The rise of quantum computing is set to transform cybersecurity as we know it. While quantum technology promises breakthroughs in fields like artificial intelligence and materials science, it also introduces significant security risks—particularly to encryption. Most of today’s encryption standards, including RSA and ECC, rely on mathematical problems that quantum computers will eventually be able to solve exponentially faster than classical machines. This means that the very cryptographic methods securing sensitive data today could be obsolete in just a few years.

Becoming quantum-ready is not just a long-term goal—it’s an immediate necessity. Organisations that fail to prepare for the quantum shift risk exposing their sensitive data, failing regulatory requirements, and scrambling for last-minute fixes when the quantum threat becomes real. And while large-scale quantum attacks may not be here yet, cybercriminals are already engaging in “Store Now, Decrypt Later” (SNDL) attacks—stealing encrypted data today to decrypt it when quantum technology matures. The good news? A structured, phased approach can help businesses transition smoothly into a quantum-secure future without disrupting operations.

The first step is to assess your organisation’s existing cryptographic landscape. Identify all encryption protocols in use—are they reliant on RSA, ECC, or other traditional cryptographic methods that quantum computers could eventually break? Once you’ve pinpointed vulnerable areas, the next step is to explore post-quantum cryptography (PQC) solutions. The National Institute of Standards and Technology (NIST) has been leading efforts in PQC standardisation, providing a crucial framework for organisations looking to transition to quantum-resistant encryption.

A critical but often overlooked step is maintaining a comprehensive encryption inventory. Many organisations do not have full visibility into where and how encryption is implemented across their systems, making it difficult to plan for post-quantum migration effectively. Conducting an encryption audit will allow businesses to identify outdated cryptographic methods and prioritise which systems require urgent attention.

Next, look beyond just encryption. Quantum readiness also means ensuring your entire IT infrastructure can support the demands of quantum-era security protocols. This includes making sure your hardware and software are scalable, adaptable, and capable of integrating new cryptographic methods without major disruptions to business operations.

Developing crypto-agility—the ability to swiftly transition between encryption methods—is a key component of future-proofing security. Organisations should focus on solutions that allow for seamless cryptographic upgrades without requiring a complete system overhaul.

A critical element in becoming quantum-ready is collaboration. Quantum security is not a challenge that can be tackled in isolation. Engage with cybersecurity professionals, IT teams, and external consultants to create a structured, future-proof roadmap for quantum security adoption. Leadership buy-in is equally important—executive teams must understand the urgency of the quantum threat and allocate resources accordingly.

Additionally, businesses should stay informed about regulatory developments. Governments worldwide are already moving toward quantum-safe security standards, and organisations that proactively adapt will be ahead of the compliance curve.

Becoming quantum-ready is a phased, long-term process. Don’t expect to make the shift overnight. Begin with mission-critical systems—those that store and process highly sensitive data—and then extend quantum-resistant measures to other areas over time. Regular security assessments, penetration testing, and technology updates will be necessary as quantum advancements continue to unfold.

Another crucial aspect of quantum readiness is employee awareness. Cybersecurity teams must be trained on quantum threats, post-quantum cryptography, and best practices for managing the transition. Integrating quantum risk assessment into ongoing security awareness programmes will ensure that quantum resilience becomes part of an organisation’s broader cybersecurity strategy.

At the same time, organisations must consider the supply chain risks associated with quantum threats. Third-party vendors, cloud service providers, and business partners must also be part of the quantum-readiness strategy. If a critical supplier has weak encryption practices that become vulnerable to quantum attacks, this could pose a significant risk to the entire ecosystem.

Preparing for quantum threats is not just a one-time effort—it requires an ongoing commitment to resilience. Even after transitioning to post-quantum cryptography, organisations must remain agile, continuously monitoring quantum advancements and updating security protocols accordingly.

Investing in quantum-safe key management systems and adopting hybrid cryptographic models—where classical and quantum-resistant encryption work in parallel—can provide additional layers of protection during the transition period.

Becoming quantum-ready is a strategic, multi-phase approach. Start by identifying vulnerabilities, transitioning to post-quantum cryptography, and ensuring your infrastructure is adaptable to future quantum security requirements. Organisations that act now will be in a stronger position to mitigate risks, ensure compliance, and stay ahead in the evolving cybersecurity landscape. Waiting is not an option.
