Bottom line: SMEs must examine their opaque, organically grown networks through systematic audits in order to meet NIS2 requirements and reduce liability risks.
Many mid-sized enterprises have grown, opaque IT infrastructures that emerged under cost pressure. With NIS2 and the spread of ransomware attacks, this lack of transparency becomes a calculable business risk that carries direct liability consequences for management.
Typically, SME networks consist of locally connected servers, cloud migrations from various generations and ad-hoc solutions for home office scenarios. This organic growth emerged under time and cost pressure, but follows no overarching strategy. The result is a so-called transparency gap: IT departments often no longer know exactly which devices are active on the network, which cloud services employees use, or how external service providers connect their systems.
This lack of clarity creates security vulnerabilities that remain undetected for a long time. Additionally, there is a vacuum of responsibility at the interfaces between internal teams and external partners. In parallel, complexity hampers productivity: outdated network structures create error-proneness and impede digital transformation. Regulatory pressure is intensifying through NIS2 with binding cybersecurity requirements and personal liability for management. Business partners and customers increasingly demand certified security as a prerequisite for cooperation.
Network audits must therefore not be understood as a bureaucratic obligation, but as a strategic tool for digital resilience. A systematic audit must go beyond the technical IT management level and move directly into the responsibility of management. This enables the transition from reactive to proactive governance and creates the foundation for data sovereignty.
The modern security concept of Zero Trust demands a complete redesign: the notion of a static, externally secured IT environment is obsolete. In decentralized infrastructures with cloud integration, users, systems and data flows must be verified at every point. Such comprehensive control requires fundamental transparency about the existing network architecture.
