Executive Summary

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
4.4
Azure WAF cuts costs, eliminates third-party needs, improves ROI, meets security requirements, and offers reliable, favorable protection.
Sentiment score
6.7
Microsoft Purview DLP offers cost savings, security enhancements, and reduced onboarding time, though ROI varies among users.
AI-based recommendations save on time and money.
Recently, they have been under serious attack with major exploits, such as Log4j, affecting Fortinet and Palo Alto, and even Cisco and VMware.
 

Customer Service

Sentiment score
7.1
Azure Web Application Firewall support varies; premium plans offer better service, while others find self-reliance sufficient.
Sentiment score
5.1
Microsoft Purview DLP support is inconsistent, with quick responses and clear resources but also delays and monopolistic concerns.
I hardly use Microsoft's paid subscription or maintenance services, however, whenever I send them a note, they have been responsive.
I reached out to their support, and they helped me resolve the issue effectively.
I am very satisfied with the response from Microsoft dedicated architects if it happens that I have to call for their support.
Once we got to the Microsoft engineers, the experience was great.
 

Scalability Issues

Sentiment score
6.6
Azure Web Application Firewall offers flexible scaling options, dependent on subscription, with high ratings for managing large deployments.
Sentiment score
7.6
Microsoft Purview Data Loss Prevention offers scalable, flexible cloud solutions, but needs improvements in user-friendliness and device-level scalability.
Beyond a certain SKU, I can install and use these services.
The policy working and detection technology need enhancements.
 

Stability Issues

Sentiment score
7.1
Azure Web Application Firewall is stable and reliable, with rare performance issues, mainly solved by system restart.
Sentiment score
7.8
Microsoft Purview Data Loss Prevention is highly stable, reliable, and responsive, though minor real-time issues and internal connection challenges exist.
Very rarely do I see any latency issues.
Sometimes the solution is not stable when the internal connection is not reliable, so this aspect needs improvement.
 

Room For Improvement

Azure WAF needs improvements in management, deployment simplicity, affordability, IP support, and comprehensive documentation for better user experience.
Microsoft Purview DLP needs better integration, improved UI, enhanced AI features, cost-effective licensing, and better language support.
Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.
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

Enterprise users find Azure Web Application Firewall cost-effective and straightforward compared to AWS and GCP, especially in Brazil.
Microsoft Purview DLP in E5 licenses offers competitive pricing and flexible payment, valued for security features and added services.
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.
 

Valuable Features

Azure Web Application Firewall offers scalable, easy-to-configure protection with flexible pricing, enhancing security against DDoS and unauthorized access.
Microsoft Purview DLP enhances data security with auto-labeling, multi-cloud support, cross-platform protection, and strong compliance features.
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.
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.

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.
Roby Skariah - PeerSpot reviewer
Automation has given us consistent analytics and improved quality of insights into user activity
One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site. If you want to retain the user's data until the case is resolved, you can use the legal hold feature. Also, it's important that Purview can connect to iOS, Mac, and Android devices. With smartphone involvement, so many applications can now be accessed through them and it is important to apply Purview across operating systems and platforms. Purview's natively integrated compliance across Azure Dynamics and Office 365 is also significant because within Microsoft 365 there are multiple applications. Irrespective of whether it's Dynamics or Azure, it's very important that it has native support. The data connectivity should be efficient enough to support and secure their own platform's data. In addition, with varying regulations in different industries and matters, Purview lets you create rules and conditions based on industry standards around the world. That is important. Our company is in pharmaceuticals and the rules and conditions are different from other industries. It is important to be able to keep track of all these regulations and have a tool that is flexible enough to create the regulatory rules and conditions we need. And when it comes to data loss protection, Purview has features that can recognize patterns and detect any sort of data loss, where the data is being transferred from its platform to a different one. The default settings that come with it are pretty nice for identifying data transfer or data loss across the platform. It also comes with a lot of training materials, with use cases and examples, to help educate users and make them familiar with the tool.
