My work has sent me on a mission to find some Internet filtering SW. It must be easy to set up and work with on the admin side. We need something that isn't TOO good that you could let your 2 year old online all day and have no worries. It should be hilghy configurable in that way... ...So we could set it like that or back off a little. We want to be able to set what "flys" and what shouldn't be getting through.

Does this exsist?

Please let me know of some great products.

Thank you.

EDIT: User MUST be able to check web based mail.
