Post-Quantum Cryptography is a “Board-Level Survival” Issue

We’ve spent 15 years telling ourselves that quantum computing is a “future problem,” but as a Quantum Security 25 leader and Qrypt CTO Denis Mandich makes clear, Q-Day is no longer a distant sci-fi fantasy—it’s an imminent deadline for global economic survival. From the silent gathering of “Harvest Now, Decrypt Later” data to the devastating potential for nation-states to forge code-signing keys and hijack entire government agencies, the risk isn’t just about tomorrow’s math; it’s about today’s architectural fragility. If your C-suite hasn’t prioritized a 2029 migration deadline for your most sensitive data, you aren’t just behind the curve—you are essentially operating with a wide-open back door in a world that can’t afford to lose this race.
