Room For Improvement

Azure Key Vault needs better key rotation, mobile access, integration, interface, cost, vendor support, and disaster recovery features.
Microsoft Defender for Endpoint faces interface complexity, slow detection, high CPU usage, integration issues, and seeks improvements in multiple areas.
My security area wants to rotate passwords every day, every week, or every month, depending on the services.
One of our certificates was not getting deployed, and during that time, the support team was unsure and had to connect with the back-end team for assistance.
The skill level of the support staff is also questionable.
Repeated interactions are necessary due to Level One's lack of tools and knowledge, hindering efficient problem-solving and negatively impacting our experience with Microsoft support.
In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment.

Featured Reviews

Rajthilak BS - PeerSpot reviewer
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.

Has effectively blocked sophisticated attacks and malicious activities while providing excellent support
Microsoft Defender for Endpoint is very good, but one suggestion is that in some products, we may need to configure security-related settings, whereas Microsoft Defender for Endpoint works completely differently, providing automatic recommendations and actions that we may need to perform ourselves. Regarding the pricing of Microsoft Defender for Endpoint, during the last three years, we set up the product and sold it, but we faced difficulties because Microsoft pricing is always the same. For example, whether I purchase Microsoft Defender for Endpoint for one year or for the next three years, the pricing remains constant with no discounts available. In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment. Microsoft should consider this option to remain competitive, but otherwise, everything else is fine.
