We are impressed by Astra's commitment to continuous rather than sporadic testing.

Astra not only uncovers vulnerabilities proactively but has helped us move from DevOps to DevSecOps

Vinish Vijayan
IT Manager, Muthooth Finance

Their website was user-friendly & their continuous vulnerability scans were a pivotal factor in our choice to partner with them.

Larry Crawley
CTO, Strategic Audit Solutions, Inc.

The combination of pentesting for SOC 2 & automated scanning that integrates into our CI pipelines is a game-changer.

Jack Collins
Head of Product Engineering, Naro

I like the autonomy of running and re-running tests after fixes. Astra ensures we never deploy vulnerabilities to production.

Arthur De Moulins
Web Architect, Vkard

We are impressed with Astra's dashboard and its amazing ‘automated and scheduled‘ scanning capabilities. Integrating these scans into our CI/CD pipeline was a breeze and saved us a lot of time.

How much does a penetration test cost?

Industry pricing ranges from $5,000 to $50,000+ per engagement. Astra's PTaaS model starts at $1,999/year for automated scanning, with expert manual pentesting at $5,999/year — typically 60-80% less than traditional engagement-based pricing.

How long does a penetration test take?

Automated scans complete within 24-72 hours. Manual pentesting takes 5-10 business days depending on scope. You receive findings as they're discovered, not just at the end.

Does SOC 2 require penetration testing?

While SOC 2 doesn't explicitly mandate pentesting, most auditors expect it as evidence of security control effectiveness. Astra's reports are formatted for SOC 2 auditor review with mapped controls and documented evidence.

What makes Astra different from other pentesting companies?

Three things: (1) Automated scanning + manual testing on one platform. (2) Zero false positives — every finding verified by a security engineer. (3) A publicly verifiable security certificate after remediation, not just a PDF report.

Can I integrate Astra into my CI/CD pipeline?

Yes. Native integrations with Jira, GitHub, GitLab, Slack, and Jenkins. Scans trigger on every deploy with vulnerability alerts sent directly to your team's workflow.
