01
Understand the need
We establish locations, users, important applications and recurring issues. We review devices, links, cabling, Wi-Fi, access rules and available configurations.
IT infrastructure
Computer network support
Unreliable Wi-Fi, branch connection problems or missing documentation? We help establish whether your network needs targeted improvements, a redesign or ongoing support. Diagnosis leads to a plan for further work. Design and deployment have a separate scope, cost and responsibilities from day-to-day administration.

Companies and institutions that need stable IT.
From a problem to the right service
Your network connects employees, servers, applications, cloud services and branches. We identify the connections and devices that matter to your business and where problems occur. In an office, this might mean Teams calls and guest access; in a warehouse, scanners moving between Wi-Fi access points; in production, separating industrial devices from the rest of the network. Not every fault calls for new equipment. We first review the network, documentation and support arrangements, then propose stabilisation, a change project or an administration handover.
Choose the network work you need
These services address different tasks. We combine them where needed, without assuming that one project includes every subsequent change or support activity.
Network deployment
A new site or LAN and Wi-Fi redesign: cabling, devices, network separation, testing and handover documentation.Firewall and segmentation
A firewall and connection rules for employees, servers, guests and external services. Rule reviews and access control.VPN and branches
Encrypted links between sites and access for employees outside the office. Permissions, additional sign-in verification and session logging.Network administration
Routine changes, updates, configuration backups, monitoring and tickets. Covered devices, support hours and reporting are agreed separately.ISO 27001 · TÜV NORD Polska
TÜV NORD Polska has certified Virtline’s information security management system to PN-EN ISO/IEC 27001:2023-08. The published certificate states its scope and validity.

We do not start with a shopping list. Each decision follows from network condition, user needs and the agreed responsibilities.
02
Choose the scope
We separate urgent fixes, redesign and recurring tasks. We agree the option, cost, approvers, migration plan, maintenance windows and checks; scheduling takes deliveries and site access into account.
03
Carry out and check the work
We make agreed changes with a configuration backup and a plan to restore the previous settings. We check connections and important applications, then document results and outstanding risks for acceptance.
04
Handover or ongoing support
We provide documentation and priorities for further work. If we take on network administration, we separately agree monitoring, tickets, updates, reports, service hours and response arrangements.
Practical scope
What the agreed work delivers
Documentation depends on whether you commission a review, deployment or ongoing support. The scope and acceptance arrangements identify specific deliverables and responsible people.
Connections, devices and ports, addressing and separate network areas (VLANs). We describe important services, firewall rules, Wi-Fi and VPN arrangements, and information gaps. We include traffic routes, standby devices and links; in data centres, this also covers switch interconnections, a separate storage network and the impact of a single component failure.
Risks, priorities and options for change with agreed dates. We compare equipment, licences and the full cost of in-house and outsourced support. The plan covers updates, vendor support, spare devices and future replacement.
A report from coverage, load, throughput and latency measurements and service access tests. During deployment, we select Wi-Fi access points, channels and power settings, then check movement between access points, traffic separation, priorities for important applications and agreed failure scenarios.
Configuration backups and versions, instructions and a recovery plan for device failure. We record change approval and rollback arrangements, reviews, monitoring and ticket escalation; credentials are handed over through a secure channel.
Network access and security
We separate network traffic from guests, personal devices and industrial devices. User and device access control (NAC/802.1X) can use certificates and allocation to the appropriate network area; exceptions are agreed. We restrict and revoke unnecessary administrator permissions, apply additional sign-in verification (MFA), and review accounts and unused rules. We recommend configuration changes to improve device security. Firewall and VPN logs can support event analysis by a separately agreed security service (SOC/SIEM). Network monitoring alone does not automatically include that analysis or the work of a security team.
Questions about network support
Can you help with networks in older buildings?
+
Yes. We start with an inventory and measurements of copper and fibre cabling and Wi-Fi. We check labelling, racks, power supplied through network cables (PoE) and backup power. We then plan cable route improvements, structured cabling or Wi-Fi changes. Building work and as-built documentation are agreed before implementation.
Do we have to replace every device?
+
We do not assume a complete replacement. We assess requirements, equipment condition, licences, support and running costs. We work with Cisco, Meraki, Aruba, Fortinet, MikroTik, Ubiquiti, pfSense and OPNsense, among others. For multiple sites, we compare SD-WAN link management with carrier services by total cost and terms, without guaranteeing a fixed saving percentage. Models and dates require a review of your environment and availability.
Can you take over from another provider?
+
Yes, after reviewing configurations, access, documentation and risks. Deployment does not automatically include ongoing administration. Monitoring can operate around the clock, but team on-call cover, support hours, response times and repair scope require separate agreement.
Can network work help us prepare for an audit?
+
Documentation, network separation, access control, logs, configuration backups and change history can support a NIS2, DORA or ISO 27001 audit. We agree responsibilities and how incident information is passed on. Network work or Virtline’s certificate alone does not establish organisation-wide compliance.
