The most important thing in brief:
- An IT security policy is a binding set of rules that determine how a company protects its IT systems, data and networks — it forms the basis for access controls, incident management and employee awareness.
- Since the NIS 2 Implementation Act came into force in December 2025, documented security guidelines mandatory for over 30,000 companies in Germany — Violations may result in fines of up to 10 million euros and personal liability on the part of the management.
- An effective guideline is not created by copying and pasting a template, but through a structured inventory of your own IT landscape, clear responsibilities and regular review — IT documentation is the indispensable basis for this.
