- Integration with Microsoft Defender endpoint protection.
Intune helps IT and security teams apply consistent policies across managed devices and reduce risks associated with insecure configurations.
7. Microsoft Defender AI Agent Security
As organizations deploy AI agents that can access enterprise data, execute tools, and perform tasks, those agents introduce additional security considerations.
Microsoft is expanding Defender capabilities to help discover AI agents, assess their security posture, and monitor potentially risky behavior.
Relevant capabilities include:
-
- AI agent discovery and inventory.
-
- AI agent posture assessment.
-
- Detection of suspicious agent interactions.
-
- Runtime protection for supported agents and tools.
-

- Controls intended to reduce risks from prompt injection and unsafe tool use.
Some of these capabilities were introduced in preview during 2026, so organizations should confirm current availability, licensing, and supported environments before deployment.
Building a Unified Microsoft Security Architecture
A modern security architecture can combine these technologies according to organizational requirements:
-
- Microsoft Sentinel: Security information and event management, threat analytics, and security automation.
-
- Microsoft Defender XDR: Cross-domain threat detection and response.
-
- Microsoft Defender for Cloud: Cloud posture management and workload protection.
-
- Microsoft Security Copilot: AI assistance for security analysis and investigations.
-
- Microsoft Entra: Identity and access security.
-
- Microsoft Purview: Data protection, governance, and compliance.
-
