How DNS and DNS filtering works

DNS is effectively an internet phone book. When you point your browser to google.co.uk (a URL that makes sense to humans), a DNS request is made to find out what IP address that refers to (an internet address that makes sense to computers). DNS records effectively pair willing web surfers with the sites they seek.

All website visits must go through DNS. This makes it a great place for network administrators to supervise end user web access, blocking risky or unsavoury websites and permitting access to work-related, professional resources.

Using DNS Filter, your administrators can set organisation-wide access permissions in a matter of minutes.

Why you need to stay in control

Cyber security threats are becoming increasingly pervasive and dangerous. Hackers know that cyber security budgets are often stretched, so they’re constantly on the lookout for softer, under-defended targets. Organisations of all kinds – from micro-businesses to multinationals – need to implement company-wide cyber security protection for both office-based workers and those on the road.

But in addition to cyber security, companies also need to ensure that their staff aren’t accessing unproductive online content or sites that contravene internal policies.

Why use DNS filtering?

  • icon-sophos-managed-threat

    Restricting access

    IP addresses or domain names that host restricted access can be blocked so users cannot access them.

  • stay-secure

    Staying secure

    A DNS server that is secure has a DNS resolver where malicious or restricted websites are blocked due to filtering Ip addresses or domain names.

  • stay-operational

    Staying operational

    DNS filters are off network protections. This means if you travel for work or work from home, your DNS filter protects you wherever you are if you need to access the internet.

  • manage-and-scale

    Manage and scale

    Centralised management provides easy access and visibility into search activity. This makes it easy to catch and identify security risks.

  • compatability


    DNS filtering doesn’t have to be restricted to PCs only it can be used across any device that has internet access as the filtering is on your network not the device.

  • increased-productivity

    Increased productivity

    By blocking certain domains and filtering out unproductive content you will see a decline in IT support requests and issues relating to URL’s needing to be dealt with.
