If one is looking for a bulletproof solution, then Proofpoint Enterprise DLP is the answer. I feel confident enough in the solution's effectiveness in detecting and preventing threats through the analysis of email content and user behavior that I would choose to keep it, even if we switch to Microsoft E5 licenses, and we have had no incidents to speak of related to malicious attachments or malware infections. I don't really see the unified platform aspect of Proofpoint Enterprise DLP as unified. It's an additional layer, and we are okay with that additional layer of security.

I assess the effectiveness of Proofpoint Enterprise DLP in detecting and preventing data loss through user behavior and content analysis, and I would say effectiveness is displayed in that they had a solution which they could never move to a blocking scenario; however, with Proofpoint Enterprise DLP they were able to do it. If the rule sets and data sets are not right, the customer would never have even gone to the blocking mode. It is a continuous process with false positives and negatives, and the solution helps a lot in figuring out what will not work, but there is a gap in pinning out exact problems with datasets. We have used the auto-learned classifiers within Proofpoint Enterprise DLP, with around 60 to 70% accuracy, as we knew where the data is located, and while the crawlers helped, we faced some problems when different languages, such as Arabic, were in use, which was a challenge for us. My advice to others looking into using Proofpoint Enterprise DLP is to understand the source they need to protect, then pick the solution that suits their environment and use case, understanding the product before buying. I would rate this product an 8 out of 10.

My advice for organizations considering Proofpoint Enterprise DLP is to start with a clear data protection strategy and not begin with technology. Start by determining what data you are trying to protect, which regulatory obligations apply, and identifying your highest risk outbound channels. Proofpoint Enterprise DLP works best when aligned with a defined data classification and governance framework. A phased rollout is recommended, beginning in monitoring mode to collect baseline data, tune policies, validate false positives, and gradually enforce blocking or encryption to prevent user disruption and SOC overload. Finally, focus on high-risk use cases first, protecting payroll or HR data, financial records, and then confidential client information. I would rate this solution an 8 out of 10.
Proofpoint Enterprise DLP works in the synchronization of Proofpoint Production on Demand and Proofpoint IMD, which is the Internal Mail Defense solution. When any user account gets compromised or an attacker gains access to an internal user account, they will pretend to be an insider threat and start moving confidential information outside of the organization. In that case, Proofpoint Enterprise DLP plays a very important role in easily identifying all these activities from the backend, using machine learning and advanced analytics. UEBA, which is User and Entity Behavior Analytics, performs checks on the user's day-to-day activity on the backend side. It examines what is the daily routine timing, what the user is trying to do every day, and how it is different from some specific day. Based on all those things, it correlates, it identifies, and based on machine learning, it becomes very easy for the DLP solution to take decisions. It's a very good solution in terms of preventing or protecting from DLP incidents. I think organizations should go ahead with Proofpoint Enterprise DLP. Every day they are coming with more advanced features, more scalability, and more upgraded versions. I would rate this solution as an eight out of ten.
