Why keeping Microsoft Defender patched matters
Unpatched third-party applications are one of the most common ways attackers get in: 57% of breached MSP clients and 32% of ransomware cases trace back to a missing patch. Every Microsoft Defender release that fixes a security bug is public, so attackers see it too, and an out-of-date install becomes a documented way in. Tracking the installed version on every machine and closing the gap quickly is what turns a disclosed CVE into a non-event.
