Harding uses a product from Secure Computing called Smart Filter to filter web content. All web access on campus whether through the campus network or the guest network is filtered.
Although Harding chooses the categories to allow, Secure Computing provides the categorization of sites. If you encounter a site that is blocked and you feel it should not be, there is a link on the page to request a site change request. Secure Computing will evaluate that request and determine whether to change the categorization.
