Among the 95 directory firms whose AICPA peer-review result is public (a member/opt-in subset, not the whole directory), the results break down as recorded; we do not extrapolate this to firms that do not disclose.

We counted 4,861 active IT-audit job postings on company career sites across the US, UK, and Canada in 2026-06.
Source: SOC 2 Auditors, https://soc2auditors.org/data/#it-audit-job-postings-total (retrieved 2026-06-11). Across audit and compliance roles, IT audit is the most common (4,861). Dedicated "SOC 2 auditor" titles are rare (2); demand surfaces as the broader roles. These are separate keyword searches with overlapping coverage, so we compare them rather than add them up.

The internal figures on this page are computed from our directory of 182 SOC 2 audit firms. Cost and timeline figures use each firm's published range midpoint; we report the median (p50) and, where stated, the 10th to 90th percentile band, so eight in ten firms fall inside it. Counts and shares are simple tallies over the same dataset. A firm missing a field is excluded from that figure's sample, never counted as a zero.
Our pricing figures are public-records estimates, not firm-confirmed quotes. They describe what firms publish and what the market reports, not a binding price for any engagement. A CPA firm sets the final fee after scoping your systems. Treat every number here as a planning aggregate with a known method, dated so you can judge how current it is.
The original June trust-page adoption series has been withdrawn from the public roll-up. Its regex could not reliably distinguish a company's own attestation from a vendor claim, and blocked pages could be counted as absent. The replacement attested-company index will publish only after a stratified 200-page calibration set is complete; until then, no adoption or platform-share figure is shown.
The audit-firm figures join US firms in our directory to the AICPA public peer-review file search. Enrollment is reported over the full matched US directory sample. Ratings are reported only for the member or opt-in subset whose result is public; we do not extrapolate those disclosed results to firms that do not disclose.
The hiring figures are a demand proxy, not a SOC 2 headcount. We aggregate from a public job-postings index that crawls companies' own applicant-tracking-system career sites and matches title and department tokens. We compare separate role searches rather than summing them because their coverage can overlap, and the headline count uses IT audit alone across the US, UK, and Canada.
We refresh this dataset monthly. It was last computed on 2026-07-01; the next refresh is planned for 2026-07-13. Each figure carries its own computed date in case a single series moves between refreshes.
