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.…
William Tuleja - PeerSpot reviewer
Integration with existing tools boosts management efficiency
The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong. Often, it just links back to a generic KB article without additional information. When it happens, it requires extra detective work. This issue doesn't occur often but can be annoying.
