For when your internal IT team needs senior infrastructure expertise behind them, without the cost of hiring it in-house.
Most businesses reach a point where their internal IT team handles day-to-day server and network management well, but the infrastructure foundations underneath are a different challenge entirely.
Servers, networking, storage, identity platforms and core Microsoft services demand a level of specialist expertise. When something goes wrong at that level, the impact is felt across the entire business.
Nexus Guardian Support is proactive third-line IT infrastructure management, delivered alongside your existing team. We own the foundations your business depends on, giving your internal team the time back to focus on users, while your business can rely on consistent, predictable performance.
We work alongside your team to deliver hybrid and on-prem infrastructure support to protect performance, plan ahead and give you the visibility to make confident IT decisions.
Support with IT budgeting, roadmaps, and alignment with business goals.
Easy access to tickets, documentation, and service history.
Transparent insights into system health, ticket trends, and service metrics.
Your business needs to have the utmost confidence in its third-line IT support service. When you entrust infrastructure support with Nexus, our security posture is as robust as our technical ability.
Every year, Nexus is externally audited to ISO 27001 for information security, embedding a security culture into our organisation that runs through every engagement we deliver, including Guardian infrastructure support.
We hold ourselves to the highest standards in cyber security to provide certified Cyber Essentials Plus third-line IT support, keeping our systems secure and your business’s data and infrastructure protected.
We make knowing how to choose the right IT support for your business simple. Choose Nexus Guardian for unlimited access to enterprise-grade security measures that help safeguard your business against cyber threats, support compliance with industry standards, and give you confidence in the partner managing your foundations.

Your internal IT team is good at what they do. Guardian support provides them with the senior infrastructure expertise, proactive monitoring, and strategic oversight they need to maximise performance without expanding headcount. Stay in control and ahead of the curve.
Nexus has been awarded a place on the G-Cloud 14 framework, offering public sector organisations a streamlined, pre-approved way to access our Guardian infrastructure support.
We aim to fix as many faults as possible on first contact. But, when your internal team escalates an issue, they’ll be talking to specialists who already know your environment inside out, across second-line and time-served third-line engineers.
We complement your existing operations by creating a bespoke solution from our full spectrum of services. Across our entire IT infrastructure support service, we deliver a managed solution that works with you and for you.
We provide our clients with a full IT forecast for the duration of our relationship. Where possible, we forecast all costs for your infrastructure function, providing clarity when budgeting for the future.
Nobody likes being the go-between. Beyond initial IT infrastructure consulting, we’ll deal with your suppliers and vendors, resolving technical infrastructure issues with them on your behalf.
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.
(Most suitable for organisations with 40+ IT users.)
