Management Liability (Section 38 BSIG)
One of the most impactful provisions of the German implementation. Management bodies are personally liable for cybersecurity compliance.

Three Core Duties

Approval (Billigung)

Management must formally approve cybersecurity risk management measures per Section 30 BSIG.

Oversight (Überwachung)

Active monitoring of implementation - not passive awareness. Management must verify that measures are actually being implemented.

Training (Schulung)

Mandatory personal participation in cybersecurity training at minimum every 3 years. This duty cannot be delegated.

Executives are personally liable to their own company when they culpably violate these duties. Delegation of operational tasks is permitted, but strategic responsibility and oversight remain with management. Management cannot claim lack of technical knowledge as defense.

Section 38 BSIG explicitly prohibits contractual liability waivers by shareholders that are disproportionate to existing uncertainty regarding rights.

BSI Registration
All entities classified as besonders wichtige or wichtige Einrichtungen must register with the BSI.

Deadline: 6 March 2026 (3 months after the BSIG entered into force).

Registration uses a two-step process: first create an account via Mein Unternehmenskonto (MUK/ELSTER), then register via the BSI portal (live since 6 January 2026).

Registration is a self-identification obligation - no notification from BSI. Companies must determine themselves whether they are in scope. The BSI can also order a company to register if it determines the company falls within scope.
