Which key management option typically needs to be on-premises and delivers the keys to the...

The Hybrid key management option typically requires key management infrastructure to remain on-premises while securely delivering cryptographic keys to the cloud through a dedicated and protected connection. Managing Cloud guidance explains that hybrid key management models are designed for organizations that require maximum control over encryption keys while still leveraging cloud-based storage and processing.

In this model, encryption keys are generated, stored, and managed within the organization’s own secure environment, reducing the risk of unauthorized access by external entities. Keys are provided to cloud services only when needed and often through secure channels such as private network connections. This approach supports strict compliance, regulatory, and data sovereignty requirements.

Other options do not meet this requirement. A hardware security appliance may be used on-premises but does not inherently define a hybrid cloud delivery model. Virtual appliances are typically cloud-resident, and cloud provider services manage keys entirely within the provider’s infrastructure. Therefore, the hybrid option best aligns with on-premises key control combined with secure cloud integration.
