How Coldproof turns post-quantum change into a migration budget
From measured cryptographic performance to a financial model security and finance can use.
Measure what actually changes.
Post-quantum cryptography changes more than an algorithm name. It can change operation time, handshake behavior, signatures and keys, certificate sizes, protocol overhead, throughput and the way infrastructure behaves under load.
Coldproof starts with measured evidence from PQC Arena rather than a generic performance assumption. The run, machine and software environment stay attached to the number so the evidence can be inspected.

Measurement tells us what changed. It does not yet tell us what that change costs your organization.
Put those changes inside your estate.
A benchmark alone cannot price a specific organization’s transition. The same cryptographic change can land very differently in a payments gateway, an internal service mesh, a certificate authority or an embedded device fleet.
Coldproof maps measured effects onto the systems that create work and cost. Customer inputs may include certificate volumes, HSM footprint, application estate, connection volumes, infrastructure profile and migration timing. These are explicit inputs—not claims of fully automated estate discovery.
Where does a cryptographic change become an operational change?
and protocol effects
Turn infrastructure effects into money.
Measured effects and customer inputs feed a multi-year migration model. The model separates the transition project from the infrastructure and operating-cost differences that can remain after implementation.

- →Threshold-driven cost changes
Give security and finance the same number.
The purpose is a decision-ready migration view, not another technical report. Security can see what drives the estimate; finance can see when cash is required, what remains uncertain and which assumptions deserve another measurement.
- 01How much should we budget?
- 02When will the largest costs occur?
- 03Which assumptions change the answer most?
- 04Where could infrastructure capacity force a step-change in cost?
- 05What should we measure next before committing the budget?

We’re working with a small number of organizations to model the economics of their post-quantum transition.
