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.

Pros

"It is easy to generate, easy to use, easy to integrate, and very cost-effective."

"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 offers encryption with specific algorithms for better management."
"AWS Certificate Manager provides central control of certificate lifecycle management, which helps to improve security."
"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."
"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."
"It provides a secure and centralized location for managing and protecting sensitive information, making it an essential component for enhancing the security."
"The tool is highly secure and very easy to manage."
"The most valuable features are ease of use and enabling our clients to manage keys."
"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."
"The integration management of access to Key Vault is beneficial for me."
"The product's integration capabilities are good."
 

Cons

"Better reporting features would be beneficial."
"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."
"Better reporting features would be beneficial."
"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."
"The AWS Certificate Manager's technical support team is sometimes unavailable."
"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."
"We've experienced issues with configuration."
"Sometimes, we face issues that the support team is not aware of, necessitating investigation from their end."
"The solution needs to improve its cost."
"They should improve its policies, which sometimes reapplied but don't sync properly between the Key vault and the role-based access. When I put some roles on the user side, it sometimes misses the end data to secure."
"There's room for improvement in cross-platform compatibility."
"The integration with Thales HSM is complex and is not out-of-the-box. Uploading the keys was quite a tedious process."
"Currently, our company has to add the secrets manually, one by one, in Azure Key Vault, which is a tedious process."
