ℹ️ About SSL Certificates

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

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