Difference between USG and firewall series

DMD

Hello everybody,

What difference have USG* and Firewall* Zyxel Models? Most of them seem to have similar features, so I can't decide what device should I use and when.

Which of them has the highest performance?

Thank you.

Hi @DMD,
Welcome to Zyxel Community.
It’s a little bit different. USG series is mainly focus on UTM service(Anti-virus, Anti-spam, IDP, and CF), those license are bundle by default.
Firewall(ZyWall) series is non-bundle, you have to purchase each license for UTM service, it depends on your requirement.
