The era of quantum computing is no longer confined to academic research labs; it is gradually becoming a transformative force across industries. From healthcare breakthroughs and sustainable materials development to optimizing complex systems, quantum computers are beginning to tackle challenges that were once thought insurmountable. Yet, with this transformative potential comes an equally significant threat: the ability of quantum computers to undermine the cryptographic systems that form the backbone of today’s digital security.
As quantum technology advances, the arrival of cryptographically relevant quantum computers (CRQCs) could render widely used public key cryptography algorithms obsolete. These algorithms safeguard the confidentiality of sensitive data, ensure the integrity of digital communications, and authenticate access to critical systems. The implications are profound: data breaches, infrastructure disruptions, and potentially widescale global cyber manipulation.
The threat isn’t just theoretical. Cybercriminals are already harvesting encrypted data today, intending to decrypt it later when quantum capabilities mature—a practice dubbed “harvest now, decrypt later.” This presents an immediate challenge for CIOs and CISOs, demanding proactive measures to secure data against future quantum threats.
However, many IT leaders see quantum computing as a distant concern. Current cybersecurity challenges often overshadow the urgency of addressing quantum risks. Yet, ignoring these threats could jeopardize the digital economy and organizational resilience in the long run. Quantum-safe strategies are not a luxury but a necessity, and the time for CIOs to act is now.
This article delves into why CIOs must take the lead in preparing their organizations for the quantum era, ensuring robust defenses against an evolving threat landscape.

Building Quantum-Safe Resilience: A Strategic Approach
Adopting Quantum-Safe Cryptography
Organizations must begin integrating quantum-safe cryptographic measures to mitigate the imminent “harvest now, decrypt later” threats. A structured quantum-safe transformation program is essential to address vulnerabilities and establish resilience against future quantum risks. This program typically follows three distinct phases: preparation, organizational transformation, and migration.
Preparing Teams and Assessing Risks
The first step involves creating awareness across the organization. Stakeholders and security experts should be educated about quantum risks through dedicated campaigns. Establishing quantum-safe “champions” within teams can ensure consistent focus and strategic alignment.
A thorough risk assessment is critical at this stage. This includes identifying cryptographically relevant business assets and evaluating their risk levels based on complexity, business relevance, and potential migration difficulties. The resulting assessment report should outline vulnerabilities, highlight urgent actions, and provide a clear quantum risk posture for the organization. Additionally, building a comprehensive cryptography inventory lays the foundation for future-proofing the enterprise.
Preparing for Transformation
Once risks are identified, focus shifts to prioritizing vulnerabilities and planning remediation actions. Key initiatives at this stage include developing governance frameworks for cryptography, ensuring systems are compatible with post-quantum cryptography (PQC) algorithms, and producing a Cryptography Bill of Materials (CBOM).
Stakeholder collaboration is essential to understand third-party dependencies and update procurement processes to support quantum-safe solutions. Creating a roadmap that includes these initiatives provides a structured path to secure the organization’s cryptographic infrastructure. Establishing cryptographic observability—monitoring progress through automatic data analysis—helps stakeholders track the adoption of PQC measures.
Executing the Migration
The final phase involves implementing the migration strategy. Organizations must prioritize systems based on risk, strategic objectives, and cost considerations. Standardized architectures and migration patterns help facilitate a seamless transition.
Key actions include enabling cryptographic agility within development processes and decoupling cryptographic operations to centralized platforms for better governance and adaptability. A continuous feedback loop ensures that lessons learned inform ongoing improvements, fostering innovation and resilience during the migration journey.
Overcoming Challenges
Transitioning to PQC presents unique challenges. Migrating core cryptographic services such as PKI, secure payment systems, and mainframes demands addressing dependencies and interoperability issues. Performance testing is essential to ensure compatibility with existing workflows, as PQC often involves longer key sizes and altered encryption dynamics.
Knowledge gaps, hardcoded cryptographic information, and poorly managed encryption keys add further complexity. Organizations must also account for specific configurations and unique use cases that may not have been fully tested by global PQC standards.
The Role of Governance and Collaboration
A robust governance framework is vital for aligning quantum-safe strategies with organizational goals. This includes regulatory compliance, cryptographic assurance, and capacity building. Cross-departmental collaboration and partnerships within industries can drive collective progress, enabling organizations to share insights and tackle common quantum challenges.
Staying Ahead of Regulations
Regulations surrounding PQC are rapidly evolving. Frameworks such as the EU’s Digital Operations Resilience Act (DORA), Singapore’s MAS guidelines, and PCI DSS v4.0.1 already emphasize the importance of cryptographic inventories and quantum risk management. Organizations must proactively adapt their cryptography governance strategies to stay ahead of compliance requirements.
A Long but Crucial Journey
Transitioning to a quantum-safe future is a complex, multi-year initiative that demands cross-functional engagement and a focus on team cohesion. Organizations must also invest in continuous learning, operational traceability, and ecosystem partnerships to ensure successful transformation. By addressing these challenges head-on, businesses can safeguard their digital assets and maintain resilience in the quantum era.
Three Critical Steps to Achieve Quantum-Safe Security
As quantum computing advances, traditional cryptographic systems are at risk. To protect sensitive data, organizations must adopt quantum-safe security practices. Here are the three essential steps for securing your enterprise:
1. Identify Cryptographic Vulnerabilities
Begin by assessing your current cryptographic systems. Identify which ones are vulnerable to quantum threats and create a detailed inventory of all cryptographic assets across applications, networks, and third-party products. Tools like the Cryptography Bill of Materials (CBOM) can help track this information and ensure no cryptographic component is overlooked.
2. Evaluate Risk and Prioritize Assets
Next, observe how quantum vulnerabilities impact critical business data. Work with cybersecurity teams to prioritize sensitive data most at risk from future quantum decryption capabilities. Focus on high-value assets and implement a mitigation strategy based on the complexity of securing each asset.
3. Adopt Quantum-Resistant Cryptography
Transform your cryptographic infrastructure by integrating quantum-safe solutions. Test new protocols before deployment, ensuring they align with existing systems without compromising performance. Work with vendors to understand their plans for adopting quantum-safe encryption and ensure your organization can integrate updates as needed.
