## What it does

Antigen describes itself as an AI adversary for enterprise security. Its current [homepage](https://antigen.sh/) says the system maps and attacks an organization’s surface, reproduces vulnerabilities, opens fixes and retests them. Findings are shown with traces, reproduction steps and remediation context, and can flow into GitHub, Linear or the Antigen platform.

Teams connect services, resources and identities in an Asset Map; an offensive agent attacks approved targets; a finding keeps its evidence and work history; then a human task is created when an agent needs access, review or a decision. The docs also say fixes are prepared for review and deployed by the customer, after which the agent tests whether the issue was resolved.
