Stem Systems, founded in 2004 by Stephen McLoughlin, bring a blend of experience in legacy systems, cloud, software development and automation to implement tailored but highly standardised IT solutions for our clients.

Based in Mallusk, we service public and private sector clients across the UK and Ireland.

We combine our vast experience of on-premise IT solutions with a cloud-first approach. This rounded knowledge gives us an edge when transforming and migrating existing systems, but most importantly, standing over the implementation. We are engineer-led and strive for the best technical solutions for every one of our clients.

Stem Systems has been providing managed IT services to its customers since day one – over 20 years later, it is still the base on which our various offerings are built. Our solution stack is additive – this is actually reflected in our branding, where we may start a customer relationship with one service offering but soon accompany this with layered security, hosting and voice options for example.

Our Client Base Encompasses…

NI health trusts
UK- and EU-based PLC’s
Recognised names in hospitality, legal, medical, accountancy, charity, manufacturing, dental, construction, haulage and retail sectors.

Well-Rounded Solutions

We bring the best possible balance of productivity and security to ensure your systems are available to serve you at all times but protected accordingly.

Microsoft Azure

Our speciality is in delivering server-less, fully managed, scalable hosted desktop environments with Azure. Customers have less hardware to manage, improved security of data and seamless, uncompromised remote working. 10 years’ experience in Azure means we can price it, build it, migrate to it and support it effectively - from 10 users to 100+.

Cyber Security

The security of your data is our utmost priority. We have a proven track record of ISO 27001 security-compliant IT deployments on behalf of select customers.

In-house IT

As an outsourced managed service provider, in-house IT teams also enjoy working alongside us for guidance, project work and additional resource.

Customer-Centric IT Support: Minimizing Pain Points, Maximizing Trust

Our support model of fully managed cover encourages us to minimise the pain points of your day to day IT function. These pain points thereby become a problem for us too, not a cash cow. You’ll get advice from engineers, not business development executives, on technical answers to these problems and a solution that works best for both sides. Customers appreciate our amicable, straightforward approach; in light of this, an exceptionally high percentage of our business today has been from referrals within our existing client base.

Our Clients

Who We Work With

Stem Systems systematically managed each of our eight sites, integrating them seamlessly into a unified system. Remarkably, there was no downtime reported from any of the plants, and numerous long-standing support issues were resolved during the process. We required dependable support both immediately and in the long term to ensure the success of the changes implemented, and Stem Systems exceeded our expectations. I would highly recommend Stephen and his team to anyone.

David McKee,

CTO

We had an aging VMware server estate and growing IT support needs, with multiple offices and remote workers across Ireland. Stem quickly migrated our SAP ERP, file shares, and apps to Azure, removing all servers in under six weeks with no downtime. A few days later, we cleared our server cabinet. Now, I manage laptops with Intune, and we access programs anywhere without a VPN.

Brian Aston, IT & Operations Manager,

Laydex Ireland

MMW are going through an exciting period of growth and it's great to have the technology to underpin this and grow with us. We are serving an ever-increasing client base and Azure gives us the confidence that we can be available for them.
