TLS (Transport Layer Security) and its’ predecessor SSL (Secure Sockets Layer) and are cryptographic protocols used to secure communication over the internet.

SSL/TLS ensure that data transmitted between a user’s browser and a server is encrypted, preventing eavesdropping, tampering, and data theft. SSL has largely been replaced by TLS, which provides stronger security features.

Websites use SSL/TLS certificates to establish trust and protect sensitive information such as login credentials, payment details, and personal data during transmission.
