Our Competencies
Choose the area that fits your requirements
BSI certification requires thorough preparation. We guide you through the entire audit process — from documentation through on-site audit to follow-up.
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.
The BSI Grundschutz methodology (BSI 200-2) defines three protection levels. We implement the right approach for your organization.
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.
We help you connect BSI methodology with the applicable Compendium building blocks: define your information domain, assess protection needs and document implementation gaps, owners and evidence.
