What is iso 27001?

ISO/IEC 27001 is an internationally recognized standard published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It outlines the requirements for implementing and maintaining an effective Information Security Management System (ISMS) to protect against the root causes of information security risks, covering all types of information in various forms such as digitized data, documents, electronic communications, and recordings. Organizations that achieve ISO/IEC 27001 certification enhance their ability to protect against cyberattacks and prevent unauthorized access to sensitive or confidential information.

WHY IS ISO 27001 important

Information security is crucial in today's digital world where organizations face increasing cyber threats and risks of data breaches. ISO 27001 certification demonstrates an organization's commitment to information security best practices and provides assurance to customers, partners, and stakeholders that appropriate measures are in place to protect sensitive information. ISO 27001 helps organizations establish a robust ISMS that can effectively mitigate information security risks, safeguarding the confidentiality, integrity, and availability of information assets.

Benefits of ISO 27001:

  • Enhanced Information Security: ISO 27001 certification helps organizations establish a robust ISMS, which results in improved information security posture and reduced risk of data breaches.
  • Customer Confidence: ISO 27001 certification provides assurance to customers that an organization has implemented adequate information security measures, enhancing their confidence in the organization's ability to protect their data.
  • Competitive Advantage: ISO 27001 certification sets organizations apart from competitors by demonstrating their commitment to information security, which can lead to increased business opportunities.
  • Compliance: ISO 27001 helps organizations comply with legal and regulatory requirements related to information security, reducing the risk of penalties and fines.

The international rules we are obliged to follow as a certification body are constantly reviewed and monitored by the respective committees. This process resulted in an amendment of ISO/IEC 27006, which is the relevant standard for certifying ISO/IEC 27001, published in March 2020. As result, TÜV SÜD Management Service GmbH must implement the rules given in this amendment by end of March 2022, including a verification by our accreditation body, Deutsche Akkreditierungsstelle GmbH. TÜV SÜD Management Service GmbH strives to finalize this change as fast as possible. Part of the requirements for implementing the amendment is to inform existing customers about this change.

The requirements for your information security management system do not change with this amendment, only the internal processes of the certification body are affected.


  • What is the difference between ISO 27001 and SOC 2?

    ISO 27001 (applicable for organizations of any size or industry internationally) is a standard that establishes requirements for an Information Security Management System (ISMS) and SOC 2 (applicable for service organizations in any industry in the United States) refers to a set of audit reports to evidence the level of conformity to a set of defined criteria (TSC). ISO 27001 is designed to define, implement, operate, control, and improve overall security, while SOC 2 is intended to prove security level of systems against static principles and criteria.

  • When is ISO 27001 certification required?

    Companies who use data handling or technology services often require their providers to be ISO 27001 certified so that they are compliant with the EU’s GDPR (General Data Protection Regulation).

  • Who needs to be ISO 27001 certified?

    ISO 27001 can be required in any sector where data confidentiality is critical, for example: healthcare, banking, HR, etc.

  • How long is an ISO 27001 certification valid?
