In the process of system optimization we inspect the current system according to various criteria from security to efficiency to the harware and software elements of the system to data security to the control of data access to saving and virus defence solutions. The point is to improve or replace any poor elements. In the choice of new applications the main aspect is the needs of the client, often shaped by in-house regulations, standards and budget limits. Often the client may already have solutions for a function but they may not be installed appropriately or may not be secure enough. Our work is based on consultant and system engineer competences. For new contract clients any work related to optimiziing systems is provided free of charge.
