CompTIA Security+ SY0-701 Practice Question

Using encryption for data in transit effectively acts as a compensating control when inherent security cannot be assured through direct methods—for instance, when secure physical connections are infeasible. Encryption compensates for the insecure nature of public networks by ensuring confidentiality and integrity of the data as it moves across these networks. Although not mentioned by name, a common example of this in practice is a Virtual Private Network (VPN), which establishes an encrypted connection for data transmission, compensating for the public network's lack of built-in secure communication channels.
