Problem
Organizations often lack continuous visibility into their production attack surface, relying on periodic security assessments that can miss newly introduced vulnerabilities and misconfigurations across cloud, infrastructure, and application layers.
Solution
Antigen provides an automated offensive security platform that runs AI-driven penetration testing agents against production environments every night, complemented by monthly human red‑team validations. The system maps the full attack surface, executes realistic exploit attempts, and generates detailed findings—including trace data, reproduction steps, and remediation guidance—delivered directly into developers' existing tools such as GitHub, Linear, or Antigen’s dashboard. By integrating continuous testing with actionable evidence, Antigen enables security and engineering teams to proactively address weaknesses before attackers can exploit them.
Target Audience
Primary customers are security and engineering teams at mid‑size to large enterprises that operate complex production environments across multiple cloud and application platforms and need continuous, actionable offensive security insights.
Features
- Nightly AI penetration testing agents that autonomously discover and exploit vulnerabilities across cloud, infrastructure, and application components
- Monthly expert red‑team assessments to validate and prioritize AI‑generated findings
- Automated delivery of detailed remediation evidence (traces, reproduction steps) into GitHub, Linear, or the Antigen platform
- Live visual mapping of the entire attack surface, showing services, endpoints, dependencies, and reachable paths
- Integrated SAST GitHub Action that runs static analysis on every pull request for shift‑left vulnerability detection
- Support for major cloud providers (AWS, GCP), container orchestration (Kubernetes), and SaaS platforms (Vercel, GitHub, Linear)
