Having issues with Windows Defender SmartScreen? We can help!

The Microsoft Windows Defender SmartScreen (opens in a new window) is a security filter for malicious and potentially suspicious websites. Unfortunately, this service sometimes results in false positives on Windows Defender's part–causing a misinterpretation of a safe KnowBe4 landing page, and flagging it as malicious.

If you or your users clicked on a link in a simulated phishing security test email and received an "unsafe" warning (as shown below), contact our Support team and we'd be happy to assist with alternative phishing test options.
