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

Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.

About the technology
What IPsec does
IPsec, short for Internet Protocol Security, protects IP traffic through authentication, encryption and integrity checks. It operates at the network layer, so applications usually need no changes. Companies use it to connect offices, data centres, remote users and cloud environments over untrusted networks.
Core protocols
IPsec commonly uses Internet Key Exchange to negotiate security associations and encryption keys. IKEv2 is widely used for stable tunnel setup, while ESP protects the data itself; AH is less common because it does not provide encryption. Strong configurations address authentication, rekeying, routing and tunnel availability together.
Networks and tooling
Specialists work across physical and virtual firewalls, routers, Linux gateways and cloud networking services. Relevant tooling includes vendor policy interfaces, libreswan, strongSwan, packet captures and monitoring systems. They also connect IPsec decisions with:
- Public key infrastructure and certificate lifecycles
- Identity, DNS, routing and access control
- High availability and failover design
- Cloud, container and hybrid network boundaries
When companies need help
Freelance expertise is useful when a tunnel must connect incompatible environments, replace legacy VPN settings or support a demanding migration. Companies also bring in specialists when intermittent drops, negotiation failures or unexpected traffic paths are slowing operations. In Germany, remote work is often practical, while firewall changes and site surveys may require coordinated on-site access.
Delivery and troubleshooting
A reliable engagement starts with a clear traffic model, endpoint inventory and security policy. Professionals map subnets, choose authentication methods, document proposals and test both normal and failover paths. They inspect logs and packet captures to separate IKE negotiation problems from routing, NAT, MTU or firewall issues.
What strong specialists show
Look for professionals who can explain security trade-offs without hiding behind vendor terminology. They should distinguish policy-based from route-based VPNs, understand NAT traversal and verify encryption rather than relying on a tunnel status alone. Good deliverables include tested configurations, diagrams, rollback steps, monitoring guidance and concise handover documentation.
Frequently asked questions
Need clarity? These are the questions we hear most often about IPsec.
IPsec is used to secure IP traffic between networks, hosts or remote access clients. It is common for site-to-site VPNs, hybrid cloud links, branch connectivity and protected administration paths.
IPsec works at the network layer and is deeply supported by enterprise firewalls and routers. SSL VPNs can be convenient for application-oriented remote access, while WireGuard is known for a smaller design and simpler configuration; the right choice depends on endpoints, policy, interoperability and operational needs.
A strong IPsec professional usually understands routing, NAT, firewalls, DNS and identity systems. Experience with certificates, PKI, Linux networking, cloud connectivity, monitoring and packet analysis is especially valuable when tunnels cross several environments.
The right level depends on the scope. A straightforward tunnel may need focused configuration skills, while a multi-site or hybrid design calls for someone who can model routing, authentication, failover, migration risks and operational ownership.
IPsec work is often suitable for remote collaboration when the professional has secure administrative access, accurate network documentation and a test path. On-site involvement can still help with physical firewalls, network handoffs or troubleshooting that depends on local equipment in Germany.
Common IPsec failures come from mismatched proposals, credentials, certificates, traffic selectors or lifetimes. NAT traversal, blocked UDP traffic, incorrect routes, overlapping subnets and MTU problems can also create tunnels that appear established but do not carry useful traffic.
Ask the IPsec professional to explain the threat model, configuration choices and recovery plan in plain language. Quality work includes least-privilege policies, tested failover, useful monitoring, documented dependencies and evidence that traffic is encrypted and routed as intended.
An IPsec handover should include topology diagrams, endpoint and subnet details, authentication ownership, configuration records and monitoring instructions. It should also describe renewal procedures, rollback steps, known limitations and a test record for normal operation and recovery.
The average hourly rate of freelancers in Germany who have used IPsec in their recent projects is 107 €, which corresponds to a daily rate of about 852 € based on an 8-hour working day.
Of the freelancers in Germany who have used IPsec in their recent projects, 76% hold at least a Bachelor's degree, 48% hold at least a Master's degree, and 3% hold a doctorate.
On average, freelancers in Germany who have used IPsec in their recent projects have 22 years of professional experience, with a single engagement typically lasting around 2.4 years.
The most common languages among freelancers in Germany who have used IPsec in their recent projects are German (100%), English (100%), and French (17%).
The most common industries among freelancers in Germany who have used IPsec in their recent projects are Information Technology (91%), Manufacturing (53%), and Automotive (49%).
