Firewalls provide protection at the network perimeter, email security software prevents spam, phishing, and malware-laced emails from being delivered to inboxes, and anti-virus software will block any known malware from executing if downloaded. A DNS internet filter provides protection from malware downloads and blocks the web component of phishing attacks, and is an important extra layer to security to protect against threats that are not blocked by other security solutions.

How Does a DNS Internet Filter Work?

Every internet-enabled computer has two Domain Name System (DNS) servers that are used to find the IP addresses of websites. A request is sent to the DNS server, which will perform a series of checks to identify the IP address of the website, which will then be returned to the browser allowing a connection to the website to be made.

A DNS internet filter is inserted into this process. The request is made as normal, the lookup is performed, but then filtering controls are applied. With a DNS internet filter in place, every time an employee or guest user attempts to visit a malicious or prohibited website, a connection to the website will not be made and the user will instead be directed to a local block page that informs them the website cannot be accessed because it violates a company’s policies.

Why is a DNS Internet Filter so Important?

Malware can be delivered via email, but it is also commonly downloaded from the Internet. Malicious websites are set up to fool the unwary into disclosing sensitive information and downloading malware. Websites are also used to host exploit kits, which probe for vulnerabilities on computers and exploit them to silently download malware. Anti-virus software, spam filters, and other cybersecurity solutions will not prevent users from visiting those websites.

A DNS filter provides an additional layer of protection by blocking access to those websites and also allows businesses to exercise control over the types of content their employees can access.

A DNS filter uses databases of known malicious IP addresses and illegal websites, so any attempts to visit those sites will be blocked. DNS filters also categorize websites based on their content and filtering controls can be applied to block access to certain types of website. It is also possible to block access to web content based on certain keywords in the text. By controlling access to certain categories of website, businesses will be able to make productivity gains and avoid HR and legal problems.

Provides good security, saves me an hour a day, and is cost-effective

It's very easy to configure to block and greylist a lot of things that we see coming in as a vector for email attacks. So, it gives us much better security overall, as well as some time savings on the administration side.

Has the ability to easily see what was blocked, enabling users to restore emails they were expecting with the click of a button

It reduces email clutter, improving employee productivity. It does what it says it does. It reduces spam by quite a bit above and beyond the Office 365 built-in spam filter. One aspect our clients liked about SpamTitan was the ability to easily see what was blocked.
