What is SSL / TLS?

Definition: SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols that encrypt the connection between a browser or app and a server. TLS is the current version. SSL is outdated, though the name is still widely used.

How it works:

  • The server presents a certificate issued by a certificate authority.
  • The browser checks the certificate and agrees encryption keys with the server (the TLS handshake).
  • All data then travels encrypted, shown as HTTPS in the address bar.

Where it is used in iGaming: logins, registration, payments, KYC document uploads, API connections with game providers and PSPs.

Best practice: TLS 1.2 or 1.3 only, automatic certificate renewal and monitoring of certificate expiry dates across all brand domains.
