know of any good third party proxy services?

[vi edit]

Sort of off topic, but the software forum is slow moving. I'm looking for a company that provides proxy services and internet filtering. I've got a bunch of remote locations on DSL lines and trying to administrate local policies is a pain in the rear. I'm looking for a proxy service that will allow me to point my browsers (or even the DSL routers) to the proxy server to filter out websites that they shouldn't be visiting. A generic access (or non-access list) would work, but one that allows some sort of customization would be even better.

I know we've got quite a few admins lurking around here, so I thought I'd ask you guys.

Thanks!
