Too often, IT support looks like this:

  • Overpromising and underdelivering.
  • Few high-level technicians.
  • No single point of contact.
  • Lack of cyber security expertise.
  • Too much outsourcing.

We do things differently...

In 1996, Intersys was founded on an ethos of solving problems, not making sales. This has been the backbone of our company ever since. We now help SMEs, blue chip companies and highly regulated industries with the same ‘service not sales’ integrity. People say we’re different from the competition. Very different. In a good way.

This is IT Support from Intersys:

  • Consistent delivery. Your IT provider will show up day in, day out, according to rock-solid service level agreements (SLAs).
  • Great customer service. You’ll talk to someone trained in technical skills AND customer service, the two pillars of solid IT support.
  • Familiar faces. Our people stay with us – and you – for the distance.
  • Everything IT. Get high-level expertise in security, consultancy and support – as a complete service or to augment your in-house IT.
  • Protection from criminals. Shut out the growing cyber security threat with help from our specialist security division.
  • Serving all of the UK – We have head offices in London with branches in Essex, Cambridge, Cornwall
    and Scotland.

Matthew Geyman

'We focus on serving our clients with diligence and integrity – and they keep coming back'

From the very beginning, I started the company because I was an IT nerd – not a salesman. It’s always been my view that if we focus on serving our clients with diligence and integrity, the rewards in our own business will come from doing the right thing. We are not an IT sales organisation. Every innovation or strategy we introduce is about powering our clients forward with great IT. This is complemented by fair and transparent pricing and a strong customer service ethos. It’s why clients keep coming back to us year after year.

How We’ll Find the Right IT Solution for You


What’s the situation?

What do your processes look like? What tools do you currently use? This information-gathering is key to understanding how you currently work.

What’s the problem?

We’ll talk to you about the impact of your current processes and tools. Perhaps communication isn’t good, or you can’t make effective use of data?

What's the implication?

We’ll drill down and look at how issues with your tech are affecting performance. How much time is wasted? How many deadlines missed?

What’s the solution?

Only now do we start to match your challenges with a bespoke solution. It’s a service-not-sales approach that is always looking for effectiveness and value.

Certified, Trusted, Reliable

We partner with leading tech providers and industry bodies

Common Questions Answered

How do I know I can trust you with my IT?
Because we have the experience, integrity and recommendations to prove it. IT companies come and go very quickly, but Intersys has played a prominent role in the industry for 25 years because we have a reputation for treating our clients’ IT with diligence and discretion. This is backed up by our accreditations to the highest industry standards – including ISO 27001 certification, an internationally recognised accreditation for information security. Finally, you can read testimonials from long-standing customers who come back to us again and again because they know that their IT is secure with Intersys. It’s the reason why we provide IT services for some of the most security- conscious sectors in the world, including life sciences and education.
We have our own in-house IT. How’s that going to work for you?
Our approach is very much about partnership. We can work with your own IT teams to provide either a holistic upgrading of your systems, or more targeted improvements. In either case, we will work closely with your people to ensure they are on board with the process and trained in any new processes or tools where necessary. Our team is made up of great communicators who will explain their rationale for any suggested changes and support your team all the way.
I’ve had bad experiences with IT businesses before – what makes you different?
Unfortunately, this is the reality in our industry. We have seen businesses choose very competitively priced IT providers – only to discover their ‘partner’ is more focused on selling them services than finding solutions. We like to make this point very clear: we are not an IT sales organisation. When our MD Matthew Geyman founded Intersys, he came from IT, not sales. We are IT people through and through and everything we do for you is through the prism of finding IT solutions. Please, do pick up the phone and give us a call. We’ll put you through to one of our experts and you’ll quickly realise you are talking to an IT person, not a salesperson. It’s this alone that has reassured many clients we have a very different ethos than far too many rivals.
