I recently published an article on quantum exposure, focusing on why data discipline is the critical first step toward true security readiness. Quantum computing is often framed as a distant disruption, but its impact on data security is already unfolding. Adversaries are adopting “harvest now, decrypt later” strategies, collecting encrypted data today with the expectation that future quantum capabilities will break it. That reality shifts the focus from future cryptographic upgrades to present-day data discipline.
In this article, I explore why quantum readiness starts with understanding your data—where it resides, how it moves, who can access it, and how long it retains value. Organizations that reduce unnecessary data exposure, enforce strong access controls, and align security with business priorities are better positioned to withstand both current and emerging threats.
Preparing for quantum isn’t just about new algorithms. It’s about building a foundation of visibility, governance, and control that strengthens security now while reducing long-term risk.
