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.

Product deployment protects assets but needs improvement in system support
I am doing maintenance for Microsoft Defender for Business, and I'm currently working with it. We don't need to use the latest version of Microsoft Defender for Business. We still use the latest virus definition file that Microsoft Defender for Business has automatically updated. We implement a basic update mechanism. Our compliance division manages how many servers and PCs we have and whether those servers have antivirus solutions. I am not certain about how Microsoft Defender for Business helps with AI-driven security strategies. I just use it normally and don't know if it uses AI technology. I rate Microsoft Defender for Business a six out of ten.
