What transport security method does Salesforce utilize to ensure secure communication?

Salesforce utilizes Transport Layer Security (TLS) to ensure secure communication. TLS is an updated and more secure version of SSL, which many people still refer to generically when discussing secure web communications. TLS provides a robust encryption protocol that protects data integrity and privacy during transmission, making it essential for secure web applications, including Salesforce.

While SSL is still referenced in discussions about web security, it has known vulnerabilities that TLS effectively addresses, establishing itself as the industry standard for secure communications.

Secure Hypertext Transfer Protocol (HTTPS) is a concept that incorporates TLS (or its predecessor SSL) for secure communication over the internet, but it is not the direct transport layer security method. Data Encryption Standard (DES) relates to data encryption rather than transport security and is considered outdated due to its weaknesses. Thus, TLS is the most accurate choice for transport security in Salesforce communications.
