How they differ

CISO Tribune files both CryptoNext Security and QuSecure under Post-quantum cryptography, with Encryption, tokenization and key management as a second category, and both companies are privately held. CryptoNext Security is headquartered in Paris, France, and was founded in 2019, while QuSecure is headquartered in San Mateo, United States. CryptoNext Security completed a funding round totaling €13M with Quantonation, Axa Venture Partners, Auriga Cyber Ventures, and Kensho.

CryptoNext Security sells CryptoNext COMPASS to discover, inventory, and manage cryptographic assets, and COMPASS generates Cryptographic Bills of Materials (CBOMs). It also sells CryptoNext CAPTAIN for centralized cryptographic policy management, the PQC Pilot Package for evaluation, and a Quantum-Safe Library validated by NIST for ML-KEM, ML-DSA, and SLH-DSA. QuSecure sells QuProtect R3, a platform for cryptographic command and control that delivers continuous cryptographic inventory, remediation to TLS 1.3 with ML-KEM, and automated certificate rotation. QuSecure also sells QuProtect, software for protecting encrypted communications and data, and QuEverywhere, which orchestrates quantum-safe cryptography for websites and mobile applications. Both companies therefore address cryptographic inventory and policy management alongside post-quantum algorithms.

CryptoNext Security names work for NATO and a post-quantum IPsec VPN link between the Banque de France and the Bundesbank. In March 2025, CryptoNext Security received CAVP certification from NIST for all three standardized algorithms. On September 22, 2026, QuSecure announced it was named a Cool Vendor in a Gartner report on data security innovations.

In March 2025, CryptoNext Security received CAVP certification from NIST for all three standardized algorithms.

CryptoNext Security states that cryptography is the cornerstone of digital trust and is already under threat from quantum computers. CryptoNext Security says cryptography is rarely mapped. CryptoNext Security supports organisations at every stage of the migration project, from the initial assessment of the impacts of PQC to the ongoing management of cryptography through a crypto-agile approach. CryptoNext Security tools let organizations set up pilot projects to test the new algorithms against specific use cases covering latency, application compatibility, and critical dependencies.[4][5][11]

CryptoNext COMPASS is an open solution designed to discover, inventory, and manage cryptographic assets within complex environments.

CryptoNext COMPASS maps the use of cryptography across networks, protocols, and applications, including in IT and OT environments. CryptoNext COMPASS presents cryptographic assets that are typically invisible or undocumented through structured dashboards. CryptoNext COMPASS aggregates and correlates cryptographic data within a single platform. CryptoNext COMPASS connects each cryptographic asset to the criticality of the data it protects. CryptoNext COMPASS maps the dependencies between assets so that the impact of a remediation can be assessed before launching it. CryptoNext COMPASS generates Cryptographic Bills of Materials (CBOMs). CryptoNext COMPASS runs large-scale analysis with AI. CryptoNext COMPASS integrates using customizable connectors. CryptoNext Security launched COMPASS Discovery, a cryptographic discovery platform.[6][7]

CryptoNext CAPTAIN centralizes the management of cryptographic policies within the organization. CryptoNext CAPTAIN abstracts cryptographic operations from applications using CAPTAIN Provider technology. CryptoNext CAPTAIN integrates with a wide range of traditional cryptographic providers. CryptoNext CAPTAIN features native integration of the CryptoNext post-quantum library.[9]

The PQC Pilot Package is an evaluation platform designed to measure the real-world impact of post-quantum cryptography and prepare an organization for an enterprise-wide migration. The PQC Pilot Package measures effects on use cases such as latency, throughput, memory consumption, and operational load. CryptoNext Security has developed a post-quantum plug-in for Outlook that signs and encrypts messages using the Quantum-Safe Library. CryptoNext Security offers the Quantum-Safe Library, validated by NIST for the three standardized algorithms ML-KEM, ML-DSA, and SLH-DSA. CryptoNext Security describes a hybrid approach combining traditional and post-quantum cryptography that maintains compatibility with current systems.[5][10][11]

CryptoNext Security has deployed its post-quantum solutions in the banking, finance, defense, energy, aerospace, and public sectors. CryptoNext Security has worked with banks, defense contractors, and critical infrastructure operators. CryptoNext Security deployed a secure post-quantum instant messaging system for NATO and a post-quantum IPsec VPN link between the Banque de France and the Bundesbank. CryptoNext Security implemented a secure post-quantum email messaging system between the Banque de France and the Monetary Authority of Singapore (MAS).
