Turnkey office and branch IT setup: a new office that works from day one

Opening a new office or branch means standing up IT from scratch — network, Wi-Fi, domain, PCs and printers, internet and firewall — with one team. Based on ONYX's real projects, here is what it actually takes.

Opening a new office or branch is not just furniture and desks. On opening day, when staff arrive, everything — internet, Wi-Fi, printing, file sharing, email and security — has to already work. In practice, IT is often remembered last, and the launch gets stuck between disconnected providers (one runs the cabling, another sells the hardware, a third delivers the internet). A turnkey approach removes that friction: one team owns the project end to end and hands over an office that is ready to use. This article explains what a new office needs to work from day one, and how ONYX does it in real projects.

What turnkey IT setup actually means

A turnkey model unites every stage — from planning to go-live — under a single point of responsibility. The client is freed from coordinating separate contractors: one project, one accountable team.

ONYX delivers this by combining equipment supply with integration: the required servers, network gear, firewalls and licenses are sourced from real vendors (Cisco, Dell, HPE, Fortinet, Mikrotik, Ubiquiti, Microsoft), then installed and configured by the same team. Instead of buying hardware and being left alone with it, the client receives a working system. Our services and vendor partners are the foundation of this approach.

The core components a new office needs

Every office is different, but the components that form the backbone of a working IT environment are usually the same. Let us go through them in order.

Structured cabling (SCS) and the network

Underneath everything sits the physical network. Properly run copper links, a switching node, labelled ports and, where needed, a fiber backbone — these are invisible later, but their quality determines the stability of the whole office. ONYX's CTO was the lead architect and build manager of the passive network infrastructure for COP29 (UN Climate Conference, Baku 2024) — MDF/IDF rooms, copper structured cabling and the fiber backbone. That level of experience brings the same discipline to an ordinary office project.

Wi-Fi and the guest network

What staff and visitors expect is stable wireless coverage that works in every corner. That requires access point placement based on a site survey rather than guesswork, and the separation of corporate traffic from guest traffic using VLANs. In the CCN Altyapı project, ONYX carried out the full installation of Wi-Fi, printers and PCs across roughly 20 offices — that is, not a single office but an entire network brought up to one standard.

Domain, Active Directory and email

For any team larger than a handful of people, centralized user management matters. A Microsoft Active Directory domain means a single account per employee, folder access permissions, central policies and secure file sharing. In the MobilGroup project, ONYX set up a domain (AD), email, a server room and server for 120 users across 5 branches, connected the network and built a site-to-site VPN between branches — turning all locations into one managed environment.

PCs, printers and workstations

When an employee arrives, the PC should be connected, licensed, joined to the domain and linked to a printer. This seemingly simple part is in fact where the most time is lost, because preparing dozens of workstations to the same standard at the same time takes organization. In a turnkey model, this is planned in advance as part of the project.

Internet, firewall and security

The moment an office goes online, it needs a perimeter to protect it. A firewall filters traffic, isolates the internal network and provides VPN for remote access. ONYX selects either its own Onyx Firewall or solutions from vendors such as Fortinet, Palo Alto and Checkpoint, sized to the project. You can explore our products on this page.

Why one team makes the difference

When a project is split into pieces, responsibility is split too, and the moment something breaks each side blames the other. A single team closes that gap.

Single accountability

One team is responsible for everything from cabling to firewall. If something does not work on opening day, you know exactly who to call.

A consistent standard

All branches are built to the same structure, which simplifies later support and expansion. In the Technicon project, a field office for roughly 90 people, a small server room, the network, SCS and perimeter CCTV were all built to one standard.

Equipment and work as one

Supply and installation are not separate. The right equipment is selected, delivered and commissioned on site — without mismatches or extra waiting.

Support after launch

The job does not end at handover. With a managed IT model, the principle of "you run your business, we run the IT" continues.

How to scale a branch network

Getting the first office right matters, because every later branch is built on top of it. With a single domain, central policies and an inter-branch VPN network, opening a new location is not starting from scratch — it is repeating a ready template.
