John Stenton, Thrive Homes
We thought we were covered by our MSP, turns out that IT Security is best left in the hands of IT Security Specialists. We were surprised and delighted by how quickly and accurately the Cognisys team got to the root of some of the issues and we feel a good deal safer as a result.
