If I upload a file for Sandbox behavioral analysis, does it always get detonated?

I’m just wondering if I upload a file to the Sandbox, does it always get detonated in the cloud sandbox?

In short, no. In some cases, a file that is uploaded via http://filecheck.zscaler.com/ is not actually detonated in the Cloud Sandbox.

  • The file sample must be no greater than 20 MB in size in order for it to be analyzed in Sandbox.
  • The file must be uploaded from a network and organization that is a paying customer of Cloud Sandbox subscription.
  • The file must not be blocked by anti-virus or other Zscaler Advanced Threat Protection security inspection layers. If it is, the file sample will not “reach” the Sandbox.
  • The file must be of a supported file type.
  • Last, but not least, the file must also not already have a Sandbox verdict. It the file has already been detonated in the Cloud Sandbox, and has a Sandbox verdict and detail behavioral analysis report available, it will not be submitted to the Sandbox for re-detonation.
