Microsoft Launches AI Cybersecurity Model, Targets Rivals

Microsoft unveiled MAI-Cyber-1-Flash, its first cybersecurity-specialized AI model, alongside a new agentic security platform called Perception at a San Francisco event. The company claims its model outperforms competitors including Google and OpenAI on the Cyber Gym benchmark, with CEO Mustafa Suleyman announcing immediate production deployment. Perception deploys red, blue, and green AI agent teams to simulate attacks, detect vulnerabilities, and automate fixes — reducing work that previously took hours to minutes. The tools will enter preview on November 3, competing in a growing field that includes Anthropic's Mythos and OpenAI's Daybreak security platforms.
