NordLayer - Network Security

DNS Filtering service

Secure your business environment against online threats by blocklisting and blocking malicious sites.

OVERVIEW

What is DNS Filtering?

Instead of inputting a nine-digit IP address for each website, the Domain Name System (DNS) enables users to visit websites using easy-to-remember domain names, such as NordLayer.com. DNS filtering blocks malicious websites and filters out sites that contain harmful and/or inappropriate content. Managers can choose what types of content shouldn’t be accessible by employees on company-managed networks and the DNS filters will do the rest. This improves the security of company data and secures your team members from malicious activity & phishing websites.


HOW IT WORKS

How does DNS filtering work?

Normally, when trying to reach a website, your DNS server uses its own “phonebook" to look up the domain or IP address. Once found, the server enables a connection between your browser and the web server hosting the website.

With DNS filtering, the same request is subjected to a few additional filters to make sure the site is secure and access is authorized through your organization. If the site is on a blocklist or is malicious, the DNS resolver will block the request, preventing the site from loading and stopping a potential cybersecurity risk.

Frequently asked questions

Let’s say an employee receives a phishing email and clicks the malicious URL. The DNS resolving service, which makes use of DNS filtering, receives a query from the employee’s computer before it loads the webpage. The DNS resolver will then reject the request if the malicious website is listed on the company’s blocklist or is identified by ThreadBlock. This will stop the malicious website from loading and stop the phishing assault in full.

Web filtering is an umbrella term that refers to several methods for regulating online traffic. DNS filtering is just one type of web filtering, the others being URL filtering, keyword filtering, and content filtering.
