Key points

  1. Anthropic says the Cyber Mission starts with two areas: critical infrastructure and open-source software.
  2. The Critical Infrastructure Defense Program's founding partners include Accenture, CrowdStrike, Deloitte, Dragos and Palo Alto Networks, and it brings Claude models and on-site engineers to providers.
  3. OSS Scanner is opt-in and free; Anthropic says its reports are model-generated and sent without human review, and that it expects a true-positive rate above 90%.

What happened

Anthropic announced the Anthropic Cyber Mission on 8 October 2026, starting with two areas: critical infrastructure and open-source software. The Critical Infrastructure Defense Program gives providers that secure operational technology frontier Claude models, on-site engineers and threat research.

Its eleven founding partners are Accenture, Booz Allen, CrowdStrike, Deloitte, Dragos, Hitachi, Insane Cyber, Nozomi Networks, Palo Alto Networks, PwC and Rockwell Automation. OSS Scanner is an opt-in service that gives enrolled open-source projects periodic scans from Anthropic's most capable models, free of charge.

Each report carries a proof of concept, an explanation and a suggested fix where one is available. The reports are model-generated and sent without human review, and Anthropic says it expects a true-positive rate above 90%.

Anthropic also says it merged Project Glasswing into its expanded Cyber Verification Program earlier in the week.

What it means for you

Our view

OSS Scanner and the infrastructure program are Anthropic's own offers, and the accuracy figure is an expectation, not a measured result. Anthropic itself says the scanner's reports are sent without human review and some will contain inaccuracies, such as a wrong severity rating.

For maintainers that means a free source of findings that still needs a person to confirm each report before acting on it.

If you maintain open-source code or run operational technology, check what enrolling would send to Anthropic, who will triage the reports, and whether your existing vulnerability disclosure process can absorb them.

It adds no new facts.
