System administration and server support for businesses
System administration and support for physical and virtual business servers in Sofia and across Bulgaria: Windows and Linux servers and Proxmox server virtualization (including migration from VMware, Hyper-V and VirtualBox), at the client's office or in our own cloud. Support for a basic file server starts at EUR 50 per month excl. VAT. For virtualization servers, complex systems and specific applications, the price is set after a review. Support includes 24/7 monitoring, updates and response according to the plan. Suitable for companies with or without an in-house IT team or system administrator that want their servers to run without surprises.

What does server support include?
Subscription server support and administration includes 24/7 monitoring, updates, backups with restore testing, protection and documentation. We do not wait for a server to fail: we watch its condition all the time, update it on a schedule and check that backups can really be restored. If needed, we also supply new or refurbished servers sized for your workload and support them as part of the subscription. This gives you server system administration without an in-house system administrator: management of Windows and Linux servers, users and permissions, IP addresses and network settings. Server support also includes incident response: in case of a failure or an attack, our IT team responds within the response time of your plan.

What happens to your systems at night?
Scope of server support
Support is for companies that keep files, databases and business applications on a server and do not want to hear about a problem from their own staff.

24/7 monitoring with Zabbix
We watch your servers continuously with Zabbix: load, free space, disk health, critical services and availability. When something drifts from normal we get an alert and react before the problem stops work. RAID arrays matter most: one failed disk does not stop the server, so without an alert nobody notices until the second one fails.
- Processor, memory, disks and network in real time
- RAID array and disk health
- Tracking of critical services and applications
- Alerts for low free space and unusual load

Updates and patch management
We update operating systems and services on a schedule, so servers do not go for months without critical fixes. We track which systems are updated and which are waiting, and pick a suitable restart window so work is not disturbed.
- Updates for Windows and Linux servers
- Central view of update status
- Planned update and restart windows
- Service checks after updating

Backups and restore testing
A backup nobody has restored is not a guarantee. We set up scheduled backups, watch every job and check regularly that the data can actually be brought back.
- Automated backups on a schedule
- Verification that every job succeeded
- Restore tests for files and systems
- Recovery after a failure, human error or ransomware

EDR and firewall protection
We protect the server with device-level EDR and a firewall that leaves access open only to the services that are needed. This protects data security and lowers the risk of compromise, especially for systems reachable from the internet. EDR is included in the Professional plan and is an extra on Standard.
- EDR protection and response to suspicious activity
- Firewall setup and maintenance
- Access only to the services that are required
- Review of access and permissions

Environment documentation
We document every server: roles, applications, network settings, backups and contacts. When a recovery or a hardware replacement is needed, we do not start from zero.
- Description of roles, services and dependencies
- Backup layout and recovery procedure
- Network settings and access
- Updated after every change

Windows Server 2016: security updates end on 12 January 2027
On 12 January 2027 Microsoft stops security updates for Windows Server 2016, and Windows Server 2012 and 2012 R2 have had no updates since October 2023. A server without updates is an easy target for ransomware and a weak point in a NIS2 check. Windows Server licenses are charged separately.
- Inventory of servers, roles and applications
- Plan for Windows Server 2022 or 2025, or a virtual machine on Proxmox
- Migration outside working hours, with testing and a rollback plan
- Backup checks before and after the migration
- we will review the versions and tell you which ones to upgrade first.

Incident response by plan
Monitoring runs 24/7 in all plans: a stopped server, a full disk, a failed RAID disk or a stopped service is detected immediately. In practice we pick up most requests almost at once and resolve 95% of them the same day.
- Remote: response within 8 hours, no on-site visits
- Standard: response within 2 hours, up to 2 on-site visits per month
- Professional: response within 1 hour, unlimited on-site visits
Which servers we support
We support a single company server as well as whole environments, wherever they run: at your site, at ours, or in both places.

