Good Replacement for iPrism Device

We currently use an appliance from Edgewave called iPrism for our web filtering. It's a nice device and does pretty much what it's supposed to do. However, I am looking for a more full featured web protection device/service that will do basic URL filtering, evaluate web sites for malware and perhaps even do some bonnet filtering in or out of our network. We would prefer something in the cloud -although not opposed to another appliance - and something that would allow us to also protect remote users on laptops when they surf without having to force them to connect to our network with a VPN.

Please I only want responses from experts who have actually used the devices/services that you think are good replacements for this. Don't point me to a web site or white paper on something you have no experience on.
Thanx...
