Web Filter

As of Untangle 10.0, every purchase of Web Filter includes HTTPS Inspector at no additional cost. You must run Untangle 10.0 to use HTTPS Inspector. Web Filter (and HTTPS Inspector) is also included in NG Firewall Complete, Public Sector Complete and Nonprofit Complete packages.


Web Filter enables administrators to block inappropriate web content in realtime. The dynamic URL categorization engine makes it easy to block 450M+ (that’s million!) classified websites in over 140 categories and almost 200 languages. Great for “traditional” categories like porn, gambling, social networking & more.


Web Filter was originally built to combat online security threats where rapid reaction to emerging threats was paramount. Zvelo’s Distributed Intelligence Architecture leverages the power of its wide implementation by verifying and classifying every new website and webpage that protected users browse to with algorithmic triggers and a team of 70 professionally trained multilingual web analysts. While 99.9% of users browse sites that are already classified within the 450M+ database, new sites that users find are classified and updated to the hosted database in realtime so that all customers benefit instantly.
