Cloud Encryption Gateway
Definition - What does Cloud Encryption Gateway mean?
It is a tool that sits between a cloud system and an in-house system, and performs encryption or tokenization of data in transit. The resulting "shielded" data can then be used safely by software-as-a-service (SaaS) applications.
Techopedia explains Cloud Encryption Gateway
In addition to encryption gateways, other strategies for data encryption include full disk encryption, where the entire operating system platform is scoured for information to be encrypted; database encryption, which can be similar to a cloud encryption gateway; and even encryption solutions, which can be run from a hypervisor in a virtual environment.
