The sites of HiComm and GoGuide are our main business tools and any disturbancies in the work of our editors on the backend, as well as any end user access interruptions are critical problems for us. After moving to the Delta Cloud solution any of these issues were gone.

Marian Naydenov

CEO, Prodesgin.

Our impression of Delta.BG is very positive. In the beginning their technical team listened carefully to our requirements and proposed architecture based on our suggestion, but with some additional, real improvements. They invested enough time to answer our concerns and helped us find where exactly the problem lies. During the whole working process, the team demonstrated excellent technical knowledge, sound communication and quick task delivery.
