Understanding the ISO 27001 Standard

What Is ISO 27001?

ISO 27001 is the international standard for Information Security Management Systems, published by the International Organisation for Standardisation. It defines the requirements for an information security management system, often shortened to ISMS, and explains how that system should be planned, implemented, operated, monitored, and continually improved so that information security risks are managed in a consistent and structured way.

Rather than acting as a detailed list of technical controls, ISO 27001 sets out what an ISMS must cover and leaves each organisation to select the controls that best fit its risks and obligations. Activ can support this work by providing a place to organise ISO 27001 policies, records, risks, and actions, while the organisation remains fully responsible for its information security decisions.

 

The Meaning and Purpose of ISO 27001

Most people who look up ISO 27001 want to understand what it achieves in practice, not just the formal definition. In simple terms, ISO 27001 helps organisations protect information in a deliberate and organised way, so security stays aligned with their risks and obligations over time.

An ISO 27001 information security management system helps you identify the information assets that matter to your organisation, such as customer data, intellectual property, financial information, or internal systems. It guides you to assess the risks that could affect those assets, select appropriate controls, and put processes in place to manage legal, regulatory, and contractual obligations related to information security.

This structured approach replaces informal or reactive ways of handling security. It encourages clear responsibilities, documented procedures, and regular review. In practice, ISO 27001 is used to build trust with customers, partners, and regulators by showing that information security is managed through a recognised framework rather than through isolated technical measures.

By implementing an ISO 27001 information security management system, organisations can show that they understand their risks, have controls in place, and are committed to continual improvement in how information is protected.

 

ISO 27001 Requirements and Structure

The Benefits of ISO 27001 Certification

The benefits of ISO 27001 certification are both practical and strategic. ISO 27001 certification shows that an independent certification body has audited your information security management system and found that it meets the requirements of the ISO 27001 standard.

One benefit is stronger protection for sensitive and confidential information, because risks are identified and addressed through planned controls rather than informal decisions. Organisations that adopt ISO 27001 often see a reduced likelihood and impact of information security incidents, since responsibilities are clear and processes have been tested and improved over time.

ISO 27001 certification also supports a clearer understanding of information security risks and responsibilities. It provides a framework for aligning information security work with legal, regulatory, and contractual requirements, which can be important in regulated sectors or when working with larger customers.

From a market perspective, ISO 27001 certification can increase trust and confidence from customers, partners, and regulators. It is frequently requested in tenders and supply chains where information security is a key concern. In this way, an effective ISO 27001 information security management system can support both risk management and business development.

 

How to Get ISO 27001 Certification

The journey to ISO 27001 certification usually follows a series of logical steps. Each organisation will have its own context and priorities, but the overall pattern is similar.

The starting point is to understand the ISO 27001 standard and decide the scope of your information security management system. Scope defines which locations, systems, processes, and services the ISMS will cover. Once the scope is clear, you can identify information assets within that scope and define the criteria you will use for assessing information security risk.

You then perform information security risk assessment to identify threats, vulnerabilities, and potential impacts, and carry out risk treatment planning to decide how to address those risks. Based on this work, you select appropriate controls, document policies and procedures, and define how information security will be managed in daily operations.

The next phase is to implement those controls and processes. This includes putting technical and organisational measures in place, raising awareness, and training relevant staff in their information security responsibilities. As the ISMS begins to operate, you monitor performance, record incidents, and run internal audits to check whether the system is working as intended.

Management reviews are used to consider audit results, performance information, and opportunities for improvement. Any nonconformities are addressed through corrective actions. When the ISMS is established and has been running for a period of time, the organisation engages an accredited certification body. The organisation then undergoes a certification audit conducted by that independent body, which assesses whether the ISMS meets ISO 27001 requirements.

 

How Activ Supports ISO 27001

Within Activ you can keep ISO 27001 policies, procedures, records, and evidence together so that they are easy to find and manage. Asset registers and information security risk registers can be maintained in a consistent format, with actions linked to specific risks or controls. This helps create a clear connection between identified risks, chosen treatments, and the work carried out to implement them.

Activ can also be used to track the implementation status of controls against ISO 27001 requirements, so that you can see which areas are fully in place and which still need attention. Incident and nonconformity records can be logged, investigated, and recorded with corrective actions, creating a traceable history of how issues have been handled. 

Supplier and third party information security records, such as due diligence checks or assessments, can be stored alongside other ISMS information. Internal audit schedules, findings, and follow up actions can be managed within the same platform, and dashboards can provide visibility of ISMS tasks and audit readiness.

It sets out requirements for establishing, operating, monitoring, and improving a management system that protects information assets and manages information security risks in a structured way. 

What does an ISO 27001 information security management system include? 

An ISO 27001 information security management system typically includes a defined scope, information security policies, risk assessment and risk treatment processes, documented controls, clear roles and responsibilities, training and awareness activities, incident and nonconformity management, internal audits, and management reviews, all focused on continual improvement of information security. 

What are the benefits of ISO 27001 certification? 

The benefits of ISO 27001 certification include stronger protection for sensitive information, a reduced likelihood and impact of information security incidents, clearer understanding of information security risks and responsibilities, better alignment with legal and contractual requirements, and increased trust from customers and partners, especially in sectors where ISO 27001 is expected in tenders and supply chains. 

How do you get certified to the ISO 27001 standard? 

To get certified to the ISO 27001 standard, an organisation designs and implements an information security management system that meets ISO 27001 requirements, operates it over a period of time with monitoring and internal audits, and then engages an accredited certification body. The organisation undergoes a certification audit conducted by that body, which assesses whether the ISMS conforms to ISO 27001. 

How much does ISO 27001 certification cost? 

The cost of ISO 27001 certification depends on factors such as the size and complexity of the organisation, the number of locations and systems included in the scope, and the time required for the certification body to conduct the audit and ongoing surveillance visits. Internal costs will also reflect the resources devoted to developing, operating, and improving the information security management system.
