Our Expertise

Security & Protection






The IVISEC™ system was designed with the emphasis placed on the ability to integrate any technology or system without limitation. Each technology is a source of information which is processed by the system.


Information received from the integrated technologies is categorized and stored as notifications and then it is forwarded to our system for further processing./p>


Each notification is processed and evaluated by configurable conditions and rules, which conclusively define system responses from simple storing to the creation of new events. All occurring events are forwarded to client stations for processing.




The system can react to incoming notifications with automatic responses such as implementing preset actions, or, based on received notifications, it can offer a selection of actions which the user can choose from and manually implement.


When a user is solving an event, the system can guide him step by step with a preset workflow. The workflow defines possible states for each type of event and the process by which such events can be solved.


The history of received notifications and user actions within an event can be further analyzed and evaluated thanks to advanced reporting tools.
