Cybersecurity has traditionally been reactive, responding to breaches, applying patches, and preparing for audits. But quantum computing demands a fundamentally different approach. It’s not about managing current threats; it’s about preparing today for an irreversible risk that may not materialize for years. In this case, waiting means losing.
Quantum computing doesn’t have to be fully realized to create risk. Once it reaches a critical threshold, the encryption used to protect today’s sensitive data could be rendered obsolete, exposing previously secure information. For business leaders, quantum readiness is not just a forward-thinking strategy but a critical obligation.
Key Pillars of Quantum-Ready Cybersecurity
A proactive approach to quantum risk involves both technical planning and cross-functional alignment. The steps below outline a strong foundation for building resilience.
1. Quantum Risk Assessment
Understand what’s at stake.
Start by identifying where public-key cryptography is used, such as email systems, TLS protocols, VPNs, identity management, backups, and digital signatures. Pay close attention to assets that include long-term sensitive data, particularly those with confidentiality requirements lasting a decade or more.
2. Crypto-Agility
Build systems that can evolve.
Hardcoded algorithms and static key management will become liabilities in a post-quantum world. Organizations should invest in modular cryptographic frameworks that can adapt as new standards emerge—minimizing disruption while enhancing long-term resilience.
3. Vendor and Third-Party Alignment
Extend readiness beyond internal systems.
Supply chains, cloud platforms, and technology vendors must also be quantum aware. Engage with third parties to evaluate their post-quantum cryptography strategies and timelines. Quantum risk is shared risk, and accountability must span the ecosystem.
4. Executive and Employee Awareness
Position quantum as a business risk, not just a technical one.
Leadership buy-in is essential. CISOs and security teams should brief executive stakeholders and incorporate quantum considerations into security awareness programs and tabletop exercises. This fosters a culture of forward-looking risk management.
5. Standards Engagement and Pilot Projects
Prepare through experimentation.
The U.S. National Institute of Standards and Technology (NIST) has identified algorithms for post-quantum cryptography. Organizations should begin testing these in non-production environments. Pilots in low-risk areas can help teams develop tools and expertise before large-scale transitions are needed.
The Case for Early Action
The quantum era won’t begin with a sudden breach—it will unfold quietly as existing encryption becomes ineffective. Organizations that wait for definitive signs will be left behind. Those that act now can mitigate long-term exposure and demonstrate strategic leadership in a risk-sensitive business landscape.
Take the first step toward quantum readiness.
Start with a quantum risk assessment to understand what’s at stake and build a plan for long-term resilience.
