Hi Sulman,I am not aware of a publicly available tool that does this for you, but there are publicly available test links for the URL categories:https://sitereview.symantec.com/#/category-testIf you wanted to create your own tool to check the categories, you could probably script it pretty easy. If you get a HTTP 403 back, you know it got blocked. Otherwise, if you got a HTTP 200 it was let through.
Hope that helps!
