Setup Cost

Microsoft Purview Data Loss Prevention in E5 licenses offers competitive pricing and value with bundled security features and flexible options.

Trellix DLP pricing is user-dependent, device-based, and considered reasonable, but can be high due to currency conversion.

In terms of pricing, I would say it's unlimited value because it's bundled in our A5 and E5 licensing situation.

It used to be in the middle, tending towards the high end, especially in South Africa, where we need to convert from dollars to rands, making things very expensive quickly.

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.

Distributors highly benefit from advanced data monitoring and seamless integration features

The Machine Learning capability could be improved, particularly in data discovery. When given sensitive data expressions, the system retrieves files that are not always related. The system should adhere strictly to the given expression rather than just focusing on keywords within the expression. In endpoint features, while the detection rate is good, there could be improvements in remediation and rollback solutions during attacks. Other solutions now include such options since providing 100% security is impossible. The flexibility varies across environments. Enterprise customers find the product performs well without affecting their data, with scans running as scheduled. However, SMB customers experience some performance issues during scanning. Since EDR is integrated, users must access the EDR console to check endpoint detections. It would be beneficial if this functionality were incorporated within the EPO console, as the current threat graphs link doesn't display endpoint threat graphs.
