Post-Quantum Transition – Readiness Assessment

The Quantum Threat

Quantum computing is rapidly reshaping the cybersecurity landscape. Algorithms like RSA and ECC, which currently safeguard digital communications, financial systems, and identity verification, are expected to be broken by quantum attacks. This introduces a critical vulnerability: encrypted data intercepted today may be decrypted in the future—a scenario known as “harvest-now, decrypt-later.”

This is not a distant or speculative concern. The European Commission, NIST, and CCN-PYTEC have published clear migration timelines and strategic recommendations. Inaction today compounds crypto-debt and increases operational exposure, putting long-term confidentiality and authentication—core pillars of digital trust—at risk.

The Post-Quantum Transition

Post-Quantum Cryptography (PQC) offers a strategic path forward, with algorithms designed to resist quantum attacks. However, transitioning to quantum-safe cryptography is a complex challenge. It requires years of coordinated planning, internal discovery, and risk prioritization.

This transition is not just a technical necessity—it is a strategic capability. Organizations must identify where cryptography is used, assess the criticality and secrecy lifespan of protected data, and map dependencies across systems. Early preparation enables companies to migrate at their own pace, avoid rushed deployments, and embed crypto-agility into their architecture.

The readiness phase is essential. It allows organizations to align with international standards, anticipate regulatory requirements, and build resilience into their digital infrastructure.

Quantum-Safe Services at Applus+ Laboratories

Applus+ Laboratories offers a structured readiness assessment service to support organizations preparing for the quantum-safe transition. Our methodology is designed to help teams build clarity, define priorities, and establish a secure migration strategy.

Cryptographic Landscape Discovery

We begin by mapping the cryptographic landscape across your organization. This includes identifying where cryptography is used, which algorithms are deployed, and what systems protect sensitive data. The result is a Cryptographic Bill of Materials (CBOM) that highlights critical assets and long-secrecy data, forming the foundation for strategic planning.

Quantum Risk Assessment

Next, we assess how quantum computing impacts your specific environment. We prioritize systems with high exposure—those protecting long-lived sensitive data, relying on legacy cryptography, or involving third-party dependencies. This phase delivers a clear, prioritized risk profile that guides the transition roadmap.

Post-Quantum Roadmap Definition

Finally, we support the definition of a phased migration plan aligned with international standards. This roadmap translates risks into actionable priorities, defines timelines, and minimizes operational disruption. It empowers internal teams to execute confidently and ensures long-term security and compliance.
