Microsoft Defender Domain Exclusion

Microsoft Defender appears to be slowing down my Chrome browser when I try to use it on websites like HubSpot in the same browser. Testing these sites on an incognito window, they run much faster.

Where do I list websites where I don't want Microsoft Defender to run?

    To exclude specific websites from Microsoft Defender, you can create exclusions for IP addresses, URLs, or domains in the Microsoft Defender settings. Here’s how to do it:

    1. Open Microsoft Defender XDR.
    2. Go to Settings and then select Identities.
    3. In the left-hand menu, find Excluded entities.
    4. You can set exclusions by choosing either Exclusions by detection rule or Global excluded entities.

    Keep in mind that defining exclusions lowers the protection offered by Microsoft Defender, so you should evaluate the risks associated with implementing these exclusions carefully. It's advisable to use exclusions only for specific issues, such as performance or application compatibility problems.
