The Blue Coat ProxySG began life long ago as a proxy cache by CacheFlow. Recognizing the market opportunity to secure that traffic they developed more security features and pioneered the secure web gateway. Blue Coat has their own web filter product with a perpetual license (as opposed to a subscription) which can save you lots of money if you own it for a long time. Along the way, they bought an early gateway AV product, Ositis, which became ProxyAV. ProxyAv talks to ProxySG via ICAP to scan traffic for malicious content in a number of ways.

Blue Coat ProxySG is now the reference secure proxy gateway.
