Privacy and Security Enable or Disable Microsoft Defender SmartScreen Phishing Protection in Windows 11

  • Staff

Microsoft Defender SmartScreen protects against phishing or malware websites and applications, and the downloading of potentially malicious files.

Starting with Windows 11 build 22593, Microsoft is introducing two powerful new features that strike against the most common cyberattack techniques: phishing and targeted malware. New in Windows 11 is enhanced phishing detection and protection built into Windows with Microsoft Defender SmartScreen. This new feature will help protect users from phishing attacks by identifying and alerting users when they are entering their Microsoft credentials into a malicious application or hacked website. Smart App Control uses code signing alongside Microsoft’s powerful artificial intelligence models to ensure that only trusted applications are run, blocking one of the largest attack vectors on Windows by-default.
