The Accredited Assessor Directory carries 1 published figure read from 3 sources' own pages, from 2,500 to 2,500 count, read 11 September 2026.
Attestvio sells its own paid plan in this category (our pricing). It is not counted here: every figure in this index is another provider's own published price, read from its own page.
3 of the 35 named sources read in full publish a figure; 32 publish none, read 11 September 2026.
Every figure, with its source
One row per source: the figure the source's own page publishes, the page, and the day it was read. A figure that is not on a page we read is not on this one.

Methodology
Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).
3 of the 35 named sources that could be read published a usable figure; 32 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere.
The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in count (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 11 candidate sentence(s) were refused by a reviewer with the reason recorded.
The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): the roster of accredited assessors joined ACROSS the registers nobody joins - the PCI SSC QSA listing, the HITRUST authorised assessor directory, UKAS and ANAB through IAF CertSearch, CREST and IASME - one row per firm with the accreditations it actually holds, the regimes and markets it covers, and whether it publishes a fee.
The derivation is the JOIN and the fee-publication rate: how many firms hold more than one accreditation, how many markets have fewer than five accredited bodies, and what the published DPO retainer is by market.
11 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
