Protects sensitive data across devices and helps address client compliance needs proactively
The reporting in Microsoft Purview Data Loss Prevention is a little easier than most Microsoft portals. I understand the licensing cost, especially if you're a Business Premium or in the SMB world, and a lot of clients run with a Business Premium. That comes with data loss prevention in a manual process, whereas E5 gives automation. Microsoft has said, 'Okay, here's your Microsoft 365 E5 compliance add-on that can go on the Business Premium.' So Business Premium users can get the data loss prevention features of E5, which is fantastic. That was the big point that they were missing, and I'm glad that they actually have an add-on now that makes it possible. So truly, I don't think there's a downside. Maybe more reporting, but that's it.

Offers flexible licensing and easy setup, but has challenges with European compliance
It is difficult to meet the European security compliancy regulations using Proofpoint since it is very focused on the American market, differing significantly from European policies. Additionally, there is uncertainty about the future level of license pricing because American organizations sometimes change their product offerings. Barracuda's Active Directory checking feature is one area where Proofpoint could improve.

Pros

"The impact of Microsoft Purview Data Loss Prevention's classification and policy controls on our productivity within our organization is significant, as it's helped our security team."
"It has helped our clients to reduce the time to action on insider threats because it can be integrated."
"If we can prevent information from going out, eventually, when a regulator is asking about our security measures, we can show what we've been doing."
"Microsoft Purview Data Loss Prevention's ability to prevent unauthorized sharing of sensitive information is valuable."
"The solution's IDM (Indexed Document Matching), EDM (Exact Data Matching), and DCM (Described Content Matching) features have been most effective in identifying and mitigating potential data leaks."
"The product can block the uploads to cloud services."
"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."
"There's a good amount of documentation in case you run into any problems."
"Proofpoint offers flexibility in licensing, accommodating various levels from small businesses to governments."
"Proofpoint offers flexibility in licensing, accommodating various levels from small businesses to governments."
"We have too many features included in the solution. These include third-party malware detection as a primary feature and a secondary feature focused on dealing with various security threats."
 

Cons

"The support is poor."
"I would assess the stability and reliability of Microsoft Purview Data Loss Prevention as being flaky at times, where eDiscovery sometimes takes forever or doesn't bring the results we expect."
"The stability and reliability of Microsoft Purview Data Loss Prevention is great. Besides the weird timeframe where it takes a couple hours for a rule to sync and 24 hours to appear for someone, I don't really have an issue."
"Microsoft Purview Data Loss Prevention's licensing is expensive."
"The platform can be challenging to navigate and has the potential for improvement."
"A major improvement is required in the solution's incident handling and alerting."
"They do not provide language options beyond the ones already available, so our language option is missing."
"Some main features are limited in comparison to other solutions."
"It is difficult to meet the European security compliance regulations using Proofpoint since it is very focused on the American market, differing significantly from European policies."

Pricing and Cost Advice

"It is a part of our Microsoft licensing. We pay for a yearly renewal. Its price is reasonable for the size of the organization we are. It is fairly competitive, and you get what you pay for. We have an E5 license, and a part of understanding the E5 license is to see what all you get with it. If you really look at it from that standpoint, you get a lot of value. You have Defender and all its security features in there as well. Their licensing is fairly flexible. They have different programs. We've seen ones where you could pay for up to three to five years in advance. There is also a monthly pay-as-you-go type of deal, but we're doing a yearly renewal and fixing the budget."
"Microsoft Purview Data Loss Prevention is part of a bundle and is not sold as a standalone product."
"The cost works out to about $15 per user per month."
"Though I am not a specialist, the tool is quite expensive."
"I am satisfied with the tool's pricing."
"We are using the E3 license for Microsoft 365 with the E5 compliance license add-on."
"If one is very cheap and ten is very expensive, I rate the price as one out of ten."
"You get the solution in a bundle if you get the E5 suite."
