â„šī¸ About SSL Certificates

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

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