Borders and barriers are becoming commonplace in Сyber security. In our time, when choosing a solution, the first step is to clarify the issues of data transfer and storing, as well as a need for the system to connect to cloud services. The possibility of effective functioning in an “isolated“ environment is no less important than the functionality of the solution. This imposes limitations on the choice of the Cybersecurity Strategy for businesses and organizations. The presentation will consider the most important factors that must be taken into account when forming the Cybersecurity Strategy. Among them, such as the willingness to order external expert services, including cyber insurance, using of Threat Intelligence and analytics on APT, deployment of solutions with an architecture that reduces the risks of data leaks and the use of non-declarative capabilities. The right approach in building the Cybersecurity Strategy is, as always, in finding a balance between an open system, with active use of managed services and cloud sources, and completely isolated from external sources.
