# Anthropic launches Cyber Mission with free open-source vulnerability scanner

The initiative offers free AI vulnerability scanning for opted-in open-source repositories and provides frontier Claude models to critical infrastructure operators.

- OSS Scanner periodically scans open-source codebases and generates reports containing proofs-of-concept, explanations, and suggested fixes at no cost.
- The Critical Infrastructure Defense Program pairs frontier Claude models and on-site Anthropic engineers with power grid and water system operators and their suppliers.

## Why it matters

Open-source maintainers gain access to automated AI-driven vulnerability detection and patch suggestions without subscription fees.
