âšī¸ About SSL Certificates
SSL (Secure Sockets Layer) certificates encrypt data between your browser and d-nb.info's server. A valid SSL certificate ensures that your connection is private and that you're communicating with the real D-nb website.
Websites without valid SSL certificates may show browser warnings and are penalized in search engine rankings.
