web categorization question

I've been administering these things for a while now but I still can't say I really understand how their categorization works.


One site came to my attention today which appears entirely benign.    Visit it from a web gateway appliance, and it says it's pornography.   It actually seems to be an aggregator site of news and interesting stories and the like, as is all the rage it seems.


I checked      and it shows for the resident gateway appliances, Uncategorized, but if you check it against McAfee Realtime or SiteAdvisor Enterprise,  it says Pornography.


So...   can someone explain in a paragraph, the difference as it pertains to a web gateway appliance users' experience, or these different databases?   And how the web gatweway comes to a category determination that shows on error pages for people?   I'd like to know what aspect is the database that gets copied down regularly to the appliances, vs what "GTI" does, etc.


Thanks in advance  for any clarification!

    Re: web categorization question

    There are a limited number of URLs in the database on-box. ~40 million

    There are roughly 11 times more that reside on the GTI cloud. ~400 million


    When a URL.Category is looked up, it consults the local database first, then the online database.



    At some point in time, that site might have contained adult content and was flagged.

    No one has looked at it since and wanted it reverted back.

    If you request a site review, they will look at it again and change it.

    Re: web categorization question

    Hi Regis,


    I'm a little confused as to the wording, but I think you're just asking how come there is a difference between resident and cloud databases?


    resident = database downloaded to local web gateway

    cloud = database on mcafee servers


    The resident database is downloaded in order to prevent the MWG from needing to lookup every URL in the cloud. In addition, the resident database has a maximum size restriction (due to legacy devices, memory restrictions, and trying to keep a lower footprint on the appliance OS, etc...).


    The cloud helps with this because it can be whatever size it needs to be, and helps where the resident may not be updated as often. So MWG is configured to check the cloud when the MWG encounters an uncategorized URL (per the resident database).


    Does this help?


    The example you have given above simply looks like a miscategorization.

    Re: web categorization question

    Items in the resident are a subset of what's in the cloud.


    So everything that's in the resident is in the cloud, but not the otherway around.


    If you selected resident, I think they'll address it in related resident databases as well as the cloud.
