Technical Solution Architect at liwa
Has enabled us to manage internal access securely but lacks accessible documentation for deeper integration
We haven't required any support, but overall, Microsoft support is good. Whenever we raise any concern, they are supporting us on time. Currently it is good. We are not a public-facing company; it is a retail company only, so that's why I don't think it is required. We don't have an e-commerce solution on Azure. For that, we are using a different stack for the e-commerce portal, so that is not in Azure. We are only using it for business applications, and I think L3 filtering in network security suffices for our problem currently. Regarding scalability for Azure Firewall, we don't need it here because the request to the application is internal. All are internal users. So there is not much request to get into the application, so scalability is not required for us in the current scenario.

Integrated controls have reduced insider risk and now protect sensitive data across our workforce
One standout feature about Microsoft Purview Data Loss Prevention is the tight integration with Insider Risk Management and Defender XDR, as it gives much better context during investigations instead of treating DLP as an isolated alerting tool. We also use endpoint DLP heavily to control USB, copy, print, clipboard, and browser upload activity, which has been very effective for remote workforce security. The best features Microsoft Purview Data Loss Prevention offers include real-time policy enforcement, endpoint DLP, and deep integration with Microsoft 365 plus Defender XDR. We also heavily rely on sensitive information type detection, adaptive policy tips, and insider risk integration to investigate suspicious user behavior with proper context. Another standout feature is the ability to control USB copy, browser uploads, print clipboards, and cloud sharing actions directly from endpoint policies. The integration with Microsoft Defender 365 and Defender XDR helps our team in day-to-day operations because DLP alerts are automatically correlated with endpoint identity, email, and user activity telemetry, which helps the SOC investigate incidents much faster from a single workflow. The sensitive information type detection makes a difference compared to other tools we have used because it is more effective than many legacy DLP tools. It understands context, exact data patterns, document labeling, and Microsoft 365 native content, reducing false positives while improving detection accuracy. Another strong feature of Microsoft Purview Data Loss Prevention is auto-labeling and policy inheritance with Microsoft's Information Protection, which helps maintain protection even after files are shared or moved across workloads. We also value the user coaching or policy tip capability because it educates users in real time instead of only blocking actions, which reduces repeated DLP violations significantly.
