About this tag
The microsoft security tag on WindowsForum.com covers Microsoft's security portfolio and the practical challenges IT administrators face with cloud services and patch management. Recent discussions highlight Microsoft Security products like Defender XDR, Sentinel, Entra, Purview, and Security Copilot, alongside advisories for Azure services such as Service Bus, Logic Apps, and Cosmos DB where customer-side patches are unavailable. The tag also explores the impact of AI on security, including AI-agent containment guidance in Microsoft Secure Now, the growing vulnerability backlog reported in July 2026 Patch Tuesday, and the planned retirement of SMS and voice MFA in Entra. These threads emphasize the need for vigilance with cloud service advisories and evolving AI-driven threats.
