Overview: ISO 27001:2022

• A globally recognised standard for clear structures in a modern Information Security Management System (ISMS)
• Since the 2022 update, it focuses even more on cybersecurity, data protection, and streamlined controls
• Combines technical security measures with data-driven Human Risk Management
• Ensures long-term compliance and optimises processes through regular audits
• A signal of trustworthy handling of sensitive data to customers and partners

What is ISO 27001?

ISO 27001 simply explained: It is the internationally leading standard for information security in private and public organisations. It not only describes technical measures but also requires the establishment of a holistic Information Security Management System (ISMS).

Having evolved over time, the standard was developed to protect the confidentiality, integrity, and availability of information. The correct terminology is important for your current strategy: while often shortened to ‘27001’, the full designation of the current version is ISO/IEC 27001:2022. The “IEC” stands for the International Electrotechnical Commission, which publishes the standard jointly with the ISO.

For managers, an ISO 27001 summary offers one key insight: it is no longer just about IT security in the server room, but about information security as a company-wide process. The standard acts as a stable enterprise security framework that actively manages risks. Unlike, for example, the NIST CSF 2.0, which focuses heavily on response and recovery, ISO 27001 offers the best structure for certification and ongoing management.

ISO 27001 Benefits: The Advantages of the 2022 Version

The update to the standard brings tangible benefits for companies that go far beyond a mere compliance exercise. The ISO 27001 benefits can be used strategically to argue the case to the board of directors or supervisory board:

• The streamlined set of controls makes practical application less bureaucratic. This reduces operational overhead and makes the ISMS more manageable.
• Companies can pool resources where risks are greatest, instead of stubbornly working through checklists. This risk-based approach saves budget and time.
• The DIN ISO/IEC 27001:2022 requires a stronger alignment of security objectives with actual business goals and stakeholder expectations. Security thus becomes an enabler for new business models.
• Security is no longer isolated as a pure IT topic, but integrated into existing processes as a strategic requirement. This strengthens trust in the supply chain (supply chain security), which is increasingly important in light of regulations such as NIS2 (Who is affected?) is becoming ever more important.

Changes: ISO 27001:2013 vs. 2022 in Comparison

The comparison between ISO 27001:2013 and 2022 shows that the standard has become more modern and modular. The most obvious change can be found in the title of the standard itself: “Information technology” has become “Information security, cybersecurity and privacy protection”. The ISO thus explicitly requires that IT security, data protection, and company-wide crisis defence be managed as a single system. In addition, governance structures and risk management have been refined.

Focus on the Controls

The ISO 27001 controls in Annex A are particularly relevant for operational implementation.

• The number of controls has been reduced from 114 to 93.
• Instead of 14 domains, there are now only four topic areas:
  1. Organisational
  2. People
  3. Physical
  4. Technological

With these new ISO 27001:2022 controls, responsibilities in the ISMS can be assigned much more directly.

ISO 27001 Requirements: What Companies Must Fulfil

What specific ISO 27001 requirements will your company face?

Ensuring ISO 27001 Audit & Compliance

The path to certification and its maintenance involves regular reviews.

Audits as a Reality Check

It’s not just the external certification audits that are relevant. Actively manage your ISMS through internal audits to uncover weaknesses long before the external auditor comes knocking. The auditor requires proof that your employees know and understand existing risks (effectiveness). This is where your cybersecurity awareness training provides the necessary data points: instead of just presenting attendance lists, you can prove that the theoretical knowledge from the policies is also applied in everyday work and that the risk has been genuinely reduced.

Ensuring Compliance

To achieve long-term ISO 27001 compliance, technical and human risks must be addressed equally. The management review (Chapter 9.3) serves as a strategic lever to secure budget and resources based on audit data. Modern approaches such as Human Risk Management precisely measure behavioural changes and thus secure your ISO 27001 compliance far beyond the audit.

Implementation: From the Catalogue of Measures to Certification

A successful ISO 27001:2022 implementation can be broken down into seven generic steps that bring structure to the complex project:

1. Define Scope
   Define the scope of the ISMS. A scope that is too broad unnecessarily increases complexity.
2. Leadership Commitment
   Management must provide resources and enforce the security policy.
3. Risk Assessment
   Identify assets and threats. Here, a data-driven Human Risk Management Platform helps to identify and prioritise particularly vulnerable departments (“human risk”).
4. Define Measures
   Select the appropriate controls from Annex A. Many companies also use the prioritised CIS Controls or the COBIT framework for IT governance to tailor the Statement of Applicability (SoA) even more precisely to operational risks.
5. Awareness & Competence
   Train your workforce.
6. Internal Audit
   Independently check the effectiveness of the measures through independent internal auditors.
7. Certification Audit
   The two-stage audit by an accredited body.

To make it easier for you to get started, the following table shows how the ISO 27001:2022 catalogue of measures can be scaled depending on the size of the company, including tips for ISO 27001 for small companies.

A successful certification according to ISO 27001 ultimately proves that you manage information security holistically. When you prioritise technological measures and the human factor equally, the initial compliance requirement becomes a strategic driver for your company-wide resilience.
