Substantive updates to this site.
Reverse-chronological log of substantive updates. Each entry states the date, the page touched, what changed, and why. No cosmetic freshness updates. The site is not republished because a calendar quarter ended.
An internal audit found that no monetary figure on this site traced to a primary source. The audit-firm fee tables, the tier bands, the auditor rate card, the per-criterion percentage, the control-overlap figure, the bundle-saving and year-two ratios, and the calculator's coefficients were all estimates presented as data. They have been removed rather than adjusted, because there was nothing to adjust them against: no CPA firm publishes SOC 2 fees, at any tier. In their place, two things. The GRC platform prices are now read off each vendor's own AWS Marketplace listing, in the vendor's currency, unit and employee band, carrying the date the listing was checked; the platform page previously priced five vendors from buyer-survey figures and ranked them in an order the published SKUs do not support. And the calculator has been rebuilt bottom-up: it assumes an hour count from your scope, you supply the rates, and the total is the arithmetic of the two, with every assumption listed on the methodology page and labelled as ours. Where a figure could be neither sourced nor honestly modelled, it is now absent and the page says why.
The home and methodology pages stated that Impact-network affiliate relationships with GRC platforms existed and were disclosed where each platform appeared. No such affiliate links or disclosures exist anywhere on the site, and the site's stated position (and the header disclaimer) is unaffiliated, with no vendor referral fees. Replaced the language with a plain statement that the site takes no referral or affiliate fees from GRC platforms or audit firms and that no figure is influenced by a commercial relationship.
Search demand for what the Trust Services Criteria are (TSP Section 100, the 2017 criteria with 2022 revised points of focus) was landing on a purely cost-angled page. Added a factual reference section and two FAQ entries, sourced to the AICPA TSP Section 100 document, clarifying that the criteria themselves did not change in 2022 and there is no separate 2024 or 2026 edition.
