Senior Cybersecurity Specialist at a retailer with 10,001+ employees
Has provided reliable threat detection and simplified policy management
I do not have experience with Microsoft Purview products, but I know some Proofpoint products. I apologize, I do not have experience with the Purview one, but I do know the Proofpoint products. I'm not sure about the features of the Purview one. Compared to other products, Proofpoint's real-time threat intelligence makes it less noisy. They collect and share threat information effectively, which benefits all customers. I have seen a lot of improvements in Proofpoint's reporting and analytics compared to earlier days. As a leader in the market, I find the pricing for Proofpoint Email Protection is a little high. Their licensing models vary, and even the premium model adequately supports awareness campaigning, so I find it acceptable. Normally, they sell their products through resellers, not directly through AWS Marketplace. For us, we are clients of Proofpoint. I rate Proofpoint Email Protection a nine out of ten.

World-class support and highly effective for application control and elevation
Their product is solid. I have a hard time complaining much about it because when we do find little things, they are usually interface-related or related to things that would be nice to have. Their idea portal, unlike so many other vendors we deal with, shows movement. At least four to eight features of ThreatLocker exist because I made a request in the last five years, and it became a feature of the actual product. When it comes to improvements, we moved the product as customers, and we got to move the product by making suggestions. They seem to be very reactive to it, so there is not a whole lot that they actively need to change right now. It is one of those situations where when we run into something that would be nice to have, it happens. They make it work.
