Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Automated data discovery has streamlined management while configuration remains complex
Compared to Big-ID, Microsoft Purview Data Governance looks complicated to me. I do not feel it has a good user-level UI. The interface feels a little complicated compared to Big-ID. I did not appreciate the configuration part. It felt complex, whereas when I went for a Big-ID demo, the interface looked better and was easier to understand for any user.

Quotes from Members

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

Pros

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It seems to be better at protecting from cyberattacks."
"Overall, Purview is a fantastic tool for staying on top of compliance, knowing where your data is and what data you hold."
"The availability of pre-designed policies tailored to specific geolocations and customer requirements is a valuable feature."
"Their data labeling or data classification is particularly valuable because we want to categorize all of our data into confidential, public, or internal."
"It's certainly easy to work with all Microsoft data sources like SQL Server, Synapse, and data lakes, but it also has great functionality working with Oracle. And of particular interest to us is the ability to pull data from Excel, CVS files, and other types of flat files."
"Overall, I would laud its ease of use, intuitive interface, and easy navigation."
"The most valuable aspect of Purview is its PowerShell connectivity, enabling automation."
"The most valuable feature is the tracking activity and device onboarding."
"It is pretty early, but the decision to go with this investment was largely driven by the simplification of our information security technology management stack. That is the primary objective. Once you simplify and you have a connected structure, it allows for faster adoption there. It also gives us additional capabilities as we go on using the technology that we are familiar with, and we do not have to depend on outside parties to come in and tell us how to do certain things."
 

Cons

"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
"Further integration across different Microsoft products would be an improvement."
"Purview's data connector platform for non-Microsoft data sources is good, but there is some functionality that hasn't been developed yet. There are some servers that it can't connect to yet, because they're still in a trial process."
"Blueprints and landing zones like we have in Azure would be great to see in Purview. The solution could offer a baseline or blueprint of recommended settings for compliance regulations such as GDPR and ISO, which could be applied with a simple switch in the options."
"There are negatives to the compliance aspect of Purview in that you get a lot of false positives with some of the native scanning and rules in the platform. A lot of them need tweaking to get a more realistic handle on what data there is."
"Another area for improvement is in managing the business glossary terms. If they could provide the same type of method that we use to configure the scan rule sets, that would be helpful. Currently, there is no option like this, so we have to do it manually. Automatic detection would be great."
"As Microsoft Purview got a little more mature, the deployments got a little more complex, as we were kind of seeing that there are a lot of ways, like there were a hundred ways to do one thing or less."
"Frequent daily updates from Microsoft can cause interface elements like buttons to appear and disappear, making navigation unpredictable."
"Auto-tagging should be available at lower levels of licensing. Right now, a high level of licensing is needed for auto-tagging, and this feature should be made available at a lower license level."
"Two features are unsupported—custom insights and the DLP component—that would be beneficial to me as a consultant and for the customer in terms of security and monitoring. Regarding security, DLP would provide a more granular level of data masking. Custom insights would offer more detailed monitoring and alerts that can notify customers of failures or anything requiring urgent action."
 

Pricing and Cost Advice

Information not available
"Purview is included in our Microsoft E5 licensing."
"The pricing is decent. It is neither too low nor too high. Given its capabilities, the pricing is justified."
"Some people find the tier licensing system complicated, but it offers a lot of value for money if we use the features."
"The price is reasonable considering its value."
"Microsoft Purview is the best option I have encountered when it comes to price. Maybe some of my information is outdated, but Microsoft offered it so that you could use it almost without paying."
"The solution is extremely affordable for the K-12 space."
"Licensing is frustrating due to multiple modules and licenses. The feature might be available in the console, but it won't work without the proper license, creating confusion."
"The price is reasonable because most of our clients already have an E3 license, which makes implementation easy."
