A public DNS service with cybersecurity

CIRA Canadian Shield protects you with the same threat feed data that powers our CIRA DNS Firewall, which is used by organizations across Canada, serving over 3 million users.

We bring in dozens of threat feeds and add powerful AI from Akamai to analyze billions of DNS queries globally every single day. This detects over 100,000 new threats daily to help keep you safe online!

When we say free, we really mean it

Some companies take personal data as payment for “giving” you a free service. They use it for advertising, tracking, and reselling to others.

CIRA is a Canadian not-for-profit that has been routing and connecting Canadians to the internet for more than 20 years—without selling your data. CIRA Canadian Shield doesn’t cost you money or privacy.

Safety and privacy that doesn’t compromise speed

Our speeds are comparable to some of the biggest names in the world because our servers are exclusively in well-connected Canadian data centres.

While we may not always be the fastest, security takes time, and we think a millisecond or two is worth keeping your data private.

Three options for your DNS

  1. Private: Offering DNS resolution only
  2. Protected: Adds malware, phishing, botnet and scam protection
  3. Family: Adds pornographic content to the block list
