Email & WatchGuard Firewalls

With Malware often being hidden within Zip files as an attachment to an email as an attempt to avoid detection by mail security software, it is important to have a solution in place that can interrogate these compressed files and determine whether their content is malicious or not.

The Gateway AntiVirus subscription service on a WatchGuard security device provides one such solution as it can temporarily decompress email attachments before scanning them.

To enable this feature you will need to do the following:

• Go into Policy Manager > Subscription Services > Gateway Antivirus and ensure that the Gateway AntiVirus service is enabled for your SMTP Proxy.
• Click Settings… > Enable Decompression before saving & writing the configuration to the device.
