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.

Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Quotes from Members

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

Pros

"A high level of security."
"I would say it's granular controller who can access them."
"The solution's most valuable features are reusability and safety."
"The solution uses the encryption technique to store the secret information data that uses EPCE. There is also one feature that monitors Azure Key Vault."
"I find the simplicity of key management to be the most valuable feature. Key management has always been a difficult function to do, especially in the cloud premises. Azure Key Vault provides you with a mechanism for managing keys, without having to worry about protecting secrets is valuable."
"The centralized storage and secure storage are features we like."
"Among the features that have helped improve our security posture are storing secrets in a secure location to create a trusted situation, trusted resources, and incorporating identity access management so that we know who has access to what."
"Technical support is helpful."
"It seems to be better at protecting from cyberattacks."
"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."
 

Cons

"If you check the capabilities of other key management services across Amazon, HashiCorp, and Google, there are features that Key Vault doesn't have. It could be the case that when you use Key Vault, you might be forced to use a third-party solution to get certain services. If those services could be included in Key Vault, there would be diminished reasons to go for a third-party key management system."
"If multiple clouds are to be used it can be difficult and a third party should assist in the implementation."
"I would suggest making the user interface a bit more friendly."
"Users should be able to segregate the passwords."
"The product must provide AI features."
"The voucher access policy can be improved by configuring it based on groups, rather than just applications or users."
"I would like more code examples."
"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."
"With Microsoft, support is always crazy, it's not easy to get support."
"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
 

Pricing and Cost Advice

"Pricing is quite reasonable and support is included, although premium support is available for an additional fee."
"We use a pay-as-you-go license for the solution, which is not very expensive."
"It is a cheap option."
"Azure is cheaper than CyberArk... CyberArk is good, but it's quite expensive."
"The product is neither cheap nor expensive."
"The product is affordable, in my opinion."
"The price of the product is okay for my company."
"The pricing is decent. It has a pretty low price. It is a straightforward cost based on usage."
