ℹ️ About SSL Certificates

SSL (Secure Sockets Layer) certificates encrypt data between your browser and tester.test.io's server. A valid SSL certificate ensures that your connection is private and that you're communicating with the real Tester website.

Websites without valid SSL certificates may show browser warnings and are penalized in search engine rankings.
