Environment review
We list servers, versions, licences, services, access and dependencies. We review documentation, overdue updates, backups and monitoring coverage.
Server administration
Linux and Windows administration
We take on agreed Linux and Windows server administration tasks or work alongside your IT team. We manage updates, access, services, backups and monitoring, and document changes and open risks. Before work starts, we agree the ongoing support scope, service hours and response arrangements.
Trusted by
Companies and institutions that need stable IT.
Support shaped around your servers
We start with server roles, applications and the dependencies that matter to your business. Administration can cover on-premises systems, virtual machines, Azure, AWS or a hybrid environment. On Linux, including Ubuntu, Debian and RHEL, we manage web services, databases, repositories, scheduled tasks and logs. On Windows, we manage accounts and permissions in Active Directory, network naming and addressing (DNS/DHCP), file services, web applications (IIS), remote desktops (RDS) and virtual machines (Hyper-V), alongside dependencies involving Exchange and Microsoft 365. We agree responsibilities with your team and application providers.
Services linked to administration
Access, backups and monitoring need to cover the same services. We agree which parts we maintain and who is responsible for the rest.
Active Directory
Employee accounts, groups, delegated permissions and Group Policy (GPO). Reviews of domain dependencies and Entra ID integration.Backup and recovery
Backups of virtual machines, databases, files and system state. Retention and service recovery tests, including domain controller restoration.IT monitoring
Availability, resources, certificates, logs and backup errors. Thresholds and escalation in Zabbix, Prometheus, Grafana or your existing tool.IT outsourcing
Broader support combining server administration, helpdesk and ticket coordination. Scope and responsibilities are set out in the agreement.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 prepare the handover in stages with service owners. Sharing passwords alone does not establish system condition or responsibilities.
02
Plan and urgent changes
We agree priorities, approvers, maintenance windows and rollback conditions. We check critical backups, review access and make agreed changes, checking application behaviour.
03
Support arrangements
We record your tasks and ours, service hours, contact channels, priorities and escalation. We agree response targets, reporting and reviews, including out-of-hours arrangements.
04
Ongoing administration
We manage agreed services, operating system and application updates, monitoring and backups. We review access and risks, document changes and discuss further improvements.
Practical scope
What you receive during support
At agreed intervals, you receive a summary of completed work and decisions needed. Documentation includes exceptions and deferred tasks.
Services, dependencies and responsible people, with availability and resource use. We identify bottlenecks, capacity risks and priorities for further work.
Updates applied, check results, the person approving the change and the rollback plan. Deferred updates have a recorded risk, an owner and a date for review.
Findings on administrator, service and emergency accounts, minimum permissions, multi-factor authentication (MFA) and local passwords. We record approved changes and outstanding exceptions.
A report from agreed backup tests and a service recovery procedure. We compare results with agreed recovery time and acceptable data loss, the RTO/RPO objectives, and identify any unmet conditions.
Controlled changes to live systems
We select safeguards for the system’s role and version, drawing on resources such as CIS configuration benchmarks. We restrict unnecessary services and remote access, and review firewalls and network separation. Everyday, administrator and service accounts are kept distinct; MFA, emergency access and event logging are reviewed. We check updates and configuration changes for application impact and rollback options. We agree resource and service settings aimed at improving performance, then check the effects after implementation. Repeated tasks can be automated with Ansible, PowerShell or Bash. Legacy applications and production systems, including industrial automation, require separate agreement on limitations and a change plan.
Questions about server administration
Can we commission a one-off change?
+
Yes. An intervention, migration or configuration change can have its own scope. Ongoing administration covers agreed recurring tasks, tickets and reviews. Completing a one-off project does not automatically transfer responsibility for later maintenance.
Can you take over legacy servers and applications?
+
We first check versions, update availability and application dependencies. We can plan stabilisation, access restrictions or modernisation. Exceptions and risks need decisions from the system owner; we do not assume every legacy system can be maintained unchanged.
Does monitoring include 24/7 administrator support?
+
Not automatically. Service availability can be monitored around the clock, with SMS or email alerts to named contacts. On-call cover, support hours, response times and repair scope are agreed separately in the contract, taking team availability into account.
What determines the administration cost?
+
Server count and roles, environment condition, tasks, service hours, tools and reporting. We can agree hourly assistance, ongoing support or work alongside your IT team. Rates or a subscription and any additional work are defined after reviewing the scope.
