Crypto4A Technologies Launches QxOS 5 to Power Future of Post-Quantum Security

Crypto4A Technologies Inc., a pioneer in quantum-safe and crypto-agile security solutions, launches QxOS 5, the latest evolution of its cryptographic OS designed to support the QxHSM, the next-gen of hardware security modules (HSM).

This major software and firmware release strengthens the foundation for post-quantum cryptography (PQC) adoption, digital sovereignty, and improved security usability.

With the introduction of QxOS 5, the company delivers 3 core advancements:

• FIPS 140-3 Level 3: This release includes the finalized module submission for FIPS 140-3 level 3 certification that includes the latest PQC algorithms, reinforcing trust for regulated industries and government agencies.
• Certified Post-Quantum Cryptographic Algorithms: QxOS 5 integrates a robust set of PQC algorithms aligned with current NIST standards, providing proactive protection against quantum computing threats.
• Enhanced Usability: Updated user interfaces, management applications, operational tools, and APIs make it easier than ever for customers to deploy and manage cryptographic workflows securely and efficiently.

“QxOS 5 is more than just a firmware and software update, it’s a critical step toward real-world readiness for post-quantum environments,” said John O’Connor, VP, product management, Crypto4A. “With our FIPS submission, certified PQC algorithms, and usability upgrades, we’re helping customers stay ahead of the curve – technically and strategically.”

Supporting PQC and Digital Sovereignty
Crypto4A’s commitment to digital sovereignty is rooted in giving customers full control over their cryptographic infrastructure. QxOS 5 embodies this principle by enabling transition to post-quantum algorithms while maintaining crypto-agility and compliance. Organizations can now future proof their digital assets with confidence and clarity.  As cyber and regulatory environments continue to evolve, this update provides the adaptability and assurance that enterprises and agencies require while also supporting strategic priorities such as cryptographic independence and long-term flexibility.

Looking Ahead
The launch of QxOS 5 sets the stage for an exciting product roadmap. Upcoming feature releases this year will introduce expanded algorithm support, advanced policy orchestration, scalable key storage, application developer kit, and richer integrations to further simplify secure operations in quantum-threatened environments.
