Astra Pentest

Astra Pentest provides you with a centralized platform to manage your entire security testing lifecycle. You can run automated vulnerability scans that check for over 8,000 security loopholes, including OWASP Top 10 and SANS 25 threats. The platform integrates manual pentesting by security experts to uncover complex logic flaws that automated tools often miss, giving you a complete picture of your security posture.

You can manage the entire remediation process directly within the dashboard, where you can collaborate with security researchers to fix vulnerabilities. The software provides detailed reproduction steps and video proof for every finding, helping your developers resolve issues faster. It also helps you maintain continuous compliance with standards like SOC2, HIPAA, and ISO 27001 through scheduled scans and automated reporting.
