I would rate Microsoft Purview eDiscovery's customer service and technical support a ten.
 

Scalability Issues

Sentiment score
7.6
Azure Web Application Firewall offers flexible scaling options, dependent on subscription, with high ratings for managing large deployments.
Sentiment score
7.9
Microsoft Purview eDiscovery is scalable and efficient, seamlessly integrating with cloud infrastructures but lacks some search functions.
Some Azure applications, like the web application firewall, require a certain level of SKU for hosting setup.
It scales with us seamlessly.
With the E3 licensing, I would rate the scalability of Microsoft Purview eDiscovery as a six because it lacks certain critical search functionalities.
 

Stability Issues

Sentiment score
8.0
Azure Web Application Firewall is stable and reliable, with rare performance issues, mainly solved by system restart.
Sentiment score
8.6
Microsoft Purview eDiscovery is generally stable, with minor slowdowns, but users seek more transparency on performance issues.
Very rarely do I see any latency issues.
For us, it has been one hundred percent reliable.
Microsoft Purview eDiscovery is highly reliable.
 

Room For Improvement

Azure WAF needs improvements in management, deployment simplicity, affordability, IP support, and comprehensive documentation for better user experience.
Microsoft Purview eDiscovery needs faster, more efficient features, better integration, NLP for queries, and affordable pricing for users.
Upgrading the platform regularly is necessary for security, however, frequent updates every six months or year from Azure can be a maintenance overhead.
Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial.
Defining what constitutes a credit card because that is where I get the most false positives.
We find that many critical functions are available only to E5 license holders.
 

Setup Cost

Enterprise users find Azure Web Application Firewall cost-effective and straightforward compared to AWS and GCP, especially in Brazil.
Microsoft Purview eDiscovery pricing is complex, with E5 costly yet beneficial, while E3 is cheaper but limited.
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.
With CSP or MCE-style agreements with Microsoft, the process is streamlined since we have reps from both Microsoft and CDW working together.
As an M3, I find the Purview pricing of 1250 per user worthwhile.
The pricing and licensing with Microsoft can be complex, and licensing is known to be a challenge because it changes frequently.
 

Valuable Features

Azure Web Application Firewall offers scalable, easy-to-configure protection with flexible pricing, enhancing security against DDoS and unauthorized access.
Microsoft Purview eDiscovery ensures efficient data retrieval with multi-platform integration, automation, compliance visibility, and adherence to global data privacy laws.
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 most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive.
Purview can connect to iOS, Mac, Android, and SaaS apps, which is critical for capturing SMS and MMS text message data.
Purview's inclusion of global regulations is critical because we're heavily regulated by FERC, Sarbanes-Oxley, and the SEC.

Featured Reviews

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.
Frank Radeck - PeerSpot reviewer
Tasks that took an entire day before we implemented the solution now take just 30 minutes.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive. It enables a streamlined, unified process for searching across these platforms. It is critical for Purview to be able to connect to iOS, Mac, and Android devices and data in other SaaS apps. From a support perspective, I can do things while I'm eating lunch or something else. It's more dynamic and responsive. I think everybody appreciates it. We're not tied to one device. Purview's multi-cloud capabilities are also essential for the same reasons. Keeping everything under one umbrella further increases the time savings. Purview accounts for critical regulations from around the world. This is crucial because we hold ourselves accountable to standards and need to align with them. Working at a law firm, we have clients who dictate to us what standards they expect. The visibility is excellent. As we move more things into the cloud, more opportunities exist to put everything under one umbrella.
