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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Technical support is helpful."
"The solution's technical support is good. My company received support from Microsoft whenever we needed it."
"I would rate Azure Key Vault 10 out of 10."
"The most valuable feature is the ability to store secrets securely and encrypt them. It is pretty easy and straightforward to use."
"Azure Key Vault is very affordable, with charges of less than a dollar for over ten thousand keys."
"We only use the basic features and those are the ones that have the ability to tie into the app, the secrets, and the passwords and encrypt them."
"It is a managed service in Azure, you do not have to worry about security other than managing your own identities."
"The product's integration capabilities are good."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It seems to be better at protecting from cyberattacks."
 

Cons

"Azure needs to provide versions of Key Vault that are suitable for different sizes of companies."
"Sometimes, we face issues that the support team is not aware of, necessitating investigation from their end."
"The response time can be improved."
"The slow response from the support team is one of the shortcomings of the solution that needs to 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."
"The big problem with Azure Key Vault is key rotation. We haven't found a good way to synchronize the credentials between the databases and Key Vault."
"If I consider how some people complain that a solution to store information should be available at a low cost, I would say that Azure Key Vault's price should be made cheaper."
"I can see that other people are doing the infrastructure as code, they are able to easily manage and cycle their passwords as needed using their own interface they created. It would be nice if Microsoft provided more guidance in that area."
"The integration is not as seamless compared to competitors like Palo Alto."
"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
 

Pricing and Cost Advice

"Currently, the tool's monthly licensing costs are around 1,800 USD for all the environments combined, including the production and pre-production environments."
"It is less expensive compared to other competitors."
"You don't need to pay for a license for Azure Key Vault. It is billed on a pay-as-you-go basis."
"The product is neither cheap nor expensive."
"Currently, the solution's pricing is based on the number of transactions, which is very high in some cases."
"We use a pay-as-you-go license for the solution, which is not very expensive."
"I find the pricing of Azure Key Vault to be reasonable."
"Azure Key Vault is expensive."
