We run a very highly demanded web and application servers in a server farm. We're shopping around for a solid firewall solution. Our vendors have made two recommendations which are PIX 535 and NetScreen ISG2000. I wanted to know what you folks think is a better fit for our enviornment. Please be clear in your recommendation and provide as much reference as possible.
- Our enviornment receives about 250,000 concurrent sessions.
- Latency is not an option. The response must be instantaneous.
- Load balanced and fully redundant firewall is a must.
- Site to Site VPN termination needs to be terminated on the firewall itself. There are currently about 25 VPN tunnels (site to site, no user tunnels).
Your input is appreciated.
