How much does ISO 27001 certification cost?
The short answer
ISO 27001 certification has two kinds of cost: getting your own people ready, and paying a certification body to audit you. Training is the part you can price today. With Cybrainer, the ISO/IEC 27001 Lead Implementer and Lead Auditor courses cost $600 per person each, and the price includes the PECB certification exam. Certification body fees depend on your headcount and scope, so ask two or three accredited bodies for a quote.
What does ISO 27001 training cost?
- ISMS owner or project lead: ISO/IEC 27001 Lead Implementer, $600. They learn to scope, build and run the ISMS.
- Internal auditor: ISO/IEC 27001 Lead Auditor, $600. They learn to run the yearly internal audit that clause 9.2 requires.
- Risk owner (optional): ISO/IEC 27005 Risk Manager, $600. They learn to run the risk assessment that decides which controls you need.
Every course includes the PECB certification exam, practice questions and the training material.
What does a typical training budget look like?
- $600: one person trained as Lead Implementer builds and runs the ISMS. This works for a small scope, with internal audits bought in from outside.
- $1,200: a Lead Implementer to build the ISMS and a separate Lead Auditor to audit it. Two people are needed because an auditor should not audit their own work.
- $1,800: the same two people plus a Risk Manager for the risk assessment, which is where many first-time projects get stuck.
What else does certification cost?
- Implementation time: scoping, risk assessment, the Statement of Applicability, policies and putting controls in place, in the months before the audit.
- Certification audit: Stage 1 checks your documents and readiness, and Stage 2 checks that the controls work in practice. Both happen in year 1.
- Surveillance audits: a shorter audit by the certification body in years 2 and 3.
- Recertification: a full audit to renew the certificate in year 3.
- Tools: ISMS or GRC software, plus security tooling for missing controls. Both are optional.
Implementation time is usually the biggest cost. It falls when someone inside the company already knows how to build an ISMS, which is the point of training a Lead Implementer instead of hiring a consultant for the whole project.
Why do certification audit quotes vary?
Certification bodies estimate the number of auditor days and multiply it by their day rate. The days come from accreditation rules (ISO/IEC 27006), which start from the number of people working under your ISMS. The estimate then goes up or down with the number of sites, your IT setup and how much you outsource.
Ask each body to state its audit days for Stage 1, Stage 2 and each surveillance audit, so you can compare quotes directly.
How can I keep the total down?
- Narrow the scope. Certify the product or business unit your customers ask about, not the whole group.
- Train your own people. A trained ISMS owner and internal auditor replace much of the consultancy time.
- Reuse what you have. Many Annex A controls overlap with SOC 2, NIS2 and the customer security questionnaires you already answer.
How long does it take?
Most of the time goes into implementation, not the audit. The ISMS has to run for a while before Stage 2, so the auditor can see records such as risk treatment, internal audit results and a management review.
Is ISO 27001 worth the cost?
For companies that sell to enterprises or the public sector, often yes. The certificate replaces many custom security questionnaires and is often required in tenders. It also gives you a working base for NIS2, DORA and GDPR security obligations.
