Don't just take our word for it — here's what our clients have to say about working with Sun IT.
Sun IT transformed how our practice manages its systems. Since switching to them we haven't had a single critical IT outage. They respond fast and actually explain what's going on — which we never had with our old provider.
Moving our whole firm to Microsoft 365 felt daunting but Sun IT handled everything. Minimal disruption, the team were trained up, and the ongoing support is fantastic. Genuinely feel like we have an IT department now.
We had a ransomware scare at our lettings office and Sun IT was on-site within the hour. They contained it, recovered our data and put proper security in place. You can't put a price on that kind of local response.
