ISO 27001 Certification Guide: What You Need to Know

What is ISO 27001 certification?

ISO 27001 is an international standard that specifies the requirements for an ISMS (information security management system). An ISMS is a framework of policies, processes and procedures that helps an organisation manage its information security risks.

ISO 27001 certification provides independent, third-party verification that an organisation’s ISMS meets the requirements of the ISO 27001 standard. Certification is granted by an accredited certification body following a successful audit of the organisation’s ISMS.

Organisations that are certified to ISO 27001 can use the certification to demonstrate to their customers and other stakeholders that they have implemented an ISMS that meets international best practice.

Once certification is achieved, it is valid for three years. However, the ISMS must be managed and maintained throughout that period. Auditors from the certification body will conduct annual surveillance visits while the certification is valid.

How to get ISO 27001 certification

To achieve ISO 27001 certification, an organisation must first develop and implement an ISMS that meets all the requirements of the Standard. Once the ISMS is in place, the organisation can then register for certification with an accredited certification body.

The certification body will carry out an audit of the ISMS to ensure it meets the requirements of ISO 27001. If the ISMS is found to be compliant, the certification body will issue an ISO 27001 certificate.

How to prepare for ISO 27001 certification

There is no one-size-fits-all answer to this question, as the amount of preparation required will vary depending on the size and complexity of your organisation, as well as your current level of compliance with the Standard. However, some tips on how to prepare for ISO 27001 certification include the following:

  1. Perform a gap analysis to identify any areas where your organisation does not meet the requirements of the Standard.
  2. Develop an implementation plan that outlines how you will close any gaps identified in the gap analysis.
  3. Train your staff on the requirements of the Standard and on your implementation plan.
  4. Create or update your organisation’s ISMS documentation, including policies, procedures, and other supporting documents.
  5. Conduct internal audits to verify that your ISMS is functioning as intended and that all employees are following the required procedures.
  6. Schedule and complete an external certification audit with a certification body.

The ISO 27001 certification process

Once you are ready for certification, you will need to engage the services of an independent, accredited certification body. These certification bodies have been assessed by the relevant national authority based on their competence, impartiality and performance capability through a rigorous assessment process.

The ISO 27001 accreditation process consists of two stages and is conducted by a qualified auditor.

Stage 1

The auditor will review your documentation to check that the ISMS has been developed in accordance with the Standard. You will be expected to present evidence of all critical aspects of the ISMS, but how much depends on the certification body’s requirements.

Stage 2

If you pass the first stage, the auditor will conduct a more thorough assessment. This assessment will involve reviewing the activities that support the development of the ISMS. The auditor will analyse your policies and procedures in greater depth and check how the ISMS works in practice with an on-site investigation. The auditor will also interview key staff members to verify that all activities are undertaken following the specifications of ISO 27001.

How much does ISO 27001 certification cost?

The cost of ISO 27001 certification usually depends on the number of employees working for the organisation. Certification for an organisation with up to 500 employees could cost in the region of £10,450.

Can you get certified to ISO 27001 with IT Governance?

We support the concept of independent, accredited certification, which means that we do not audit our own work. For the same reason, certification bodies are not permitted to provide consultancy and advice to their clients before conducting a certification audit.

Through our years of experience assisting more than 600 organisations with ISO 27001 implementation and certification projects, we know precisely what certification bodies expect. As a result, we can offer you unrivalled expertise.
