If you were previously used to SonicOS then you need to tweak a bit and find out where they are now. In terms of functionality, however, it does the same. I'm not a fan of all the extras, so I'm looking for basic firewall functionality. I would have preferred Sonicwall for a lower price without unnecessary services (like intrusion prevention, antivirus gateway, etc.).
