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

Enrique Gallardo
Last position:
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 decides who and what can connect to a corporate network. It checks device identity, user identity, posture, and policy before allowing access to wired, wireless, or VPN resources. Strong setups reduce rogue devices, unmanaged endpoints, and risky guest access.
Typical work
- 802.1X design and rollout
- RADIUS, certificates, and guest access flows
- Posture checks for managed and BYOD devices
- Role-based policies for switches, Wi-Fi, and VPN
- Segmentation for contractors and sensitive systems
Tooling and ecosystem
Common projects use Cisco ISE, Aruba ClearPass, or FortiNAC, often alongside Active Directory, PKI, SIEM, and MDM tools. The work also touches switches, access points, VPN concentrators, and certificate services. Good professionals know how policy moves across this stack without blocking valid users.
When companies bring in help
Companies usually need freelance expertise during migrations, audits, network refreshes, or when access rules have grown messy. In Germany, this often comes up in industrial, logistics, healthcare, and regulated office environments where both security and stable operations matter. Remote work is common for policy design, while on-site time helps with switch, Wi-Fi, and certificate testing.
What strong specialists do
A strong specialist can read network design, spot identity gaps, and keep access decisions understandable for operations teams. They document policy clearly, test edge cases, and work cleanly with security, infrastructure, and workplace teams. They also know when NAC should enforce policy and when another control is the better fit.
Deliverables
Good engagements end with working policy, not just diagrams. Expect clear access rules, exception handling, rollback steps, and handover notes that let internal teams support the setup. For larger environments, specialists also prepare phased rollout plans so departments can move without disrupting daily work.
Frequently asked questions
Everything clients usually want to know about Network Access Control, in one place.
Network Access Control is used to decide which users, devices, and segments can join a network and under what conditions. It is common for wired access, Wi-Fi, guest networks, contractor access, and VPN entry. The goal is to keep unmanaged or risky endpoints out while letting approved devices connect cleanly.
NAC works closest to the point of connection, while firewalls control traffic after access has already been granted. It is often part of a broader zero trust design, but it does not replace identity, endpoint security, or network segmentation. Companies use it when they need enforcement at the switch, access point, or VPN gate.
A strong Network Access Control specialist usually knows 802.1X, RADIUS, certificates, and directory integration. Experience with Cisco ISE, Aruba ClearPass, or FortiNAC is valuable, along with switch and Wi-Fi policy work. It also helps if the person understands PKI, MDM, and incident-safe rollout planning.
Yes, because Network Access Control changes can affect login, onboarding, and device access across the business. Small policy updates can be handled by a capable specialist, but migrations and first-time deployments need someone who has already untangled certificate, identity, and exception flows. The more mixed your device landscape, the more valuable that experience becomes.
Network Access Control work is often remote for policy design, documentation, and troubleshooting logs. On-site access is useful when testing switch templates, Wi-Fi onboarding, or certificate enrollment in a live environment. Many companies in Germany use a hybrid setup: remote planning, then targeted on-site validation.
Cisco ISE is one of the best-known platforms used to deliver Network Access Control, but it is not the concept itself. NAC is the policy and control model; ISE is one implementation of it. Other common products include Aruba ClearPass and FortiNAC.
You usually need Network Access Control help when guest access is inconsistent, BYOD is unmanaged, or unknown devices keep appearing on the network. Another sign is when manual exceptions have spread across teams and no one can explain the current policy. If certificate or 802.1X issues keep breaking access, specialist support is a good idea.
Look for clear design thinking, not just product familiarity. A strong Network Access Control professional can explain policy choices, show how they tested edge cases, and describe rollback steps if access breaks. Good deliverables include clean documentation, phased rollout planning, and realistic handling of exceptions.
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 833 € based on an 8-hour working day.
