We're getting a new firewall for our company and I wanted to get some input from the experts. We're replacing our main firewall at our headquarters. It's a SonicWall NSA 220 that is connected by VPN to other SonicWalls (different models) at remote jobsites. We're a construction company and we use SharePoint and upload/download large drawing files throughout the day. We're expanding and want to be sure the new firewall can handle VOIP and video conferencing. Our WAN will be a 100 mbps fiber connection.
I saw the Gartner report that has Palo Alto as the best out there so I got some pricing. For the price of a PA500 I can get a SonicWall 3600 that has a lot more throughput. My main question is about the security difference.
Am I more vulnerable to an attack/data breach with the SonicWall?
Is the extra price for the lesser speed worth it?
I'm having a difficult time finding anything that rates the vulnerability of firewalls. Most analysis just talks about the bells & whistles. I have no complaints with the SonicWalls, but I don't want to be exposed to attacks.
