What do you like best?
One of the keys to good security is visibility. Watchguard provides a wealth of well designed tools that give you a clear picture into your first line of defense.
The Firewall itself has a range of security options and security layers that can be implemented and adjusted according to your environment.
The policies are easy to set up and manage, and Watchguard's online documentation is outstanding.
For the most part the support is well trained and helpful, I haven't had any major support problems in the 6 years I've been a customer
What do you dislike?
If you submit a support case online, sometimes it can take 24-48 hrs before it gets picked up. I've had good sucess submitting a case online, then calling a few hours later if it hasn't been assigned to a tech.
The licensing process is a bit of a chore, but it's not a huge problem since it's only done annually at most.
