What is ISO 27001?

ISO/IEC 27001 is the leading international standard for information security management systems (ISMS). Worldwide, organisations implement and maintain an ISMS to

  • Protect data that is crucial to the business
  • Mitigate risk and ensure stable operations
  • Provide confidence to stakeholders and customers


The ISMS standard offers a well-proven framework to help companies increase information security levels whilst improving cost-efficiencies. Watch the video to learn more about the benefits of an ISMS based on ISO/IEC 27001.

Manage information security risk

The ISO/IEC 27001 standard outlines a risk management process involving people, processes and IT systems, thereby providing a holistic approach to information security. The video below gives a step-by-step introduction to the principles of risk management according to the ISMS standard and can serve as a helpful guideline for the implementation of your infosec system.

ISO/IEC 27001 is an internationally recognised standard, published by the International Organisation for Standardization (ISO) and the International Electrotechnical Commission (IEC). The standard specifies the requirements for implementing and maintaining an effective ISMS to protect against the root causes of information security risks. Organisations that achieve ISO/IEC 27001 certification strengthen their ability to protect themselves against cyberattacks and help prevent unwanted access to sensitive or confidential information. The scope of ISO/IEC 27001 is intended to cover all types of information, regardless of its form.


Certification to ISO/IEC 27001 can represent an important step in an organisation’s efforts to protect its IT infrastructure and to secure digitised data in its possession.

  • What are the requirements for ISO 27001 certification?

    Understanding the context of the organisation and the requirements of the interested parties forms the basis of the ISMS implementation. Information security risk would need to be identified and mitigated with the applicable controls in Annex A to ensure that information assets are protected and commensurate to the risk levels and risk appetite.

    As in all management systems, objectives have to be identified, measured and monitored. Policies, procedures, processesand records would have to be documented to demonstrate the effective implementation of the ISMS.

    In line with ISO/IEC 27006 and accreditation requirements, the cost depends on, among others, the number of employees, IT complexity and the number of sites. For an estimated cost, contact us.
