NIS2, DORA, and the BSI Situation Report 2024 make it unambiguous: perimeter security has failed. 70% of all successful cyberattacks exploit lateral movement within the network — exactly what Zero Trust prevents. We implement Zero Trust architectures in accordance with NIST SP 800-207, continuously verifying every identity, every device, and every data stream. As a BeyondTrust partner, we combine strategic consulting with leading PAM technology — for a security architecture that meets regulatory requirements and measurably reduces attack surfaces.

We offer you tailored solutions for your digital transformation
We analyze your current security architecture against the CISA Zero Trust Maturity Model and NIST SP 800-207. The result: a detailed maturity model across all seven pillars, a prioritized roadmap with quick wins (typically 3–6 months for initial results), and a business case with ROI calculation. Existing investments, cloud strategy, and regulatory requirements (NIS2, DORA, ISO 27001) are all taken into account.
Identity is the new perimeter boundary. As a BeyondTrust partner, we implement Privileged Access Management, just-in-time access, and least-privilege concepts at enterprise level. The solution encompasses: Privileged Remote Access, Password Safe, Endpoint Privilege Management, and Identity Security Insights. 80% of all breaches involve compromised credentials — PAM is the single most effective lever.
We eliminate flat networks through granular microsegmentation. Each application and workload receives its own security zones with dynamic policies. Lateral movement — the core of modern attacks (SolarWinds, NotPetya) — becomes structurally impossible. Implementation proceeds in phases: visibility phase, policy design, enforcement, and continuous optimization.
Traditional VPNs grant overly broad network access and represent a primary attack vector. ZTNA replaces VPN with application-specific tunnels that verify identity and context at every access request. We design and implement ZTNA architectures for remote work, cloud workloads, and third-party access — vendor-agnostic and integrated into your existing security infrastructure.
Zero Trust does not end at access control — continuous monitoring is the nervous system of the architecture. We implement SIEM/SOAR integration, User and Entity Behavior Analytics (UEBA), and automated policy adjustment based on real-time risk assessments. Anomalous access patterns are detected and contained within seconds.
Choose the area that fits your requirements
82% of all cyberattacks exploit known vulnerabilities that a structured framework would have prevented (Verizon DBIR 2024). But which framework fits your industry, company size and regulatory environment? ADVISORI develops your individual cyber security strategy — from gap analysis through framework selection to a prioritised security roadmap.
NIS2 enshrines personal liability of senior management for cybersecurity — with fines of up to EUR 10 million or 2% of global turnover. ADVISORI develops governance structures that clearly define board-level responsibilities, present risks transparently in executive dashboards, and position your organization for demonstrable compliance.
German companies suffered EUR 206 billion in total losses from cyberattacks in 2023 (Bitkom). Only 15% invest proactively in security strategy (PwC). ADVISORI develops your cybersecurity strategy based on a structured maturity assessment — with a clear 3-year roadmap, prioritized measures, and a robust business case for executive leadership and the board.
82% of cybersecurity incidents trace back to organizational weaknesses — missing roles, unclear responsibilities, and gaps in escalation paths. Information Security Governance closes this gap by translating strategic protection objectives into binding structures. As an ISO 27001-certified consulting firm with over 150 specialist consultants, ADVISORI designs tailored governance models based on the Three Lines of Defense principle: operational controls (1st Line), risk management and compliance (2nd Line), and independent assurance (3rd Line). We build your CISO office, define your hierarchical policy framework, and conduct governance maturity assessments that quantify your current state and deliver a prioritized roadmap — audit-proof for BaFin, BSI, and ISO audits.
An ISMS is not a paper exercise — it is the operational backbone of your information security. Whether building from scratch to ISO 27001:2022, transitioning from the 2013 version, or optimizing an existing system: ADVISORI brings experience from over 50 ISMS projects. Our proven roadmap guides you in 6–12 months from initial gap analysis through structured ISMS build-up to successful certification — audit-proof and practical.
