Anthropic launches cyber defense program for infrastructure and open source

Anthropic has started the Anthropic Cyber Mission, which includes a Critical Infrastructure Defense Program and an OSS Scanner service. The critical infrastructure effort pairs Anthropic's most capable models with on-site engineers and partners such as Accenture, CrowdStrike, and Palo Alto Networks. The OSS Scanner offers free security scans from Anthropic's strongest models to eligible open-source projects.

Anthropic's Cyber Mission has two parts. One pairs its most capable models with engineers embedded at critical-infrastructure organizations, alongside partners such as Accenture, CrowdStrike, and Palo Alto Networks. The other, OSS Scanner, provides free automated security reviews to qualifying open-source projects. Eligibility follows Google's OS-FUZZ criteria, focusing on widely used projects with major infrastructure or user-security importance.

Enrolled maintainers get recurring automated reports about possible exploits; no person reviews them first. Joining requires permitting inputs and outputs to train models under Anthropic's consumer terms. Anthropic says AI bug reports have shifted from mostly poor to high quality, and that LLMs now find over 85 percent of vulnerabilities, up from 20 percent in early 2025.
