Build a patch strategy for today’s threat pace with Microsoft

AI-accelerated vulnerability discovery and remediation are changing how organizations manage risk. As discussed in Pavan Davuluri’s recent blog, Microsoft is investing across the vulnerability lifecycle to help organizations identify, validate, and respond faster.

For IT and security teams, one challenge lies downstream: deploying fixes quickly across endpoints to reduce exposure. Each update needs to be evaluated, piloted, monitored, and enforced across a mixed fleet of devices and apps. Some parts of the estate can move quickly; others cannot because of compliance requirements, approved change windows, and business-critical dependencies.

As organizations adopt AI tools and agents across their environment, maintaining a current and hardened endpoint estate becomes increasingly important. In this context, patching becomes an ongoing operational discipline that combines OS, app, and driver updates with compliance enforcement, access control, and security baseline hardening.

To keep pace, organizations need a patch strategy that helps in 3 stages:

1. Mitigate: automate updates that can move quickly
2. Assess: prioritize risk based on exposure and severity
3. Contain: enforce compliance and limit exposure

Operationalizing a patch strategy requires coordinated capabilities across endpoint management and security tools. Microsoft Intune brings these capabilities together in a single admin center, alongside the broader Microsoft security ecosystem, and is available with qualifying Microsoft 365 subscriptions¹.

In this post, we show how organizations can use these capabilities to build a patch strategy that helps reduce the time between update release and deployment across their endpoint estate.

1. Mitigate: automate updates that can move quickly

A patch strategy is not about pushing every update everywhere at once. It’s about identifying the parts of your estate that can move quickly, then using automation, rings, monitoring, and enforcement to help those updates move with confidence. Regulations, approved change windows, validation needs, and business dependencies will shape what’s possible, but the strategy starts by separating repeatable update work from the exceptions that need deeper review.

For OS, app, and driver updates that can move quickly, modern tools can help shorten the time between update release and deployment; without manual rollouts, ticket-driven packaging, or reboot disruption.

Operationalize in Intune

• Windows Autopatch orchestrates ring-based update rollouts to reduce manual effort and keep Windows devices current. To help monitor risk, the Autopatch report visualizes how quickly devices apply updates based on the configured deployment cadence. In this report, devices are categorized as current within three days of update release, at risk between three and seven days, and at critical risk beyond seven days, based on the reporting model used by Windows Autopatch. Learn more about ring-based rollout updates or how to reassess Windows OS updates using this report.
  
  
• Hotpatch (enabled by default for 24H2+ in Intune) applies critical updates without requiring a reboot, helping reduce security gaps while keeping users productive.
  
  

  Figure 1: Watch the latest Microsoft Mechanics episode to see how Windows Autopatch and Hotpatch help organizations accelerate update deployment, reduce operational overhead, and keep devices secure.

• Intune Enterprise App Management (EAM) supports keeping Windows apps current through auto-updates, including the guided upgrade supersedence reporting, which surfaces outdated versions or version changes. EAM auto-updates are now generally available; details are included in the June Intune What’s new blog.

• The enhanced application inventory in the All apps page shows the app version installed on each managed Windows device, refreshed multiple times per day on most active devices, helping teams target app-specific vulnerabilities and confirming when fixes have been applied.
  
  
• The Vulnerability Remediation Agent in Security Copilot uses data from Defender Vulnerability Management to prioritize Common Vulnerabilities and Exposures (CVEs) across Intune-managed Windows devices and apps, and provides recommended remediation actions within Intune. The Vulnerability Remediation Agent is currently in public preview, read the blog to learn more.

Extend across your endpoint estate

• Apple devices can be configured for automatic OS updates on managed devices, including enforcing updates to the latest version and deploying Background Security Improvement patches through the settings catalog. App updates can be managed by configuring volume-purchased App Store apps to update automatically and deploy updated app packages to keep apps current across macOS, iPhone, and iPad devices.
  
  
• Android devices can be managed using built-in update policies in Intune, including configuring install windows and freeze periods. For corporate Android fleets, Intune also integrates with OEM firmware management solutions - including Zebra LifeGuard Over-the-Air and Samsung E-FOTA - to enable more granular update control. Managed Google Play also supports configurable app auto-update modes, allowing admins to define whether updates install automatically, on Wi-Fi only, or manually.

