LAN infrastructure: The wired foundation
We create a solid foundation. Our experts plan and implement your wired network infrastructure to the highest standards. This includes professional, structured cabling as well as the configuration of high-performance switches and routers. We ensure logical network segmentation (VLANs) to increase security and performance and intelligently control data traffic.

WLAN solutions: comprehensive, high-performance and secure
We free you from the cables. Based on professional WiFi illumination, we plan and implement a stable and secure wireless network that seamlessly covers your entire business premises in Berlin. We rely on modern, centrally managed WLAN systems that guarantee high performance even with many simultaneous users and enable a secure separation of internal and guest WLAN.

VPN & location networking: Secure connections, no matter where
We securely connect your worlds. We design and implement robust VPN (Virtual Private Network) solutions that give your employees secure and encrypted access to the company network when working from home or while traveling. For companies with multiple locations, we implement secure and high-performance site networking (site-to-site VPN or SD-WAN) so that all employees can work together seamlessly.
More than just an agency. Your external task force.
We don't just deliver code, we deliver working, maintainable and business-oriented solutions.
Tailor-made network concepts
We develop individual solutions that are tailored precisely to the size, industry and specific requirements of your Berlin company. You do not receive a standard solution, but rather a tailor-made network.
Manufacturer-independent product selection
We advise you objectively and rely on proven network components from leading manufacturers (e.g. Cisco, Ubiquiti, Fortinet) that optimally fit your needs and budget.
Focus on reliability & performance
We plan your network infrastructure so that it meets the highest standards of availability and speed. Redundant components and intelligent configurations minimize the risk of failures.
Your path to digital sovereignty
Building on this, we enable you to take the next step towards complete control, agility and the decisive advantage in your market.

Technical questions, clear answers
Structured wiring is like the clean, well-labeled fuse box in a house, as opposed to a messy mess of wires. Every connection in the office leads to a central, tidy patch panel in the server room. The advantages are immense: 1. Reliability: Significantly lower susceptibility to faults than with unprofessionally laid cables. 2. Flexibility: New connections or employee moves can be implemented quickly and easily. 3. Troubleshooting: Problems can be isolated and resolved quickly and systematically. It is a one-time investment in a stable and maintainable foundation.
A VLAN (Virtual Local Area Network) is a technique for logically dividing a physical network into multiple, separate subnets. Think of it as creating separate lanes for different types of traffic on a single, wide street, separated by guardrails. This is extremely important for security: For example, you can set up a VLAN for your internal employees, a completely separate one for your guests on the WLAN and another for sensitive devices such as servers. This means that a compromised device on the guest WiFi can never access your internal company data.
For private use yes, for a productive corporate environment definitely no. Professional WLAN solutions that we implement in Berlin consist of several, centrally managed ones Access Points. This offers crucial advantages: 1. Comprehensive coverage: Multiple access points ensure a strong signal in every corner. 2. Seamless Roaming: Employees can move around the building without the connection being lost. 3. High performance: The load of many users is distributed across multiple devices. 4. Advanced Security: Professional systems offer secure authentication methods and the separation of networks (VLANs).
