How to block websites.
If you want to block sites with objectionable material, or block a site in order to improve productivity, IM Lock is a good solution. When you deploy IM Lock is virtually impossible for the user to unblock sites, or to use a proxy website to work around the internet block. Unlike an ip block, IM Lock uses keyword blocking to prevent access to blocked sites. These articles will explain how to block internet and how to create block policies, how to block a single website, and how to block all but one website, and much more.
