Renewal of the Active Network Infrastructure
As part of this project, the existing active network infrastructure was modernized and made fit for the future. The goal was to introduce a powerful, secure and scalable network and WLAN infrastructure, including a Network Access Control (NAC) solution to improve network security and centralized access control.
At the beginning of the project, a comprehensive requirements analysis was carried out, taking into account the technical, operational and security-related requirements of the hospital sites. On this basis, a technical tender was prepared for new switches, WLAN access points and the NAC solution.
The successful implementation of the project established a modern, standardized and secure network infrastructure that meets the growing requirements for availability, mobility and IT security in hospital operations.
Activities:
- Supporting the tender process, including technical evaluation of offers and bidder evaluation
- Leading and managing the entire project implementation
- Coordinating the project process with internal stakeholders, business units and hospital IT
- Managing external service providers during the implementation and installation of the systems
- Monitoring the implementation, including quality control, project acceptance and defect management
- Coordinating and managing communication between hospital IT and external service providers as part of the NAC implementation
- Managing escalations in the event of technical and organizational challenges
- Ongoing budget monitoring and control of project expenses and additional costs
- Preparing decision papers for management on project changes, additional services and risks

About the role
Secure the network
Network security engineers protect the paths your data takes. They design and harden firewalls, segment networks, manage secure remote access, and reduce exposure across offices, data centers, cloud setups, and hybrid environments. Their work keeps business traffic moving while blocking misuse, lateral movement, and avoidable risk.
Typical deliverables
- Firewall rule design, review, and cleanup
- Network segmentation and zone architecture
- VPN, remote access, and site-to-site connectivity
- IDS/IPS tuning and alert reduction
- Secure cloud networking and perimeter controls
- Hardening for routers, switches, and network services
Core skills
A strong network security engineer knows how to translate policy into working controls. Expect hands-on experience with firewalls, NAC, proxy services, DNS security, routing, switching, load balancers, and common platforms from vendors such as Palo Alto Networks, Fortinet, Check Point, Cisco, and Juniper.
They should also understand threat modeling, logging, packet analysis, and incident support. In Germany, many clients want someone who can work with internal IT, security teams, auditors, and infrastructure providers without slowing delivery.
When companies hire
Companies bring in a freelance network security engineer when a project needs focused expertise, not a long hiring process. Common cases include firewall migrations, cloud expansion, segmentation after a security review, merger integration, secure access for remote teams, or support during an audit and remediation phase.
This role is a good fit when you need a network security engineer, network security specialist, or network security consultant who can step in quickly, assess the current setup, and deliver practical changes without redesigning the whole stack.
What strong freelancers do
A good professional does more than change rules. They document decisions, test changes safely, coordinate with operations, and leave the environment cleaner than they found it.
- Validate changes before production rollout
- Explain risks in plain language
- Work well with infrastructure and cloud teams
- Keep logs, diagrams, and handover notes current
- Balance protection with network availability
- Support both project work and incident response
Tools and environments
Network security engineers often work across on-premises, cloud, and hybrid environments. Common tools include SIEM and log platforms, packet analyzers, vulnerability scanners, NAC systems, and vendor consoles for firewall and VPN management.
The best freelancers adapt to your stack instead of forcing a preferred setup. They can support migrations, temporary coverage, hardening initiatives, and steady-state operations where security and uptime both matter.
Frequently asked questions
Curious about Network Security Engineers? Here are the answers that come up again and again.
A Network Security Engineer designs and improves the controls that protect network traffic. That usually includes firewalls, segmentation, secure remote access, rule reviews, VPNs, and support during changes or incidents. Freelancers are often brought in to solve a defined problem fast and leave the setup easier to maintain.
Hire a network security engineer freelancer when the need is project-based, urgent, or tied to specialist know-how. That makes sense for firewall migrations, cloud connectivity, audit preparation, or short-term coverage. A permanent hire is better when you need long-term ownership of a broad security program.
A strong network security specialist needs hands-on knowledge of firewalls, routing, switching, VPNs, segmentation, and log analysis. They should also be comfortable with packet inspection, incident support, and coordination with infrastructure teams. Clear documentation and careful change management matter just as much as technical depth.
A Network Security Engineer focuses on protection, not just connectivity. A network engineer may build and run the network itself, while this role hardens it, limits exposure, and monitors for misuse. In many companies the work overlaps, but the security mindset changes the priorities.
A network security consultant often works with firewall consoles, VPN gateways, IDS/IPS tools, NAC systems, SIEM platforms, and packet analyzers. Common vendor environments include Palo Alto Networks, Fortinet, Check Point, Cisco, and Juniper. The exact stack depends on whether the client runs on-premises, cloud, or hybrid networks.
A Network Security Engineer can do much of the analysis, documentation, and rule work remotely. On-site access becomes useful for hardware changes, network closets, migration windows, or sensitive environments. In Germany, many clients use a mix of remote delivery and on-site time for critical changes.
Look for a network security engineer who explains trade-offs clearly and does not create unnecessary complexity. Good signs are clean change plans, sensible rollback steps, tested rules, and documentation that your team can actually use. They should improve security without interrupting business traffic.
A network security engineer freelancer should expect a mix of technical work and stakeholder coordination. Clients may want assessments, remediation, migrations, or short-term incident support, often in environments with strict change control. Success depends on understanding the current network, asking the right questions, and delivering changes safely.
The average hourly rate for Network Security Engineers in Germany is 102 €, which corresponds to a daily rate of about 819 € based on an 8-hour working day.
