Protection the Canadian way
CIRA Canadian Shield protects you from malicious links and websites that can steal your data, install malware or trick you into scams; all from Canadian servers that keep your data in the Great White North.
Constantly stay one step ahead
Using threat feeds from both Canada and around the world, Canadian Shield protects you from threats wherever they originate. Advanced machine learning often detects new threats before they even come online.
Feel at ease with full family protection
CIRA Canadian Shield allows you and your family to safely learn, play and search online by blocking adult content from your network.
Free, without a catch
Unlike other products where free is the price for selling your personal data to advertisers, CIRA is a national not-for-profit that will never sell your data or use it to show you ads. Free is just free.
Cybersecurity built for Canadians, by Canadians
This free, easy-to-use security tool is available as a mobile app or browser extension, giving you protection across all your devices.
Once downloaded on your preferred device, accept the VPN access and choose between two levels for the highest protection:
- Protected: offers security against malware, phishing, botnet and scams
- Family: offers the same security to your household as the Protected level and blocks sexual content
Accessible and easily usable for more Canadians
Protect your web experience with the Canadian Shield browser extension. This plugin for Canadian internet users provides visual cues to indicate whether a site is potentially harmful or not. When the extension icon is green, you can browse safely; red will restrict access and present the user with a block page.
Plus, benefit from additional security by setting up PIN protection that helps everyone safely (and discreetly) navigate the internet.
