NxFilter is an enterprise-level web filter, and setting it up needs some network experience, and a little time. If the default site blocking isn't enough, NxFilter supports adding domains manually, or grabbing the blacklist from You get a stack of configuration options, there's even support for authenticating users via LDAP and Active Directory (as well as password and IP address), all while delivering great performance (the developer claims NxFilter can handle "several thousands of users easily"). And you're even able to assign policies based on a time range, so for example an office might have a very loose policy at lunchtime, but something much more restrictive for the rest of the day. These policies can be applied to individual network users, or groups of users. If you need more control, it's possible to create NxFilter policies which block sites by category (75 in total), or only allow access to particular site categories - or all internet access - for a certain amount of time a day. A browser-based console displays stats on web traffic, blocked domains and more, as well as logging every site you've accessed.

It's still not difficult - if you know how to configure your system to use a custom DNS server then you won't have much trouble - but you will have a little work to do.

You'll first need to install and configure the program, of course, and that can take a little effort. It's also possible to limit access by user and time, and one NxFilter installation can protect your entire network.
