Microsoft’s CVE-2026-21710 entry is a textbook availability issue: the vulnerability description says an attacker can cause a total loss of availability in the impacted component, either by sustaining the attack or by triggering a condition that persists after the attack stops. That phrasing...

Microsoft has quietly but decisively retired endpoint-sensitive data alerting in the Microsoft Defender portal, forcing organizations that relied on those alerts to move their workflows into Microsoft Purview DLP. The change is not just a cosmetic portal reshuffle; it alters where admins build...

The Microsoft Security Response Center’s page for CVE-2026-32775 returns a blunt “page not found” message — and that single absence is the opening line of a far larger story about how modern vulnerability tracking, attribution and remediation can fail defenders at the moment they need it most...

DataBahn’s newly announced deep integration with Microsoft Sentinel promises to collapse SIEM onboarding timeframes and materially lower analytics‑tier ingestion costs — claims that, if realized broadly, would change how security teams plan SIEM migrations and manage long‑term telemetry...

Microsoft’s latest threat briefing — published March 6, 2026 — and a follow-up interview on March 8, 2026, make a blunt, unglossed point: attackers are already using agentic AI to outsource the tedious but mission‑critical work of running cyber campaigns, and that shift changes how defenders...

Microsoft’s latest push to marry autonomous defense with expert-led services forces a practical reckoning: modern SOCs can either adapt to a world of minute‑scale attacks or continue paying the growing operational tax of fragmentation, manual toil, and missed signals. Background / Overview...

Microsoft’s February update for Microsoft Sentinel introduces a dedicated Copilot data connector in public preview that brings Copilot audit logs and activity telemetry directly into Sentinel workspaces and the Sentinel data lake, enabling SOC teams to hunt, detect, and automate responses to...

Microsoft’s decision to fold System Monitor — Sysmon from the Sysinternals suite — into Windows 11 as an optional, inbox feature marks one of the most consequential changes to desktop monitoring in years. The functionality has begun appearing in Windows 11 Insider Preview builds (notably the Dev...

Microsoft has begun a public preview of a dedicated Copilot data connector for Microsoft Sentinel, a move that brings Copilot audit logs and activity telemetry directly into Sentinel workspaces and the Sentinel data lake so security teams can hunt, detect, and automate responses to AI‑related...

Microsoft has quietly moved one of the most powerful pieces of Windows forensic telemetry out of the Sysinternals download bucket and into the operating system itself: Sysmon functionality is now an optional, built‑in feature in Windows 11 and is rolling out to Insider Preview builds, bringing...

Microsoft has quietly folded Sysmon — the long-favored Sysinternals system-monitoring tool — into Windows 11 as an optional, inbox feature, delivering it through Insider preview builds and the Windows servicing pipeline rather than as a separate Sysinternals download. That change, which appears...
