New Guidance Helps Businesses Check If Their Tech Vendors Are Ready for Quantum-Safe Security

ACSC · 16 July 2026

Key Takeaway Start asking your key software and IT vendors about their post-quantum cryptography plans now, so your business isn't scrambling to catch up later.

The Australian Cyber Security Centre (ACSC) has published new guidance designed to help organisations evaluate how ready their vendors are for post-quantum cryptography (PQC). Quantum computers, once mature, could potentially break the encryption methods that currently protect much of the world's digital data, making the transition to quantum-resistant security an important long-term priority for all businesses that rely on digital systems.

For small and medium businesses, this may seem like a distant concern, but many SMBs depend heavily on third-party software, cloud services, and IT vendors to handle sensitive data. The new guidance encourages organisations to start conversations with these vendors now, asking about their roadmaps and plans for adopting quantum-resistant encryption standards, so that future upgrades can happen smoothly rather than under pressure.

While the shift to post-quantum cryptography will happen gradually over the coming years, early preparation reduces the risk of being caught off guard when quantum computing capabilities advance. Understanding vendor readiness is a key part of managing this transition, particularly for businesses that handle sensitive customer or financial information with long-term confidentiality requirements.
