Post-Quantum Cryptography & Readiness Advisory

Preparing Today for the Threats of Tomorrow

Is your encrypted data safe from future threats?

Post-quantum cryptography will break today’s encryption standards. Our post-quantum readiness service helps you prepare now – before your data becomes vulnerable.

Quantum computing poses an existential risk to current encryption algorithms like RSA, Diffie-Hellman, and ECC – the very foundations of SSL/TLS, VPNs, and digital signatures. As these machines advance, they will render today’s cryptography obsolete, exposing sensitive systems and data to unprecedented threats.

NSI Global’s quantum risk assessment and readiness service helps organisations assess where they’re vulnerable and guides a proactive transition to quantum-resistant cryptography. We help you understand the risks, prioritise what matters, and align with global frameworks such as NIST’s post-quantum standards.

What We Assess

Crypto Inventory & Mapping

Catalogue cryptographic assets, protocols, and dependencies across systems.

Quantum Risk Assessment

Evaluate how and where your current encryption will fail under quantum attack.

Migration to Quantum-Resistant Cryptography

Develop a strategic roadmap for migrating to quantum-resistant cryptography, guided by our Cyber Posture Consulting team.

Governance & Readiness Reporting

Board-level reporting on organisational risk exposure, compliance, and migration timelines.

Why It Matters

  • Post-quantum threats are inevitable — action must be taken before existing systems fail.

  • “Harvest now, decrypt later” attacks are already targeting long-lived encrypted data.

  • Regulatory mandates for crypto-agility are fast approaching.

  • Rushing migration later could introduce new vulnerabilities or break key infrastructure.
