How it works

URL Lock prevents users from navigating to web sites except for those that are allowed through one or more administrator-defined rules, which are written as Perl-compatible regular expressions. Users can either exist either on the local computer or across an ActiveDirectory network.

By operating as a browser helper object, the IE URL Lock restricts which locations a user can navigate to within Windows Explorer and Internet Explorer windows. Active IEURLLock instances automatically detect changes to their registry values and will reload their configurations at their next navigation events, making real-time configuration adjustments on a local PC possible.

The Mozilla Firefox version of URL Lock exists in the source code repository, but has not yet been released. It will be released at some point in the future.
