In the modern business world, digitization is no longer a competitive advantage, it is a basic condition for existence. Companies, organizations and businesses, both large and small, manage all of their activities on computer networks. From customer relationship management (CRM), through financial and accounting systems, to sensitive information including trade secrets and strategic plans. However, this complete dependence on technology makes the business sector a favorite target for cybercriminals. Computer attacks are not the preserve of giant companies only; in fact, small and medium-sized businesses are often easier and more attractive targets for hackers. This is due to the misconception that "it won't happen to me" or a lack of dedicated security resources. In the most common work environment in the world, the Windows operating system, strong, dynamic and updated protection is no longer a choice, but an essential insurance policy for business continuity.
