The team at Catalyst produced a thorough and very well written recommendation and competitive quote to replace our ageing and low powered server and failing network.

The new server, full cat 6 replacement network with 78+ network points, was installed over a single weekend in our offices, which dates from the Georgian period.

This was a mammoth task, with many walls up to a meter thick! This work would have tested any IT Network company but Paul Nolan and the team worked very long hours over a weekend to ensure our new server and network were up and running first thing Monday morning.

The installation is a first rate job, very neat and tidy. Catalyst engineers have worked hard and with sympathy to make sure period features of the offices were not damaged or affected in any way by the installation. Many of the cable runs were through tight roof and loft spaces and these were undertaken to protect the building.

We have had 100% up time on our new server and network. I can confidently work away from the office for any period of time now knowing the network will not fail and let me and the business down. The team’s in-depth knowledge and support is excellent, should our IT department require assistance and support with the server settings Catalyst simply login, make the required changes but also helpfully talk our technician through what they are doing every step of the way too, so we have knowledge of the issue and how it has been fixed. The level of support, service and assistance, I would say is second to none.

Catalyst always give very good, impartial advice when we require their assistance, being it specifying a new network attached media storage server, adding a new building into the network, or the installation of networked webcams, I am always very happy to listen and make informed decisions based on their guidance and recommendations.

They have been a real support to our business whilst we made the transition to higher level of technology, Catalyst have been key to my work and Rosemary Conley as a business. Their support and services have been a very trusted resource whilst I have been at Rosemary Conley. I can wholly recommend Catalyst.
