What types of encryption does Mimecast support?

Mimecast supports both TLS (Transport Layer Security) and PGP (Pretty Good Privacy) encryption as essential components of its secure email transmission and storage. TLS is utilized to secure the communication channels between email servers, ensuring that the data in transit remains confidential and protected against eavesdropping or tampering. This is crucial for protecting sensitive information as it moves across the internet.

PGP, on the other hand, is used for encrypting the actual contents of emails, providing an additional layer of security by allowing users to encrypt messages to specific recipients using a public-private key pair. This means that even if an email is intercepted, it cannot be read without the appropriate decryption key.

Together, these encryption methods enhance Mimecast's security framework, ensuring that email communications are securely transmitted and stored, safeguarding user data from unauthorized access. Other options focus solely on individual methods of encryption or state that Mimecast does not support encryption at all, which does not align with the services Mimecast offers.
