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 you click a malicious link in an email or navigate to a site designed to trick you into disclosing financial, personal or other sensitive information, or a website that hosts malware, Microsoft Defender Browser Protection will check it against a constantly updated list of malicious URLs known to Microsoft.
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.
