Everything Cisilion has done for us has been successful, with all deployments resulting in cost savings or improved performance – in most cases both.

Cisilion showed a great understanding of our business requirements, they also demonstrated expertise in all areas. That gave us great confidence when working with them going forward.

Derek Walklate, Service Delivery Manager at HMV

Cisilion won with the lowest cost and highest quality tender. We were reassured by their extensive knowledge in the Public Sector.

David Reese, ICT Infrastructure Team Leader at Xentrall

Cisilion’s size was able to give us a personal and reactive service. Cisilion initially won the TelePresence project due to their proven track record with previous projects they had deployed for us and their expertise within the field.

Dean Fuller, Security & Networks Operation Mgr at Aspen

Cisilion did a great job with our Microsoft Skype for Business deployment. It is clear they are experts within Collaboration and Unified Communications and this project was delivered within budget and on time.

We really love working with Cisilion. They understand the way the law firm works, they understand the way infrastructure and unified collaboration works.
