Which protocols does 3CX employ to ensure data security?

3CX employs TLS (Transport Layer Security) and SRTP (Secure Real-time Transport Protocol) to ensure data security. TLS is a cryptographic protocol designed to provide secure communication over a computer network. It encrypts the data being transmitted, protecting it from interception and tampering as it travels between endpoints. This is particularly important in VoIP systems, where sensitive voice data is exchanged.

SRTP, on the other hand, specifically addresses the security of real-time communications such as voice and video. It provides encryption, message authentication, and integrity, ensuring that the media streams are protected from eavesdropping and unauthorized modifications.

Together, TLS and SRTP create a robust framework for securing communications within 3CX, making them essential for maintaining confidentiality and data integrity in VoIP applications. Other protocols listed, such as FTP, HTTP, and POP3, either do not provide secure transmissions or are not commonly associated with VoIP security.
