How much does ISO 27001 certification cost in 2025?

Achieving ISO 27001 certification is more than just ticking a compliance checkbox; it's a testament to your organization's commitment to protecting sensitive information and building trust with stakeholders. This globally recognized standard provides a robust framework for implementing an Information Security Management System (ISMS) to safeguard data. Certification demonstrates a proactive approach to cybersecurity risks, boosting customer confidence and aiding regulatory alignment.

The cost of weak information security practices can be steep—ranging from reputational damage to financial penalties if a security breach occurs. Certification to ISO 27001 demonstrates a proactive approach to mitigating these risks. The average cost of obtaining ISO 27001 certification varies but typically ranges between $15,000 and $60,000, depending on factors like company size, scope, and readiness for the audit. Additional costs may include ongoing maintenance, internal resource allocation, and potential non-recurring consultancy services.

Methods to achieve ISO 27001 standard certification and their costs

When pursuing ISO 27001 certification, organizations can choose from several methods based on their resources, expertise, and scope. Each method has its own costs and benefits, which depend on the level of external support and organizational readiness.

1. Do-it-yourself (DIY) approach

This method is suitable for organizations with in-house expertise in information security and compliance. Internal teams manage the entire certification process, including gap analysis, ISMS implementation, and audit preparation.

• Cost: Typically low, as most expenses are tied to internal resources and certification body fees. Expect costs between $5,000 and $15,000 for smaller organizations.
• Best for: Companies with skilled teams familiar with ISO 27001 requirements.
• Drawback: Time-intensive and prone to errors without external guidance.

2. Consultant-assisted certification

In this approach, organizations hire external ISO 27001 consultants to guide the implementation process. Consultants offer expertise in risk assessment, control implementation, and audit preparation.

• Cost: Moderate to high, depending on the consultant's experience and scope of involvement. Costs can range from $15,000 to $40,000.
• Best for: Mid-sized companies needing guidance but maintaining some in-house effort.
• Drawback: Dependency on external experts can be costly.

3. Turnkey solution

This method involves outsourcing the entire certification process to a third-party service provider. These providers handle end-to-end implementation, including documentation, ISMS deployment, and audit coordination.

• Cost: High, ranging from $30,000 to $60,000 or more, depending on the scope and provider.
• Best for: Large organizations or those with no prior experience in ISO 27001.
• Drawback: High costs and reliance on external control.

4. Automated compliance platforms

Modern compliance tools like Scrut simplify ISO 27001 implementation through automated workflows, document management, and control tracking. These platforms often include templates and real-time compliance monitoring.

• Cost: Subscription fees typically range between $5,000 and $20,000 annually, depending on the platform and features.
• Best for: Tech-savvy organizations looking for efficiency and scalability. Such platforms also offer consolidated compliance for other frameworks/standards like GDPR, ISO 42001, SOC 2, and more.
• Drawback: Requires initial training to utilize the platform effectively.

Choosing the right method depends on your organization's size, expertise, and budget.
