Hybrid Cloud Key Management & External Key Store (XKS) Integration

Bridging on-premise hardware security modules with AWS KMS XKS, Google Cloud EKM, and Azure Key Vault Managed HSM.

External Key Store (XKS) Gateway Implementation

ApiHSM acts as an authoritative AWS KMS External Key Store proxy, signing and decrypting cloud data using keys permanently stored within on-premise FIPS 140-3 Level 4 hardware enclaves.

Automatic Failover & Circuit Breaking

Configurable circuit breakers automatically route critical cryptographic workloads to secondary physical HSM nodes during maintenance windows with zero API downtime.

Hold-Your-Own-Key (HYOK): Enforcing that cloud providers never hold plain-text master encryption keys.
External Key Store (XKS): Implementing AWS XKS specifications with sub-25ms authenticated payload decryption.
Multi-Cloud Synchronization: Securely mirroring wrapped key metadata across AWS, GCP, and Azure environments.
Compliance Sovereignty: Retaining cryptographic control under GDPR, HIPAA, and national digital sovereignty mandates.
