How much does ISO 27001 certification actually cost?

The number most companies see first

Ask a consulting firm for a quote. You'll get something between $60,000 and $150,000.

That's real. That's not inflated for negotiation room (well, sometimes it is, but the floor is genuinely high). A full ISO 27001 consulting engagement for an SMB involves scoping, gap analysis, documentation development, internal audit support, and audit preparation — typically 300 to 600 hours of work.

At $150 to $250 per hour for experienced consultants, the math lands where it lands.

What's actually driving the cost

Breaking it down:

Gap analysis — A qualified consultant audits your current security practices against ISO 27001 requirements and produces a findings report. 20 to 40 hours. $3,000–$8,000.

Documentation development — Your ISMS documentation: policies, procedures, risk register, Statement of Applicability, and all supporting documents. This is the bulk of the work. 100 to 300 hours depending on your scope and existing documentation state.

Risk assessment facilitation — Running workshops with your team, building the risk register, getting leadership buy-in on the risk treatment plan. 20 to 60 hours.

Internal audit — Before your external certification audit, a qualified internal audit needs to happen. Consultants either run this themselves or help you run it. 20 to 40 hours.

Audit preparation — Organizing documents, prepping your team for auditor interviews, mock runs. 10 to 20 hours.

Add it up, and a real engagement is 200 to 500 hours before you account for project management overhead, revisions, and the inevitable scope expansion.

The internal hire alternative

Some companies try to hire their way out of the problem. A dedicated GRC Analyst focused on ISO 27001 can work. But the math is still significant.

• Salary: $80,000 to $110,000 per year
• Benefits and overhead: add 30 to 40 percent
• Fully-loaded cost year one: $104,000 to $154,000

And that's before accounting for the fact that a new hire takes six to twelve months to understand your environment before they're producing useful work.

Template packs

There are several well-known template libraries. Prices range from £299 to $2,000 depending on the provider and what's included.

These are useful — having a starting point for your documentation is genuinely valuable. The gap is guidance: what to fill in, what order to do things, what auditors actually look for versus what looks thorough but doesn't matter.

Most teams that buy template packs spend six months adapting documents without a clear sense of whether they're building the right thing in the right way.

The structured course option

ISMS Accelerator sits between the template pack and the consulting firm.

DIY — $1,497: Full 11-module course, 40+ templates, lifetime access. For teams that can self-direct through a structured program.

Guided — $3,997: Everything above plus 12 months of group coaching calls and a certification guarantee. For teams that need check-ins and want someone watching their back through the implementation.

Done-With-You — $12,000: Everything above plus six private 1-on-1 sessions, document review, and a mock internal audit. The closest thing to a consulting engagement at a fraction of the price.

One more cost to factor in

The certification audit itself — the exam, so to speak — is separate. You pay the certification body directly.

Typical range for SMBs: $5,000 to $15,000. Variables include company size, scope, certification body selection, and whether Stage 1 reveals issues that require a second visit.

Module 9 covers how to select a certification body and what to ask before signing a contract.

What the gap actually looks like

For a 60-person SaaS company with a 12-month target:

| Option | Total year 1 cost | |--------|------------------| | Consulting firm | $75,000–$120,000 | | Internal GRC hire | $100,000–$140,000 | | Template pack | $2,000 (plus 12+ months, uncertain outcome) | | ISMS Accelerator Guided | $3,997 + audit fees ($5,000–$10,000) |
