CryptoNext Remediation

Implement the best of PQC

Post-quantum cryptography is no longer optional, it is the only one capable of withstanding quantum attacks. With CryptoNext Security’s Quantum Safe Library, adopt a state-of-the-art solution that guarantees the highest level of protection.

The New Standard in Cryptography

The Quantum-Safe Library by CryptoNext Security is the first post-quantum cryptographic library in the European Union to receive NIST validation for all three standardized algorithms.


Quantum-Safe Library

A State-of-the-Art Post-Quantum Library

With post-quantum cryptography come new challenges related to reliability, security, performance, size, and resource usage. As a result, the control and quality of cryptographic implementations—from source code to compiled binaries—have never been more critical. The Quantum-Safe Library meets this demand with an award-winning design that is fully controlled end-to-end, includes all standardized algorithms, and is portable across all types of environments.

  • Safeguard the confidentiality, authenticity, and integrity of your data and communications.
  • Protect yourself against quantum cryptanalysis attacks
  • Secure your systems against timing and side-channel attacks
  • Stay ahead of threats by integrating new standardized algorithms the day they are officially released
  • Leverage CryptoNext Security’s expertise to deploy the library within your IT infrastructure
  • Ensure the ongoing security compliance of your cryptography through our continuous security monitoring

Key Features

Use Case

Protecting Sensitive Communications with Post-Quantum Messaging

To address sovereignty and resilience challenges posed by the quantum threat, NATO partnered with CryptoNext Security to enhance an open-source messaging application. The goal was to deliver truly secure end-to-end communications—voice, video, and messaging—by adding a quantum-resistant cryptographic layer and dedicated group features. CryptoNext Security integrated its Quantum Safe Application (QSA) plugin into the messaging platform, while the organization’s technical teams conducted functional and stress testing.

Why Now Is The Time To Migrate To PQC

There is broad consensus that post-quantum cryptography has become a strategic imperative. Yet many organizations fall into the trap of “crypto-procrastination,” delaying the transition due to time constraints or perceived complexity. This inertia carries significant risks: waiting increases exposure, erodes competitiveness and jeopardizes compliance with upcoming regulatory requirements. To safeguard long-term security, it is essential to make post-quantum cryptography a top priority now.
