I am in the process of researching options for an Enterprise level Web Content Filtering Solution for a small University. We are currently using iPrism, by St. Bernard, but have decided that it might be time to switch. We are using a Netscreen 50 firewall and would like something that will work well with that. Additonally, I would prefer an applicane-type device, rather than another Windows or Linux server to constantly patch and update. If anyone with experience with these solutions could give their input as to the best solution, it would be greatly appreciated. Please also tell me if the prioduct is a available through a one-time fee, or if it is a subscription based service. Also, the availability of a demo would be good to know about as well. Thank you.
