What is QNu QShield 2.0?

Much of today's online security relies on public-key encryption, whose underlying maths could be solved by a sufficiently powerful quantum computer. Researchers therefore work on post-quantum cryptography, meaning algorithms believed to resist such machines, and switching over takes a long time. QShield 2.0 is a platform from QNu Labs that the maker describes as providing discovery, risk qualification and crypto agility (the ability to swap cryptographic methods easily) to help organisations transition to quantum safety. The maker says it is the foundation for its own National Cryptographic Assessment and Assurance Framework (NCAAF), which it says assesses, assures and evolves a nation's cryptographic posture. QNu Labs announced the launch of QShield 2.0 in a release dated 19 September 2026.
