The security business unit of Omniaelectronics is a team of experts who have been working in this field for more than twenty years and gained experience in high – tech multinational companies and consulting firms. The capability of this winning team is a “holistic” approach to the logical security, today more commonly defined “cybersecurity”. This allows us to understand what is really not secure in the ICT environment of a company, starting from a very simple and immediate concept: if we compare a system to a chain, and measure the level of security of the whole chain, we will have to consider that the level of security is always equal and not higher than that of its weakest link.
