As reported by motion-news, on October 8, 2026, Anthropic introduced the OSS Scanner—a no-cost AI security scanning service tailored for open-source software projects that opt in voluntarily. Utilizing Anthropic's most advanced model, this service offers comprehensive and regular security assessments for open-source endeavors, entirely free of charge. This initiative falls under the umbrella of the Anthropic Cyber Mission, which is dedicated to employing tools, research expertise, and resources to empower defenders in safeguarding vital infrastructure and open-source software.

The OSS Scanner dispatches automated vulnerability reports, crafted by Anthropic's sophisticated language model, to the participating projects. These reports encompass detailed information on vulnerabilities, potential exploitation techniques, and recommendations for mitigation. Project maintainers at the core level are required to proactively apply for this service, and the projects themselves must demonstrate a substantial influence on infrastructure or user security to qualify.
