What role does encryption play in Zero Trust security?

Encryption is a fundamental component of Zero Trust security, primarily because it protects data integrity during transfer. In a Zero Trust model, every access request is treated as a potential threat, regardless of whether the request originates from inside or outside the network.

By encrypting data, organizations ensure that even if data is intercepted during transmission, it remains unreadable to unauthorized users. This protects the integrity of the data by preventing tampering or unauthorized access, which is crucial in maintaining trust within interactions. Additionally, encryption supports confidentiality, ensuring that sensitive information is accessible only to authorized parties.

While encryption contributes to various security aspects, its primary role in Zero Trust revolves around safeguarding data integrity and confidentiality during communication between users, devices, and applications in a dynamic environment where trust is never assumed.
