How we build IT infrastructure
IT consulting starts with a full audit of your current IT infrastructure: servers, workstations, network equipment, printers and MFPs, licenses, security policies. We record all bottlenecks, identify risks and form a development roadmap for 6–12 months. After approving the plan, we move on to system administration: we configure servers for business objectives, design network infrastructure and structured cabling, deploy Active Directory for centralized account management, set up VPN for remote employees and branches. We install antivirus and firewall to protect against external threats, configure 3-2-1 backup to protect data from loss and ransomware. At each stage, you receive transparent reporting and documentation for all systems. IT outsourcing with ZXY is not a "visiting sysadmin", but a full-fledged IT department at the price of one in-house specialist.
What is included in IT outsourcing
IT outsourcing from ZXY includes a full cycle of company IT infrastructure maintenance. The basic package includes: system administration of Windows Server and Linux servers, configuration and support of Active Directory, group policies and access rights, administration of mail servers (Exchange, mail on Yandex 360, Mail.ru for Business), file storages and network folders, configuration of firewall and VPN for secure remote access, deployment of antivirus protection on all devices, regular updates of OS and application software, 24/7 monitoring of server and service availability, scheduled backups with recovery testing, user tech support through HelpDesk under SLA with a response time of 15 minutes, maintenance of office equipment (printers, MFPs, all-in-ones, plotters), design and installation of structured cabling if needed. For companies with branches, we add the organization of secure VPN tunnels between offices and a unified security policy. All work is carried out under a contract with a fixed subscription fee and SLA.
Launch timelines and response
IT outsourcing launch timelines depend on the infrastructure size and current state. We take a small office (10–30 workstations) into maintenance in 5–7 business days: we conduct an express audit, describe the infrastructure, sign the contract and SLA, register accounts in HelpDesk. A medium office (30–100 seats) — 2–3 weeks: this includes a deep audit, inventory of equipment and licenses, monitoring setup, development of regulations and instructions. A large distributed infrastructure (100+ seats, several branches) — 1–2 months with a phased transition from the current contractor or in-house sysadmin. We fix the incident response time in the SLA: critical failures (server unavailable, mail not working) — from 15 minutes, important incidents (workstation not working) — from 1 hour, minor requests (printer setup, software installation) — from 4 hours. All requests are recorded in HelpDesk, you see the status and resolution time in your personal account. 24/7 support for critical systems is possible.
Why outsourcing is more profitable than in-house
Maintaining an in-house sysadmin costs a Moscow company 120,000–180,000 rubles per month (salary + taxes + vacation + sick leave + workplace + training). And at the same time, one specialist cannot cover all tasks: they will get sick, go on vacation, not have time to urgently fix a downed server. IT outsourcing with ZXY costs from 35,000 ₽ per month for a small office and from 90,000 ₽ for a medium one — and you get a whole team: a Windows system administrator, a Linux administrator, a network engineer, an information security specialist, first- and second-line tech support. Each profile specialist deals with their task, not "a little bit of everything". All specialists are certified by Microsoft, Cisco, and have experience with enterprise-level projects. If your sysadmin quits — the infrastructure is left unattended, knowledge leaves with the person. With outsourcing, there are no such risks: documentation is stored in our base, any team engineer can pick up the task. This is transparency, budget predictability and risk reduction for business.
Technologies and platforms
We work with all current IT technologies for business. Server side: Windows Server 2016/2019/2022 with Active Directory, group policies, Hyper-V, RDS, file servers and DFS; Linux distributions Ubuntu, Debian, CentOS, AlmaLinux for web servers, databases and Docker containerization. Virtualization: Hyper-V, VMware ESXi, Proxmox VE. Network equipment: Cisco, MikroTic, Juniper, Ubiquiti switches and routers — configuring VLAN, QoS, fault tolerance, load balancing. Security: pfSense, OPNsense, Fortinet, Check Point firewalls; VPN on OpenVPN, WireGuard, IPsec; antivirus protection Kaspersky Endpoint, Dr.Web Business. Backup: Veeam Backup & Replication, Acronis Cyber Backup, BorgBackup with encryption and recovery testing. Monitoring: Zabbix, Prometheus + Grafana, PRTG. HelpDesk: GLPI, osTicket, integration with Telegram and email. Structured cabling and engineering systems: design and installation of cable infrastructure, server cabinets and racks, UPS APC and Eaton. We select solutions for budget and objectives.
Guarantees and SLA
We work under an official contract with a specified SLA and financial responsibility. If the incident response time exceeds the agreed one, you receive compensation — this is specified in the contract. We guarantee confidentiality: we sign an NDA, all work with your data is carried out only through secure channels, accesses are issued according to the principle of minimum privileges and are logged. We implement regular backups with recovery testing — if data is lost through our fault, we restore it at our expense. We provide complete infrastructure documentation: network diagrams, server passports, administration regulations, user instructions. If you decide to return the IT function in-house or change the contractor — we transfer all accesses, documentation and comments without problems, ensuring a smooth transition. We conduct quarterly security and efficiency audits: we optimize licenses, offer savings, identify bottlenecks before they become an incident. Transparency, responsibility and long-term partnership are our principle of working with clients in the IT field.
