Defender XDR: Tables not supported for table management
I am trying to extend the table retention of specific tables to allow them to flow to Sentinel Analytics but keep getting the message "This table is not supported for table management" in the Sentinel > Configuration > Tables page. The Sentinel workspace is connected in System > Settings > Microsoft Sentinel. I can see the table type is XDR in the list which seems to be the reason why it can't be managed. Any ideas why this table is not able to be managed.Monthly News-August 2026

Hello, I see that Copilot for Security in XDR dashboards , if used in embedded mode (I mean whenever you are opening a case to investigate) you get AUTOMATICALLY a summary of the incident , and you are consuming SCU costs. I want a way either globally as a tenant option, or through a pwsh to be able to DISABLE this, or be able to PRESS the AI button AND THEN generate the AI reply (and consume SCU credits ..) Current behavior: Open Incident --> Copilot automatically generates Incident Summary --> SCUs ARE consumed Desired behavior: Open Incident --> No AI execution --> Click "Generate Summary" MANUALLY --> SCUs consumed I am not talking about RBAC controls to assign WHO of my admins can use Security Copilot, I have set that, BUT I want my admin to decide IF they want AI to help them (and consume - pay for that SCU credits-costs) OR NOT !! At the moment I havent found any solution, except to educate my admin to press CANCEL the moment he/she opens such an XDR dashboard ! :) Does anyone knows something ? Regards, Panos
Prompted to sign in to Microsoft Defender Platform on W11/W2025 using Entra
Hi Microsoft Defender XDR community, Since around May 18th, our users on devices that are onboarded to Microsoft Defender for Endpoint are being prompted to sign-in to the following application using Entra on login to Windows. Application Microsoft Defender Platform Application ID cab96880-db5b-4e15-90a7-f3f1d62ffe39 Is anyone aware of a change that requires user sign-in to Entra as a requirement for Microsoft Defender for Endpoint? I have tried raising a support topic on this topic. Regards Chris

Hello all, I’ve been building something over the past few weeks that I think the security community might find useful. https://goxdr.fyi is a searchable KQL query library for Microsoft Sentinel and Defender XDR. The name comes from a nickname my colleagues gave me (GoX) combined with XDR. I also picked up https://goxdr.fyi as a short and easy to remember domain for it. You can check it out here: https://goxdr.fyi The idea came from my own day to day work as someone working in IAM and SOC operations. I constantly find myself writing and refining KQL queries for threat hunting, detection engineering and incident investigation. Over time I realized I had a growing collection of queries that I kept going back to and I thought why not make these available to others? It currently has 117 queries covering identity security, BEC/AiTM detection, NTLM and LDAP attack hunting, OAuth governance, AI/Copilot security, Sentinel alert trending, SOC performance metrics and more. Some of these queries are ones I wrote from scratch based on real scenarios I encountered in production environments. Others are community queries I tested and validated in my own setup. Only the ones I found genuinely useful and that actually worked against real data made it in. Each query comes with a description explaining what it detects and why it matters, along with severity levels, platform tags (Sentinel, XDR or both) and a copy button so you can paste it directly into Advanced Hunting or use it as the basis for an Analytics Rule. The site is open source, hosted on GitHub Pages and licensed under CC BY 4.0. No sign-up, no paywall, no tracking. The source is available. I’ll keep adding queries as new scenarios come up. If there’s enough interest I’m also considering adding Cortex XQL queries for Palo Alto environments. Suggestions, feedback or ideas for new detections are always welcome. Feel free to reach out. Thanks
Introducing scheduled antivirus scans on Microsoft Defender Linux
Security teams rely on scheduled scans to ensure consistent coverage across devices, detect dormant or missed threats, and meet compliance requirements. However, managing scans on Linux has traditionally required custom scripts and cron-based setups, which can be hard to scale and maintain. That’s why we’re excited to introduce centrally managed scheduled antivirus scans for Linux in Microsoft Defender. With this release, we are bringing built-in, flexible scheduling capabilities directly into Defender - making it easier to manage and standardize scan behavior across Linux environments. What’s new With this capability, customers can now configure scheduled antivirus scans on Linux using security settings management policies in the Microsoft Defender portal for centralized policy enforcement or local Managed JSON configuration that can be deployed via configuration management tools like ansible, puppet and chef. The feature supports a flexible set of scheduling options, including hourly quick scans (interval-based scheduling), daily quick scans at a defined time, and weekly scans with configurable scan type (quick or full). In addition, customers can control how scans run with advanced options such as: Running scans only when the device is idle Reducing CPU impact using low CPU priority Checking for definition updates before scanning Randomizing scans start times Ignoring exclusions during scheduled scans These capabilities allow security teams to balance coverage, performance, and operational needs across large Linux environments. Why this matters From a security perspective, scheduled scans play a critical role in detecting dormant threats, missed detections, and malicious artifacts that may not be caught through real-time protection alone. Without consistent and centrally enforced scheduling, these gaps can increase risk across the environment. With this release, scheduled scans are now: Centrally managed through Defender policies Consistently enforced across devices Aligned with security best practices for regular scanning Integrated into the broader Defender security posture This helps organizations strengthen their overall security posture while reducing operational complexity. Get started To get started, ensure devices are running agent version 101.26032.0000 or later (production ring), and configure scheduled scans using managed JSON or Defender portal policies.
