We are lucky to have a large portfolio of happy customers. Our talented team works tirelessly to help each client succeed in their sector. We’d like to thank those who took the time to share their kind words below.

“Working with Ben on Customer Support has made our IT issues disappear. We never worry about the systems, we just come to work to do the day job.”

Citadel Support Customer

“We’d heard about ‘the cloud’ and ‘hosted’ but never considered it to be an option for us. But after learning about the benefits of a secure digital workspace, requiring no internal hardware infrastructure nor the cost and resources to maintain an on-premise server, the choice to move to cloud seemed the right decision.”

“Citadel offered us a platform for our online CRM hosting, in which it has been a testament to the reliability of the platform as we have only needed to long one support request since migrating to Citadel. That support request involved restoring a backup to recover data, which a user of one of our customers had accidentally deleted. This was handled quickly and efficiently, much to the relief of the user in question!”
