We have a small company around 20-25 simultaneous users.
We have been using a Sonicwall TZ 210 for about four years. It finally quit on us which is pretty strange so we are on our backup unit. Now that they have been acquired by Dell I'm less excited about the brand though the TZ 400 sounds like an appropriate upgrade.
Was looking at the pfSense SG-2440. Much less expensive, but are the apps a hassle? I am hoping for set it and forget it. I do like the packet inspection, content filtering, and other features which are pretty simple on the Sonicwall.
Another option might be the Fortigate FG60D, but after attempting a presales call to their support team and not being able to reach anyone or get a call back when promised I've lost interest in that model.
I I will try to distribute points across answers that are helpful, thank you for your input!
