Post-Quantum Cryptography: The Clock Is Already Ticking
Quantum computing is no longer a laboratory experiment. It is a national priority, a venture capital magnet, and a strategic competition among global powers.
While many CIOs are watching quantum for future opportunity, far fewer are preparing for its present risk.
The issue is not when quantum arrives.
The issue is whether your data will remain secure when it does.
The Strategic Risk Organizations Are Underestimating
Today’s encryption standards — including RSA and elliptic curve cryptography (ECC) — protect nearly every critical digital interaction:
Financial transactions
Healthcare records
M&A data rooms
Intellectual property
Government communications
A sufficiently powerful quantum computer running Shor’s algorithm will be able to break these widely deployed cryptographic systems.
This creates a very real threat: “harvest now, decrypt later.”
Adversaries can capture encrypted data today and simply wait until quantum capability matures. If your organization holds data with a 10–20 year sensitivity window, exposure may already exist.
This is not a future scenario.
It is a strategic risk unfolding in real time.
What Post-Quantum Cryptography Actually Means
Post-Quantum Cryptography (PQC) is not quantum encryption.
It is the transition from today’s vulnerable cryptographic systems to new mathematical algorithms designed to withstand quantum attacks while operating on classical infrastructure.
The National Institute of Standards and Technology (NIST) has already standardized initial PQC algorithms. The migration has begun.
The only question is whether organizations will approach it proactively — or reactively.
Why “Wait and See” Is a High-Risk Strategy
Enterprise technology transitions do not happen quickly. Consider the dependencies involved:
TLS certificate lifecycles
Hardware security modules
Embedded devices
Third-party integrations
Regulatory validation cycles
This is not a software patch. It is a cryptographic transformation embedded across infrastructure, applications, and partner ecosystems.
If organizations wait until quantum capability reaches operational scale, the timeline to remediate will exceed the window available.
Preparation must begin before disruption.
What CIOs Should Be Doing Now
The era of vendor-led decisions is ending. Leaders want objective, architecture-first sourcing that aligns technology choices to business outcomes.
1. Build a Cryptographic Inventory
You cannot secure what you cannot see.
Where are RSA and ECC deployed?
Which systems rely on long-lived certificates?
Which vendors control or embed your cryptographic implementations?
Without visibility, strategy is impossible.
2. Identify Long-Sensitivity Data
Not all data requires immediate quantum resilience.
Focus first on information that must remain confidential for a decade or more:
Client financial records
Healthcare data
Trade secrets
Government contracts
These assets should define your PQC prioritization roadmap.
3. Assess Vendor Readiness
Engage partners directly:
What is your PQC migration roadmap?
Are you testing hybrid cryptographic certificates?
When will your platforms support NIST-approved algorithms?
Silence or ambiguity is itself a risk signal.
4. Develop a Multi-Year Migration Plan
PQC transition requires:
Executive sponsorship
Governance alignment
Budget planning
Risk-based sequencing
Quantum resilience must move from an innovation discussion to a board-level risk management priority.
The Board-Level Perspective
Preparing for post-quantum cryptography is comparable to reinforcing infrastructure before hurricane season.
Organizations do not wait for landfall. They invest in structural resilience well in advance because rebuilding after impact is exponentially more expensive.
Quantum risk is slow-moving — until it accelerates.
Strategic leaders prepare before inflection points.
