Anthropic launches Cyber Mission for critical infrastructure and open-source security

Anthropic announced the Cyber Mission on October 8, 2026, describing it as a long-term commitment to support cybersecurity defenders with tools, research, and resources. Its initial focus is critical infrastructure and open-source software, through the Critical Infrastructure Defense Program and OSS Scanner.

The Critical Infrastructure Defense Program brings frontier Claude models, on-site engineers, and threat research to trusted providers serving critical infrastructure operators. Its founding partners are Accenture, Booz Allen, CrowdStrike, Deloitte, Dragos, Hitachi, Insane Cyber, Nozomi Networks, Palo Alto Networks, PwC, and Rockwell Automation. Anthropic says several partners are already working with Claude to fix vulnerabilities and help customers do the same. It also notes that operational technology often cannot be taken offline for patching, leaving known vulnerabilities unresolved for years.

For open-source software, projects enrolled in OSS Scanner receive periodic security scans from Anthropic’s most capable models at no charge. Reports include an exploit proof of concept, an explanation, and a suggested fix when available.

Anthropic said it had offered frontier Claude models and technical support to more than half of U.S. states since launching a cyber defense program for state, local, tribal, and territorial governments in June. It plans to bring the Critical Infrastructure Defense Program to more partners and sectors over the coming months. The announcement follows Anthropic’s October 7 expansion of its Cyber Verification Program, which combined Project Glasswing and its earlier program into three access tiers for qualifying security professionals.
