NIST CSF 2.0 · ISO 27001 · BSI IT-Grundschutz
82% of all cyberattacks exploit known vulnerabilities that a structured framework would have prevented (Verizon DBIR 2024).
A cyber security strategy is more than selecting a framework — it connects business objectives, risk appetite and regulatory requirements into a viable security concept. ADVISORI guides you through four phases: In the analysis phase, we evaluate your current security posture through a comprehensive security assessment, identify vulnerabilities and benchmark your maturity against industry standards.
Our expert consultants provide comprehensive cyber security framework services tailored to your organization's specific needs. We combine deep regulatory expertise with practical implementation experience to deliver measurable results.

Implementation of the NIST Cybersecurity Framework 2.0 with all six core functions: Govern, Identify, Protect, Detect, Respond, and Recover. The new Govern function anchors cybersecurity at the board level — a decisive advantage over version 1.1. We develop your organization-specific profile, map existing controls, and systematically close gaps.
Establishing a complete ISMS in accordance with ISO 27001:2022 — from scope definition and risk analysis through to a successful certification audit. The 2022 version reduces controls from 114 to 93 across four categories (organizational, people, physical, technological) and introduces 11 new controls, including threat intelligence and cloud security.
Implementation of the BSI IT-Grundschutz compendium for German organizations and KRITIS operators. We guide you through basic, standard, and core protection approaches, develop structural analyses and modeling, and prepare you for BSI certification to ISO 27001 based on IT-Grundschutz — including NIS2 compliance.
Systematic assessment of your current state against the target framework with a quantified maturity level on a 5-point scale. The result: a prioritized action plan with quick wins (0–3 months), medium-term measures (3–12 months), and strategic initiatives — including effort and budget estimates.
Many organizations are subject to multiple regulatory requirements simultaneously: DORA, NIS2, BAIT, VAIT. We develop an integrated control framework that utilizes overlaps between NIST CSF, ISO 27001, and industry-specific requirements — saving up to 40% of implementation effort through shared controls.

6 QUESTIONS, BRIEFLY ANSWERED
The choice depends on your industry, regulatory environment, and objectives. ISO 27001 is the standard for organizations seeking an internationally recognized certification. NIST CSF 2.0 serves as a flexible, risk-based framework — particularly where no certification requirement exists. BSI IT-Grundschutz is often mandatory for KRITIS operators and public institutions in Germany. For financial firms, BAIT/VAIT and DORA are additionally relevant. ADVISORI advises across industries and recommends the framework that fits your risk profile and regulatory landscape.
Published in February 2024, NIST CSF 2.0 introduces three key changes: First, the new Govern function, which explicitly anchors cybersecurity at the leadership level and defines responsibilities, policies, and risk management strategies. Second, a broader target audience — the framework now applies to all organizations, not just critical infrastructure. Third, improved implementation guidance with concrete profiles and tier descriptions for maturity assessment.
Duration varies depending on scope and maturity level: A NIST CSF 2.0 implementation typically takes 4–8 months, ISO 27001 certification 8–18 months, and BSI IT-Grundschutz 12–24 months. We recommend a phased approach: Quick wins in the first 3 months (policies, risk register, top‑10 controls), followed by systematic build-out. This delivers visible improvements quickly while ensuring sustainable development.
The investment depends on company size, the chosen framework, and current maturity level. For a mid-sized company (500–2,000 employees), ISO 27001 certification typically involves consulting costs of EUR 80,000–250,000 plus internal effort. A NIST CSF assessment with roadmap starts at approximately EUR 30,000. Crucially, the cost of a framework implementation is a fraction of the average cost of a data breach — according to the IBM Cost of a Data Breach Report 2023, this stands at USD 4.45 million globally.
Each industry has its own regulatory requirements that influence the framework selection: Banks must comply with BAIT and, from 2025, DORA; insurers must comply with VAIT. KRITIS operators are subject to the IT Security Act 2.0 and, going forward, NIS2. Pharmaceutical and medical technology companies require GxP-compliant IT security. ADVISORI has extensive experience across all these industries and integrates sector-specific requirements directly into the chosen framework.
Yes, and this is even recommended. NIST CSF 2.0 and ISO 27001:2022 complement each other ideally: NIST provides the risk-based framework with clear functions and categories, while ISO 27001 delivers the detailed controls and certification path. Approximately 80% of NIST CSF subcategories can be directly mapped to ISO 27001 controls. ADVISORI develops an integrated control framework that covers both standards and avoids duplication of effort.
