How DNS and DNS filter 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.

Stay in control with lightweight, no-nonsense threat defence and content blocking.

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.

There is a remarkably simple solution to this conundrum: DNS Filter. Through this simple, automated, light-touch platform, you can block your team from accessing potentially dangerous, unproductive, or objectionable websites. Wherever your users are, whatever devices they use.

DNS Filter relies on over 30 worldwide data centres to provide reliable, global protection with a virtually unnoticeable effect on speed and 100% uptime.

This peace of mind can be yours from a minimal £1.95 per user, per month fee.


Malware is maliciously designed code that targets networks to gain unauthorized access. Using one of many methods like; computer viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, wiper and scareware. 

Ransomware, Malware, Cyber Attacks
Hacked Logins and passwords. Phishing attacks


Phishing are fraudulent attempts to obtain data, usually credit cards, usernames, passwords or data and information that can be used to access other more sensitive data by disguising or impersonating  someone/something in an email, text or telephone message. 

DNS Spoofing

DNS Spoofing is hackers redirecting your web traffic towards fake web servers and phishing sites. Impersonating a device, client or user to intercept and access protected data. Once they have access they can steal information, install malware to damage the system or lie in wait to use in future attacks.

Stay Vigilant

Many cyber security solutions rely on threat databases that become outdated quickly. However, DNS Filter’s AI-driven zero-day protection hunts down potentially risky domains before they become known threats, giving our users a unique cyber security advantage.

Stay Productive

When filtering out unproductive content, you may naturally see an increase in productivity - but there’s more to DNS filtering than that. By automatically blocking risky links, you’re likely to see fewer IT support requests, freeing up your time to focus on your business.

Stay Connected

Any internet-enabled device can be used to carry out a cyberattack or access unproductive sites, so why not protect them all?
