6 QUESTIONS, BRIEFLY ANSWERED

Frequently asked questions about KRITIS Implementation

What is KRITIS and which companies are affected?

KRITIS (Kritische Infrastrukturen) refers to Germany critical infrastructure regulation covering 10 sectors including energy, water, healthcare, finance, and transport. The 2026 KRITIS Umbrella Act expanded the scope from 2,000 to over 30,000 affected organizations, any operator whose failure would endanger public supply.

What are the key requirements for KRITIS operators?

KRITIS operators must implement appropriate organizational and technical measures under Section 8a BSIG, establish an ISMS (ISO 27001 or sector-specific B3S), register with the BSI, report security incidents within 24 hours, and provide compliance evidence every two years through audits.

How long does a KRITIS implementation project take?

A typical KRITIS implementation spans 6 to 18 months depending on organizational complexity. The five phases include gap assessment, ISMS establishment, technical and organizational measure deployment, BSI audit preparation, and continuous improvement. Operators must register within 3 months of classification.

What changes with the KRITIS Umbrella Act (Dachgesetz)?

The KRITIS Umbrella Act shifts from pure cybersecurity to an all-hazards approach including physical resilience. Operators must conduct risk analyses every four years, develop resilience plans, and register by July 2026. It also introduces municipal waste disposal and public administration as newly regulated sectors.

What is the difference between KRITIS and NIS2?

KRITIS is Germany national critical infrastructure regulation under the BSI Act, while NIS2 is the EU-wide network and information security directive. KRITIS applies as lex specialis, KRITIS operators face stricter requirements than the NIS2 Implementation Act, including higher audit obligations and shorter incident reporting windows.

How does ADVISORI support KRITIS implementation?

ADVISORI guides critical infrastructure operators from initial protection needs analysis through ISMS implementation (ISO 27001 or B3S) to successful BSI compliance audits. Our approach includes gap analysis, measure planning, staff training, and Section 8a audit preparation, practical and sector-specific.
