Basic firewall functionality: Check Point's maturity shows through
Enterprise firewalls must have policies to control traffic, ability to create site-to-site VPNs using standards-based IPsec, translate addresses and port numbers (NAT) when needed, and apply basic bandwidth management to traffic. They must also support features such as high availability (active/passive or active/active), virtual LANs, Ethernet link aggregation, and global management systems.

Check Point takes best approach to URL filtering
URL filtering has become a "checkbox" feature on most Unified Threat Management firewalls, and no wonder: it doesn't require a lot of imagination to do it right, and it's hard to really differentiate yourself or do a bad job of it.

Next-gen firewalls: Off to a good start
When we tested four next-gen firewalls strictly on performance, we found that the products could forward packets at impressive rates, but throughput dropped when advanced security features were turned on. We now dive deep into application identification and control - the defining features of next-gen firewalls - to find out what works and what doesn't.

Scaling Up With SonicWALL's Supermassive
SonicWALL's initial response to results of our SSL decryption tests was "you've got to be kidding - we go way faster than that." Indeed, the vendor's internal tests showed the Supermassive decrypting SSL traffic at rates well into the gigabit range, compared with less than 100 Mbps in some of our tests.

How we tested the next-generation firewalls
We assessed performance using three sets of tests, covering forwarding rates with mixed HTTP content; rates with static HTTP content, and TCP connection behavior. Two pairs of Spirent Avalanche 3100 GT traffic generator/analyzers, each equipped with two 10G Ethernet interfaces, served as the primary test tool. We connected all devices using an Arista Networks 7124S 10-gigabit Ethernet top-of-rack switch.
