QxVault
Overview
QxVault is a secrets management appliance that integrates open-source secrets management tooling with Crypto4A’s quantum-safe hardware security module. It provides secure storage and lifecycle management for API keys, credentials, configuration data, and other digital secrets, with hardware-backed protection that eliminates the complexity of external HSM integrations.
Unsung implements QxVault for UK customers that require hardware-protected secrets management with quantum-safe assurance, particularly in environments where secrets currently rely on software-only protection or where regulatory requirements mandate hardware key storage.
The Challenge
Managing secrets — API keys, database credentials, service account passwords, TLS private keys, and configuration tokens — is a growing operational and security challenge. Many organisations store secrets in configuration files, environment variables, or software-based vaults that lack hardware-backed key protection. As regulatory and compliance frameworks increasingly require hardware protection for sensitive cryptographic material, organisations need a secrets management approach that meets these standards without adding excessive integration complexity.
Traditional solutions involve deploying a software secrets vault alongside a separate network-attached HSM, creating integration overhead and operational complexity. Organisations need a simpler path to hardware-protected secrets management that also prepares them for post-quantum cryptographic requirements.
What It Does
QxVault addresses this by integrating the secrets management application directly with the HSM in a single appliance. Secrets are protected by the quantum-safe HSM without requiring external HSM connectivity or complex integration work. The platform provides lifecycle management for secrets including rotation, access control, and audit logging.
Built on Crypto4A’s QASM architecture, QxVault supports both classical and post-quantum cryptographic algorithms, providing crypto-agility as standards evolve. The appliance is designed for security, sovereignty, and scalability, enabling organisations to maintain full ownership and control of their secrets infrastructure without reliance on external cloud services.
How Unsung Helps
Unsung helps clients assess their secrets management requirements, evaluate whether hardware-backed protection is appropriate for their environment, and implement QxVault as part of a broader cryptographic infrastructure strategy. Our Hardware Security Modules service provides guidance on HSM-integrated secrets management alongside PKI and key management deployments.
