Anthropic is scaling up Project Glasswing, its AI-powered vulnerability detection programme, to around 150 new organisations across more than 15 countries — a significant expansion from the 50 initial partners granted access in April.
At the programme’s core is Claude Mythos, Anthropic’s most powerful model to date, capable of identifying thousands of zero-day vulnerabilities across weeks of scanning. The newly admitted organisations span critical infrastructure sectors including power, water, healthcare, and communications — industries underrepresented in the first cohort. Anthropic noted that a successful attack on any partner’s codebase could affect more than 100 million people with serious consequences for national and global security.
New participants reportedly include identity management firm Okta, South Korean technology giants Samsung, SK Hynix and SK Telecom, as well as NATO and the EU’s cybersecurity agency ENISA. The expansion covers allied nations including Australia, Germany, Japan, France and India.
The announcement follows Anthropic’s confidential IPO filing and a funding round valuing the company at nearly $1 trillion. Rival OpenAI has since released its own cybersecurity-focused model, GPT-5.5-Cyber, accelerating competition in AI-driven security.
