Why does the Microsoft Edge browser report my site as dangerous or unsafe?

Question

When I visit my site in the Microsoft Edge browser, the browser reports it as dangerous or unsafe. Why is this?

Answer

The Edge browser employs Microsoft Defender SmartScreen to help identify potentially malicious websites. If a particular website has been reported as dangerous by other Microsoft Edge users, it can be identified as dangerous or unsafe by the browser.
