Quantum computing promises to transform technology, but it also poses a serious threat to current cybersecurity systems. Many encryption methods that protect sensitive data today will become vulnerable once powerful quantum computers arrive. Cybersecurity leaders face the urgent task of preparing their organizations for this shift. This guide offers a clear, practical workflow to help you build a post-quantum roadmap that protects your data and strengthens your security postu

As quantum computing transitions from theoretical physics to engineering reality, the global cybersecurity landscape faces a systemic threat that cannot be patched overnight. While many view the "Quantum Apocalypse" (or Q-Day) as a distant concern, a sophisticated and silent strategy is already being deployed by nation-states and cybercriminal syndicates: the "Harvest Now, Decrypt Later" (HNDL) attack. The Mechanics of the Silent Theft The HNDL strategy is chillingly simple.

Encryption is the invisible bedrock of the digital age. It is the process of encoding information so that only authorized parties can access it, acting as a mathematical vault for everything from your private WhatsApp messages to global interbank transfers. However, a "silent" crisis is approaching. While today’s encryption feels unbreakable, the rapid evolution of quantum computing is creating a deadline for global security—a milestone experts call "Q-Day." The Architecture
