How quickly we take charge of your request
Just like in our VirtualAssistance support contract model, the response time is selectable based on how critical your systems are: the shorter it is, the higher the priority.
| Response SLA | Best suited for |
|---|---|
| 3 hours | Critical servers and services that cannot afford downtime |
| 8 hours | Workstations and services with a significant operational impact |
| 12 hours | Relevant requests that can be handled within the working day |
| 24 hours | Routine requests and activities that can be scheduled |
It's the same selectable SLA model used in our IT support contracts: we define it together based on your systems, with no hidden costs.
Remote or on-site: how we step in
| Channel | When we use it |
|---|---|
| Remote | Remote support for the most common issues: fast, with no travel cost. |
| On-site | On-site presence when hardware needs replacing or new installations are required. |
Not sure which SLA level is right for you? We analyse your infrastructure for free and help you choose the SLA that best fits your company, with no obligation.

Business IT support is the ongoing service that keeps company computers, servers, networks and software running reliably. It covers preventive maintenance, remote and on-site technical support, IT infrastructure management and rapid recovery when something fails, with one clear goal: minimise downtime and protect your team's productivity.
For more than 25 years, TN Solutions has supported small and mid-sized companies as a B2B system integrator, providing structured, ISO 9001 and ISO 27001 certified IT oversight. On this page you will find a complete picture of our support services, response times, how contracts work, and why hundreds of businesses choose us as their technology partner.
What is business IT support (definition)
Business IT support refers to the technical and organisational activities that keep a company's IT infrastructure operational: workstations, servers, network hardware, backup systems, printers and business applications.
Unlike one-off, break-fix call-outs, managed support takes a proactive approach. Engineers don't simply react when a problem appears; they continuously monitor systems, apply security updates, verify backup status and prevent faults before they turn into operational downtime.
For an SME this delivers three concrete benefits: uninterrupted operations, predictable IT costs and a single, competent point of contact for every technology need, from a single PC to your entire network architecture.
Managed IT support services from TN Solutions
Our IT oversight covers the full lifecycle of your business infrastructure. The main areas we handle are:
- End-user and workstation support: resolving issues on PCs, laptops, operating systems and productivity software through a dedicated help desk.
- Server and systems management: configuration, patching and monitoring of physical and virtual servers, with a strong focus on continuity and security.
- Networks and connectivity: design and maintenance of wired and wireless networks, firewalls and VPNs for both on-site and remote working.
- Backup and disaster recovery: defining backup policies and recovery strategies to protect your business-critical data.
- IT security: perimeter protection with WatchGuard appliances, access management and alignment with ISO 27001 best practices.
Thanks to partnerships with HP, Dell, Microsoft, Lenovo, Synology and WatchGuard, we supply and configure reliable hardware and software with direct vendor support channels. For more complex requirements, the service integrates with our IT consulting and with specialist network support.
Systems administration and IT infrastructure management
Systems administration is the technical heart of the service. Our systems engineers handle the installation, configuration and maintenance of servers, virtualisation environments, domains and domain policies, as well as the integration between the different components of your infrastructure.
A well-managed infrastructure is one that is documented and monitored. That's why we keep a record of each client's configuration, schedule maintenance work and respond promptly to any anomalies flagged by our monitoring systems.
Explore our dedicated systems administration service to see how we structure the management of your servers and corporate network.
Remote and on-site support: response times and SLAs
Many IT issues are resolved in minutes through a remote connection. Our professional remote support lets us act immediately on workstations and servers, with no waiting and no call-out charges, ensuring maximum speed on the most common problems.
When a task requires a physical presence, such as hardware replacement, cabling, network configuration or new installations, our technicians come to your site. We operate a PC lab and repair workshop in Melzo and provide on-site PC support across Milan and the surrounding province.
Response times are defined in the contract's Service Level Agreements (SLAs) and vary according to the severity of the fault: top priorities, such as a server or connectivity outage, are picked up within a few working hours. Every SLA is agreed at activation, so the timelines match your real continuity requirements. For genuine emergencies — a server down, critical infrastructure offline — we also offer a dedicated emergency IT server support service, available even without an active contract.
IT support contracts: how they work and why SMEs benefit
An IT support contract turns unpredictable spending into a planned cost. In return for a regular fee, your business receives a defined package of services: monitoring, preventive maintenance, support hours, guaranteed response times and a dedicated technical contact.
The benefits for an SME are immediate:
- Fixed costs and controlled budgeting, with no surprises on your invoices.
- Priority response ahead of occasional, out-of-contract requests.
- Fault prevention through continuous monitoring.
- A single point of contact for hardware, software, network and security.
Packages are scalable based on the number of workstations, the presence of servers and the level of continuity required. Discover the available options on our dedicated IT support contracts page and let's assess the right configuration for your organisation together.
