About this tag
Reputation-based protection in Microsoft Defender helps block suspicious apps, dangerous downloads, phishing attempts, and potentially unwanted apps by checking their reputation against Microsoft's security intelligence. This feature is part of Windows Security's App & Browser Control and is available in Windows 10 and Windows 11. It adds an extra layer of defense without requiring third-party software. Related features like Smart App Control in Windows 11 use cloud intelligence, code-signing checks, and machine learning to make allow/deny decisions, though with trade-offs for developers and power users. Configuring reputation-based protection is a straightforward way to enhance system security.
