Key takeaways from the NCSC’s urgent call for PQC migration

April 1, 2025

The Quantum Threat is Coming – Are You Ready?

The National Cyber Security Centre (NCSC) has just issued its strongest warning yet: the race to protect data from quantum threats has begun, and organizations must start preparing now. Their newly released PQC Migration Timelines report lays out a clear roadmap for transitioning to post-quantum cryptography (PQC), with a deadline of 2035 for full adoption.

For organizations handling sensitive data, the implications are clear—the security measures we trust today could be obsolete tomorrow. But the real question is: Are you prepared for a world where quantum computers can crack today’s encryption?

The Quantum Threat: Why Act Now?

Quantum computing has long been a futuristic concept, but it’s advancing faster than expected. When sufficiently powerful quantum computers arrive, they’ll have the ability to break traditional encryption methods like RSA and ECC—methods that protect everything from financial transactions to national security communications.

The risk isn’t just theoretical. “Harvest now, decrypt later” attacks are already happening, where adversaries collect encrypted data today, knowing they’ll be able to break it when quantum technology matures. That means data is already at risk, even before quantum computers become mainstream.

The NCSC’s Roadmap: When Should You Migrate?

The NCSC’s report outlines a phased migration plan:

• By 2028 – Identify and assess where cryptographic upgrades are needed
• By 2031 – Begin rolling out PQC solutions, prioritizing critical areas
• By 2035 – Complete the transition to quantum-safe encryption

This timeline might sound like a distant concern—but waiting is not an option. The transition to PQC is complex, and failure to act now could leave organizations scrambling to retrofit security under pressure.

What This Means for You

For enterprises and network providers, the message is clear:

• Encryption agility is key– Future-proof your networks with modular, adaptable cryptographic solutions.
• PQC readiness must start today– Inventory your cryptographic assets and assess vulnerabilities.
• Speed and performance matter– New encryption methods must secure data without sacrificing network speed and efficiency.
