About Chris Basener
Chris is an Information Security Management professional with over 20 years of experience in consulting and project leadership. He specializes in helping Boards, C-Suites, and SMBs align cybersecurity strategy with business objectives — mitigating enterprise, legal, and reputational risk while driving profitability.
His expertise spans GRC, enterprise risk assessment, and building risk-aware cultures through targeted training and long-term maturity programs. Recently, Chris expanded his focus to quantum-safe security, completing MIT xPRO’s “Quantum Computing: Strategy and Impact” and earning QSECDEF’s “Introduction to Quantum Cyber Security” certification, as well as ISACA’s AAISM credential.
A former Director of Security for PMINYC, Chris combines strategic insight with hands-on execution. Outside work, he enjoys family time, reading, lacrosse, and volunteering as a first responder and ocean rescue lifeguard.
Full Article
Chris reframes post-quantum cryptography (PQC) not as a cryptographic curiosity, but as a governance and enterprise resilience issue.
Why PQC Matters Now
Most organisations acknowledge the need to prepare for PQC, yet policies, roadmaps, and execution are frequently absent. Chris, a leading voice in Governance, Risk, and Compliance (GRC), argues that the core problem is not mathematics but governance: a looming control and accountability gap created by quantum disruption.
What PQC Is
PQC is the next generation of cryptography designed to remain secure against both classical and known quantum attacks. This is not speculative. It is a documented and quantifiable risk that should be incorporated into current enterprise risk management.
The GRC Landscape
Regulatory and standards activity is accelerating worldwide.
United States
NIST Cybersecurity Framework
NIST SP 800-53
Quantum Computing Cybersecurity Preparedness Act
National Security Memorandum 10
CISA PQC initiative
IETF standardisation work
Europe
ETSI
ENISA
GDPR - while not prescribing algorithms, it requires effective safeguarding of personal data, implying PQC readiness
Comparable initiatives are under way in the UK, Canada, Australia, Singapore, China, and others.
Roadmaps and Architecture
No roadmap means no readiness. Hybrid models - in which classical and post-quantum algorithms operate side by side - are already practical. Waiting for a perfect, static standard is a risk, not a strategy.
Enterprise Impact
A PQC programme affects almost every function:
Information security
Cryptographic governance
Lifecycle management
Data classification
Third-party risk
Change and configuration management
Internal and external audit
PQC is not a cure for weak access control or poor segmentation, but neglecting it invites long-term, hard-to-detect compromise.
Risk Is Present Tense
Adversaries can harvest encrypted data today and decrypt it later. If data has a multi-year retention value, it is already at risk. Mosca’s theorem is a useful test: if data lifespan plus migration time exceeds the expected time to cryptographically relevant quantum computers, you face material risk.
Standards, Compliance, and Agility
Standards such as FIPS 203-205, PCI DSS, and ISO 27001 are beginning to address PQC. Expect PQC readiness to become a compliance baseline. A cryptographic bill of materials (CBOM) - a live inventory of all cryptographic assets - is essential. Manual inventories are brittle and quickly obsolete. Automated, near real-time CBOMs are the practical minimum.
Delivery Model
Traditional delivery methods struggle with PQC transitions. Programmes must span legacy estates, cloud platforms, and multiple jurisdictions. Chris proposes a tailored model for cryptographic overhaul that prioritises dependency mapping, agility, and staged risk reduction.
Assurance and Validation
Do not rely solely on vendor claims of PQC safety. Independent validation is required. Begin penetration testing now to reflect current collection threats. Insurers and lenders are still maturing their PQC clauses, so present clear risk-treatment plans and avoid overconfidence in any single algorithm or supplier.
Practical Principles
Design for cryptographic agility - systems must support timely algorithm and parameter swaps
Deploy hybrid cryptography where feasible - classical and PQC in tandem
Use defence in depth - do not rely on cryptography alone
Conclusion
Perfect certainty will not arrive, but real risk is already here. The quantum timeline is advancing, regardless of readiness. Act now, refine as standards and implementations evolve.
