Anthropic Expands Project Glasswing to 150 New Organizations

Anthropic announced on its website that it is expanding Project Glasswing, its collaborative cybersecurity initiative, to include about 150 new organizations. The program uses the Claude Mythos model to help partners identify and patch vulnerabilities in critical software systems.

The new participants span more than fifteen countries and represent key sectors such as power, water, healthcare, communications, and hardware. Many are vendors or nonprofits maintaining software used by governments and infrastructure providers. Each organization must meet Anthropic’s security requirements before gaining access to the program.

Project Glasswing partners have already used the Mythos Preview model to locate over ten thousand high or critical severity flaws. Anthropic is now releasing additional tools to trusted security teams to accelerate vulnerability detection and patching. The company has also introduced a product called Claude Security, which employs its public models, including Claude Opus 4.8, to scan codebases and propose fixes.

Anthropic stated that it plans further expansions of Project Glasswing, prioritizing essential infrastructure providers and maintainers of critical open source software. The company is also preparing to broaden access to Mythos-class capabilities once sufficient safeguards are in place to prevent misuse of the model’s cyber capabilities.
