Our Competencies
Choose the area that fits your requirements
The BSI IT-Grundschutz Compendium comprises 113 building blocks across 10 topic areas. Grundschutz++ brings digital modernization in 2026.
ISO 27001 certification based on IT-Grundschutz is the highest evidence of information security under BSI standards.
Banks and financial services providers face stringent information security requirements. BaFin mandates through BAIT and MaRisk the implementation of recognized standards such as BSI IT-Grundschutz. We guide financial institutions through structured implementation based on BSI 200-2 — from structural analysis and protection requirements to measure implementation. Our consultants understand the specific demands of financial supervision and combine IT-Grundschutz with BAIT compliance, DORA readiness, and existing ISMS structures.
Successful BSI IT-Grundschutz implementation requires more than technical execution — it needs strategic implementation frameworks that connect IT security requirements with operational excellence, technology innovation, and sustainable business strategy. Professional BSI Grundschutz implementation combines proven implementation methods with effective RegTech solutions for comprehensive IT security systems. We develop end-to-end BSI IT-Grundschutz implementation solutions that not only ensure regulatory compliance, but also increase operational IT security efficiency, enable innovation, and establish sustainable competitive advantages for German companies.
Risk analysis per BSI 200-3 is mandatory for elevated protection needs. We identify additional threats beyond standard building blocks and develop effective treatment strategies.
Frequently Asked Questions about BSI Grundschutz Methodology
What is the BSI IT-Grundschutz methodology per Standard 200-2?
The BSI IT-Grundschutz methodology is the operational guideline from Germany's Federal Office for Information Security (BSI) for implementing an Information Security Management System (ISMS). BSI Standard 200–2 describes three approaches: basic protection as a quick entry point, core protection for especially critical business processes, and standard protection as the comprehensive approach with ISO 27001 certification option based on IT-Grundschutz.
What is the difference between basic, standard, and core protection?
Basic protection provides a quick entry with fundamental security measures and suits organizations without an existing ISMS. Core protection focuses on especially critical business processes and assets (crown jewels) and protects them as a priority. Standard protection is the complete approach with structural analysis, protection requirements assessment, modeling of all modules, and enables ISO 27001 certification based on IT-Grundschutz.
What steps does the standard protection approach per BSI 200-2 include?
Standard protection follows a defined process model: 1) Defining the scope, 2) Structural analysis of the information domain, 3) Determining protection requirements for all identified target objects, 4) Modeling with appropriate modules from the IT-Grundschutz Compendium, 5) IT-Grundschutz check (target-actual comparison), 6) Supplementary risk analysis for elevated protection requirements, and 7) Consolidation and implementation of measures.
What is the IT-Grundschutz Compendium and what role does it play?
The IT-Grundschutz Compendium is the operational foundation of the methodology, containing over
100 modules across ten layers (e.g., ISMS, ORP, CON, OPS, DER, APP, SYS, IND, NET, INF). Each module describes specific requirements and implementation guidance for certain aspects of information security. During modeling, appropriate modules are mapped to the identified target objects of the information domain.
Which organizations are required to implement BSI IT-Grundschutz?
German federal agencies are obligated to implement IT-Grundschutz under the UP Bund framework. Critical infrastructure operators must demonstrate adequate security measures under Section 8a BSIG, with IT-Grundschutz recognized as valid proof. Through NIS 2 and the IT Security Act 2.0, the circle of affected organizations expands. State agencies and municipalities also increasingly follow IT-Grundschutz.
How does ADVISORI support BSI IT-Grundschutz methodology implementation?
ADVISORI guides organizations through all phases of BSI IT-Grundschutz implementation: from selecting the appropriate approach through structural analysis and protection requirements assessment to modeling, the IT-Grundschutz check, and implementing all measures. With experience from over
520 information security projects, we shorten implementation time and prepare organizations for ISO 27001 certification based on IT-Grundschutz when needed.
How long does IT-Grundschutz implementation take and what does it cost?
Duration and costs depend on the chosen approach and organization size. Basic protection for medium-sized companies can be implemented in 3–6 months. Standard protection with a certification goal typically takes 12–18 months. Consulting costs range from EUR 20,
000 to 80,
000 depending on scope. ADVISORI provides an individual project plan with transparent effort estimates after an initial analysis.
