Community Pulse
Advanced Ratings
Pros
- Totally free and pre-installed on Windows 10/11, requiring no setup, subscriptions, or third-party software to run.
- Tight integration with Microsoft's 2026 "Identity Security" enhancements protects against pass-the-hash and other corporate-style attacks often missed by consumer AV.
- The "Core Isolation" and "Memory Integrity" features lock down Windows kernel processes, preventing malware from embedding deep into the OS.
Cons
- Independent lab scores lag behind competitors; while "Ok," it doesn't achieve the 99.9% detection rates of Bitdefender or Kaspersky against zero-day exploits.
- The configuration interface splits between the "Security" app and the deep "Group Policy" editor, making advanced hardening difficult for average users.
- It lacks an integrated VPN, Password Manager, or encrypted cloud storage found in premium suites like Norton 360.