Physical servers
We support physical servers in the client's office or server room: Windows and Linux, file and application servers. We monitor the hardware, update the system and provide backups.
- Windows Server and Linux
- File servers and application servers
- Hardware and disk monitoring
- Planned replacement and migration to new hardware

Server virtualization with Proxmox
We build and support Proxmox virtualization, where several servers run on shared hardware. You use resources better and can extend and recover systems more easily. We migrate virtual machines from VMware, Hyper-V and VirtualBox to Proxmox. Our own cloud cluster runs on Proxmox and Ceph as well.
- Virtual machines with Windows and Linux
- Allocation of CPU, memory and disk space
- Backups at virtual machine level
- Migration from VMware, Hyper-V and VirtualBox

In our own cloud
Virtual servers can also run in our cloud infrastructure in a data center that we design and maintain ourselves. There is no single point of failure: if one element stops, the standby takes over immediately.
- Two core routers and two core switches in high availability (HA) mode
- Everything is duplicated, including power
- Distributed storage (Ceph) with three copies of the data
- Backups at a separate location linked by a direct optical line (dark fiber)
Virtual servers in our infrastructure are offered only to subscription support clients.
How we start and how we work?
Technical review
We review the servers, applications, backups and access, and decide what is critical.
Joining monitoring
We connect the servers to Zabbix and set thresholds and notifications.
Updates, backups and protection
We set up a schedule for updates and backups, plus EDR and the firewall.
Ongoing support
We respond to alerts and requests according to the plan and keep the system healthy.
Portal and improvements
You see the status and requests in the client portal, and we suggest improvements: capacity, replacement, migration.
When does a business need server support?
If you recognize any of the following, it is probably time for subscription support.
Nobody watches the server until it stops
The server has not been updated for months
The RAID array runs with a failed disk and nobody has noticed
You are not sure the backups can be restored
The system runs software whose support has ended (EOL)
A server replacement or a move to virtualization or the cloud is coming
Server support pricing
The price depends on the type of server. Basic file server: from EUR 50 per month excl. VAT. Example: a company with 10 computers and one file server pays EUR 250, 350 or 450 per month excl. VAT depending on the plan. Backup storage on our servers, spare parts and licenses are charged separately.
Basic file server

Frequently Asked Questions
Call usA server is a computer built to run day and night and serve the other computers on the network: shared files, business applications and databases, users and passwords in one place, and backups. A company needs a server when several people work with shared data or applications. For a small office a NAS or the cloud is sometimes enough - we will review your environment before proposing a solution.
From EUR 50 per month excl. VAT for a basic file server. For virtualization, complex systems and specific applications, the price is set after a review of the environment.
24/7 monitoring with Zabbix, updates and patch management, backups with restore testing, a firewall and EDR (depending on the plan), and documentation of the environment.

Yes. We plan migrations with a dependency assessment, tests before and after the move and a clear execution window, with minimal downtime.
We start with a conversation about your needs. We review your environment - computers, servers, network, backups and access - as soon as you wish, before proposing a solution. Within 1 working day of the review we send you a plan and a price, and once you approve, we start straight away: we document the environment, switch on monitoring, take over access and make the first improvements.
Microsoft stops security updates. The server keeps running, but new vulnerabilities stay unpatched. We recommend migrating to Windows Server 2022 or 2025, or to a virtual machine on Proxmox, before that date. We do the inventory, the plan and the migration outside working hours.
Yes. We support Active Directory, group policies, users and access rights, DNS and DHCP on Windows Server, including when an employee joins or leaves.
Yes. We support the server, the operating system, backups and access. For the application itself we work together with its vendor, so it is clear who is responsible for what.
Backup storage on our servers, spare parts, licenses (Windows Server, Microsoft 365) and a virtual server in our cloud are charged separately. Labour for hardware repairs is included.
EUR 250, 350 or 450 per month excl. VAT depending on the plan, for 10 computers and one basic file server. We confirm the exact amount after a short review of your environment.
We take care of the servers and everything around them: users and permissions in the domain (Active Directory), group policies, shared folders, backups with tested restores, updates, 24/7 monitoring and documentation of the environment. If you also have computers, we add them to subscription computer support so you have one contact for everything.
