Quantum cybersecurity represents the next frontier of digital defense, encompassing the strategies, tools, and policies required to protect information and systems from attacks powered by quantum computing. This evolving discipline addresses two primary threats: the ability of a quantum computer to break current public-key encryption and the potential for quantum-based attacks like quantum sensing to disrupt systems. It moves beyond traditional models to implement quantum-resistant cryptography, leverage quantum key distribution (QKD) for ultra-secure communication, and develop new protocols for a quantum future. Cystel’s holistic IT & OT Security Solutions are designed to integrate these advanced concepts, providing a layered defense that safeguards your critical infrastructure and data assets.
