Antigen is an AI-powered offensive security platform for the enterprise. It autonomously maps, exploits, and secures an organization's attack surface through nightly automated offensive testing and monthly human red team assessments, delivering findings with full traces, reproduction steps, and remediation integrated directly into GitHub, Linear, or the Antigen Platform. The company serves clients in financial services, healthcare, retail, and government, and is backed by Y Combinator (F25), Lightspeed, DST Global, and Susa Ventures.
