Bringing the cybersecurity capabilities of Claude Mythos 5 to more defenders

Anthropic is expanding access to Claude Mythos 5's cybersecurity capabilities through Claude Security, partner integrations, and a new $35 million Defender Advantage Fund for open-source security projects. The company is implementing safety measures to allow defenders broader access to defensive outputs while maintaining guardrails against misuse of the model's offensive capabilities. These efforts aim to help more organizations identify and patch vulnerabilities before advanced AI models become widely available to malicious actors.
