Protects you from known malware and phishing. This browser extension tells you which links inside Gmail are safe, dangerous and unknown. If a link is “unknown”, you should proceed with caution. The URL reputation system built into the software tells you when sign in pages and websites are verified as safe.

MetaCert is the only software that can protect you from new dangerous links and websites that evade other security companies that haven’t had time to validate them yet.

Millions of new domains are registered by cybercriminals every year. It’s mathematically impossible for any security company in the world to protect you from them all. That’s why we decided to do things different at MetaCert.

1 minute to install / no setup.


  • Red Warning = Danger
  • Green Shield = Verified
  • Grey Shield = Caution

Whenever you open a link, this extension will immediately check it against the MetaCert authentication system. Dangerous links/websites are immediately blocked before harm can be done. And authenticated websites display the MetaCert green shield.
