CST have been nothing but outstanding.  The pace of digital progress we have made in the last two years has been down to CST.  With their new structure in place, we can consult with our CST Success Manager on strategy, build and develop our digital infrastructure with their on-site engineers and troubleshoot issues quickly and effectively with their remote team.  CST listen to our requirements and know that what we need is unique to everywhere else.

Regional Director EMEA - Omega World Travel
CST has been supporting Yours Clothing for 10 years and has played a key role in ensuring our IT operations run smoothly across our head office and all our stores, providing both onsite and remote support to meet our business needs. Initially CST completed a full nationwide roll out of new Meraki firewalls, access points, including SD WAN setup for every existing store, at the time this was around 90 stores. This was completed over several weeks, with multiple engineers each day visiting several locations to complete the upgrades. Since then, we have acquired several other brands, stores, and warehouses to expand our operations. We now have around 160 stores nationwide and with each new store opening, CST has provided invaluable support.

We are very grateful to CST for their highly capable support and advice over the last few years. They do a great job of managing and maintaining our servers on a long-term contract. However, they have also been impressively flexible and responsive when we have needed projects completed or problems solved, even at very short notice. First class service – thank you!
