About Microsoft Defender Browser Protection

Currently supported region(s): United States The Microsoft Defender Browser Protection extension helps protect you against online threats, such as links in phishing emails and websites designed to trick you into downloading and installing malicious software that can harm your computer.

If the malicious link matches one on the list, Microsoft Defender Browser Protection will show a red warning screen letting you know that the web page you are about to visit is known to be harmful, giving you a clear path back to safety with one click.
