Hybrid Cryptography for a Safe Transition
Securosys HSMs support hybrid operations combining classical algorithms with PQC signatures and key exchange. This allows you to migrate step by step without breaking existing systems or interoperability.
shield-compliance-b&w
PQC-Ready HSMs and CloudHSM Services
Both Primus CyberVault HSMs and Securosys CloudHSM fully support post-quantum cryptography, enabling consistent protection across on-premises, hybrid, and cloud environments.
locket-circle-blocks-b&w
Designed for Larger Keys and Signatures
Post-quantum algorithms require larger keys and signatures. Securosys HSMs are built to handle increased key sizes efficiently while maintaining high performance and low latency.
map-circles-b&w
Balanced Performance During the Transition Phase
Our architecture optimizes bandwidth, storage, and processing to support both legacy and PQC algorithms in parallel — ensuring stability during long transition periods.
vault-b&w
Certified Root of Trust
All PQC operations are anchored in certified HSM hardware, ensuring that private keys are generated, stored, and used exclusively inside tamper-resistant devices.

Test PQC in a Controlled Environment

Post-quantum readiness starts with testing. Securosys offers dedicated CloudHSM services to evaluate PQC safely before production rollout.

Available test options

  • CloudHSM Economy (ECO): Cost-effective, pay-as-you-go PQC testing and production-ready service

  • CloudHSM Sandbox (SBX): Dedicated environment for PQC experimentation, integration testing, and migration planning

With Cloud Console, you can provision PQC-ready CloudHSM services online and get started within minutes.

Supported Post-Quantum Algorithms

Securosys PQC-ready HSMs support NIST-selected and established post-quantum algorithms, including:

  • ML-KEM, ML-DSA, SLH-DSA, HSS-LMS, XMSS

This enables hybrid deployments aligned with current standards and future-proof cryptographic strategies.

Research-Driven PQC Readiness

Securosys actively contributes to real-world PQC research. In collaboration with HSLU (Lucerne University of Applied Sciences), we evaluate PQC algorithm performance in TLS environments under realistic network conditions such as packet loss and latency.

This research focuses on both key exchange and post-quantum authentication, helping organizations make informed decisions beyond theoretical benchmarks.
