If you need web services, this product covers your needs.

I would rate this solution an eight out of ten. 

If you are using schedule-based policies, for example, Monday 9:00 AM to 6:00 PM in the evening, then Blue Coat is the best product to go for.

My advice is that if somebody is using the Blue Coat or Symantec solution, then only use Blue Coat products. They integrate well and you don't need to manage different solutions.

I would rate this solution eight out of ten.

My advice to someone considering this solution is to look at your longterm needs. 

I would rate this solution a three out of ten. The should include a DNS security layer to improve this solution. They should also make it easier for roaming users.
