Cloud HSM

Cloud HSM (Hardware Security Module) is a cloud-based service that provides secure cryptographic key storage and operations using dedicated hardware appliances in the cloud. It enables organizations to generate, store, and manage encryption keys in FIPS 140-2 Level 3 validated hardware, ensuring high security for sensitive data and compliance with regulatory requirements. This service offloads cryptographic processing from applications to specialized hardware, enhancing performance and security for tasks like encryption, decryption, and digital signing.

Also known as: Cloud Hardware Security Module, CloudHSM, HSM as a Service, Managed HSM, Hardware Security Module in the Cloud

Why learn Cloud HSM?

Developers should use Cloud HSM when building applications that require stringent security for cryptographic operations, such as in finance, healthcare, or government sectors where data protection and compliance (e.g., PCI DSS, HIPAA) are critical. It is ideal for scenarios like securing SSL/TLS keys, protecting database encryption keys, or managing digital certificates, as it provides tamper-resistant hardware isolation that reduces the risk of key exposure compared to software-based solutions.
