Anthropic launches a Cyber Mission: free vulnerability scans for open-source projects, frontier-model access for 11 named critical-infrastructure firms
OSS Scanner offers free, unreviewed vulnerability reports Anthropic expects to be right over 90% of the time; the Critical Infrastructure Defense Program gives Accenture, CrowdStrike, Dragos, Palo Alto Networks and eight other named partners access to Claude for power grids, water systems and transportation networks.
Anthropic announced the Cyber Mission on October 8, describing it as "a long-term commitment to securing the systems everyone depends on," starting with two areas: critical infrastructure and open-source software. It's a companion launch to the Cyber Verification Program expansion Anthropic announced two days earlier, but with concrete new programs and named partners rather than an access-tier restructuring.
Two programs, two different trust models
The Critical Infrastructure Defense Program (CIDP) gives trusted security providers -- Accenture, Booz Allen, CrowdStrike, Deloitte, Dragos, Hitachi, Insane Cyber, Nozomi Networks, Palo Alto Networks, PwC and Rockwell Automation are the named founding partners -- frontier Claude model access, on-site engineers, and threat research aimed at operational technology: power grids, water systems, transportation networks, plus government systems. OSS Scanner runs the opposite trust model: any enrolled open-source project gets periodic free scans from Anthropic's most capable models, with reports sent directly to maintainers "without human review." Anthropic says it expects a true-positive rate "above 90%" on those unreviewed reports -- a specific, checkable claim once enough scan cycles have run, and one worth tracking rather than taking on faith at launch.
The funding commitments underneath the announcement
Anthropic is funding the Python Software Foundation, Alpha-Omega and OpenSSF (through the Linux Foundation), and the Apache Software Foundation directly, plus Akrites and Gold Eagle, which coordinate vulnerability reports across projects. The Defender Advantage Fund, launched in August, is what keeps OSS Scanner free rather than a future paid tier. None of this comes with a disclosed total dollar figure for the Cyber Mission itself, which is the gap worth watching: a program built on "free access" and "unreviewed reports" is a bet that Anthropic can sustain both at scale, and the proof of that is in whether OSS Scanner's accuracy and CIDP's partner list still look the same a year from now, not in this launch post.
