Renewal of the active network infrastructure
As part of this project, the existing active network infrastructure was modernized and aligned for the future. The goal was to introduce a high-performance, secure, and scalable network and WLAN infrastructure, including a Network Access Control (NAC) solution to improve network security and central access control.
At the start of the project, a comprehensive requirements analysis was carried out, taking into account the technical, operational, and security-related needs of the clinic sites. Based on this, a technical tender was prepared for new switches, WLAN access points, and the NAC solution.
By successfully delivering the project, a modern, standardized, and secure network infrastructure was established that meets the growing demands for availability, mobility, and IT security in clinical operations.
Tasks:
- Support of the tender process, including technical evaluation of the offers and bidder assessment
- Lead and coordinate the entire project delivery
- Align the project process with internal stakeholders, business units, and the hospital IT team
- Manage external service providers during implementation and installation of the systems
- Monitor implementation, including quality control, project acceptance, and issue management
- Coordinate communication between hospital IT and external service providers during the NAC implementation
- Carry out escalation management for technical and organizational challenges
- Ongoing budget tracking as well as monitoring of project effort and additional costs
- Prepare decision papers on project changes, additional services, and risks for management

Security Architect at Capgemini
I implemented a Zero-Trust architecture for robust, military-grade maritime container mini data centers based on VMware & Tanzu to support containerized GIS workloads for ground forces. The main focus was on securing communications, workload protection, and data access in contested electronic battle environments affected by jamming, interception, signal manipulation, and constantly changing operational conditions. I designed and architected use cases so that every element of workload, identity, and system could continue to operate independently and securely even in degraded or disrupted scenarios. In parallel, I defined the enterprise and solution security architecture with LeanIX, Bizzdesign, and HOPEX as enterprise architecture, repository, and governance platforms to maintain architecture inventory, relationships, traceability, target pictures, and security governance in complex environments. For the architectural designs, I used Sparx Enterprise Architect to describe formal architecture views, interfaces, trust boundaries, and system architecture in both IT and OT environments. IriusRisk was used for threat modeling of the solution to identify architecture-driven risks, derive security requirements, and detect countermeasures and design gaps directly from the solution models. Risk and compliance management was supported with Archer. Architecture decisions, control gaps, and operational risks were translated into controlled governance and auditable compliance measures. For documentation, collaboration, and visual design, I used Confluence to maintain Architecture Decision Records, Security Blueprints, and workflows. I used Lucidchart and draw.io to create design artifacts tailored to stakeholders. I also defined OT security concepts with support from electrical and mechanical engineers in the areas of oil, vehicle onboard systems, rail, power plants, pharma, gas turbines, and nuclear technology. I created the end-to-end OT security strategy, starting with global policy, developed into standards and procedures, and finally aligned with Bell-LaPadula, Purdue Model, SABSA, TOGAF ADM, CENELEC 50701, IEC 62443, and NIST standards. In addition, I worked with engineering team leads to identify critical KBP assets and place them under protective measures that segmented SCADA, PLC, and HMI assets. I drove collaboration between Security, IT, and OT teams to create standardized workflows and use cases for the OT security solution catalog, while integrating Defense-in-Depth and Zero-Trust principles into operational environments. A key part of my work was integrating multidisciplinary engineering, security, and operations stakeholders into a unified security blueprinting strategy and ensuring that architecture, threat modeling, governance, and documentation were technically strong and operationally practical.

About the technology
What NAC does
Network Access Control, commonly called NAC, decides which users and devices may connect to corporate networks. It checks identity, device posture, location and policy before granting access, then can limit or remove access when conditions change. NAC protects wired, wireless, VPN and increasingly cloud-connected environments.
Core capabilities
NAC specialists translate access rules into enforceable controls across switches, wireless controllers, firewalls and identity services. Their work often includes:
- 802.1X authentication with RADIUS and certificates
- Guest, contractor and device onboarding
- Role-based access and network segmentation
- Posture checks for managed and unmanaged endpoints
- Quarantine workflows for non-compliant devices
Ecosystem and tooling
Common platforms include Cisco Identity Services Engine (Cisco ISE), Aruba ClearPass and Fortinet FortiNAC. Projects also connect NAC with Microsoft Entra ID, Active Directory, PKI, endpoint management, SIEM systems and firewalls. Strong professionals understand switching, wireless LANs, DHCP, DNS, RADIUS, TACACS+ and certificate lifecycles.
When companies need help
Companies bring in freelance expertise during network migrations, zero-trust programmes, office consolidations and security reviews. Specialist support is useful when an existing NAC rollout causes authentication failures, when unmanaged devices need controlled access, or when segmentation must expand without disrupting operations. In Germany, on-site workshops may matter for factories, hospitals and other locations with physical network estates, while policy design and troubleshooting can often happen remotely.
Typical project deliverables
A NAC engagement should produce clear, testable outcomes rather than only a configured appliance. Typical deliverables include:
- Current-state assessment and access-control design
- Identity, certificate and device-classification rules
- Switch and wireless integration plans
- Pilot, migration and rollback procedures
- Monitoring dashboards, runbooks and handover documentation
What strong specialists bring
Experienced NAC professionals combine security judgement with practical network operations. They test policies against printers, phones, IoT equipment, personal devices and legacy systems instead of assuming every endpoint behaves like a managed workstation. They also document exceptions, protect user experience, and explain access decisions clearly to security, infrastructure and local site teams. The best fit depends on the environment, platform mix and need for remote or on-site collaboration.
Frequently asked questions
Everything clients usually want to know about Network Access Control, in one place.
Network Access Control verifies users and devices before allowing them onto a network. It can assign access by role, isolate unknown endpoints, and enforce requirements such as valid certificates, managed status or security software.
NAC controls admission to the network, often at the switch, wireless or VPN edge. A firewall filters traffic between network zones, while zero-trust access solutions commonly provide application-level access without exposing the wider network; many organisations use these controls together.
A strong Network Access Control specialist usually understands switching, wireless networks, RADIUS, 802.1X, PKI and identity directories. Experience with endpoint management, SIEM integration, segmentation and firewall policy is also valuable.
The right level of NAC experience depends on scope, device diversity and the state of the existing network. A focused policy review may need a specialist for a short engagement, while a multi-site rollout requires proven migration planning, testing and incident troubleshooting.
Network Access Control design, policy work and many troubleshooting tasks can be performed remotely with secure access to management systems. Site surveys, switch changes, hardware checks and factory or hospital rollouts may require on-site collaboration in Germany, so the working model should be agreed early.
Common NAC platforms include Cisco ISE, Aruba ClearPass and Fortinet FortiNAC. The best choice depends on the existing switching and wireless estate, identity sources, endpoint types, licensing model and the team’s operational skills.
Ask how the Network Access Control professional handles legacy devices, failed authentication, certificate expiry and emergency access. A high-quality specialist can show a method for discovery, pilot testing, rollback, documentation and measurable policy validation without relying on disruptive trial and error.
Before starting NAC work, clarify the platforms in scope, identity sources, network locations, endpoint inventory and change-control process. It is also important to agree on access to logs, maintenance windows, on-site requirements and who owns policy decisions after handover.
The average hourly rate of freelancers in Germany who have used Network Access Control in their recent projects is 104 €, which corresponds to a daily rate of about 835 € based on an 8-hour working day.
Of the freelancers in Germany who have used Network Access Control in their recent projects, 68% hold at least a Bachelor's degree and 40% hold at least a Master's degree.
