01
Scope and contacts
We list locations, devices, connections, contracts and decision-makers. We agree access rights, support hours, fault reporting and the division of work between teams.
Network management
IT network administration
We maintain business wired networks, Wi-Fi and remote VPN connections. We manage devices, access rules, updates and faults, keeping documentation current after changes. We agree responsibilities, support hours and cooperation with connectivity providers.
Trusted by
Companies and institutions that need stable IT.
Who is responsible for your network?
Interruptions to Wi-Fi connections, a disconnected office or a growing list of undocumented rules call for ongoing network management. We administer switches, routers, firewalls and Wi-Fi access points. We check ports, separate network segments (VLANs), addressing, connection routes, and name and address allocation services (DNS/DHCP). We investigate congestion, loops, packet loss and coverage gaps. We review remote access, administrator accounts, certificates and rule changes that affect applications and users.
When a larger change is needed
Reviews may reveal a need to redesign part of the network or introduce a tool. These services have their own project scope and acceptance arrangements; they are not automatically included in ongoing administration.
Network implementation
A new location, additional switches, changes to network segmentation or a Wi-Fi upgrade. Design, configuration and testing before handover to operations.Firewall deployment
Selecting or replacing a firewall, transferring rules and checking service access. We agree future reviews and change handling after acceptance.VPN deployment
Setting up connections for employees and offices, with permissions and additional sign-in verification. Initial deployment and later access management have distinct scopes.IT monitoring
Introducing or improving device and connection measurements, thresholds and alerts. We separately agree who receives notifications and responds to problems.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.
View Virtline’s certificateNetwork handover process
We start with the current environment and access to devices. Changes are planned with your business and the existing provider so their impact on important services can be checked.
02
Review and save settings
We collect configurations, documentation and device software versions. We check for missing configuration backups, outdated VPN accounts, overly broad rules and unclear administrator access, recording gaps and priorities.
03
Monitoring and corrections
We organise measurements, logs and notifications. Urgent changes are made during agreed service windows, with configuration backups and a rollback plan. Connections and services are checked afterwards.
04
Ongoing operation
We hand over documentation and open issues. We agree update schedules, rule reviews and provider contacts. The monthly report supports decisions about further corrections or a separate upgrade project.
Practical scope
What ongoing support provides
Documentation and reports show network condition, completed work and open issues. They support decisions about next steps and help administrators share knowledge.
A map of devices and connections, addressing, network segments and important rules. We record responsible people, connectivity providers and contacts, updating the documentation after changes.
Device configuration and software versions, reasons for changes, approvals and test results. We agree how to reverse work before it begins; firewall and VPN rules have an owner and a review date.
Availability, load and error measurements with agreed thresholds and alert recipients. We document diagnosis, response and referrals to the provider or another team.
Incidents, availability, response times, changes and overdue updates. We present risks and priorities for Wi-Fi coverage, segmentation or resilience; proposed upgrades are submitted for a decision and costing.
Networks, systems and employee access
Network administration covers connectivity and traffic rules. Remote administration of servers, systems and applications, as well as updates, data backups, restoration and restore tests, requires a separate agreement. Account, group and role management is defined separately: who approves access, what changes when an employee joins, changes role or leaves, and when permissions are reviewed. This also covers administrator access and additional sign-in verification (MFA). Endpoint protection and handling detected threats (EDR/MDR) may be recommended as part of a broader scope. Network records can support audits, but administration alone does not establish compliance with NIS2 or organisation-wide conformity with ISO 27001.
Questions about network administration
Can you take over a network without full documentation?
+
We can start by establishing what is missing and which records are available. We agree transfer of access rights, configurations and knowledge from the current provider, with whom we can cooperate during the transition. Missing device access or service information is recorded as a limitation; signing a support agreement does not resolve it on its own.
What happens if the Internet provider is at fault?
+
We check the devices and connections within scope, analyse measurements and logs, and share findings with the provider. We agree contacts, escalation and progress updates for your business. The provider’s repair times follow its own terms and are distinct from our response time.
Does administration include round-the-clock support?
+
Support hours, priorities and response times are stated in the contract. Monitoring can send alerts outside business hours, but 24/7 support and on-call cover require a separate agreement and confirmed team availability. Critical failures, routine requests and planned changes have distinct handling arrangements.
Are upgrades included in ongoing administration?
+
The contract defines routine changes. A firewall replacement, new location, network redesign or Wi-Fi upgrade may require a separate project, budget and acceptance. Recommendations from reviews are discussed with the decision-maker before additional work is carried out.
