Anthropic has launched Cyber Mission, a long-term program to defend critical infrastructure and open-source software from cyberattacks, and with it a free vulnerability scanner for open-source projects. The tool, called OSS Scanner, was announced by the company and reported by Engadget and The Decoder. Projects that opt in receive periodic security scans powered by Anthropic's strongest models at no cost.
The move matters because nearly all modern software rests on open-source code, much of it maintained by small volunteer teams with no security budget. Anthropic's own announcement frames it as evening the odds: attackers already have powerful AI models, it argues, while defenders still lack comparable tools.
What Cyber Mission and OSS Scanner actually do
Cyber Mission is split into two efforts. The Critical Infrastructure Defense Program gives operators of essential systems access to Claude models, engineers and threat analysis, with CrowdStrike, Palo Alto Networks, Deloitte and Rockwell Automation as founding partners. The second effort is the free OSS Scanner for open-source software.
Anthropic says the scanner will regularly check participating projects, automatically flag and explain vulnerabilities, and suggest patches, with an expected accuracy above 90 percent. The company was inspired by OSS-Fuzz, the open-source scanner created by Google and the Open Source Security Foundation and available since 2016. Anthropic already sells a paid product, Claude Security, that handles general code scanning and patching; OSS Scanner performs similar audits for free.
- Critical Infrastructure Defense Program (CIDP): gives operators of power grids, water systems and transportation networks access to Claude models, Anthropic engineers and threat analysis.
- Founding partners: CrowdStrike, Palo Alto Networks, Deloitte and Rockwell Automation.
