Post-Quantum Cryptography Readiness Consulting

Future-Proof Your Security Against Quantum Threats

Quantum computing is rapidly advancing, and when commercially viable systems emerge, today’s standard cryptography (RSA, ECC and others) will be rendered vulnerable. Threat actors are already capturing and storing encrypted data with the intention to decrypt it later with quantum capability.

Organisations holding sensitive or long-lived data—including defence, critical infrastructure, financial services, healthcare, research and enterprise—must begin transitioning to quantum-resistant security now to avoid catastrophic compromise.

NSI Global delivers Post-Quantum Cryptography (PQC) Readiness Consulting to help Australian organisations assess risk, develop migration strategies, and prepare for the shift to quantum-safe encryption.

Prepare for the Post-Quantum Era

We provide full lifecycle guidance to evaluate cryptographic exposure, prioritise risk areas and build a structured transformation pathway in alignment with
  • NIST PQC standards and approved algorithms
  • ASD Essential Eight, ACSC guidance and Security of Critical Infrastructure Act (SOCI)
  • ISO 27001, IRAP & DISP requirements
  • Zero-Trust security architectures and sovereign national-security frameworks

Why Post-Quantum Readiness Cannot Wait

Quantum computing will break the cryptography protecting:
  • Defence and intelligence communications
  • Government Identity and Secure Satellite Systems
  • Banking, Payments and National Financial Systems
  • Energy, Aviation and Transport Infrastructure
  • Healthcare, Research and Pharmaceutical IP
  • Enterprise Cloud and Authentication Frameworks
The impact will redefine national security and business continuity across Australia.

Frequently Asked Questions

What is Post-Quantum Cryptography (PQC)?

Post-Quantum Cryptography refers to next-generation encryption designed to withstand attacks from quantum computers. Unlike traditional cryptographic methods such as RSA and ECC—which quantum computing will be able to break—PQC uses quantum-resistant algorithms approved by standards bodies such as NIST.

Why do organisations need to start preparing now?

Threat actors are already harvesting encrypted data today with the intent to decrypt it once quantum capability becomes widely available. This means long-term sensitive data is at risk now, even if it appears secure today. Migration to quantum-safe encryption requires strategic planning, system inventory, testing and staged implementation, and cannot be done instantly once quantum systems mature.

Which industries are most affected by quantum-level threats?

Any organisation responsible for long-term or high-value data is at elevated risk. This includes defence, government, critical infrastructure, telecommunications, energy, financial services, healthcare, aviation, research institutions, technology providers, and enterprise cloud environments.

What does a PQC Readiness Assessment involve?

Our assessment identifies current cryptographic usage across networks, cloud environments, applications and devices, highlights vulnerabilities, and develops a migration roadmap aligned to NIST standards, ASD/ACSC guidance, ISO 27001 and SOCI Act requirements. We also provide executive-level recommendations and phased implementation support.

Don’t Wait Until Quantum Computing Breaks Encryption

Quantum disruption is inevitable—and once quantum capability becomes practical, the window to act will be gone. Organisations managing sensitive or high-value data must begin their transition before encryption fails.
