Anthropic expands Project Glasswing, its joint industry initiative to find and fix critical software vulnerabilities using AI, to approximately 150 new organizations in more than 15 countries, the company he said Tuesday.
The news comes a day after Anthropic announced it had filed confidentially for an initial public offering, following a $65 billion funding round at a nearly $1 trillion valuation.
Anthropic’s Claude Mythos is at the heart of Project Glasswing. The AI firm called the model its most powerful yet, capable of detecting thousands of zero-day vulnerabilities over several weeks. In early April, Anthropic gave 50 initial partners, including the US government, access to the Claude Mythos Preview to scan their codebases for vulnerabilities and security flaws.
The expanded list of organizations with access to Mythos as of today covers energy, water, healthcare, communications and hardware — industries that were not “well-represented” in Anthropic’s original cohort, the company said. Many who will now have access are companies or nonprofits that maintain codebases that other organizations and governments rely on, Anthropic noted in the blog post.
“What every partner has in common is that a successful attack on their code base could be devastating,” the company said. “For most partners, we estimate that a major attack could affect more than 100 million people, with significant implications for both global and national security.”
The expanded group includes organizations in US-friendly countries such as Australia, Canada, France, Germany, Italy, Switzerland, the Netherlands, Spain, Belgium, Sweden, India, Japan, New Zealand and South Korea. Financial Timescited person familiar with the matter.
The FT also cited several organizations that have been given access to Mythos, including: US-based identity management and security tool Okta; South Korean companies Samsung, SK Hynix and SK Telecom. NATO, the US-led military alliance based in Brussels. and the EU cybersecurity agency ENISA.
TechCrunch has reached out to Anthropic for confirmation.
Anthropic said it expects other AI companies to soon develop models capable of the Mythos Preview, which is why the company is fighting to put safeguards into Project Glasswing.
Since the release of Mythos, rival OpenAI has released its own cybersecurity-focused GPT-5.5-Cyber model, which it has made available to a large group of partners for testing.
