ISO 27001 pricing report 2026
Every published ISO 27001 cost figure we could verify, with the source named in every row. No invented averages, no "typical" figures without a citation.
Across six published 2026 sources: Stage 1 + Stage 2 audit fees cluster around $8,000–$25,000 for small-to-mid companies; SMB first-year all-in costs run $15,000–$50,000; annual surveillance runs $4,000–$10,000. Audit-day rates: $1,500–$2,200/day (US), £1,000–£1,500/day (UK). Currency and market differences explain much of the spread — compare like with like.

What we deliberately did not publish
- No "average ISO 27001 cost." Markets, currencies, and scopes differ too much; an average would be a fiction.
- No per-CB pricing. CBs price per engagement; any per-CB number we published would be invented.
- No year-over-year trend line. We have one solid vintage (2026); a trend needs at least two.
How to use this report. Use these ranges to budget and to sanity-check CB quotes (see how audit fees are calculated). Your actual fee comes from a scoped quote — get 2–3 and compare.
