What type of encryption does Sophos use to protect sensitive data in transit?

Sophos employs both symmetric and asymmetric encryption to protect sensitive data in transit. This dual approach enhances security by leveraging the strengths of both types of encryption methods.

Asymmetric encryption, often used in public key infrastructures, facilitates secure key exchange. This means that sensitive data can be transmitted securely without the need for both parties to share a secret key ahead of time. Instead, one party can encrypt data using the recipient's public key, ensuring that only the intended recipient can decrypt it with their private key.

On the other hand, symmetric encryption provides efficiency for the actual data transfer once a secure connection is established. It allows data to be encrypted and decrypted rapidly using the same key, making it ideal for protecting the bulk of the data being transmitted.

By employing both encryption methods, Sophos not only secures the transmission of sensitive data but also ensures that the initial key exchange is conducted securely, creating a robust framework for data protection during transit. This combined strategy helps mitigate various types of attacks and enhances overall security resilience.
