Room For Improvement

Azure Key Vault needs better key rotation, mobile access, integration, interface, cost, vendor support, and disaster recovery features.
Microsoft Purview DLP needs better integration, improved UI, enhanced AI features, cost-effective licensing, and better language support.
With PCA, I can directly enable it and get certificates from AWS itself.
It would be beneficial for me to have a more robust desktop interface for Key Vault, similar to the interfaces provided by Azure Storage or Amazon S3 for managing storages.
The skill level of the support staff is also questionable.
Implementing a degree of severity ranking is essential.
Endpoint Data Loss Prevention needs to be improved as it is not up to expectations.
 

Setup Cost

Azure Key Vault is seen as affordable with a pay-as-you-go model, though pricing opinions vary among users.
Microsoft Purview DLP in E5 licenses offers competitive pricing and flexible payment, valued for security features and added services.
I would classify it as low priced.
The pricing of Azure Key Vault is nominal, not that expensive.
We are planning to buy protection for Entra.
 

Valuable Features

Azure Key Vault offers secure, scalable key management with seamless Azure integration and comprehensive access control for enhanced security.
Microsoft Purview DLP enhances data security with auto-labeling, multi-cloud support, cross-platform protection, and strong compliance features.
It simplifies demonstrating in audits how I manage security in terms of rotation, password, and storage for encryption and decryption, whether in transit or at rest.
Since implementing Azure Key Vault, I have observed that instead of storing plain values, we can store them securely as and when required.
All secrets are in the Key Vault, and access is managed by the integrated management in ITT, which Azure provides to the services.
The feature I find most valuable that I'm currently using is the quickness of the emails that the Microsoft Purview Data Loss Prevention solution sends to us, where we get notifications that say a user has potentially breached our data guideline rules, and we get those alerts continuously, allowing us to enforce them manually.
Microsoft Purview Data Loss Prevention usually performs well, except for endpoint Data Loss Prevention, which may need improvements.

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.

Nice dashboard, good data loss prevention, and helps with compliance
The data loss prevention is great. It can prevent things like credit card information from being taken. The data protection is excellent. We can use the solution on Windows and iOS. We mostly use it with Office 365 and ingest data sources from Microsoft. The solution is natively integrated and compliant across Azure. It takes into account critical regulations from around the world. We need to comply with various regulations. For our business case, it's very important. If we can prevent information from going out, eventually, when a regulator is asking about our security measures, we can show what we've been doing. It helps us to reduce the likelihood of potential fines. We can educate users on how to handle sensitive data. By showing the records we keep and explaining the technologies implemented, we can provide awareness to our users. The solution offers good visibility into our environment. Our security team can use the product to monitor and track. Its dashboard allows us to show compliance in real-time. We've been able to reduce the time to action on insider threats. Security permissions are always being monitored. In general, it has saved us time and money when dealing with security. It's made us become more efficient. We've increased our compliance capabilities by 25%.
