Quantum computing continues to advance, but many organizations are still in the early stages of preparing for what those advances could mean for existing encryption and long-lived sensitive data.
A recent ITPro feature examines the enterprise readiness gap around post-quantum security and the prospect of “Q-Day,” the point at which sufficiently capable quantum computers could threaten widely used cryptographic systems. The article features perspective from Arjun Kudinoor, quantum security advisor at Protegrity, who emphasizes the need for organizations to build quantum literacy, assess their exposure, and begin identifying where action matters most.
Why Quantum Readiness Is Becoming an Enterprise Priority
ITPro highlights research showing that many organizations remain unprepared for quantum-related security risks, even as expectations around the timeline for cryptographically relevant quantum computing continue to evolve.
The challenge is not simply choosing a new cryptographic algorithm. Enterprises first need to understand where vulnerable cryptography exists, which systems and data require the greatest protection, and how long that information needs to remain secure.
Protegrity Perspective on Building Quantum Literacy
Arjun Kudinoor points to knowledge and expertise as an important part of the readiness gap. Organizations need technical teams that can understand emerging quantum risks, assess existing systems, and identify where quantum computing may create either security challenges or meaningful business opportunities.
He recommends developing quantum literacy across both technical and executive teams, evaluating exposure to quantum-enabled cybersecurity threats, and identifying problems where quantum computing could provide a meaningful advantage.
Preparation Starts With Prioritization
The article makes clear that becoming quantum-ready will not happen through a single migration project. Organizations may need to modernize cryptography across applications, infrastructure, data stores, certificates, APIs, and other systems over an extended period.
That makes prioritization important. Rather than waiting for perfect certainty around when quantum systems will become capable of breaking current encryption, organizations can begin by identifying their most sensitive and long-lived data, understanding where cryptographic dependencies exist, and creating a roadmap for modernization.
Why Waiting for “Q-Day” Creates Unnecessary Risk
Quantum risk is unlikely to appear as a single overnight event. Different cryptographic technologies may become vulnerable at different times, while “harvest now, decrypt later” scenarios create concern for information that may need to remain confidential for years.
For enterprise leaders, the practical takeaway is to start preparing before the technology reaches that threshold. Building awareness, understanding cryptographic exposure, prioritizing critical assets, and developing a migration strategy can help organizations make measured progress without rushing into poorly planned changes.
