Checking domain names through threat sites eg https://otx.alienvault.com/

Hello

So I have been testing out the clean browsing DNS which seems to be working well, which looks great however there are some domains that I check on which seems to appear with malicious tags

Ive used AlienVault – Open Threat Exchange which runs a check on the domain which seems to appear with malicious tags, however DNS cleanbrowsing allows the domain in?

https://ibb.co/373t5Rb

Example one above which DNS cleanbrowsing has picked up a malicious domain which is great!

However other domains have come through without clean browsing hasn’t picked up on

what is the easiest way to make sure these domains come in and also what threat sites do you recommend?

Cheers