2. Assess: prioritize risk based on exposure and severity

The first step is reducing exposure across the parts of your estate that can move quickly. But not every system, application, or vulnerability can be addressed through broad update deployment. Teams also need a way to determine which risks require immediate action and which ones can be addressed over time.

A calendar-based approach can treat every CVE equally. However, it doesn’t account for severity, exposure, or business impact. As AI accelerates vulnerability discovery, this can lead to effort being spent on lower-risk updates while higher-risk updates remain unaddressed.

Risk-based service level objectives (SLOs) help bring prioritization to address this challenge. Instead of patching on a fixed schedule, IT and security teams can align response timeframes by severity, moving quickly on actively exploited or critical vulnerabilities, and applying a more measured approach where risk or impact is lower.

This stage creates a clearer prioritization of remediation and helps bridge the view between the security teams that identify threats and the IT teams that act on them.

Operationalize in Intune and Microsoft Defender

• The security update status dashboard in Intune provides an aggregated view of update compliance across Windows clients, Windows servers, and Microsoft 365 Apps. It shows overall counts of devices in different states across Intune-endpoints and helps teams identify where remediation should be focused. These status categories reflect how quickly devices apply updates based on a configured deployment cadence and internal SLOs.
  
  

  Figure 4: Security update dashboard showing patch status for Windows clients, servers, and Microsoft 365 apps.

• Microsoft Defender Vulnerability Management surfaces CVEs, affected devices, vulnerable software, and recommended remediation actions, offering a shared view of risk and progress across IT and security teams.
  
  
• Translate Defender recommendations into targeted Intune actions described in the mitigate section, such as updating software or moving devices through expedited remediation workflows so teams can focus on vulnerabilities that are actively exploited or most likely to affect an organization.
  
  

Extend across your endpoint estate

• For Apple devices, use the Apple software update report in Intune to monitor update status across macOS, iOS, and iPadOS.
  
  
• For Android, compliance reporting surfaces devices that fall behind on OS version or security patch level.

3. Contain: enforce patch compliance and limit exposure

Even with automated deployments and prioritized triage, gaps can remain. Some devices are unsupported, fall behind, operate on slower deployment rings, and others can’t be patched quickly. A patch strategy needs to focus on including containment for those surfaces.

Compliance controls, conditional access, and device hardening act as an always-on safety net that limits risks that can fall through gaps. Compliance policies and Conditional Access can use a patch state as a signal for resource access, preventing non-compliant devices from accessing corporate resources. Security baselines reduce the attack surface by limiting risky defaults and common attack patterns. Together, these controls shift enforcement from a periodic activity to a continuous condition across a fleet.

Operationalize in Intune and Defender

• Use compliance policies in Intune to define what "current" means, including minimum OS build, required update levels, risk status, and encryption state.
  
  
• Use Conditional Access (managed in Microsoft Entra, accessible from the Intune admin center) to control access to company resources based on user and device health. Combined with threat signals from Microsoft Defender, these policies help prevent non-compliant devices from accessing corporate resources.
  
  
• Use Microsoft Defender Vulnerability Management and Microsoft Security Exposure Management insights to identify exposed assets, prioritize remediation, and apply recommended protections where patching must move more slowly.
  
  
• Apply Intune security baselines to establish Microsoft-recommended configurations on Windows devices, such as disabling risky defaults, blocking common attack techniques, and reducing configuration drift. Watch this demo on security baselines being applied in the Zero Trust workshop.
  
  
• Use attack surface reduction policies in Intune to deploy Microsoft Defender for Endpoint protections, such as ASR rules and network protection, that help block common attack techniques on devices that can't be patched right away.
  
  

  Figure 5: Watch this Demo on how you can manage devices and implement Conditional Access with Intune.

Extend across your endpoint estate

• Compliance policies and Conditional Access controls apply across Windows, macOS, iOS/iPadOS, and Android.
  
  
• Intune app protection policies extend compliance requirements and data protections to managed apps used for work on personal devices and add an additional layer of data protection on corporate devices.
  
  
• Use the settings catalog and configuration profiles to apply the same hardening intent on macOS, iOS/iPadOS, and Android, reducing configuration drift across platforms.
