Add a Free Layer of Security, Privacy, and Performance to Your Work or Home Network

Good security involves having multiple layers of defense.  A free layer is available for you to use for work and/or your home networks, and it can be set up in less than 15 minutes!


The Domain Name System (DNS) is what the internet uses to translate domain names (i.e. to numerical IP addresses (i.e.  Your network (or device) points to a DNS server that does this translation.

Many internet providers provide very basic and insecure DNS services.  By simply changing your DNS server settings from your internet provider’s DNS servers to secure DNS servers you can add a free layer of security for your systems and increase the performance and privacy of your internet connection too.


Secure DNS servers can block known malicious domains that have risks such as:

  • Malware
  • Viruses
  • Phishing
  • Adult content (if you choose to block this)


As a recommended best practice, your internet connection should point to secure DNS servers.

Keep in Mind:

These settings block many known malicious domains, however, no solution can block 100% of all bad domains.

These settings will also automatically encrypt your connection to your DNS servers (most modern devices 3 years old or newer support this) adding even more security and privacy to your online activities.
