Post-Quantum Cryptography

Crypto-agility at scale, which is an inventory and mass-change problem before it is a cryptography problem.

Also known as PQC, Quantum-Resistant Cryptography, Crypto-Agility

5 disciplines across 2 years. That is not a landscape — there is not enough time on the horizontal axis for an oblique view to have any depth — so the same measurement is shown with time collapsed. Each bar is the work running in that domain, weighted by what failure would have cost and summed over the years this technology was in use — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Same arithmetic as the surface elsewhere on the site, one axis fewer. Only the work that used this technology is counted.

Originated and led a thirty-six-month joint research program between NRI North America and the group’s parent company, as technical lead and subject-matter expert — proposed in December 2025, accepted in January 2026, and built to prepare clients in both regions for the transition to quantum-resistant cryptography.

The lab environment behind it ran on the practice’s virtualized cluster. The work was assessing cryptographic estates and turning an unfamiliar technology into approved patterns delivery teams could adopt.

The governing insight is that crypto-agility at scale is an inventory and mass-change problem before it is a cryptography problem. Knowing what algorithms are in use, where, and what depends on them is the hard part; replacing them is the part that has a vendor.

The inventory comes first, and it comes off the wire. Documentation describes the cryptography an estate was designed to use; packet analysis shows what it is actually negotiating, and the difference between those two lists is the work. It is why this discipline starts on a capture platform rather than on a cipher suite.
