We will guide you through certification and help you maintain it year on year. Greendale Group achieved Cyber Essentials certification with our support.
Devon organisations get proactive monitoring, faster response times, lower cyber risk and a technology plan that holds up as they grow. Our IT services cover the whole county from a single team, so nothing falls between providers.
Our IT services in Devon cover the systems your business runs on day-to-day, and the planning that keeps them fit for purpose as you grow. You can take the lot as a fully outsourced IT department, or pick the services that fill the gaps around an internal team. Here is what that includes.
Managed IT support with 24/7 monitoring, unlimited remote and on-site help, patch management and a dedicated contact who knows your setup.
Microsoft 365, Azure, SharePoint, and Teams setup, migration, and ongoing management, so your Microsoft environment works as one unified platform rather than several disconnected tools.
Cyber security in Devon is no lighter a job than it is in London. Our clients here face the same phishing, ransomware and supply chain risk, often with smaller internal teams. We are ISO 27001 certified and run a 24/7 managed Security Operations Centre, alongside vulnerability scanning and penetration testing.
Data backup and recovery covering files, servers and Microsoft 365, plus business continuity and disaster recovery planning, so you know exactly how long it would take to get running again.
IT infrastructure management and third-line support that works alongside an in-house team, handling incident escalation, vendor liaison and the problems your internal staff do not have time for.
Strategic IT projects delivered end to end, including VMware migration, office moves, hardware refreshes and infrastructure upgrades. Your vCIO plans the sequence so the work lands with minimal disruption to the working day.
Managed support is one part of a much wider offering. Our IT services in Exeter cover everything your business relies on day to day, including Microsoft 365 and Azure cloud services, cyber security, data backup, infrastructure management and strategic planning. You choose the level of service that fits, from a fully outsourced IT department to specialist services that sit alongside your internal team.
Because the same local team delivers every service, nothing falls through the cracks. If a security review shows your backup strategy needs attention, or a cloud migration highlights a training need, the same people see it through from our Exeter head office.
For over 25 years, businesses across Devon have trusted us to deliver reliable, proactive security-led IT support — from reducing cyber risk and setting up Microsoft cloud systems, to keeping day-to-day systems running smoothly. See for yourself what our clients have said about their Nexus experience:

When a problem requires hands-on attention, our engineers travel to your site to address hardware failures, network issues, and infrastructure changes. On-site response times are agreed with you based on travel distance.
24/7 monitoring, automated patch management and vulnerability scanning to catch technical issues and cyber risks before they affect your operations.
Our IT consultancy in Devon gives you senior technical input at the point where decisions get expensive. Through our vCIO service you get a named senior consultant who joins your planning conversations and owns your technology roadmap, without you carrying an IT director’s salary. That covers hardware replacement budgets, cloud migration planning, certification and infrastructure reviews ahead of growth.
We support businesses right across the county. Some of our locations have their own pages with local details, response times and case studies:
We also support organisations in Torquay, Newton Abbot, Barnstaple, Exmouth, Tiverton, Tavistock and across both North and East Devon.
Our head office is at Vale House, Pynes Hill, Exeter. We support businesses across Devon from there, with engineers travelling to sites throughout the county.
Nexus is on the G-Cloud 14 framework, which makes procurement simpler for public sector organisations in Devon. We work with schools, housing associations, and local government, alongside private-sector clients.
Yes. Our managed IT services cover the whole county, including Barnstaple, Bideford and the surrounding area. Remote support is identical wherever you are, and we agree on on-site response times with you based on travel distance.
Yes. Many Devon organisations use us for third-line infrastructure support, cyber security and project work while their internal team handles day-to-day requests.
A vCIO is a virtual chief information officer: a senior technology advisor who works with you part-time rather than as an employee. You get input on budgets, roadmaps, and major decisions without carrying an IT director’s salary. It suits Devon organisations that have outgrown a basic helpdesk and are facing decisions with real cost attached, such as a cloud migration or a hardware refresh across multiple sites.
Consultancy can be included in a managed support package on a per-user, per-month basis, or quoted as a standalone piece of work. We will give you a fixed price before anything starts. Get in touch for a quote.
Every business is different and so are its IT challenges.
Whether you’re exploring how to improve cybersecurity, strengthen backup and continuity, or get more from your Microsoft 365 environment, we’ll help you identify where to start.
Our consultants will take the time to understand your setup and share clear, practical recommendations. No jargon, no hard sell.
Simply complete the form and we’ll be in touch within 24 hours.
““Nexus didn’t just turn up with a cookie-cutter approach.
They took the time to assess our setup and designed a solution tailored to how we work.”
ICT Assistant Manager, Tamar Crossings
