A Global Wake-Up Call for Cybersecurity Leaders

The Capgemini Research Institute has released a landmark report confirming that quantum security is no longer a theoretical concern—it’s a business imperative. After surveying over 1,000 enterprises with revenues of at least $1 billion, the findings are unambiguous: 70% of respondents are either already working on, or will begin working on, quantum-safe solutions within the next five years.

These "early adopters" span 13 sectors and 13 countries across North America, Europe, and Asia–Pacific, revealing an accelerating shift in enterprise strategy from classical encryption to post-quantum resilience.

Why It Matters: The Quantum Threat Is No Longer Distant

With advances in quantum computing—including Google, IBM, and China’s breakthroughs—cryptographic techniques like RSA and ECC are expected to become obsolete. Enterprises now face a dual risk:

• “Harvest Now, Decrypt Later”: Threat actors can store encrypted data today and decrypt it when quantum computers mature.

• Critical Infrastructure Exposure: From financial services to telecom, outdated cryptography could compromise data integrity, identity systems, and cross-border operations.

Capgemini’s report finds that cybersecurity readiness is now central to quantum adoption plans, often cited as a top-three business risk.

Who’s Leading the Charge?

According to the survey:

• Banking and Financial Services: Nearly 80% of firms are either piloting or planning post-quantum cryptography (PQC) solutions.

• Telecommunications and Energy: Both industries face critical infrastructure exposure and are investing in PQC and quantum key distribution (QKD).

• Healthcare and Pharmaceuticals: Quantum-safe data protection is essential to protect clinical trials, genomic data, and patient privacy.

Regionally, North America leads in investment readiness, but Europe is aggressively aligning policy and enterprise adoption, with Asia-Pacific not far behind.

The Top Strategies Enterprises Are Pursuing

Capgemini’s report highlights a clear pattern among early adopters:

1. Cryptographic Inventory & Risk Mapping Many firms are conducting full audits of current encryption schemes and data lifespan to identify high-risk areas.

2. Pilot Projects in Post-Quantum Algorithms Organizations are testing hybrid cryptographic schemes (e.g., pairing RSA with NIST-approved Kyber or Dilithium algorithms).

3. Vendor PQC Requirements Procurement teams are beginning to mandate quantum-safe roadmaps from third-party software, cloud, and infrastructure providers.

4. Board-Level Awareness & Budgeting 42% of organizations surveyed said quantum risk is now discussed at the executive or board level—a major shift from previous years.

What’s Holding Others Back?

The 30% not yet engaged in quantum-safe efforts cited several challenges:

• Lack of internal expertise

• Uncertainty over standards (still evolving with NIST’s finalization)

• Budget prioritization amid broader digital transformation

However, Capgemini notes that even these organizations are “quantum-aware” and increasingly recognize the inevitability of PQC.

Looking Ahead: From Awareness to Action

Capgemini’s report calls for a “quantum-readiness framework” to help enterprises transition securely. Recommendations include:

• Immediate cryptographic risk assessments

• PQC pilot testing with hybrid algorithms

• Participation in industry-wide consortia and standards efforts (e.g., ETSI, NIST, ISO)

• Internal training for security and DevSecOps teams

Conclusion: Quantum Readiness is Business Resilience

This report sends a clear message: Quantum-safe adoption is no longer niche or academic—it’s mainstream. For billion-dollar enterprises across the globe, the quantum era is not 20 years away—it’s approaching fast.

Those who start planning now—by identifying cryptographic vulnerabilities, testing new algorithms, and training staff—will be well-positioned to thrive in a post-quantum world.

Because in cybersecurity, preparedness isn’t optional—it’s existential.
