Have addressed compliance challenges but still struggle with seamless integration of certificate issuance between environments
In terms of Azure Key Vault improvements, we have to compare the competitor. If we consider AWS, our bank has Microsoft PKI, which is a Microsoft product, for the entire digital certificate infrastructure. Even in the cloud, when it is AWS, the internal certificates are MS PKI. When we had a problem, users had to come to on-premise to get a certificate and import it to AWS Certificate Manager and assign it. We wondered why we could not issue the certificate directly from the cloud for cloud users. There was a simple way in AWS. They have a Private Certificate Authority (PCA) and Amazon Certificate Manager. Private Certificate Authority issues certificates to Amazon services. They also provide Amazon Certificate Manager to store and deploy certificates. These are two neat components - one is an issuer and another is storage and deployment solutions for certificates. With PCA, I can directly enable it and get certificates from AWS itself. AWS can issue SSL/TLS certificates if you enable it directly. If you consider Azure, it is not very clear. Even the naming convention, Key Vault, might not suggest that this is a PKI or certificate manager. You cannot issue certificates directly. They have app certificates and did not have a clear-cut certificate management solution in the cloud when I worked at that time. I am not sure whether they have updated Azure Key Vault as a full-fledged PKI solution now. From what I saw, it was not a full-fledged PKI solution. We are not majorly using Azure Key Vault because it is only for storing secrets. If some solutions can provide guidance on how we can maximize leverage, we can immediately look forward to doing that. We already have some business problems we want to solve. While our primary focus is AWS, many of the services such as ADO are running on Azure, and the secondary services are growing bigger.

Quotes from Members

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

Pros

"It is easy to generate, easy to use, easy to integrate, and very cost-effective."
"It offers encryption with specific algorithms for better management."
"The most valuable features are definitely the alerts."
"The solution has an import dashboard where we can import the certificates or create new certificates."
"With Azure Key Vault, we can generate our own keys and then import them inside the system, which provides a higher level of security than provider-managed keys."
"One of the most valuable features of Microsoft Azure Key Vault is its ease of use."
"The platform has a valuable feature for seamless integration."
"The most valuable feature of the solution is the search for secrets feature that we use to store our passwords and connection strings."
"All its features are really valuable. It's really well thought-out. It's a complete turnkey solution that has all the concerns taken care of, such as access control and management. You can use it in infrastructure as code to create key vaults, APIs, PowerShells, CLIs, even Terraform."
"The tool is highly secure and very easy to manage."
"It helps me increase my security posture and assists with regulatory and compliance requirements."
"The GUI was quite easy for me to use."
 

Cons

"The AWS Certificate Manager's technical support team is sometimes unavailable."
"One potential improvement could be enabling the extraction of the certificate as a file to be used outside of AWS, even with an additional charge."
"Maybe more integration with third-party certificate authorities would be useful."
"Currently, there is no option to customize beyond the default settings, and it would be beneficial to have the ability to customize certificates to fit specific requirements."
"The whole problem of password rotation could be improved. My security area wants to rotate passwords every day, every week, or every month, depending on the services."
"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."
"Azure Key Vault has a lot of glitches."
"Sometimes, we face issues that the support team is not aware of, necessitating investigation from their end."
"Users should be able to segregate the passwords."
"The solution's usage can be a little better from the user interface point of view."
"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."
"Azure Key Vault is only available for Microsoft services, and it should be exposed to non-Microsoft cloud services, like GCP and Amazon."
