IT Support That Keeps Your Business Moving
Sentinel Infrastructure provides managed IT support for SMEs across the UK, so your team spends less time on tech problems. You deal with engineers who know your setup, and critical issues get a response within 15 minutes during business hours.
What's included in managed IT support
Our managed IT support packages cover the day-to-day, like helpdesk calls, new device setup, and proactive monitoring. They also cover the planning side, including disaster recovery and advice on where your IT goes next.

- On-site support when needed
- Proactive monitoring so we catch problems before they cause downtime
- New device setup and user onboarding
- Software installation, licensing, and updates
- Network management and troubleshooting
- Antivirus and endpoint protection management
- Data backup and disaster recovery planning
- IT strategy and technology advice
Access a full team at a fraction of the cost
Most SMEs don't need their own in-house IT team, and paying for one is expensive and hard to predict. Outsourcing to Sentinel gives you a full team of qualified engineers. You don't have to recruit or manage them, and there's always someone to cover when one of them is off.
Predictable Fixed Cost
The helpdesk, monitoring, on-site visits and proactive management are all covered by a fixed monthly fee.
A Full Team Behind You
Access multiple engineers with different specialisms rather than relying on a single in-house generalist who can't be everywhere at once.
Faster Resolution Times
Because we're monitoring your systems, we often spot a fault before anyone reports it, and a dedicated helpdesk means the problems your staff do raise get fixed faster.
Up and running in four simple steps
Free IT Audit
We review your current setup, identify any gaps or risks, and understand your business needs.
Proposal
We recommend the right support plan for your business, clearly priced with no hidden extras.
Onboarding
Your team carries on working as normal while we do all the technical setup.
Ongoing Support
As soon as you're onboarded, we start monitoring your systems, and the helpdesk responds quickly whenever your team needs it.
The team at Sentinel had our new office network set up and every member of staff onboarded in a single afternoon. Genuinely impressive.
