They redesigned portions of our IT system that has resulted in lower cost and increase robustness. They provided us with main and backup domain controllers and set up redundancies on files servers between local and cloud servers thus turning them into HA (high availability) and immune to failures.
We have been very pleased with the overall quality of service they have provided us. They proposed savings of at least 40% on our IT expenditure in their proposal, and we have realized more than 40% savings.
