A protective DNS is the best way to keep everyone secure, no matter what device they use and what connection they are using.
Given that Railway Company Slovakia covers the whole country with hundreds railway nodes, it needs to constantly ensure the security of both the core team, technicians in the field, and office employees in the entire territory.
This situation required a security layer which operates on the network level covering all the devices without the need to constantly check and maintain any software. Also, it was vital to protect technicians and other employees who take care of the railways in the field.
