Methodology

Everything here is either verified public data or clearly-framed buyer education. We do not fabricate credentials, statistics, case counts, ratings, or reviews. This site is a sourcing directory FOR vendor-verification service providers; it does not itself perform business verification, KYB checks, or sanctions screening, and it does not verify, certify, or vouch for any listed vendor's service quality.

Vendor reference data

The 30 vendors in the reference layer are real, publicly-documented vendor-verification, KYB, due-diligence, and sanctions-screening companies. Each record was researched and then independently re-verified via web search before publication, with source URLs recorded. Only well-documented, notable firms are included; we do not invent or list unverifiable vendors, and we exclude anything we cannot independently confirm is real and active in this specific space.

Search demand

Guide priority and the demand figures shown on category pages come from Ahrefs keyword data for the United States. Where we did not pull a reliable figure for a term, we show no number rather than guess one. This is a narrower keyword cluster than some adjacent verticals, so we shipped a small number of guides backed by real, non-trivial buyer-intent volume rather than padding the count.

Vendor sourcing guides

Each guide is buyer education: what the process or vendor covers, what to verify, what to ask in an RFP, and the red flags. Regulatory references (FinCEN, OFAC, FATF, and similar) are named only where they genuinely exist and are current as of publication; this is not legal advice, and current requirements should be verified directly with the issuing agency or your counsel.

What we will not do

• No fabricated credentials, accreditations, case counts, or vendor counts.
• No fake reviews, ratings, testimonials, or fabricated "verified" claims. A paid Verified listing (see Get listed) means KG manually confirmed the business's identity and the accuracy of its own listing facts, nothing more. It is not a customer review, a star rating, a quality score, or an endorsement of the vendor's verification-service quality.
• No Review or AggregateRating structured data, because no real moderated customer reviews exist here.
• No claim that this site itself verifies, certifies, or vouches for any listed vendor, or that any vendor is suitable for your program. That is your call, made with qualified professionals.
