A Physical Security Management System (PSIM) or in German - Gefahrenmanagementsystem (GMS) - is a software for efficient security management in properties, buildings and facilities. Via a multitude of interfaces, it records the statuses and enables the control of security-related systems, such as access control systems, video surveillance systems, intrusion detection systems, and many more. Depending on the application, such a system can be used to arm/disarm intrusion detection areas, open/lock doors, trigger fire alarms. Etc.

PSIM systems are particularly widespread in companies with increased or particularly high security requirements. They are often used by operators of critical infrastructures such as energy suppliers, network operators, water suppliers, airports, etc. ...
