Introduction to Quantum Computing Risks

A recent report published by the Capgemini Research Institute, titled "Future encrypted: Why post-quantum cryptography tops the new cybersecurity agenda," highlights the increasing threats posed by the rapid progress of quantum computing to current encryption algorithms. The report emphasizes that organizations must adopt post-quantum cryptography to safeguard against potential data breaches and regulatory penalties.

The Threat of Quantum Computing

According to the report, approximately two-thirds (65%) of organizations are concerned about the rise of "harvest-now, decrypt-later" attacks, which could render current encryption algorithms obsolete. One in six early adopters believes that "Q-day" will arrive within five years, while around six in ten believe it will arrive within a decade. Marco Pereira, Global Head of Cybersecurity, Cloud Infrastructure Services at Capgemini, states, "Quantum readiness isn’t about predicting a date–it’s about managing irreversible risk. Every encrypted asset today could become tomorrow’s breach if organizations delay adopting post-quantum protections."

Adoption of Quantum-Safe Solutions

High-risk industries, such as defense and banking, are leading the adoption of quantum-safe solutions. In contrast, consumer-focused sectors, like consumer products and retail, are showing less urgency. Most organizations surveyed (70%) are protecting their systems against emerging quantum threats by adopting post-quantum cryptographic (PQC) algorithms. They view PQC as the best option to address near-term quantum security risks because it provides a comprehensive approach to securing data.

Migration to Post-Quantum Cryptography

Nearly half of early adopters are already exploring, assessing feasibility, or piloting PQC solutions. For 70% of organizations, regulatory mandates are a key driver behind the shift to PQC. However, a few organizations (30%) are still ignoring the quantum threat, struggling to allocate sufficient budget and personnel to cryptographic transition.

Conclusion

The rapid progress of quantum computing poses significant threats to current encryption algorithms, and organizations must adopt post-quantum cryptography to safeguard against potential data breaches and regulatory penalties. As Marco Pereira emphasizes, "Quantum safety is not a discretionary spend but a strategic investment, which can turn a looming risk into a competitive advantage." Organizations that recognize this fact early will best insulate themselves against future cyber-attacks.
