CISA, G7 cyber group call for move to post-quantum cryptography

CISA said it and the Group of Seven Cyber Security Working Group have released a call to action urging organizations and governments to begin transitioning to post-quantum cryptography, or PQC, to prepare for quantum computing threats.

The agency said the move is intended to help protect sensitive data, authentication systems and critical assets. CISA published the page, titled Preparing for the Post-Quantum Era: A Call to Action, on Sept. 3, 2026.

Governments and businesses are assessing how to secure systems against future quantum computers, which could weaken some widely used encryption methods. CISA said the call to action is tied to critical infrastructure security and resilience, cybersecurity best practices and information and communications technology supply chain security.

According to CISA, the G7 Cyber Security Working Group's call to action lays out five priorities for a successful transition to PQC. The extracted source text provided by CISA does not include the full list of those priorities.

CISA did not provide additional details in the extracted text about timelines, required steps or specific sectors beyond the general call for a transition.
