Attestio
About

Built by a consortium of companies
that got tired of the same problem.

Attestio is an independent directory of compliance auditors — PCI QSA, SOC 2, ISO 27001, HITRUST, HIPAA. We index the official lists, add the filters the official lists are missing, and stay out of the way of the relationship between you and the firm you choose to work with.

How it started

We are a consortium of agencies, MSPs, MSSPs, and fractional CISO shops.

Between us, we help dozens of clients navigate PCI DSS, SOC 2, ISO 27001, HITRUST, and HIPAA every year. Which means we spend an unreasonable amount of time helping our clients find the right compliance auditor.

The pain was always the same.

  • → Search the PCI SSC's official QSA list — a PDF with no filtering, no way to find someone who serves your region, no way to see who supports Associate QSA. Just a wall of 419 names.
  • → Cross-reference SOC 2 firms from AICPA, ISO 27001 bodies from the ISO accreditation list, HITRUST AEAs from HITRUST's directory. None of them talk to each other.
  • → Ask peers, get the same 5 recommendations, and discover half of them are at capacity or don't cover your vertical.
  • → Try a lead-gen marketplace. Get a flood of emails, only to learn that the "matches" are sorted by who paid the marketplace most — not who's actually a fit.

After a lot of pain, a lot of late nights, and a lot of "you've got to be kidding me" moments, we built the thing we wished existed.

What we built

An independent directory with the filters the official lists are missing.

We scrape the official lists — PCI SSC, AICPA, HITRUST, ISO — and present them with the filters those lists never had. Region. Service area. Associate QSA support. Languages. Real contact info, not a lead capture form. Updated nightly. Free to browse.

●

Sourced from the source

Every firm is linked back to the official list it came from. We never invent a listing, and we never remove one without a reason.

●

No referral fees, ever

We don't charge buyers. We don't charge per-inquiry. We don't sort results by who paid us. The directory is the same for everyone.

●

Independence is the whole point

Not affiliated with the PCI Security Standards Council, AICPA, ISO, or HITRUST. We just use their public data — the same data they publish for free.

What Attestio is not

The same things we got tired of.

  • × Not a lead-gen marketplace. We don't sell your information. We don't run pay-per-lead auctions. We don't sort results by who paid us the most.
  • × Not a referral network. When you contact a firm, that's your call, and they keep 100% of the engagement. We never see the contract, the invoice, or the audit deliverable.
  • × Not affiliated with any governing body. We are not part of PCI SSC, AICPA, ISO, or HITRUST. We just index their public lists. They don't endorse us, and we don't speak for them.
  • × Not a rating or review site. We don't take reviews from buyers, and we don't take ad money from firms. Verification is the only thing we certify, and it's based on documented proof of certification — not opinions.

What's next

Every vertical with a governing body and an accreditor.

Attestio will eventually cover every compliance vertical that has a governing body and an accreditor.

  • Next SOC 2 — AICPA-licensed CPA firms issuing SOC 2 Type 1 and Type 2
  • Next ISO 27001 — implementation consultants and certification bodies
  • Next HITRUST — Authorized External Assessors (AEAs) for HITRUST CSF
  • Next HIPAA — Security Risk Analysis and audit specialists
  • Later FedRAMP 3PAO, CMMC C3PAO — and the long tail of regional compliance regimes

If you've ever spent 20 hours trying to figure out which audit firm to call, we're building Attestio for you.
