TCP (Transmission Control Protocol) provides reliable communications between two hosts, ensuring accurate and complete data reconstruction at the destination. It transfers ordered data streams from the source and is more resource-intensive than UDP due to its reliability features. In contrast, UDP (User Datagram Protocol) is an unreliable protocol that transmits data quickly but cannot guarantee delivery or accuracy. The choice of TCP or UDP depends on priorities such as data integrity, latency, performance, and the number of destinations receiving the data. While TCP guarantees complete delivery and accurate reconstruction of original data, UDP benefits applications requiring quick data transfer even if accuracy suffers, making it suitable for real-time applications like audio and video streaming. However, both protocols can increase vulnerability to cyberattacks due to their fundamental lack of security features in the Internet Protocol suite. Twingate's approach to Zero Trust Security supports both TCP and UDP, providing a modern approach to remote access and security with minimal overhead.
