Comprehensive asset visibility and OT operations support enhance risk mitigation
I use Armis for asset discovery and vulnerability assessments of the OT network Armis is easy to use. Very few software solutions have OT capabilities that do not impact OT operations. Its asset visibility is good as well. This comprehensive feature set is crucial for our operations.…

Effective network monitoring with identified documentation improvements needed
The documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion. More detailed documentation with video instructions for tasks would be helpful. The system capabilities are not well-documented either. Importing device names and maintaining a list can be cumbersome, as it requires manual input for a large number of devices. The backup and restore process is limited to GUI for backup but lacks a GUI for restore, though future updates might address this. Sentinel documentation is also poor, with limited guidance available.
