ISO 27001, the international information security standard
What is ISO 27001?
ISO 27001 (ISO/IEC 27001:2013) is the international standard that provides the specification for an information security management system (ISMS).
The Standard is designed to help organisations manage their information security processes in line with international best practice while optimising costs. It is technology and vendor neutral and is applicable to all organisations - irrespective of their size, type or nature.

What is an ISMS?
An ISMS provides a systematic approach to managing information security. It consists of policies, procedures and other controls involving people, processes and technology to help organisations protect and manage all their data.

ISO 27001 and risk management
ISO 27001 emphasises the importance of risk management, which forms the cornerstone of an ISMS. All ISO 27001 projects evolve around an information security risk assessment - a formal, top management-driven process which provides the basis for a set of controls that help to manage information security risks.
By implementing an ISO 27001-compliant ISMS, organisations will be able to secure information in all its forms, increase their resilience to cyber attacks, adapt to evolving security threats and reduce the costs associated with information security.
ISO 27001 clauses and controls
Part of the ISO 27000 family of standards, ISO 27001 consists of 114 controls (from Annex A) and 14 clauses that together support the implementation and maintenance of an ISMS.
ISO/IEC 27001: 2013 management system clauses
- A.5 Information security policies
- A.6 Organisation of information security
- A.7 Human resources security
- A.8 Asset management
- A.9 Access control
- A.10 Cryptography
- A.11 Physical and environmental security
- A.12 Operational security
- A.13 Communications security
- A.14 System acquisition, development and maintenance
- A.15 Supplier relationships
- A.16 Information security incident management
While ISO 27001 offers the specification, the Standard is supported by its code of practice for information security management, ISO/IEC 27002:2013.

ISO 27001 benefits
ISO 27001 is one of the most popular information security standards in the world, with certifications growing by more than 450% in the past ten years. It is recognised globally as a benchmark for good security practice, and enables organisations to achieve independent certification by an accredited certification body following the successful completion of an audit.
ISO 27001 supports compliance with a host of laws, including the EU GDPR (General Data Protection Regulation) and the NIS Regulations (Network and Information Systems Regulations).
Protect your data, wherever it lives
An ISO 27001-compliant ISMS helps protect all forms of information, whether digital, paper-based or in the Cloud.
Meet contractual and regulatory obligations
Certification demonstrates an organisation’s commitment to information security, and provides a valuable credential when tendering for new business.
Reduce costs associated with information security
Thanks to the risk assessment and analysis approach of an ISMS, organisations can reduce costs spent on indiscriminately adding layers of defensive technology that might not work.
Increase your attack resilience
Implementing and maintaining an ISMS will significantly increase your organisation’s resilience to cyber attacks.
Respond to evolving security threats
Constantly adapting to changes both in the environment and inside the organisation, an ISMS reduces the threat of continually evolving risks.
Improve company culture
The Standard’s holistic approach enables employees to readily understand risks and embrace security controls as part of their everyday working practices.
