UK cyber agency suggests 2035 deadline to move to quantum-safe encryption, warns of threats

Security experts warn that while the technology is still in its early stages, its implications for cybersecurity cannot be ignored.

“I believe this has the potential to create cross-border cyber threats, including proxy cyber wars or enemy nation-sponsored cyber terrorism,” said Faisal Kawoosa, founder and lead analyst at Techarc. “It’s complex and costly to use quantum computing even for cybercrimes. So, at this stage, it could only be government-supported and used against unfavorable nations. Given the current state of international relations, the risk appears high.”

This growing risk underscores the urgency of transitioning to PQC before adversaries develop the means to exploit vulnerabilities at scale. Organizations that delay migration could find themselves exposed to quantum-enabled attacks sooner than anticipated.
