Cover of the guide: A practical path to post-quantum readiness, by Giles Otomewo, Investgao Cyber
// From uncertainty to clarity

Quantum risk doesn't have to be another impossible task

Most organisations know quantum computing will break today's encryption one day. Few know where their cryptography lives, which data is really at risk, or where to start.

This guide cuts through the hype. No exhaustive framework, no vendor pitch: a clear explanation of the threat, the standards and timelines that matter, and a practical roadmap you can start on this quarter.

"Attackers are already stealing encrypted data to unlock later. This guide is about practical steps leaders can take now, built on real-world incident experience, not theory." Giles Otomewo · Founder & CEO, Investgao Cyber

Turn a quantum headline into a plan you can defend

Identify which of your data is already at riskUsing "harvest now, decrypt later" and a simple test to spot long-lived secrets.
Understand the standards and deadlinesNIST's FIPS 203, 204 and 205, and the UK NCSC's 2028, 2031 and 2035 milestones.
