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.

Quotes from Members

"The graphics and analysis in Microsoft Defender for IoT are very representative."

"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"As a cybersecurity consultant, the best part of Microsoft Defender for IoT is the capability to integrate with other tools such as Microsoft Sentinel and receive real-time alerts from the product."
 

Cons

"Currently, our company has to add the secrets manually, one by one, in Azure Key Vault, which is a tedious process."
"Users should be able to segregate the passwords."
"The slow response from the support team is one of the shortcomings of the solution that needs to be improved."
"It needs to offer dynamic secrets management."
"One of my previous clients was one of the big banks here in the Netherlands and the EU courts have stated that Microsoft Azure Key Vault is not, according to their perspective, secure due to the fact that Microsoft has access to Key Vault."
"It would be great if Azure allowed more third-party vendors into the ecosystem."
"Azure Key Vault is only available for Microsoft services, and it should be exposed to non-Microsoft cloud services, like GCP and Amazon."
"Azure Key Vault takes time to fetch values while integrating it with the code written in .NET format."
"Customer service and support from Microsoft are costly. The execution by engineers is expensive, and the service is neither free nor toll-free, making it less accessible for customers."
"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."
"There are a few limitations with Microsoft Defender for IoT. We raised concerns with the product team because they don't capture all the information regarding command execution or processes executed on certain endpoints."

"We use a pay-as-you-go license for the solution, which is not very expensive."
"The pricing is decent. It has a pretty low price. It is a straightforward cost based on usage."
"You don't need to pay for a license for Azure Key Vault. It is billed on a pay-as-you-go basis."
"There are no extra costs beyond the standard fees, beyond maybe data transfer charges. It's $0.025 per 10,000 data transactions, so it is quite cheap."
"Currently, the tool's monthly licensing costs are around 1,800 USD for all the environments combined, including the production and pre-production environments."
"I give the price of the solution a ten out of ten."
"Key Vault, like every Azure service, has a cost associated with it, but you don't have to spend thousands of dollars to spin up an environment to build a key management system. It's already there."
