Active Directory Migrations

Thanks to our rich experiences and our Active Directory Migration Framework, we can succeed where others fail. Unpopular tasks such as consolidating, splitting or restructuring of Active Directory instances are a breeze for us. We are also well aware that these changes have significant implications for enterprise applications and systems. That is why we devote a large part of our efforts to application impact analysis and healing.

In the area of IT security we have many years of experience that we can effectively capitalize on designing or implementing customized security solutions such as Identity management. Within the design itself, we take into account, among other things, the fact that it is not always in the power of the customer to acquire new infrastructure software components and therefore we always try to find the optimal solution using existing resources.
