CryptoNext Security

Cybersecurity · Paris, France · Founded 2019

Next generation of cryptographic standards that will make IT infrastructures resilient against quantum computers MoreLess

CryptoNext Security is a startup that operates in the cybersecurity market, specifically focusing on post-quantum cryptography. Their mission is to provide ultimate post-quantum remediation, which means they aim to protect data from potential threats posed by quantum computers. Quantum computers have the ability to break public-key cryptosystems in seconds, which could lead to significant security breaches. CryptoNext Security's solution to this problem is their Quantum Safe Remediation (C-QSR) technology.

The company serves clients who are looking to transition to quantum safe systems and applications. This transition involves more than just defining new cryptographic algorithms that can resist quantum computer attacks. It requires a shift from a single standard for public-key cryptosystems to an ecosystem of standards that vary based on functions, use cases, or regulations. CryptoNext Security provides the technology and expertise needed for this transition, ensuring that it is done correctly to avoid any vulnerabilities.

CryptoNext Security's business model revolves around their suite of post-quantum software tools. These tools, which are part of the C-QSR technology, are designed to work together and are based on CryptoNext’s core library (C-QSL). The tools allow for multi-layer migration for applications, data, and infrastructure with ultimate post-quantum security and performance. The company makes money by selling these software products at various levels, including algorithms (QSL Library), protocols and crypto objects (QSC Services), development tools (C-QST Tools), and application plugins.
