This is the ISO 27001 certification:

It’s a testament to your organization’s commitment to data security. More than that, For your clients, it’s proof that their data is in safe hands.

But how exactly can a company become ISO 27001 certified? What are the steps involved, and what requirements must be met? In this guide, we’ll walk you through the process of achieving ISO 27001 certification, explaining each stage in detail—from planning to audits.

Understanding ISO 27001 certification and its benefits

ISO 27001 is an international standard for an Information Security Management System (ISMS). It provides a framework for organizations to manage their data security risks effectively. The certification shows that a company adheres to best practices for data protection, confidentiality, and availability.

Becoming ISO 27001 certified comes with multiple benefits:

• Enhanced data security: ISO 27001 helps organizations implement strong controls to prevent data breaches and leaks, reducing the risk of cyberattacks.
• Compliance: Many businesses need to comply with regulatory standards. Achieving ISO 27001 certification can simplify this process by providing a recognized compliance framework.
• Customer trust: Certification reassures clients and partners that their sensitive data will be handled securely, increasing confidence in your business.
• Competitive edge: ISO 27001 certification sets you apart from competitors who may not prioritize data security. This gives your company an edge, especially when dealing with clients who require strict security measures.
• Operational efficiency: By implementing the processes required by ISO 27001, companies often find themselves running more efficiently, reducing redundancies, and improving overall performance.

💡 It’s important to understand the difference between ISO 27001 vs. 27002. While ISO 27001 provides the requirements for establishing, implementing, maintaining, and continually improving an ISMS, ISO 27002 offers guidance on the controls outlined in ISO 27001.

Requirements for ISO 27001 certification

Achieving ISO 27001 certification is not just about passing an audit—it’s about building a robust Information Security Management System (ISMS) that continually protects your organization’s assets. The ISO 27001 standard outlines several key requirements that businesses must meet to become certified. 

Management commitment

One of the primary pillars of ISO 27001 is strong, visible leadership from senior management. The success of your ISMS hinges on the commitment of your organization’s leadership team.

This requirement includes:

• Establishing and approving the information security policy.
• Providing necessary resources, such as tools, personnel, and technology, to support the ISMS.
• Demonstrating an ongoing commitment to maintaining and improving the ISMS, which includes participating in periodic management reviews.
• Ensuring that information security objectives are aligned with the organization’s broader strategic goals.

Without visible commitment from top management, it’s unlikely that the ISMS will be effectively implemented or maintained over time. Leadership involvement is essential to foster a security culture across all levels of the organization.

Risk assessment

At the heart of ISO 27001 is risk management. The standard requires organizations to carry out a comprehensive risk assessment to identify potential threats and vulnerabilities to their information assets.

The goal is to determine where risks exist, assess the potential impact, and establish a risk treatment plan to mitigate or manage those risks.

Risk assessment steps include:

1. Identification of risks related to information assets, such as data breaches, hardware failures, or unauthorized access.
2. Analysis of the likelihood and impact of each identified risk. This involves quantifying both the probability of a risk occurring and its potential consequences.
3. Evaluation to determine which risks are acceptable and which require action. Risks may be accepted, transferred (e.g., via insurance), or mitigated by implementing security controls.

After the assessment, the organization develops a statement of applicability (SoA), which lists all the controls selected to mitigate these risks. This SoA is a critical document in the certification process, as it defines the security measures your organization will put in place.

Security policy

An organization’s information security policy is the blueprint for its approach to protecting information. This document outlines the organization’s security objectives, responsibilities, and how it intends to manage security threats.

Key elements of a security policy include:

• Scope: Defines which parts of the organization are covered by the policy (e.g., specific departments or the entire company).
• Responsibilities: Outlines roles and responsibilities for information security within the organization.
• Risk Management: Describes the risk management process, including risk assessment, risk treatment, and ongoing risk monitoring.
• Security Objectives: Clearly states the organization’s objectives for protecting information and maintaining security.

The policy must be communicated throughout the organization, ensuring all employees understand their roles in maintaining information security.

Asset management

Knowing what you’re protecting is fundamental to security. Asset management is the process of identifying and categorizing information assets, such as data, hardware, software, and intellectual property. Each asset must be assessed for its value to the organization and the level of protection required to safeguard it.

