Quality of Brightcloud URL categorisation or lack of.

L1 Bithead


Has anyone else found that there are a large number of websites being classified as Job Search when they are blatantly not? We are finding this to be the case and in fact are generally finding the classifications to be a bit hit and miss in places. Our previous URL filtering solution used the Smartfilter database and we never really had any problems with that.

Any opinions??

We have had precision issues with Brightcloud as well; I brought it up to our SE.

In general I would say accuracy is lacking.

Regarding the not-resolved issues, there's a known issue in 3.1 code surrounding not-resolved URLs. We anticipate a fix for the issue in 3.1.6. If you are seeing high numbers of not-resolved URLs, please contact support.

well, I have a ticket with them. Lets see if they can put this to bed...

as yet nothing back from them, sent our support logfile over to them yesterday afternoon.

In PANOS 3.1.6, we are getting good feedback with regards to fixing the error in getting unknown categories returned as "Not-Resolved".

In terms of the database in accuracies with regards to job-search category. Brightcloud are finalising the fine tuning of their engine in this area. The process and reclassification should be complete by the end of November 2010.

Coming from another categorization db vendor that was very good I am finding BrightCloud far more inaccurate. Our problem on several occasions was sites being categorized as Religion (which we block) and yet the BrightCloud lookup was categorized correctly. Our PA device was wrong! So what am I supposed to do then?

I am assuming that you have already verified that you are running the 3.1.6 PA software and the most up to date Brightcloud database (3491 is the latest version as of Nov 29, 2010).

If you are completely up to date on software and URL filtering database versions and still seeing this issue, you should open a case with PA technical support to resolve any issues where the database version on the firewall and the Brightcloud firewall are the same, but the query result is different.

I have to say that the Brightcloud URL Categorization needs quite some work. I have also experienced many categorization errors. Even when we re-categorizing these sites and they change, I have had a few that have gone back to the original category.

I think in my opinion it is time to use another vendor for your URL filtering, as the Brightcloud URL Filtering is quite weak in comparison to others out there. Or Brightcloud really needs to look at their competitors categories and the accuracy.

Upgrade to 3.1.6 scheduled for this weekend!

Thanks for the advice.

Today, all of a sudden (3.1.6) users are hitting the not-resolved url issue, then these sites were working perfectly yesterday.

I am not sure if I should raise a ticket for this or not?

Wondering if its brightcloud or palo?
