Anthropic is opening its closely guarded cybersecurity initiative, Project Glasswing, to approximately 150 new organizations across more than 15 countries. The expansion, first reported by The Indian Express, marks the program’s largest international rollout since its initial launch with a small cohort of U.S. and U.K. participants.
NCT previously reported on the tension between Anthropic’s Pentagon “supply-chain risk” designation and reports that Anthropic engineers were embedded at the NSA deploying Mythos for offensive cyber operations. This expansion adds a new dimension: Anthropic is now distributing the model to defensive cybersecurity agencies worldwide.
Who Gets Access in India
Four Indian government entities have received or are receiving access to Claude Mythos Preview, according to The Indian Express: the Indian Cyber Crime Coordination Centre (I4C), the Indian Computer Emergency Response Team (CERT-In), the National Critical Information Infrastructure Protection Centre (NCIIPC, which reports to the National Security Advisor), and the Department of Telecommunications’ Digital Intelligence Platform (DIP).
Anthropic has also extended access to cybersecurity-focused research institutions in India and is in discussions to provide Mythos Preview to dedicated security and AI teams at some of India’s largest IT services companies, a senior government official told The Indian Express on condition of anonymity.
What Mythos Does
Claude Mythos Preview is an unreleased AI model that Anthropic says can identify critical software vulnerabilities “at a level that could fundamentally alter the balance between cyber attackers and defenders.” Anthropic has restricted public access, citing concerns that its capabilities could be exploited if released broadly.
The new partner organizations, according to The Indian Express, operate in industries including power, water, healthcare, communications, and hardware. Many are vendors and maintainers of open-source codebases relied upon by governments and enterprises globally.
India’s Defensive Response
India’s government is treating Mythos as both an asset and a threat. Finance Minister Nirmala Sitharaman held a high-level meeting in April alongside IT Minister Ashwini Vaishnaw to assess risks the model poses to India’s banking sector, according to The Indian Express. Sitharaman directed the Indian Banks’ Association to develop a coordinated institutional mechanism for rapid response and instructed banks to engage top cybersecurity professionals to strengthen defensive and monitoring capabilities.
NCIIPC and CERT-In specifically requested Mythos access to identify vulnerabilities in India’s critical infrastructure, including banking and power systems.
The Dual-Use Tension
The expansion arrives against a backdrop of contradictions in Anthropic’s government relationships. On June 4, the Financial Times reported that Anthropic is helping the NSA deploy Mythos for “offensive cyber operations, embedding engineers inside the agency,” with one source saying Mythos “would be useful for infiltrating the networks of nations such as China or Iran.”
Simultaneously, Anthropic has drawn a red line restricting Claude models from use in mass surveillance of U.S. citizens and lethal autonomous drones. That stance prompted the Pentagon to designate Anthropic a “supply-chain risk,” a first for a U.S. business. Anthropic has sued over the designation.
The Scale of Glasswing’s Reach
With 150 new organizations joining, Project Glasswing moves from a controlled pilot to something closer to a global cybersecurity utility. Each new partner must meet Anthropic’s security requirements before gaining access, but the sheer number of entities now holding an unreleased frontier model with offensive and defensive capabilities creates its own governance questions: who monitors how 150 organizations across 15 countries use a model that can identify zero-day vulnerabilities?
Anthropic did not respond to The Indian Express’s request for comment. The company filed for an IPO last week at a reported valuation of nearly $1 trillion.
