Cyber Threats Database with Computer Virus

Free Trial


The database contains information on servers, their locations, connections to other servers, and when many viruses are detected on them.


  • Visually see how a computer virus infects servers over time and how it spreads from server to server across large geographical areas.
  • Illustrate how Sentinel Visualizer is integrated with Google Earth to see geospatial and temporal data dynamically.
