About Gateway AntiVirus Scan Limits
In the Gateway AntiVirus settings, the Scan size limit controls the maximum size of files that can be scanned by Gateway AntiVirus. Gateway AntiVirus does not scan files larger than the configured scan size limit.
Gateway AntiVirus default and maximum scan size limits are based on the hardware capabilities of each Firebox model.
Minimum scan size for all models is 1 MB.
| Default Scan Size Limit |
Maximum Scan Size Limit | RAM | Device Model |
|---|---|---|---|
| 2 MB | 10 MB | 1 GB | Firebox T15,, Firebox Cloud Small, FireboxV Micro, FireboxV Small |
| 5 MB | 20 MB | 2 GB | Firebox T20, T35, T55, T70, Firebox Cloud Medium, FireboxV Medium |
| 10 MB | 20 MB | 4 GB or more | All other Firebox models |
The scan limit also limits the maximum size of files that APT Blocker sends for analysis. APT Blocker can analyze files up to 10 MB in size. If you set the Gateway AntiVirus scan limit to higher than 10 MB, APT Blocker does not analyze files larger than 10MB. In Fireware 12.3 Update 1 or later, APT Blocker can submit the MD5 hash values of files larger than 10MB to the cloud-based data center. For more information, go to About APT Blocker.
If you enable DLP and Gateway AntiVirus for the same proxy action, the larger configured scan limit is used for both services.
For information about how to set the scan limit, go to Configure Gateway AntiVirus Actions.
Gateway AntiVirus can scan inside compressed files, such as ZIP files. For information about Gateway AntiVirus decompression, go to Gateway AntiVirus Global Settings.
