Secret storage and certificate management have been streamlined
I am not on the developer's end. I am primarily the main infrastructure person. I'm not sure what needs improvement. Sometimes, we face issues that the support team is not aware of, necessitating investigation from their end. For example, one of our certificates was not getting deployed, and during that time, the support team was unsure and had to connect with the back-end team for assistance. Improvements can be made in this area, however, it's understandable that not everything can be perfect.
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.
