DNS Filtering

What It Is

The Domain Name System (DNS) is what allows users to navigate the internet through URLs, IP addresses and domain names. It is central to all internet operations, and the National Security Agency (NSA) and Cybersecurity and Infrastructure Security Agency (CISA) have emphasized the importance of its security. Our preventive DNS filtering powered by machine learning blocks access to known malicious websites and IP addresses.
Why It’s Important

DNS filtering keeps your users from inadvertently accessing harmful content and helps mitigate the risks associated with malware infections and other online threats.
Defense in Depth Contribution

A strong DNS filter adds a strong layer of protection by controlling and securing web traffic, ensuring that only safe and verified content reaches your network and devices.

How It Works

Phishing, Malware and Botnet Protection—New domains are the biggest threats when it comes to phishing attacks. These can be prevented by filtering out malicious websites that have never been seen before. DNS security also blocks domains hosting malware and prevents “callbacks” from malware to host servers. Similarly, it prevents botnets from accessing devices that lead to various cyberattacks.
Real-time Detection—AI-powered protections categorize websites in real time to spot threats and alert clients to them faster.
Content Filtering—Content filtering blocks unwanted web content and allows users to be able to visit appropriate or favorable content. Machine learning conducts this filtering at the DNS level.
DNS Encryption—Encrypting DNS traffic allows us to protect DNS requests while they are in transit and prevent DNS poisoning attacks. DNS poisoning or spoofing is done when an attacker intercepts a DNS request and sends a fabricated (poisoned) response to the client.
Network Deployment—The DNS filter can be configured directly to your network via your router, Dynamic Host Configuration Protocol (DHCP) and more.
