For the duration of my career in IT Security (16 years+ now), I have been able to work with and test a large number of security products that attempt to secure users and businesses from the Web. Back in 1998, the Web was just emerging as a platform to do business on. The biggest risk organizations faced was filling up their pipe with traffic, while caching proxy solutions such as open-source Squid technology had emerged to optimize bandwidth usage. However, caching was just the tip of the iceberg in terms of new risks.
