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.

Integration with existing tools boosts management efficiency
The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong. Often, it just links back to a generic KB article without additional information. When it happens, it requires extra detective work. This issue doesn't occur often but can be annoying.

Quotes from Members

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

Pros

"Stability is very good."
"The most valuable features are ease of use and enabling our clients to manage keys."
"It integrates well with Azure services and is easy to use and quick to provision."
"The integration with other Azure services is one of the standout features for me. It allows us to use secrets from the Azure Key Vault seamlessly without direct interaction.Additionally, the ability to easily mark secrets for expiration and receive notifications is invaluable."
"We use Azure Key Vault to store secrets."
"The access policy feature helps secure content and resources."
"Overall, I would rate the solution a ten out of ten. It is excellent."
"It is a managed service in Azure, you do not have to worry about security other than managing your own identities."
"I believe it is best suited for cloud services and is unmatched by other cloud security solutions."
"It is manageable and integrates with other Microsoft products, which is crucial for me."
"I find Microsoft Defender very effective in vulnerability management and it provides good attack reduction, making it a next-generation protection solution."
"Mainly, it is manageable and integrates with other Microsoft products, which is crucial for me."
"The graphics and analysis in Microsoft Defender for IoT are very representative."
"As a cybersecurity consultant, the best part of Microsoft Defender for IoT is the capability to integrate with other tools such as Microsoft Sentinel and receive real-time alerts from the product."
"Some advantages of Microsoft Defender for IoT are that it's easy to install on any OS, and you can create any custom use cases easily."
 

Cons

"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."
"Inability to access the solution on the phone."
"There's room for improvement in cross-platform compatibility."
"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."
"If the region where the Azure Key Vault data center is hosted goes down, it would be a cumbersome task since our company will have to come up with a different Azure Key Vault and migrate all the secrets or keys into it."
"The slow response from the support team is one of the shortcomings of the solution that needs to be improved."
"I would rate the stability of Microsoft Azure Key Vault an eight out of ten. We use the solution in the data science field. If there is some outage, we did not notice any prolonged outage which would affect our business significantly while working with it."
"It needs to offer dynamic secrets management."
"Customer service and support from Microsoft are costly. The execution by engineers is expensive, and the service is neither free nor toll-free, making it less accessible for customers."
"The primary area that needs improvement is compatibility with the latest IoT technologies."
"Microsoft Defender for IoT is not scalable. If you want to monitor another industrial network, you need an additional server, making it less scalable."
"The documentation for Microsoft Defender for IoT is lacking. There are no clear steps or guidance, and updates are frequent, which adds to the confusion."
"The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong."
"There are a few limitations with Microsoft Defender for IoT. We raised concerns with the product team because they don't capture all the information regarding command execution or processes executed on certain endpoints."
"The only improvement I see is that some detection explanations are vaguely provided by Microsoft, resulting in generic IoT detections that alert me to an issue yet don't specify what's wrong."
 

Pricing and Cost Advice

"The product is inexpensive."
"Currently, the solution's pricing is based on the number of transactions, which is very high in some cases."
"The price of the solution is reasonable for what we are using it for."
"I give the price of the solution a ten out of ten."
"The price of the product is okay for my company."
"The product is neither cheap nor expensive."
"You don't need to pay for a license for Azure Key Vault. It is billed on a pay-as-you-go basis."
"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."
