I have had 2 Sonicwall Firewalls over the last 10 years, a TZ170 and my current firewall, a TZ210. I've had them configured per Sonicwall's suggestions but have never used their security suite. How safe are we? I use anti-virus on our computer level and have never been breached. (Knock on wood). The million dollar question is does a Firewall Appliance work without the intrusion prevention? I seems like it does. We are going to open up a second location and plan on buying a TZ300 and looking at just the appliance vs a year comprehensive security suite.
Any articles you can point me to would also be helpful.
