Have experienced several challenges while managing certificate lifecycle processes
The renewal function and automated certificate renewal are very helpful for our operations. AWS Certificate Manager provides central control of certificate lifecycle management, which helps to improve security. It streamlines the process and reduces human error. I use ACM Private Certificate Authority for additional security measures. I see benefits of using AWS Certificate Manager in integration with AWS for secure data transmission. I see a positive impact in managing SSL and TLS certificates, which simplifies compliance and reduces risk.

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 offers encryption with specific algorithms for better management."
"It is easy to generate, easy to use, easy to integrate, and very cost-effective."
"The most valuable features are definitely the alerts."
"AWS Certificate Manager provides central control of certificate lifecycle management, which helps to improve security."
"The solution has an import dashboard where we can import the certificates or create new certificates."
"It is a managed service in Azure, you do not have to worry about security other than the access, and the vaults themselves are inherently secure."
"The security on offer seems to be quite good."
"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."
"The most valuable feature is the ability to store secrets securely and encrypt them, and it is pretty easy and straightforward to use."
"With Azure Key Vault you have something that is free, enterprise-level, global, and it just works."
"We use Azure Key Vault to store secrets."
"It integrates well with Azure services and is easy to use and quick to provision."
"I am satisfied with the product overall."
 

Cons

"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."
"Better reporting features would be beneficial."
"The AWS Certificate Manager's technical support team is sometimes unavailable."
"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."
"Maybe more integration with third-party certificate authorities would be useful."
"However, if you're not looking to have your application tied to one cloud provider, then you should stay away from this solution."
"Azure has great documentation, but I would like to see more use cases pertaining to specific industries. For example, case studies on how to use HIPAA compliant solutions in the healthcare industry or how to use PCI compliant data analytics solutions in the financial technology industry would be helpful."
"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 voucher access policy can be improved by configuring it based on groups, rather than just applications or users."
"Many times, the first round of support itself will fail, and they will bring some more competent people in the subsequent support. So it gets into a hierarchical mode. By then, we will lose a good amount of time. The technical support needs improvement."
"The solution does not allow you to integrate with XML parties if it is not inside Azure itself."
"Users should be able to segregate the passwords."
"Azure Key Vault is only available for Microsoft services, and it should be exposed to non-Microsoft cloud services, like GCP and Amazon."
 

Pricing and Cost Advice

Information not available
"The product is neither cheap nor expensive."
"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."
"The product has good pricing."
"Pricing is quite reasonable and support is included, although premium support is available for an additional fee."
"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."
"Azure Key Vault is expensive."
"You don't need to pay for a license for Azure Key Vault. It is billed on a pay-as-you-go basis."
"Currently, the solution's pricing is based on the number of transactions, which is very high in some cases."
