Jerry O'Connell

Senior Manager International IT, FireEye

I had some previous experience with Steve and his team at QCIS and from the get-go I was keen to get these guys on board, as I knew they were an outfit I could trust and truly partner with. We gradually phased them in on various key projects until finally we cut ties with the incumbent and QCIS became our primary partner. I am delighted to say it has been one success story after another and I can’t recommend these guys highly enough. They provide a top-class level of service with a personal touch. They have become a true trusted partner who continue to share in our success. It is always reassuring to know they have got your back 24/7, even at extremely short notice”
