ISO 27001

Information Security Management Systems

ISO 27001 is the international standard for managing risks related to the security of information and data your organisation holds. The standard ensures that customer and employee data is stored securely and complies with legal requirements such as GDPR. It adopts a process-based approach for establishing, implementing, operating, monitoring, maintaining, and improving your information security management system (ISMS).

ISO 27001 Certification

  • Achieve ISO 27001 certification through an internationally accredited certification body.
  • Establish secure data transfer and information exchange between organisations.
  • Develop a culture of security at all levels of an organisation to protect sensitive data.
  • Demonstrate compliance with data security legislation such as GDPR.
  • Ideal for organisations of all sizes and sectors that handle personal and commercial data.

What is ISO 27001?

A key priority for organisations is how secure the data and information they hold. With high-profile data breaches and cyber security attacks such as ransomware, customers require organisations to handle, secure and store data and information to the highest standard.

Certification for iso 27001 is the international standard organisations use to implement an information security management system (ISMS). An ISMS allows an organisation to establish data security protocols to manage security risks and comply with relevant legislation such as GDPR.

The standard was developed by the International Organization for Standardization and is part of the wider ISO/IEC 27001 family.

The ISO 27001 standard and ISMS provides a framework for information security management best practice that helps organisations to: 

  • Protect client and employee information.
  • Manage risks to information security effectively.
  • Achieve compliance with the European Union General Data Protection Regulation (EU GDPR) regulations.
  • Protect the company’s reputation and enhance customer trust.
  • Develop and implement objectives in data protection and security.

ISO 27001:2013 has been updated to ISO/IEC 27001:2022!

Since this standard was last updated back in 2013, the information security industry has transformed significantly through the types of new technologies available to us all, such as the cloud.

The level of intellectual property and information assets we hold come with new and emerging threats and risks. This has resulted in the requirement for ISO 27001 to be updated to ensure it stays effective and relevant.

The overall structure of ISO/IEC 27001’s Annex SL clauses have not changed. These clauses include:

  • Clause 4 – Context of the organization
  • Clause 5 – Leadership
  • Clause 6 – Planning
  • Clause 7 – Support
  • Clause 8 – Operation
  • Clause 9 – Performance evaluation
  • Clause 10 – Improvement

The clauses have, however, undergone minor changes including wording, structuring of sentences and some additional new content.

Annex A has had the most significant changes, with the number of controls being refined from 114 in ISO 27001:2013 to 93 in ISO/IEC 27001:2022. These controls have been restructured and merged to align into 4 control sections, instead of the previous 14 sections.

When an organisation is certified to ISO 27001, it means they have controls in place to identify, manage and mitigate risks and have secure systems in place. With cyber-attacks more common than ever, this updated version of the standard offers confidence, assurance and certainty to businesses that their information security management system stays on top of the risks. It also demonstrates to your customers that you take information security seriously and are prepared for any attacks on your system(s).

If your business is currently certified to ISO 27001:2013, you will need to transition to the new standard before the Transition Period Deadline.

There is a transition period of 36 months for certified companies. This runs from 25th October 2022 to 31st October 2025, giving certified companies plenty of time to comply.

Our ISO/IEC 27001:2022 Transition Policy, available for download below, contains useful information to help you through the Transition Period.

We have also created two helpful timeline images available to view below:
