Detailed Review of Antigen - Other AI Software (2026)

What is Antigen?

Antigen continuously maps and exploits your attack surface, fixes confirmed vulnerabilities, and verifies every remediation with AI-powered pentesting. Antigen is the AI adversary that maps, exploits, and secures your entire attack surface. Antigen probes your live attack surface the way an attacker would, chaining weaknesses traditional security scanners report in isolation into paths that actually reach sensitive data. Antigen writes the fix, opens a pull request with the patch, and updates your project management tool. But nothing merges on its own: the PR routes to your engineers, who review and approve before anything reaches production.