An effective information security strategy is more than a document — it is the strategic compass for all security decisions in your organization. According to the BSI Situation Report 2025, 68% of companies rate the threat level as high or very high, yet only 23% have a comprehensive security strategy. ADVISORI supports you as an experienced strategic advisor in developing a tailored information security strategy: from maturity assessment through security program roadmap to investment planning. Our CISO strategic advisory connects regulatory requirements (NIS2, DORA, ISO 27001) with your business objectives — making security a business enabler. With over 150 specialist consultants and experience from financial institutions, critical infrastructure, and upper mid-market companies, we deliver no standard concepts, but robust strategies with measurable value.
Security metrics that trigger decisions — not just fill dashboards. We develop strategic KPI frameworks for board reporting, security ROI measurement, and maturity scoring based on ISO 27004, NIST CSF, and CIS Benchmarks.
A policy framework is more than a document collection — it is the strategic foundation of your information security. From the overarching information security policy through topic-specific guidelines to operational work instructions: every level must be aligned, meet regulatory requirements, and function in day-to-day operations. ISO 27001 Annex A Control A.5.1 and NIS2 Article 21 require a hierarchical policy set — but the real challenge lies in strategic design: Which policy architecture fits your organization? How do you ensure policies are lived, not shelved? ADVISORI develops policy frameworks with strategic foresight. We combine ISO 27001, BSI IT-Grundschutz (ORP.1), NIST SP 800-53, and industry-specific requirements into a coherent governance framework. Our approach: policy architecture design, structured lifecycle management, and policy compliance automation — for policies that are audit-proof, clearly written, and sustainably maintainable.
An effective IT security strategy starts not with technology, but with prioritization. We analyze your risk landscape, evaluate the cost and benefit of each measure, and develop a security roadmap that deploys your budget where it delivers the greatest protection. Drawing on experience from financial regulatory audits, critical infrastructure environments, and over 150 consultants.
Traditional security trusts everything within the network perimeter. Zero Trust eliminates this implicit trust entirely: every access request is verified in real time based on identity, device context, and risk assessment — regardless of whether the user is working in the office, from home, or in the cloud. The principle 'Never Trust, Always Verify' has been standardized through NIST SP 800–207 and is today the de facto standard for modern security architectures.
A full Zero Trust transformation is a multi-year program (typically 2–4 years). However, first quick wins can be realized within 3–6 months — e.g., MFA rollout, Privileged Access Management with BeyondTrust, or ZTNA for critical applications. We work with a phased approach that delivers immediate security gains while simultaneously building the long-term architecture.
Costs vary significantly depending on the starting point, company size, and target vision. An initial assessment workshop with roadmap typically falls in the five-figure range. The total investment pays off through reduced breach costs (average: USD 4.45 million according to the IBM Cost of a Data Breach Report 2023), lower compliance overhead, and consolidated security tools. We prepare a detailed business case with ROI calculation.
Especially for cloud environments. In multi-cloud and hybrid scenarios, there is no longer a traditional perimeter. Zero Trust is the native security model for the cloud. NIST SP 800‑207A explicitly addresses Zero Trust for cloud-based applications. All major cloud providers (Azure, AWS, GCP) offer Zero Trust services that must be integrated into an overall architecture.
NIS 2 does not mention Zero Trust by name, but Article
21 requires measures that effectively amount to Zero Trust: access control policies, least privilege, multi-factor authentication, network segmentation, and continuous monitoring. DORA also requires a solid identity and access management framework under Article 9. Organizations that implement Zero Trust structurally fulfill these regulatory requirements.
Zero Trust is not a rip-and-replace approach. Legacy systems are integrated incrementally: via upstream proxy architectures, microsegmentation, and identity-aware proxies. Critical legacy systems that do not support modern authentication are secured and isolated through Privileged Access Management (BeyondTrust Privileged Remote Access). Protection increases immediately, without needing to rebuild the systems themselves.
Forrester estimates the 3-year ROI of Zero Trust at 92% for a typical enterprise. The drivers: 50% lower probability of a data breach, 50% reduction in compliance audit effort, consolidation of security tools (average 30% cost savings), and drastically reduced Mean Time to Contain (MTTC) for security incidents. Added to this is the strategic value: organizations with Zero Trust can execute cloud migration and remote work significantly faster and more securely.
