Abstract

NetScreen Technologies, Inc. commissioned The Tolly Group to evaluate the performance of its NetScreen-5, an Internet security appliance integrating firewall and virtual private networking (VPN) in a SOHO environment. NetScreen requested that The Tolly Group evaluate the NetScreen-5 along with the following Internet appliances: a SonicWALL, Inc. SOHO/50 and a WatchGuard Technologies, Inc. SOHO. The Tolly Group conducted tests of devices as IPSec tunnels for application and zero-loss throughput. Tolly engineers also tested each device as a firewall and measured the zero-loss throughput when using UDP packets. For zero-loss performance tests, The Tolly Group measured steady-state throughput at 0.001%, the same metric The Tolly Group uses to test Layer 2 and Layer 3 networking devices. Testing was performed in July through November, 2000.
