This comprehensive approach enables authorized personnel to immediately identify new vulnerabilities and effectively address risk factors present in the network.

5. Configuration Snapshot
Tenable OT Security compares the current and previous device snapshots to gain better understanding of changes within your OT environment. This includes maintaining a full history of changes made to device configurations over time. Furthermore, you have the capability to roll a device back to its previously confirmed good state.
