DNS Content Filter

The LucidView DNS Filter requires no hardware, one simply needs to redirect your organisation to our Cloud Based DNS filtering system.  This solution categorises all browsing into the various categories listed in the section below.  This allows you to block specific categories from being browsed, you can also create any number of profiles with different browsing rules.  For example; students would require a stricter block list than teachers.

Our database is vast and our A.I. crawler is constantly working at adding new sites. New sites are analysed and added to the database with the appropriate category within 30 minutes.

 

Set-Up

Our DNS Content filter is easy to set-up. For organisations with a fixed IP address you simply need to redirect to one of our DNS servers. We have a number of these across the globe.

If your organisation does not have a fixed IP then you need to set-up an l2tp  VPN to our Cloud DNS filter, and route the DNS traffic over that VPN.

Effectiveness

DNS filtering will effectively stop any users who are trying to browse websites by domain name i.e. www.website.com that are blocked.
