The Cyber Security Experts Who Provide the Complete IT Package

Intersys offers IT support and services that transform our partners’ operations. It's partly about technical expertise. It's mainly about putting your needs first – and listening.
We offer leading IT security, along with managed support and consultancy services. We bring these services with a single-minded focus on fixing your problems. So you'll see zero emphasis on pushing you kit and services and a full commitment to powering your growth.
This integrity has seen us develop partnerships with clients across a wide range of industries. It’s helped us pick up many industry awards along the way, too. 

Our friendly and trusted approach is backed up by rock-solid cyber security, exceptional in-house talent, and the accreditations and ISO best practice certifications that reveal our credentials as the right partner for organisations of all sizes. It's why heavily regulated industries such as pharmaceuticals and finance make us a first choice, as well as countless SMEs.

We have offices in London, Essex and Cornwall and we service the whole country. 

If you would like to bring a new dynamism to your organisation with expert IT support and services based on transparency, fairness and integrity – and a very strong customer service ethos – then we really should start talking to one another.

'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.
Matthew Geyman, MD Intersys

Why Work with Us?

Working with an IT provider can seem like a big leap. Essentially, you're giving someone the keys to your business. This is why we put our accreditations, awards and experience front and centre. It proves you are getting IT security, IT support and services from professionals with integrity.

The Security Experts

We lead with security. This is our number-one area of expertise, complemented by our other specialist services. If it's your top concern too, you're in the right place.

Your Data: In Safe Hands

Your data is precious to us. It is protected. We are cyber security experts holding UKAS-accredited ISO 27001 certification. We never compromise your organisation.

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.
