The most valuable features of the solution stem from web filtering, malware protection, and antivirus.

The Zyxel Unified Security Gateway solution is stable and does its job effectively. These are the main advantages I can confirm.

This is a capable appliance and the standard features work well for us.

The solution is good for freelance and routing, as we don't have a separate router.

It's usable for me, for my purposes. 

There are some filtering options such as peer-to-peer blocking and things like that.

The solution can scale well.

The cost is very low.
