Why 8e6 is the Best - Filtering technologies are divided into two types: Pass-through (server plug-in based) and Pass-by (standalone-based). Many networks operate in a pass-through environment which creates bottlenecks in data flow. Filtering solutions placed within a pass-through environment create additional speed bumps and even a choke point if network traffic exceeds certain capacity levels. Our Pass-by solutions are placed outside the flow of network traffic: they "watch" rather than "stop and check" Web site requests. The result: no slowdown, even in heavy traffic situations. Most importantly, the Pass-by solutions do not create a point of failure.
