The PQC Transition: Why Planning Starts Now

The encryption organizations rely on today was not designed to withstand the capabilities of future quantum computers. As quantum computing advances, the transition to post-quantum cryptography (PQC) is becoming a cybersecurity and modernization priority.

In a new episode of Tech in Translation, Iron Bow’s Keith Stacy, Managing Director of Networking, and Eugene McCall, Vice President of Strategy and Architecture, break down what PQC means, why planning needs to begin now and how organizations can approach the transition in a practical, risk-based way.

The Threat Is in the Future. The Risk Is Already Here.

Today’s encryption remains effective against current threats. The challenge is that sensitive information being intercepted today could potentially be stored and decrypted once sufficiently capable quantum computing becomes available, a strategy known as “harvest now, decrypt later.”

That makes PQC more than a future technology issue. Organizations need to consider how long their information must remain protected. National security data is an obvious concern, but the same principle applies to personally identifiable information, healthcare records, intellectual property and other long-lived sensitive data.

Critical infrastructure raises the stakes further. Utilities, transportation, telecommunications and other operational environments must consider not only the confidentiality of their data, but the potential impact of compromised systems and controls.

Start With What You Have

For organizations wondering where to begin, Stacy and McCall repeatedly return to one fundamental step: understand your current cryptographic environment.

That means identifying where cryptography is being used, determining which assets and information carry the greatest risk, and evaluating how quickly systems can realistically be upgraded or replaced.

The goal isn't to replace everything immediately. Instead, organizations can use inventory, risk, budget, lifecycle and regulatory considerations to build a phased roadmap for migration.

Make PQC Part of Modernization

PQC planning shouldn’t happen in isolation from broader IT strategy. Organizations making infrastructure investments today should consider whether those investments can support their future cryptographic requirements.

That includes planning for crypto agility - the ability to adapt cryptographic technologies as standards and threats evolve. By incorporating PQC readiness into existing lifecycle and modernization initiatives, organizations may be able to reduce the need for disruptive emergency upgrades later.

There Is No PQC “Easy Button”

One of the episode’s most important takeaways is that becoming quantum-ready isn't about buying a single product. Standards continue to evolve, vendor capabilities are developing at different speeds, and not every part of today’s infrastructure has a PQC-ready replacement available.

That makes planning, and the ability to connect technology roadmaps with organizational requirements, essential.

As McCall explains, the first step is understanding where you are today and then aligning technology, regulatory requirements and modernization timelines into a practical roadmap.
