Featured Reviews

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.
Massimiliano La Camera - PeerSpot reviewer
Provides cost saving and offers device visibility
I think it's a stable solution and don't foresee any problems in the future. It's a leading security platform and is widely used in Italy. This gives them full visibility of all devices, which is often difficult to achieve. IT managers usually lack visibility into all products and security solutions. However, this platform lets customers gain visibility of their entire device environment. I rate its stability an eight out of ten.

"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."
