Nutshell Quantum-Safe GmbH

Quantum computers are not yet powerful enough to break current encryption — but they are getting there. And the problem is that many of today's encrypted communications and stored data may already be collected and held by malicious actors, ready to be decrypted once quantum computing capacity makes it possible. This strategy, known as harvest now, decrypt later, transforms quantum risk from a future problem into a present one. Nutshell Quantum-Safe develops post-quantum cryptography software solutions designed to protect data and communications in the era that lies beyond the quantum computer. The transition to cryptographic algorithms resistant to quantum attacks is not straightforward: it requires specific expertise, integration with existing systems, and a deep understanding of emerging standards — such as those recently finalised by NIST in the United States. Nutshell positions itself as a technical partner for organisations that need to navigate this transition in a structured way, protecting today the critical infrastructure that will need to remain secure a decade from now. The target audience includes companies, financial institutions, critical infrastructure operators, and any organisation managing sensitive data with long time horizons. The model is built around an operational framework of support and implementation. In a regulatory landscape moving rapidly toward mandatory quantum-safe cryptography in critical sectors, Nutshell provides the technical expertise needed to stay ahead of the curve.
