​​​​What’s new in Microsoft Security: November 2026

Security teams also need a clearer view of expert-led protection and a simpler way to deploy SQL Server protection in Azure Government.

Endpoint administrators need to keep elevated access accountable at scale. Security teams also need a clearer view of expert-led protection and a simpler way to deploy SQL Server protection in Azure Government. The useful part sits in the context, the practical impact, and what readers can use to decide the next step.

​​​​What’s new in Microsoft Security: November 2026

Endpoint administrators need to keep elevated access accountable at scale. Security teams also need a clearer view of expert-led protection and a simpler way to deploy SQL Server protection in Azure Government.

What happened

As AI agents gain access to business data and tools, organizations need ways to limit their authority and adapt protection as risk changes. This month’s Microsoft Intune and Microsoft Defender updates introduce capabilities across these areas, alongside new Secure AI capabilities for agent access. A recent Secure Now update in Microsoft Security Exposure Management also connects information on recent threats to focused initiatives for reducing exposure.

Where the sources line up

As agents gain access to business data and tools, organizations need ways to manage what each agent is allowed to do. Dynamic Permissions provides an agent its own permissions and authority, scoped to its current task and for only as long as the task requires. As the agent works, Dynamic Agent Risk assesses whether the agent’s authority aligns with changing behavior and context. Dynamic Conditional Access can then respond proportionately by narrowing permissions, restricting access to resources, or requiring human approval for higher-impact actions. Together, these capabilities are designed to help organizations tailor agent authority before an agent acts and adjust access as risk changes.

Practical impact for readers

Microsoft Execution Containers (MXC), now generally available, gives organizations an operating system-enforced containment layer for AI agents, designed to limit what an agent can access. Rather than relying on the agent to behave within intended boundaries, MXC applies least-privilege controls across files, networks, processes, and user interactions, with additional isolation options for higher-risk scenarios. Organizations can tune and validate policies before enforcing them broadly, while upcoming integration with Microsoft Intune, Microsoft Entra , and Microsoft Agent 365 is intended to extend governance and attribution across the enterprise.

Who should pay attention now

Microsoft Intune Endpoint Privilege Management continues to expand the tasks standard users can complete without broad administrator rights. With new system settings support, standard users can change IPv4, IPv6, and DNS server values on their device’s network adapters through Endpoint Privilege Management, while administrators determine how those changes are elevated. For user-confirmed changes, administrators can require a business justification, Windows authentication, or both before the change is applied. Along with tenant onboarding updates, these improvements support organizations as they get started with and expand their use of Endpoint Privilege Management.

What is still unclear

Get started with Microsoft Intune Endpoint Privilege Management Simplify security operations with Defender Experts See what Defender Experts are investigating in a consolidated experience As threats move faster and security environments grow more complex, security teams need to quickly understand what matters and when to act. New Microsoft Defender Experts MDR experiences in the Microsoft Defender portal bring ongoing expert work into focus with a consolidated overview page with updated navigation and visibility into hunts. Teams can review active and completed hunts, see findings from Defender Experts, and identify items that may require follow-up.
