The NCSC has set out what it calls a “perfect storm” of cyber risk: the long-term threat quantum computing poses to today’s encryption, alongside more active nation-state actors and a rise in hacktivism. It’s a reminder that the threat landscape is broadening, not narrowing.
Why it matters
Quantum feels distant, but the principle matters now: attackers can “harvest” encrypted data today and decrypt it later once the technology matures. That raises the stakes for how long your sensitive data stays sensitive, and where it lives.
You don’t need to solve quantum this year, but you do need the fundamentals that make any of these threats harder — strong encryption, tight access control, patched systems and a clear picture of what data you hold and where. We help clients get those foundations right and keep an eye on how the guidance evolves.
