Quantum readiness is becoming a planning issue long before quantum computing reaches full maturity. Organizations can start now by understanding where cryptographic exposure exists, prioritizing the systems that matter most, and building the technical knowledge needed to make measured decisions over time.
In a recent Cybersecurity Insiders article published for World Quantum Readiness Day, Protegrity’s Arjun Kudinoor shares a practical view of what that preparation can look like — from identifying vulnerable systems and phasing post-quantum cryptography migration to building stronger quantum and PQC literacy across technical and leadership teams.
Quantum Readiness Starts Before the Technology Fully Matures
Arjun emphasizes that organizations do not need to wait for fault-tolerant quantum computing to become widely available before taking action.
One of the most immediate areas to address is cybersecurity. Organizations can begin by identifying systems that rely on cryptography that may become vulnerable to future quantum capabilities and determining which systems should be prioritized first.
This gives teams a clearer starting point for post-quantum planning rather than waiting until migration becomes urgent.
Prioritize High-Value and Publicly Accessible Systems
Arjun recommends beginning post-quantum cryptography migration with the highest-priority systems and those that are most publicly accessible.
A phased approach can help organizations focus resources where they matter most while developing a broader understanding of how cryptographic changes may affect applications, infrastructure, and data protection strategies over time.
The goal is to create a practical roadmap that connects near-term security priorities with longer-term technology planning.
Build Quantum and PQC Literacy Across the Organization
Technical preparation is only part of quantum readiness. Organizations also need people who understand the technology well enough to evaluate new developments, separate meaningful progress from hype, and make informed investment decisions.
Arjun points to quantum and post-quantum cryptography literacy as an important part of that preparation. Teams with the right knowledge can assess potential risks, identify relevant opportunities, and provide leadership with clearer guidance as the technology evolves.
Turn Readiness Into a Long-Term Roadmap
Quantum preparation also requires sustained planning. Organizations need to account for the people, technical expertise, and resources required to evaluate systems and carry out post-quantum initiatives over time.
Arjun notes that organizations with strong technical teams, dedicated budgets, and executives willing to plan for post-quantum adoption will be better positioned to respond as the technology develops.
Rather than reacting to individual announcements, a structured roadmap gives organizations a way to make measured decisions based on their own systems, priorities, and exposure.
