Microsoft Defender Browser Protection Extension

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.

Matthias Kuhn (ID: 00000044cd13ed4e) Voted 1 ★ - Updated 04/15/2024 Die App soll Schutz bringen, erzeugt allerdings nur Frust. Wenn jede dritte Website als verdächtig eingestuft und nicht angezeigt wird, bringt das ganze gar nichts.

Betty Sanchez (ID: 000000a67c7e5eae) Voted 1 ★ - Updated 11/21/2023 I didn't even know that I had this extension installed til I had a problem with it. I can't open ANY SINGLE web...All of the sudden, all of them are reported as unsafe. That can not be possible... I can't neither swicth it off or delete it. Result: I can't navigate at all using google chrome. If I use a different browser then I can. Obviously is not a problem of the website visited, but the extension.

Karen Roach (ID: 0000000b8f02a8d8) Voted 5 ★ - Updated 04/12/2023 I compared safe browsing apps. MS Defender compares your browsing to tables of known threat actors in realtime. Anonymously. Defender, on a Windows computer has very low overhead and if you are setup to automatically download and install via Windows Update it is always current. Google permanently logs all of your browsing, keyed to your Google email ID, if you add their Safe Browsing extension. Sounds like spyware to me.
