What method does ZTunnel 2.0 primarily use?

ZTunnel 2.0 primarily uses Datagram Transport Layer Security (DTLS) as its primary method for secure communications, allowing for faster, more efficient data transmission without the overhead associated with Transmission Control Protocol (TCP). DTLS is particularly suited for environments that require low latency and can benefit from the connectionless nature of User Datagram Protocol (UDP).

Additionally, the fallback to Transport Layer Security (TLS) provides a robust backup method for securing the connection in case DTLS cannot be utilized, ensuring that data remains secure even under less optimal conditions. This combination allows ZTunnel 2.0 to deliver efficient performance while maintaining strict security protocols, making it highly effective for cloud-based applications and services.