The steps in asset management include:

• Inventory of assets: Create a comprehensive list of all assets within the organization. This includes data, databases, laptops, mobile devices, and software systems.
• Ownership assignment: Every asset must have an assigned owner responsible for its security. This ensures accountability for the protection and proper use of the asset.
• Classification: Assets should be classified based on their value, criticality, and sensitivity. For example, highly sensitive customer data may require more stringent security controls than less critical assets.
• Handling and protection: Develop specific handling procedures for different asset types. This might include encryption for sensitive data or regular backups for critical business information.

Effective asset management ensures that all valuable assets are accounted for, classified according to their importance, and protected accordingly.

Implementing controls

ISO 27001 outlines a broad range of security controls that must be implemented to mitigate risks identified during the risk assessment process. These controls are outlined in Annex A of the standard, and they cover a variety of areas including access control, cryptography, and incident management.

The controls can be divided into three main categories:

• Preventive controls: These are designed to prevent security incidents from occurring. Examples include firewalls, anti-virus software, and physical security measures such as locks or biometric scanners.
• Detective controls: These controls help detect security incidents when they happen. This could include monitoring systems, log analysis, or intrusion detection systems.
• Corrective controls: Corrective measures help organizations respond to and recover from security incidents. These might include incident response plans, disaster recovery plans, or regular backups.

Each organization must select the controls that are most relevant to its operations and risk profile, as detailed in the statement of applicability.

Internal audits

Internal audits are a critical part of maintaining the ISO 27001 certification. These audits are conducted to ensure the ISMS is functioning as intended and to identify areas for improvement.

The internal audit process typically includes:

• Planning the audit: Defining the scope, objectives, and methodology of the audit.
• Conducting the audit: Examining records, interviewing personnel, and reviewing processes to evaluate compliance with the ISMS.
• Reporting results: Documenting findings, including any non-conformities or areas where controls may need improvement.
• Taking corrective action: Addressing any issues identified during the audit to ensure ongoing compliance.

Internal audits are not a one-time process; they must be conducted regularly to ensure that the ISMS remains effective and compliant with ISO 27001.

Steps to getting ISO 27001 certification

Now that we’ve covered the requirements, let’s walk through the step-by-step process to implement ISO 27001 and achieve certification. Each step is crucial to ensuring your ISMS is both effective and compliant with the standard.

1. Planning and preparation

The first step in any certification journey is planning. This includes setting clear objectives for why your organization is seeking certification, determining the scope of the ISMS, and identifying which departments or processes it will cover. Additionally, assembling a cross-functional team to lead the implementation is critical for success.

2. Performing a gap analysis

A gap analysis is a crucial step in identifying any areas where your company does not yet meet ISO 27001 requirements. This analysis compares your current security practices to the ISO 27001 standard, highlighting areas that need improvement. Once gaps are identified, your team can begin addressing these issues.

3. Implementing the management system

With your plan in place and gaps identified, the next step is to implement the management system. This involves creating and deploying the necessary policies, procedures, and controls to manage information security risks. The implementation stage is often the most time-consuming but essential for ensuring long-term security and compliance.

During this phase, you’ll focus on:

• Creating an information security policy.
• Implementing controls as outlined in ISO 27001 controls.
• Documenting procedures and responsibilities for security management.

4. Conducting internal audits

Once the ISMS has been implemented, your organization must conduct internal audits to ensure it meets the ISO 27001 standard. These audits are typically performed by internal teams or third-party consultants who will review your ISMS for compliance. Any non-conformities identified during the audit should be corrected before proceeding to the certification audit.

5. Management review

After internal audits, management must perform a formal review of the ISMS. This step involves assessing the system’s performance, addressing any issues raised during internal audits, and ensuring that the ISMS remains aligned with business objectives. This management review demonstrates the company’s commitment to continual improvement.

6. Certification audit

The certification process involves a stage 2 audit, where an independent certification body evaluates your ISMS. The audit will assess whether your organization has implemented the required controls and is compliant with ISO 27001 standards. If successful, you will receive your certification, proving your organization’s commitment to data security.

7. Surveillance audits

Even after certification, the journey doesn’t end. Organizations must undergo surveillance audits periodically to ensure that the ISMS is maintained and continually improved. These audits are conducted by the certification body and focus on ensuring compliance with the standard over time.
