Quantum computing poses a growing threat to current encryption, especially in the financial sector where sensitive data must remain secure for years. Criminals can store encrypted data now and decrypt it once quantum power becomes available, risking massive breaches and costs. Preparation should start early, as migration to quantum-safe cryptography (QSC) can take years. QSC—also called post-quantum cryptography—resists both classical and quantum attacks, and can run alongside existing systems. SSH’s Tectia Quantum-Safe Edition uses a hybrid approach to secure data in transit, ensuring future-proof protection.
