Anthropic Expands Mythos Security Program to 150 Organizations Across Critical Infrastructure

Anthropic is expanding Project Glasswing — its AI-powered security vulnerability program built on the Mythos model — to 150 organizations across 15 countries, targeting critical infrastructure sectors including power, water, healthcare, and communications. The expansion focuses on infrastructure where a successful cyberattack could affect up to 100 million people. Approximately 50 companies had access to Mythos previously, and those organizations collectively found thousands of vulnerabilities in their own products. This is Anthropic’s most significant deployment of Mythos outside of internal use to date.
