‘Proficient, friendly, and recommended wholeheartedly’

‘Our staff and students were tearing their hair out in frustration. Intersys staff are proficient, understand the education sector and, most importantly, are friendly and explain everything in layperson’s terms. All of this makes it very easy for us to recommend them wholeheartedly.’

Michael Jarrett, Head of Finance and Corporate Services

‘We have truly levelled up… delighted with Intersys’

‘Our systems are faster and more secure, and we can share and even collaborate on documents with ease. Chat and virtual conference meetings are now built into our systems functionality. We have truly levelled up and we are delighted with Intersys’ services.’

Waltham Forest Housing Association

‘With many of our people now working from home, we wanted a more proactive approach to cyber security, better reliability and more user-friendly IT systems. Intersys conducted a thorough listening and planning exercise, before moving us to a highly secure cloud-based platform. Our systems are now faster, more robust and more secure. We share and collaborate on documents with greater ease. Chat and virtual conference meetings are built into our system’s functionality. We have truly levelled up with an IT system that has markedly improved workflow and productivity. We’re delighted with the Intersys service.’

An exceptional cyber security service

With multiple offices across the globe, cloud-based systems and close relationship with external providers, we realised creating our Cyber Risk Management Framework would require considerable expertise. Intersys did a great job of gathering all the necessary data about our company’s global systems and processes, and then benchmarking it against the expected standards.

I could certainly recommend their service and approach.

The Intersys team stepped in and helped us to design and acquire our new system and managed the expedited separation from GE.  Thanks to them, the entire process was pain free and efficiently managed. Perhaps the greatest compliment I can give them is that none of our clients realised there had been any change in our systems, although every single element was new and created from scratch.

Your technician has been great. Very patient and helpful. He helped me all the way along and didn’t mind explaining in terms I could understand. His good humour was much appreciated too. He really is a credit to your business and yet again I can say I have had a great service from Intersys.

The whole process is highly professional at all stages and made to suit our individual needs.


You and your team’s efforts were outstanding.

FISU, www.fisu.org

It was my first experience with Intersys and from the very first conversation I knew FISU was going to be looked after by an expert with a very professional service. I needed my server decommissioned as it was 13 years old and moving to Office 365 in the Cloud. Jake was fabulous and made everything seem so easy (when I had seriously struggled). I was looking for honest, expertise and I am very glad I found these guys as they delivered on every word. Great job – thank you!

Whites of St Ives – Property Letting

When we started receiving 1000’s of unwanted Mail Delivery System emails and we were going particularly crazy on the day we received 160,000 of them, there was only one place to go for help – Intersys Consultancy. A big thank you to everyone at Intersys. Great service as always!

I would definitely recommend Matthew and his company Intersys. For the last two years Intersys has been providing hosting services and support for my company and Matthew and his team have always been of great help, with a very reliable and personal support whenever needed. What I particularly appreciate with Intersys is the quality of communications with all members of staff, as well as the service delivered.

When your husband deletes the whole content of the desktop he doesn’t use but contains all your work invoices, end of year information, referral letters, triage outcomes and just anything that’s important work wise to do with your business (not his but mine) am I entitled to pour a bucket of water over his Mac, hit him over head with saucepan or both. Wine is the short term answer, Intersys Consultancy is the solution!

CME Media Services Ltd

I have had the pleasure of dealing with InterSys over many years. Matt, Richard and the team at InterSys are always there in your moment of need. I have never hesitated in recommending InterSys to people who require both IT consultancy and Risk management services.

Mach 2 Shipping Ltd

With every ten great things which new developments in IT bring to our working environment, there are usually nine problems which accompany these! Working in hundreds of different international markets here at Mach 2, we cannot afford to be offline at any time of the day, as there will always be one country at work and looking for information or answers from us. And for that very reason we count ourselves very fortunate to have the immediate back-up of Intersys, there to help keep our business alive in times of technological breakdown with its thorough understanding of all our needs!

Alpha, Alent PLC

Working with Intersys we integrated 4 European stencil manufacturing facilities on to single platform, resulting in significant reductions in the Sales Administration resource required to run our business, simpler sharing of our capacity across the 4 sites and automated links to our other business systems… From day 1 the team at Intersys showed excellent commitment and effort in fully understanding our hopes for the system, bringing a pro-active approach by offering input that would enhance the final product at all stages along the way. Their whole team’s approach was open, friendly and sought always to deliver what was best, not just for our immediate needs but with the foundations for future functional expansion built in.

MD: Offshore Marine Management, Offshore Marine Academy, Floating Cable Tank, CAOMM

Running a complex organisation of multiple companies, I need corporate IT services to work with me and to scale with all of my businesses, smoothly and without fuss. Intersys’ Managed Service has been significantly easier to manage, more cost effective and more responsive than the equivalent service from permanent support staff. The skills go far beyond just IT and I know I can trust these guys to keep us running and growing.

the Westminster Foundation for Democracy.

Intersys have exceeded our expectations. The team have been clear about their recommendations, very cost-conscious and a pleasure to work with. They have been key to improving both security and service for our teams.

Alfresco Group PLC

I have been using Intersys for several years now, as my business has grown in size so have my IT requirements. Intersys have supported me along the way with their expert knowledge and know how on system requirements and unrivalled back up support. People have always been on hand at a drop of a hat when required. Speed is of the essence with IT and they certainly provide this – Strongly recommended.


We have used Intersys since 2016 when they were required to install a completely new IT system at our charity. From the outset, we were amazed at their professionalism, friendliness, competence and patience. The system they installed is perfect – they worked around us in really difficult conditions (we are a long way from nice, tidy and quiet offices!). Their ongoing support is incredible – it is so efficient, effective and compassionate (I say compassionate because we often bombard them with ridiculously silly support requests and they are always so patient and caring about our needs and lack of knowledge). We cannot recommend Intersys highly enough. In terms of quality of IT support, they are truly gold standard. We honestly don’t know what we would do without them.

Bowmed Ibisqus

Breaking out a fledgling company from a large multinational pharmaceutical company was difficult enough, however having been introduced to Matthew and his team, the IT and Communications element of the change could not have been easier and trouble free. We have now worked with Intersys for the last 10 years and seen their business grow as we have also grown in our own fields. In all this time, the excellent service at almost any time has never waivered. Many of my staff have to work remotely and it is essential that contact is maintained at all times in order for us to service the hospital sector of the NHS. Intersys give us the support as and when necessary to ensure that we can confidently meet this challenge. In the ever changing I.T. World, Intersys have advised and assisted in us staying at the forefront of technology and providing solutions, an essential for today’s business leaders.
