Quantum computers will break today’s encryption in seconds. We already have prepared systems for what comes next.   What sounds like a distant future scenario is becoming a concrete security challenge. Once powerful quantum computers are available, many of today’s cryptographic methods will no longer provide reliable protection. Passwords, keys and encrypted data that are considered secure today could become vulnerable almost instantly. This turning point is often referred to as Q‑Day.   For organizations, the decisive question is not when Q‑Day will happen.  It is whether products and systems are designed to cope with such a fundamental shift without having to be rebuilt under pressure.    In the video below, we look at why post‑quantum security cannot start on Q‑Day itself. Future‑proof cybersecurity requires quantum‑secure approaches that are modular, updateable and designed for long‑term use – allowing systems to adapt as cryptographic assumptions change.  The focus shifts from short‑term protection to building security that is meant to last.    🎬 The video takes a closer look at how cybersecurity can be prepared for the quantum age.  If post‑quantum security and long‑term cryptographic strategies play a role in your context, Claude-Pascal Stöber-Schmidt and Carsten Elvers, cybersecurity experts, are available for further exchange.
