IT Security Act and KRITIS in the field of information technology & telecommunications

Optimal compliance, maximum security, and targeted measures for your company

Why IT security laws and KRITIS are becoming increasingly relevant

Rapid digitalization opens up countless opportunities—but also brings new risks. In the field of information technology and telecommunications (ICT) in particular, failures or cyberattacks can not only cause high costs, but also lead to far-reaching supply bottlenecks and impairments to public safety. For this reason, the IT Security Act (including IT Security Act 2.0) and the KRITIS (critical infrastructure) requirements impose particularly strict requirements.

Legal requirements & standards in detail

To ensure maximum IT security, the legislator has specified the following key points:

  1. Mandatory security level at “state of the art” Operators of critical infrastructures must continuously update and secure their systems in order to respond to current threats.
  2. Implementation of an ISMS (information security management system) An ISMS in accordance with ISO/IEC 27001 or BSI basic protection forms the structured foundation for the systematic planning, implementation, and control of organizational and technical measures.
  3. Risk management & obligation to provide evidence Companies must regularly identify and assess risks and derive appropriate measures. Proof must be provided to the Federal Network Agency (BNetzA) and the Federal Office for Information Security (BSI).
  4. Data protection-compliant implementation in accordance with DSGVO In addition to IT security, the legally compliant processing of personal data must be guaranteed at all times.
  5. Further industry-specific catalogs
    • Security requirements in accordance with Section 109 of the German Telecommunications Act (TKG)
    • IT security catalog for networks and energy systems
    • B3S data center, server farm, and content delivery network

 

Conclusion: Only by fully complying with and continuously documenting all requirements can costly fines and damage to reputation be avoided.

Greater security, less liability risk

A professional IT security concept offers the following measurable advantages:

  • Legal certainty & compliance minimize legal risks and fines by fully complying with all requirements of the IT Security Act and KRITIS regulations.
  • Protection against cyber attacks early detection of vulnerabilities and targeted measures significantly reduce the risk of successful attacks on your systems.
  • Competitive advantage & image boost customers, investors, and partners trust companies with certified ISMS—this creates transparency and strengthens your market position.
  • Efficient resource planning standardized processes in risk management and data protection create clear responsibilities and reduce the workload for your employees.
