N2H2 Web Proxy/Filter appliance

[mark () NS1 LOONEY COM (Mark)]

Has anyone ever heard of a company by the name of N2H2 (www.n2h2.com),
providers of a web proxy/filter appliance, suitable for education and
state requirements for content filtering?

Arguments about the issues surrounding censorship aside, especially since
we are an educational institution and have no choice, has anyone heard of
exploits against their proxy/filter appliance, or even know what kinds of
services it is running?

The PHB is doing typical PHB things and dealing only with salespeople, and
is going out on his own on this, so I really know nothing about it.  Any
help would be greatly appreciated!

thanks
