Sentiment score
7.1
Microsoft support is generally satisfactory, with users preferring higher-tier options for faster response and clearer communication.
I have a strong relationship with Microsoft since we are one of their best clients in Spain.
The skill level of the support staff is also questionable.
Azure Key Vault's technical support by Microsoft Azure is very good.
They are good at troubleshooting and configuring things.
I am very satisfied with the response from Microsoft dedicated architects if it happens that I have to call for their support.
I reached out to their support, and they helped me resolve the issue effectively.
 

Scalability Issues

Sentiment score

Azure Key Vault's scalability, seamless regional integration, and suitability for all business sizes receive high praise despite some dependency concerns.
Sentiment score
6.6
Azure Web Application Firewall offers flexible, highly-rated scalability, easily adapting to traffic changes and various workload needs across subscriptions.
Some Azure applications, like the web application firewall, require a certain level of SKU for hosting setup.
For our company, Azure Web Application Firewall works effectively for scalability.
 

Stability Issues

Sentiment score
8.2
Azure Key Vault is highly reliable and stable, with minimal issues, ideal for critical applications with high availability.
Sentiment score
7.1
Azure Web Application Firewall is highly stable, with minimal connectivity or performance issues and consistently earns high reliability ratings.
Very rarely do I see any latency issues.
 

Room For Improvement

Azure Key Vault needs better key rotation, mobile access, integration, interface, cost, vendor support, and disaster recovery features.
Azure Web Application Firewall needs better reporting, integration, cost plans, and process streamlining for enhanced management and support.
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.
Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.
The pricing needs improvement, and I think for beginners it will be a little bit complicated, so the ease of use could be enhanced.
 

Setup Cost

Azure Key Vault is seen as affordable with a pay-as-you-go model, though pricing opinions vary among users.
Azure Web Application Firewall offers scalable pricing, valued functionality, and favorable terms, appealing compared to AWS and GCP.
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.
It is even a lower cost compared to AWS and GCP.
Sometimes, when opting for a higher SKU, it's not the WAF itself that's costly but the additional requirements.
I would place Azure Web Application Firewall at an eight on a scale from one to 10, with one being cheap and 10 being expensive.
 

Valuable Features

Azure Key Vault offers secure, scalable key management with seamless Azure integration and comprehensive access control for enhanced security.
Azure Web Application Firewall offers robust security, seamless Azure integration, automatic rule management, and scalable, user-friendly deployment with minimal downtime.
All secrets are in the Key Vault, and access is managed by the integrated management in ITT, which Azure provides to the services.
It also helps me increase my security posture and assists with regulatory and compliance requirements.
Since implementing Azure Key Vault, I have observed that instead of storing plain values, we can store them securely as and when required.
With Microsoft, everything is within a single suite, making it easier to configure and plan.
It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure.
It integrates effectively with things such as Sentinel and Defender for Cloud, so mostly it's the analytics and now the AI capabilities that have been introduced with Co-pilot.

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.

Comprehensive suite simplifies configuration while frequent updates require management
Mainly, it comes with the complete suite of Microsoft services. I can use it in conjunction with the best options and other features that come with it. Configuration is much easier than using different platforms. For example, if I have hosted the application in AWS and am using the Application Firewall from Azure, there are certain additional steps to follow when configuring them. With Microsoft, everything is within a single suite, making it easier to configure and plan. Azure continually upgrades platforms and sends us messages to upgrade to the next version, simplifying the process. Later, it's much easier if I want to upgrade the software platform, scale it, or move it to a different application host as the whole suite comes together. The return on investment is good. If I am doing applications for clients, I can invoice them for better costs. Most applications that I run and use have a better return on investment.
