Cloud encryption gateway

Cloud encryption gateway definition

Cloud encryption gateway is a security solution that acts as an intermediary between a client and a cloud service provider to encrypt data before it leaves the client's network and enters the cloud. This ensures that data remains encrypted as it travels to and from the cloud and while it's stored in the cloud.

When data is retrieved from the cloud, the gateway decrypts it before it's used or displayed within the client's network. The gateway manages the encryption keys, ensuring they are securely stored and accessible only to authorized entities.

Cloud encryption gateway use cases

  • Data privacy and compliance. For businesses that handle sensitive information, a cloud encryption gateway helps comply with privacy laws and regulations.
  • Secure cloud storage. When using cloud storage, the gateway encrypts files before uploading them, ensuring data security.
  • Email encryption. Encrypts emails before sending them to cloud-based email services, protecting sensitive communication.
  • Hybrid cloud environments. Data moves between on-premises and cloud-based systems in a hybrid cloud environment, so encryption gateways ensure that data is encrypted in transit and at rest.
  • Multi-cloud strategies. Organizations using multiple cloud service providers can employ encryption gateways to maintain a uniform encryption strategy across different platforms, simplifying data security management.
