Microsoft launches its first cybersecurity model, plus a new agentic cybersecurity system

Microsoft expanded its AI security lineup with the launch of its first dedicated cybersecurity AI model and a new agentic cybersecurity system. The company says the offerings are designed to strengthen how organizations detect, investigate, and respond to threats.

The move shows Microsoft pushing deeper into AI-driven security as enterprise cyber teams face rising alert volumes and talent shortages. Agentic systems could shift cybersecurity tools from passive analysis toward more autonomous investigation and response workflows.
