The G7 tells industry to hurry up and prep for post-quantum encryption
G7 nations urge industry to accelerate post-quantum encryption adoption.
A G7 cybersecurity working group is pushing governments and industries to speed up their transition to post-quantum cryptography (PQC). The report emphasizes that the threat of quantum computers breaking current encryption is a near-term economic and business risk, not just a theoretical cryptographic one. While some sectors like finance are progressing, others are lagging due to more immediate concerns, highlighting the need for collective, coordinated planning.

The lesson from this incident
Full lessonThe G7 cybersecurity working group is warning that quantum computing poses a near-term, real-world threat to current encryption standards, not merely a distant theoretical risk. Organizations that delay transitioning to post-quantum cryptography (PQC) face potential exposure of sensitive data through 'harvest now, decrypt later' attacks, where adversaries collect encrypted data today to decrypt once quantum capabilities mature. Critical sectors such as finance, healthcare, and government infrastructure are especially at risk given the long lifecycle of their systems and the sensitivity of their data. The uneven pace of adoption across industries creates systemic vulnerabilities, as interconnected supply chains and financial networks are only as secure as their weakest cryptographic link.
What helps against this
How we list vendors- Vulnerability scanning and prioritisation
You know which systems are vulnerable, and which ones to fix first.
- Cyber asset inventory
You cannot patch, monitor or protect the devices, cloud resources and accounts you do not know you have.
- Encryption and key management
Stolen data stays unreadable, and the keys stay under your control.
