Don’t just take our word for it,
here’s what our clients say about us
“3D Design Desktop answered all our problems when we needed to expand. Our team in India love working with it and they never seem to be affected by latency or anything that impacts their productivity. Our designers in Scotland love it too, as now they have more flexibility in their work than ever. We can finally allow our designers the option of working at home on occasion if they would prefer, which is great. As we grow, we anticipate that 3D Design Desktop will underpin that growth and allow us to remain a truly global company.”

“3D Design Desktop from entrustIT has allowed us to unite our three offices better and has provided a centralised location for all our data which works better for us. Now that our 3D CAD applications are accessed from the cloud, we can downgrade our existing local infrastructure, which saves us money long term.
The important thing is that the tell-tale signs that this is a cloud service have been purely in visuals rather than performance stutters. My IT time will move down to training software rather than sorting out problems”

CASE STUDY
Brambletye School
Brambletye School is centred on a large country house on the edge of the Ashdown Forest, in its own woodlands and extensive playing fields. entrustIT began with a large-scale fibre internet rollout throughout the school, filling each building with reliable high-speed internet.
