Sucuri says the site is blacklisted but Defender says not blacklisted.

Can you tell me how exactly does the Defender Blacklist monitor check if the domain is blacklisted or not? Sucuri says the site is blacklisted but Defender says not blacklisted on my recently cleaned site.

    Hello Raymar ,

    I’m sorry about this problem.

    Defender should check the status of the domain in https://transparencyreport.example.com/safe-browsing/search every 6 hours but it doesn’t see it is working on your site at all. Even with deactivation and activation this option again, it’s not checked.
    I can see that debug.log is not created on your site, so it doesn’t give us a clue why the monitor is not working on your site.

    In this case, I will escalate this to the Second Live Developers to check this issue further and see what is going on.
    We will keep you posted.

    Also, can you tell me if you have a backup from before this issue happen?

    kind regards,
    Kasia

    Hello Raymar.

    I checked your site over Sucuri and seems to be marked as safe one. :tada:

    As you are using Defender I totally recommend you to check the new security tweaks features and resolve Security Headers which Sucuri reports as missing (XSS Protection, Content Type sniffing, etc).

    As Defender and Sucuri uses different methods and standards to evaluate a site’s status, results may differ sometimes. Always pay attention to the issues reported and resolve them to regain site’s whitelist status.

    Let us know if you need further help. :blush:

    Kind regards,
    Alex.
