Never Trust, Always Verify
Zero Trust Framework
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.

Zero Trust Strategy & Assessment
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 & Privileged Access Management (with BeyondTrust)
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.
Microsegmentation & Software-Defined Perimeter
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.
Zero Trust Network Access (ZTNA)
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.
Continuous Monitoring & Security Analytics
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.

Frequently Asked Questions about Zero Trust Framework
What exactly is Zero Trust and how does it differ from traditional IT security?
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.
How long does it take to implement a Zero Trust framework?
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.
What does a Zero Trust implementation cost?
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.
Is Zero Trust relevant for cloud environments as well?
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.
Does NIS2 explicitly require Zero Trust?
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.
How does Zero Trust work with existing legacy systems?
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.
What concrete ROI does Zero Trust deliver?
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.
