How Much Does It Cost to Get ISO27001 with us?

Rachel Gentry: Founder & Managing Director

ISO 27001 certification is a big step for any business wanting to prove its commitment to information security. But in reality one of the first questions most businesses ask is:

"How much will ISO27001 cost?"

The answer? It depends. ISO 27001 costs vary based on several factors, like the size of your company, how mature your security practices are and the sensitivity and risk profile of your data . Let’s break it down.

1. Company Size & Complexity

A small business with 50 employees will spend much less than a multinational with multiple locations. The more systems, staff, and processes involved, the higher the need for extensive audits, larger scope and more resources to manage and maintain your information security compliance.

2. Maturity of your security practices

A highly technical workforce, with high levels of automation and coded policies will require less support than a non-technical service provider. Understanding your in-house expertise is critical to scoping requirements for specialist support or recruitment.

3. Sensitivity and risk profile of your data

Organisations that handle sensitive or highly regulated data will require more stringent controls and demonstrations of compliance. Low risk, or low volumes of sensitive data reduces the level of risk assessment, mitigations and internal audit costs.

4. Using IT & AI to Reduce Costs

With the right tools, businesses can streamline ISO 27001 implementation and reduce costs. But be wary, most tools monitor the compliance of your technology and not the governance, policy or people compliance which are critical elements to obtaining and retaining certification.

🔹 Automated Risk Assessments – AI-powered tools can identify vulnerabilities, recommend controls, and generate risk reports in minutes rather than weeks.🔹 Compliance Management Platforms – IT solutions help track progress, manage documentation, and automate reporting to reduce admin time.🔹 AI-Driven Internal Audits – AI tools can flag gaps in security controls, ensuring faster, more accurate compliance checks.🔹 Security Information & Event Management (SIEM) Systems – These tools automate security monitoring, helping businesses meet ISO 27001 requirements without hiring additional staff.

5. Technology & Security Investments

Some companies already have solid security in place, while others need to invest in new tools (like firewalls, security monitoring, or access control systems) to meet ISO 27001 requirements.

6. Training & Awareness

ISO 27001 requires staff awareness training. If you don’t have an internal trainer, you'll need external courses.

7. Certification & Audit Costs

To officially get certified, you’ll need an accredited certification body to audit your business. This includes:✔️ Stage 1 Audit – Checks documentation & readiness.✔️ Stage 2 Audit – Full assessment to confirm compliance.✔️ Surveillance Audits – Ongoing yearly checks to maintain certification.

8. Ongoing Compliance & Maintenance

ISO 27001 isn’t a one-time thing. You’ll need to keep running internal audits, updating policies, and improving security. Achieving ISO27001 is often the easy part - maintaining compliance for the annual surveillance audits and three-year re-certification can prove much more difficult.

So, How Much Will ISO27001 Cost You?

The cost of ISO 27001 depends on your business size, scope, existing security, and risk profile of your data. For most small-medium businesses, expect to budget at least £10,000 – £80,000 for full certification.

Want to keep costs down?✔️ Use IT & AI tools to automate compliance.✔️ Start with a gap analysis before full certification.✔️ Consider a structured, step-by-step approach instead of rushing the process.
