What Clients Say

‘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.’

Waltham Forest Housing Association

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.
