No vendor has been rated yet
The criteria are published first, deliberately. When there is enough evidence to justify a verdict, rated vendors appear here grouped by tier, each linking to the write-up and the sources behind its placement.
6 tiers
Published now so the scale can be judged before anyone is placed on it.
Leads on cryptographic substance across nearly every dimension, with independently verified correctness and performance, and discloses its own limitations without being asked.
Strong across most dimensions with independent verification available, and no conformance failures. Gaps exist and are visible rather than hidden.
Solid on the fundamentals, with meaningful gaps — commonly in independent verification, transparency, or protocol integration depth.
Real post-quantum capability exists, but substantiation is thin: claims outrun published evidence on several dimensions.
Falls short on a dimension that cannot be traded off — most directly, failing correctness against the standard the vendor itself claims. A conformance gate lands a vendor here regardless of its other scores.
Not enough public signal to rate, and no cooperation offered. This is explicitly not a judgement about quality: a vendor here has not been found wanting, it has not been assessable. In a market this young, expect this tier to be populated rather than empty.
