Anthropic launches a Cyber Mission, with free AI security scans for open-source projects

Monday, 12 October 2026By Sridhar Mukkandi1 min read

Anthropic announced the Anthropic Cyber Mission on 8 October, a long-term effort to give defenders tools, research and resources, starting with critical infrastructure and open-source software. Its Critical Infrastructure Defense Program brings Claude models, on-site engineers and threat research to providers that protect systems such as power grids and water networks, with founding partners including Accenture, CrowdStrike, Deloitte, Palo Alto Networks and PwC.

For open source, an opt-in OSS Scanner gives maintainers of critical projects periodic free scans from Anthropic's strongest models. Each report includes a proof of concept, an explanation and a suggested fix where available. Anthropic says the reports are model-generated and sent without human review, and that it expects a true-positive rate above 90%.

So what

A true-positive rate above 90% still means some reports will be wrong, and they arrive without a human check. Treat each one as a strong lead to verify with its proof of concept, not as a confirmed bug, and decide in advance how many your maintainers can review.

Models Anthropic releases Claude Haiku 5.5, its cheapest and fastest small modelAt $0.10 per million input tokens, a capable small model makes it cheap to put a model on every routing and classification step of an agent. Cheap steps multiply, so check how often its answers are right at the confidence you act on before you let it decide alone. Anthropic Policy Anthropic updates its usage policy, with new rules on surveillance and autonomous hardwareIf you build on Claude, check your use cases against the new surveillance and high-risk sections before 12 November. The hardware rule is a useful pattern for any agent that acts in the world: a person who can watch and stop it, and a safe state when the model is unreachable. Anthropic Models Cloudflare releases Clef, open decision models that answer with probabilitiesThe probability is what makes a decision model useful: code can act on a confident answer and hand a borderline one to a person. Check how well those probabilities match reality on your own data before you pick the cut-off. Cloudflare blogAll stories
