IT security standards in comparison: ISO 27001, BSI baseline protection, NIS-2 & Co. explained in an understandable way
Whether ISO/IEC 27001, BSI IT-Grundschutz, DIN SPEC 27076, DORA or NIS-2 - each framework pursues its own objectives:
- ISO 27001: internationally recognised, flexible, ideal for customer communication and tenders
- BSI IT Baseline Protection: more in-depth requirements, especially for authorities and KRITIS-relevant companies
- DIN SPEC 27076: ideal introduction for SMEs, practical and resource-saving
- DORA: mandatory for financial service providers, with a high level of maturity
- NIS-2: EU-wide minimum requirement for cyber security - also relevant for many SMEs
IT certifications for SMEs: Why ISO 27001 & BSI baseline protection are worthwhile
ISO 27001 or IT-Grundschutz certification is not an end in itself. It offers:
- An advantage in terms of trust with customers and partners
- Competitive advantages in tenders
- Structured processes for sustainable security
- Better insurability and liability protection
But getting there is challenging: it often takes 6-12 months from the initial analysis and documentation to the audit - depending on the level of maturity and size of the company.
IT security maturity level in SMEs: analysis, stages and optimisation tips
According to Schumann, many SMEs are at maturity level 1 or 2 - processes are ad hoc, documentation is missing, responsibilities are unclear. The aim should be at least level 3: processes in place, clear responsibilities, regular reviews. An external view helps: gap analyses and action plans by specialised consultants create clarity and prioritisation.
