Overview
Your security shouldn’t be a replay
Detection isn’t enough. Microsoft Defender coordinates protection across endpoints, identity, email, apps, and cloud—preventing, disrupting, and continuously improving defense.
- Integrate protection across your digital estate with a living security fabric—connecting signals, coordinating response across domains, and continuously strengthening as threats evolve.
- Stop high-confidence threats at the control layer—automatically containing breaches, preventing lateral movement, and reducing impact in real time, without relying on brittle playbooks or waiting for human approval.
- Scale decisions with agents embedded in your workflows—bringing cross-domain context to every signal, continuously triaging, prioritizing, and driving response so teams move from backlog to action in real time.
