Liminal HSM Vaults combines the proven trust of Securosys Primus HSMs - FIPS 140-2 Level 3 certified (FIPS 140-3 Level 3 in process) - with Liminal's MPC-based authorization to help institutions secure digital asset operations with greater control and confidence.
At its core, the solution extends the hardware-rooted protection of Securosys HSMs into distributed digital asset workflows, enabling institutions to apply familiar security foundations to a new generation of financial infrastructure.
Banks do not abandon proven security infrastructure when they expand into new asset classes ─ they extend it. For digital assets, that means anchoring operations in the same hardware-rooted trust that has protected critical financial systems for decades: the Hardware Security Module (HSM).
The global HSM market is projected to grow at a compound annual growth rate of 14.6 percent through 2030, reaching an estimated $3.4 billion, with financial services driving the majority of that demand. As regulated institutions accelerate digital asset adoption, the role of the HSM is evolving from a backend safeguard to a critical enabler of compliant, institutional-scale custody infrastructure.
Through our partnership with Liminal Custody, we are helping bring that trusted security model into a new era. With Liminal HSM Vaults, Securosys and Liminal combine the proven security of Securosys HSMs with Liminal's MPC-based authorization framework to support institutional digital asset custody and transaction workflows. The result is a modern security architecture that helps banks and enterprises operate with stronger governance, resilience, and control.
Institutions entering digital assets are not willing to compromise on the standards they have long relied on in traditional finance. They need infrastructure that is credible, hardened, and familiar. HSMs already meet that standard. What is changing is the use case.
By anchoring Liminal HSM Vaults in Securosys HSM technology, the solution gives institutions a trusted hardware foundation for digital asset operations. Combined with Liminal's distributed authorization model, it enables advanced workflows involving multiple devices, multiple stakeholders, and policy-based approvals.
Robert Rogenmoser, CEO of Securosys, explains that the role of the HSM is evolving beyond traditional key storage. For banks entering digital assets, the requirement is no longer simply secure key storage but the ability to carry proven cryptographic trust into more dynamic, policy-driven environments where governance and authorization workflows must scale securely.
The system generates cryptographic proofs from multiple approval sources, enabling the HSM to verify that each authorization is valid, correctly issued, and aligned with policy before sensitive operations proceed.
"Digital asset workflows are inherently more distributed than traditional systems, but institutions still need the same level of control and assurance. By combining Securosys' trusted HSM infrastructure with Liminal's MPC-based authorization, we can help banks build security models that are both modern in design and familiar in principle."
