- Technical complexity of the ISMS: The complexity of the ISMS depends on the type of data processed, the technologies used, and the integrated security measures.
- Number of employees: Companies with a larger number of employees typically have more extensive information systems and processes.
- Number of locations: The number of locations plays a significant role in audit costs. Each location usually needs to be audited individually.
ISO 27001 Certification Costs: Based on our current daily rates, you can expect costs starting from €4,725 for ISO 27001 certification if your company has 9-10 employees. Please note that this estimate may vary, and a more accurate assessment will be provided after receiving your specific information.
- The company must conduct a thorough risk assessment.
- There must be a clear ISMS policy.
- Scope of the ISMS: The company must precisely define the scope of the ISMS.
- Implementation of appropriate security controls (from Annex A of ISO 27001 or other sources) aligned with the results of the risk assessment.
- Internal auditing.
- Management review.
- Continuous improvement: A process for continuous improvement of the ISMS must be implemented.

- ISO 9001 (Quality Management)
- ISO 14001 (Environmental Management)
- ISO 45001 (Occupational Health and Safety)
- ISO 50001 (Energy Management)
