Customer Service

Sentiment score
6.8
Azure Key Vault support is praised for responsiveness and reliability, with minor issues in reaching experts and clarity.
Sentiment score
7.1
Azure Web Application Firewall support varies by service level, with mixed reviews on responsiveness, effectiveness, and necessity of premium plans.
The skill level of the support staff is also questionable.
Azure Key Vault's technical support by Microsoft Azure is very good.
I have a strong relationship with Microsoft since we are one of their best clients in Spain.
I hardly use Microsoft's paid subscription or maintenance services, however, whenever I send them a note, they have been responsive.
I would rate the technical support that Azure provides from Microsoft a seven.
I reached out to their support, and they helped me resolve the issue effectively.
 

Scalability Issues

Sentiment score
7.5
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, adapting regionally to traffic, benefiting users with varying and demanding workloads.
Beyond a certain SKU, I can install and use these services.
For our company, Azure Web Application Firewall works effectively for scalability.
 

Stability Issues

Sentiment score
8.4
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 stable and reliable, with infrequent latency issues typically resolved by restarting the system.
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 improved management, integration, performance, support, and more affordable pricing for enhanced user experience.
The skill level of the support staff is also questionable.
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.
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.
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 competitive and cost-effective pricing, especially favored for enterprise agreements and its simplicity.
I would classify it as low priced.
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 strong security, customizable rules, seamless Azure integration, efficient setup, flexible pricing, and effective monitoring.
It also helps me increase my security posture and assists with regulatory and compliance requirements.
All secrets are in the Key Vault, and access is managed by the integrated management in ITT, which Azure provides to the services.
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 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.
It is almost impossible to access these assets from outside, requiring a very skilled attacker to obtain asset tokens of a customer using Azure.

Featured Reviews

RituparnaBhattacharya - PeerSpot reviewer
Secret storage and certificate management have been streamlined
I am not on the developer's end. I am primarily the main infrastructure person. I'm not sure what needs improvement. Sometimes, we face issues that the support team is not aware of, necessitating investigation from their end. For example, 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. Improvements can be made in this area, however, it's understandable that not everything can be perfect.
Mano Senaratne - PeerSpot reviewer
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.
