Net.purum

Net.purum is a filtering application that is divided into three parts: Server, Administration and Testing. The Server part creates content filtering, with rules that are defined or depicted in the Administration center. Finally, the Testing center verifies all the settings in Net.purum. Net.purum works with MS ISA or a custom internal proxy server.

Users from local networks use a proxy server, from where the Net.purum filter is activated. Net.purum can block infected files, advertisements, use of method POST, cookies, prohibited categories of Web pages, prohibited file extensions, prohibited search terms (I.E., in search engines), specific language, users who exceed a pre-set monthly data transfer size limit, prohibited "Content-type" in an HTTP answer.

Exactly what, and how to block, can be set specifically for each user group. Rules for blocking are sorted into categories. All users are included in groups and into each group, blocked categories can be assigned.

Users can be defined by IP address or by login name. However, the login name can only be used when NTLM authorization is enabled for proxy server. Users can be imported from Active Directory.

Basic folders of categories include Nudity, Ordering, Education, Religion, Criminal Activities, Extreme, Games, Entertainment, Information, IT, Drugs, Lifestyle, Private Homepages, Job search, Finance, Transportation, Weapons, and Medicine. Each category contains certain phrases. These phrases define the categories, and could be: server addresses, rules for text censors, file extensions, search themes, etc.
