ℹ️ About SSL Certificates

SSL (Secure Sockets Layer) certificates encrypt data between your browser and 1st-net.de's server. A valid SSL certificate ensures that your connection is private and that you're communicating with the real 1st-net website.

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