts new ones as they ship, with no lock-in, an AI-native design Astra layers onto human testing.

• A test you can fire from CI. A REST API and webhooks trigger a pentest on merge or pre-deploy, with continuous coverage on Enterprise, tighter to the pipeline than Astra’s request-and-wait flow.

Pros of XBOW

• Proven on real bug bounty programs. Utku Sen, a security researcher, wrote that if XBOW “managed to find valid bugs across multiple programs using ‘just their software’, that’s impressive,” adding “topping the VDP leaderboard is still not an easy thing to do.”

• A price that maps to a manual pentest. XBOW anchors its $4,000 tier to a two-week engagement and its $8,000 tier to a four-week one, a clearer per-test comparison than Astra’s yearly target fee.

• Chains bugs into attack paths. Moderna’s Deputy CISO praised its ability to chain bugs into attack chains, “something no other product is doing well in the web space.”

Cons of XBOW

• No human validation or certificate. XBOW is autonomous AI without Astra’s certified-human layer or the CREST and PCI-ASV pentest certificate auditors accept.

• Doubts on depth. Amélie Koran noted its HackerOne badges are “some of the more basic things you can find with automation,” and HackerOne’s co-founder observed AI still struggles with business-logic flaws.

• Not truly self-serve. Every CTA routes to a contact form and the CEO admits you must “give it a URL to start with, possibly… some additional information like credentials,” less turnkey than Astra’s checkout.

XBOW vs Astra Security pricing

Best for: teams that want fast, autonomous, exploit-proven web and API pentests priced per engagement, rather than Astra’s annual per-target subscription.

13. Hadrian

Hadrian starts where Astra requires you to already know your targets, discovering unknown external assets from zero scope. Astra scans the app and cloud you define, while Hadrian maps the full external attack surface the way an attacker would, then validates what is genuinely exploitable.

Its two products, Atlas for continuous exposure management and Nova for on-demand pentests, aim at SOC teams and CISOs rather than developers.

Features of Hadrian

• Zero-scope discovery where Astra needs a named target. Atlas maps the external attack surface automatically with hourly passive scans and event-driven testing on any change, finding assets you never listed.

• Validated findings, not raw alerts. An AI Orchestrator proves each risk with a step-by-step proof of concept and claims 99% noise elimination, the exploit-validation stance Astra applies only to defined targets.

• On-demand pentests billed per URL. Nova runs offensive tests against web apps, APIs, and cloud and returns validated findings in 24 to 48 hours, a per-test option beside Astra’s annual pentest subscription.

• Leak monitoring past the app. Infostealer and compromised-credential detection plus an M&A assessment add-on, exposure intelligence outside Astra’s scanner remit.

Pros of Hadrian

• Replaces the wait for a quarterly pentest. A mid-market reviewer wrote on G2 “Hadrian provides real-time visibility of risks that we would have to wait until a penetration test to discover,” and that “it was simple to set up and has become a daily part of our workflows.”

• Reports you can trust. An enterprise reviewer noted “prior solutions generated a lot of false-positives,” while “when Hadrian reports a vulnerability you know it is real,” the low-noise bar Astra also chases.

• Value inside minutes. An enterprise reviewer said “the system is live and working within minutes and provides insights on external attack surface in a intuitive and simple dashboard.”

Cons of Hadrian

• External only, no code or certificate. Hadrian scopes to the external attack surface with no SAST and no certified-human pentest certificate like Astra’s.

• Reporting and workflow gaps. Reviewers on G2 flagged “missing reporting or exporting functionalities” and features that “are not always fully completed.”

• A thin review base. Hadrian has only four G2 reviews against Astra’s larger footprint, and one enterprise reviewer noted “the pricing is a bit high.”

Hadrian vs Astra Security pricing

Best for: SOC teams and CISOs that need continuous discovery and testing of unknown external assets, rather than Astra’s testing of targets you already know.

Where This Leaves You

Astra Security is a capable PTaaS and DAST platform, and for teams that want a continuous scanner plus a human pentest on one dashboard it does the job. The reasons to look elsewhere are specific, from the absence of any source-code scanning to the lack of a free tier and a human pentest gated behind an annual per-target subscription and a sales call.

CodeAnt AI closes the biggest of those gaps by reviewing every pull request with inline SAST while still running agentic pen testing you pay for only when it returns a working exploit. Start with the free open-source plan or the trial, connect a repo, and let the first PR review and pentest scan show the difference.
