Uncontrolled internet access is a high-risk activity for any business, regardless of size. Faced with today’s sophisticated attacks, endpoint security is no longer enough to stay safe from modern cybercrime. DNS Filter lets businesses take control of internet use within the company’s network.
What is DNS Filter?
DNS filtering is the practice of blocking access to certain sites for a specific purpose, often content-based filtering. If a site, or category of sites, has been deemed a threat, then its IP address is blocked with a DNS filter and access to it is prevented. A DNS Filtering system will always block users from malicious content. Once a website has been categorised, the filter will either display the page or block it depending on the parameters set up ahead of time by an organization. So, for example a user is trying to access Facebook during work hours at a company that has blocked the site, they will see something like this:
Block pages are usually customizable. If you encounter a company block page, you might see your company’s logo with a note that they’re the ones who are blocking you.

Why do I need DNS Filtering?
Unmanaged, uncontrolled internet usage seriously impacts security, visibility of internet use, network speed, and staff productivity.
- Security – DNS Filtering prevents users from accessing malicious sites that can administer phishing, ransomware, or cryptojacking attacks. It can stop up to 88% of internet-borne malware before it even reaches the network.
- Visibility of Internet Use – DNS Filtering gives business owners full control and visibility over websites visited and other internet activities.
- Network speed – DNS Filtering prevents access to identified sites like peer-to-peer streaming sites or social media sites that not only distracts workers during work hours, but can also sap bandwidth.
- Productivity – DNS filtering policies are set to avoid time-wasting sites like streaming and social media and other potential sources of HR pain, so business owners can take back control of their networks.
Web Filter List
Web Filter lists are customisable per organization. But from an IT perspective, there are categories that pose higher security risk than others (e.g. adult/mature content), and consume bandwidth (e.g. streaming and downloading sites). These have no place in the work environment and non-negotiable. Other filter settings will depend on an organisation’s requirements.
