Observatory · Dependency graph

The migration dependency graph

The real question is not 'is post-quantum cryptography standardised?' It is whether every product, protocol, appliance, trust anchor, device and vendor on the critical path can support a compatible migration before your risk deadline. Each node below is wired to the named products we could verify — and to the layers where no first-party evidence exists at all.

Evidence

Vendor readiness, stated precisely

A green checkbox has to mean something specific. Each record below names the product release, the capability, the evidence, the evidence class and the verification date — plus what must not be inferred. Where no first-party statement exists, that absence is recorded rather than guessed.

How to read these labels
Shipping
A generally available product release implements the NIST algorithms; documented by the supplier or the project itself.
Partial
Some paths are post-quantum (usually key exchange) while others — typically authentication, signing or key custody — are not.
Announced
A dated public commitment or preview exists, but no generally available implementation has been verified.
No public evidence
No first-party statement of post-quantum support was found for this layer. Absence of evidence is recorded as absence, not as failure.
