CISA, G7 Urge Post-Quantum Cryptography Action

• CISA and a working group are urging organizations to begin transitioning to post-quantum cryptography
• The groups identify five priorities, including raising awareness, developing national strategies and advancing R&D.
• Explore emerging cyber threats at the 2026 Homeland Security Summit on Nov 10

The Cybersecurity and Infrastructure Security Agency and the G7 Cybersecurity Working Group are urging governments and organizations to begin transitioning to post-quantum cryptography, or PQC.

The threat posed by quantum computing is forcing government agencies to rethink how they protect sensitive information and critical systems. 

As DHS continues to prioritize cyber defense and homeland security technology, the transition to post-quantum cryptography is becoming an increasingly important component of federal cybersecurity. The 2026 Homeland Security Summit will bring together government and industry leaders to discuss emerging cyber threats, technology modernization and strategies for strengthening the nation’s security posture.

Why Is CISA Calling for Post-Quantum Cryptography Action?

CISA warned Thursday through its Preparing for the Post-Quantum Era: A Call to Action publication that advances in quantum computing could eventually enable cryptographically relevant quantum computers to break public-key cryptography currently used to protect digital infrastructure.
