About Antigen
Antigen is an AI adversary for the enterprise. It maps, exploits, and secures your attack surface through nightly automated offensive testing and monthly human red team assessments. Every finding is delivered with traces, reproduction steps, and remediation directly in GitHub, Linear, or the Antigen Platform. We work with companies in financial services, healthcare, retail, and government where security is trust. We're backed by Lightspeed, DST Global, and Susa Ventures.
