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.
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.
Frequently Asked Questions about BSI Grundschutz Certification
How much does BSI IT-Grundschutz certification cost?
The cost of BSI IT-Grundschutz certification depends on the size of the information domain, the number of building blocks and the existing maturity level. For mid-sized organizations, consulting fees typically range from EUR 30,
000 to EUR 80,000, plus the fees for the BSI certification audit conducted by an accredited auditor. ADVISORI provides a binding quote with a transparent cost breakdown after a free initial assessment.
How long does BSI IT-Grundschutz certification take?
The timeline depends on the scope and current state of information security. Typically the full process from protection needs assessment to successful audit takes between
9 and
18 months. Organizations with an existing ISMS based on ISO 27001 can transition to BSI IT-Grundschutz significantly faster.
What is the difference between ISO 27001 and ISO 27001 based on IT-Grundschutz?
With standard ISO 27001 certification the organization selects security controls based on its own risk analysis. With ISO 27001 based on IT-Grundschutz the BSI compendium prescribes specific building blocks and requirements that must be implemented. The BSI approach is more prescriptive with less flexibility in control selection, but delivers a higher and more verifiable level of protection.
What steps does the BSI Grundschutz certification process involve?
The certification process follows these phases: 1. Definition of the information domain and protection needs assessment. 2. Modelling according to BSI Standard 200–2 and mapping of compendium building blocks. 3. IT-Grundschutz check: comparison of implemented controls against requirements. 4. Supplementary risk analysis for elevated protection needs. 5. Implementation of missing controls. 6. Preparation and execution of the certification audit by a BSI-certified auditor.
Who is BSI IT-Grundschutz certification mandatory for?
German federal agencies are required to implement IT-Grundschutz under the UP Bund framework. Critical infrastructure operators must demonstrate adequate security measures under section 8a BSIG, and BSI Grundschutz certification is a recognized proof of compliance. Organizations classified as important or essential entities under NIS 2 also benefit from the certification as evidence of regulatory compliance.
How does ADVISORI prepare organizations for the BSI certification audit?
ADVISORI starts with a gap analysis against the BSI Grundschutz Compendium to identify open controls. We then support the implementation, create the required documentation (security concept, risk analysis, action plan) and conduct an internal pre-audit. During the pre-audit we simulate the audit situation, prepare key staff for interviews and ensure all evidence is documented in an audit-ready format.
How is BSI Grundschutz certification maintained after the audit?
The BSI certificate is valid for three years and requires annual surveillance audits. Between audits, changes to the information domain must be documented and new building blocks from updated compendium editions must be incorporated. ADVISORI offers a continuous support program that prepares for annual surveillance audits and ensures the ISMS stays current.
