A stable network as the basis of every IT
Design and management of corporate networks — LAN, Wi-Fi, firewall, VPN and VLAN segmentation. With monitoring, documentation and SLA response for critical outages.
The network is the artery of every corporate IT. If it is unstable, all other systems suffer — servers, telephony, e-mail, cloud applications. Network problems are also one of the most difficult incidents to diagnose if there is no documentation and monitoring.
We design, build and manage corporate networks for medium-sized companies — from simple office LANs to segmented networks with multiple VLANs, redundant transmissions and Wi-Fi coverage for production halls and office spaces.
Why it makes sense
Segmented network = less risk
VLAN for office, server, guest and IoT segment. Disruption of one segment does not compromise the others — the foundation of NIS2 and ISO 27001.
Stability for VoIP and video
QoS (Quality of Service) for voice and video communication. Phone calls and video calls do not break even when the network is under load.
Coverage without dead zones
Wi-Fi audit, correct location of access points and a controller for centralized management — stable coverage in offices, warehouses and production halls.
VPN for remote access
Secure access for home offices, branches and mobile devices — without compromising security.
What you get
- Audit of the existing network (topology, devices, configuration)
- Design of network architecture (VLAN, routing, firewall zones)
- Installation and configuration of switches, routers, firewalls
- Wi-Fi coverage — site survey, AP location, controller
- VPN for remote access (site-to-site, remote access)
- Firewall, NAT, IDS/IPS
- Monitoring network availability and performance
- Management of network devices (firmware, configuration)
- Network topology documentation
- Coordination with ISP in case of connectivity outages
Ako postupujeme
- 01
Network audit
Physical and logical topology, device inventory, configuration, security settings and identification of problem areas.
- 02
Proposal and approval
New or optimized topology, hardware recommendations, implementation plan with minimal operational impact.
- 03
Implementation
Device configuration according to best practices, testing in a test environment if possible, controlled implementation with a planned window.
- 04
Monitoring and management
Monitoring setup, final topology documentation and regular configuration and firmware management.
Why network documentation is a must
Most medium-sized companies do not have up-to-date documentation of their network. The problem appears during an incident: the technician does not know where what is, what is the configuration of the switch, where VLAN 20 ends or who has access to the server zone.
The first thing we do when we take over network management is auditing and documentation. Later, it saves time for every incident, planned change and onboarding of a new technician.
Firewall: more than just "yes/no"
A modern firewall is not just an ACL (access control list). It is:
- Stateful inspection — monitors the state of connections, not just ports and IP addresses
- Application layer filtering — understands protocols (HTTP, DNS, TLS) and can filter specific applications
- IDS/IPS — detects and blocks suspicious patterns (exploit attempts, scanning)
- URL filtering — categorization of web content to comply with company policy
- VPN concentrator — secure remote access integrated with user identity
A properly configured firewall is the basis of perimeter security. It won't stop every attack, but it will significantly narrow the attack surface.
Wi-Fi in a corporate environment
Office Wi-Fi and a network for production facilities are different requirements. Clinical signal clarity in the meeting room requires a different AP than covering a warehouse with forklifts, a camera system and MES terminals.
We do a Wi-Fi site survey — a physical or RF measurement before installation — so we know how many APs, where to place them and what channel to set them on. The result is stable Wi-Fi without overlapping, without dead zones and with traffic segregation.
FAQ
Do you work with a specific network brand or are you vendor-agnostic?
We primarily work with Cisco, Fortinet and Ubiquiti, but we can also work with other equipment. For new customers, we recommend a specific platform based on their needs and existing environment.
Can you download a network without documentation?
Yes. The first step is an audit and reverse documentation — we map what's where and create the missing documentation.
Do you also deal with ISP connectivity outages?
We coordinate communication with the ISP and monitor line availability. For critical environments, we recommend redundant connectivity from two independent ISPs.
What is VLAN and why do we need it?
VLAN (Virtual LAN) allows you to logically separate the network into segments — e.g. office, servers, guest Wi-Fi, IP cameras. Security segmentation reduces the impact of a security incident and is a requirement of ISO 27001 and NIS2.
Don't know what you have on your network? We'll find out.
A network audit will reveal unknown devices, security holes and causes of instability. He will arrange a consultation.
