Post-quantum readiness

Secure trust before quantum risk becomes business risk

Quantum computing is reshaping the cybersecurity landscape and challenging the cryptographic foundations of today’s digital economy. Public‑key encryption underpins identity, payments, cloud, applications, and data exchange. Much of it was not designed to withstand a quantum‑capable adversary.

With “harvest now, decrypt later,” sensitive data captured today can be exposed tomorrow.

Post-quantum readiness is now a business priority.

Move from exposure to execution

Post‑Quantum Readiness by Capgemini helps organizations move from cryptographic exposure to governed, crypto‑agile resilience, protecting long‑lived data, meeting emerging regulatory expectations, and sustaining digital trust.

We help you identify where quantum risk resides, prioritize what matters most, and execute a structured migration, without disrupting operations.

How we help you become quantum-ready

From discovering cryptographic exposure to executing enterprise-wide migration, Capgemini helps organizations build a practical, governed, and scalable path to quantum-safe security.

Understand where quantum risk exists, what it means for your business, and where to act first. Establish an enterprise-wide understanding of quantum risk and its potential impact on business continuity, regulatory compliance, customer trust, and long-term data protection.

Capabilities include:

  • Cryptographic discovery and Cryptographic Bill of Materials (CBOM) creation
  • Risk and maturity assessments aligned to NIST PQC standards
  • Prioritization across applications, infrastructure, PKI, APIs, cloud services, OT, IoT, and third-party ecosystems

Embed post-quantum readiness into enterprise decision-making and transformation programs. Establish the governance frameworks, policies, and operating model needed to embed post-quantum readiness across the enterprise.

Capabilities include:

  • Governance frameworks and executive reporting
  • Policy alignment across cybersecurity, architecture, legal, compliance, and procurement
  • Cryptographic policy, key management, and certificate lifecycle governance
    Stakeholder alignment and organizational change management

Validate post-quantum cryptography in real-world environments through targeted pilots that build confidence, prove feasibility, and establish repeatable migration patterns.

Capabilities include:

  • Hybrid PQC and crypto-agility pilots
  • PKI modernization and KMS/HSM integration
  • TLS, signing, identity, and certificate modernization
  • Reference architectures, migration playbooks, and reusable patterns

Industrialize post-quantum migration and sustain crypto-agility at scale. Execute a phased transition to quantum-safe cryptography while maintaining operational resilience, regulatory compliance, and business continuity across complex technology environments.

Capabilities include:

  • Phased migration roadmap and migration factory model
  • Delivery governance, testing, assurance, and operational monitoring
  • Remediation across applications, infrastructure, cloud, OT, IoT, and partner ecosystems
  • Continuous crypto-agility and operational resilience
