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.

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."

Cons

"We encountered a few problems where Azure had infrastructure problems like the DMS."
"If multiple clouds are to be used it can be difficult and a third party should assist in the implementation."
"Azure Key Vault has a lot of glitches."
"Azure Key Vault is only available for Microsoft services, and it should be exposed to non-Microsoft cloud services, like GCP and Amazon."
"Inability to access the solution on the phone."
"I would suggest making the user interface a bit more friendly."
"The response time can be improved."
"One area for improvement is the notification system for secret expiration. It would be beneficial if the service could handle this more autonomously, eliminating the need for additional integrations."
"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
"The integration is not as seamless compared to competitors like Palo Alto."
 

Pricing and Cost Advice

"The product is inexpensive."
"The cost of the Azure Key Vault is very high and the pricing model is based on the number of keys that you store and retrieve."
"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."
"The product has good pricing."
"The product costs much less compared to other vendors."
"Currently, the solution's pricing is based on the number of transactions, which is very high in some cases."
"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."
"It is less expensive compared to other competitors."
