WebGateway - AV scanning limit

Hello!

Could someone tell me what is the biggest file size that the antimalware engine can analyze?

Thanks,

Re: WebGateway - AV scanning limit

Hi ​,

i do not know the offizial size, but i tested with a 4GB ISO file where an 8 times zipped icar was included. GAM was able to detect and block.

Just note, scanning such big files needs some or more storage on MWGs disc. Because, if you have a multiple time compressed file and the file includes compressed files again, the used space on disk could be huge.

I often to this:

- changing to the alternate disc schema using mwg-cache-wizard.

- implementing a rule to block the request if there are to many files or to many levels in a compressed file.

Hope this helps,

Cheers
