Featured Reviews

Paritosh Jani - PeerSpot reviewer
Associate VP (Managed Information Technology Services) at Dev Information Tech Pvt Ltd
Has delivered automated threat response and streamlined integration with advanced tools
The best features of Microsoft Defender for Business include it coming as an XDR solution which provides automated investigations, remediations, and endpoint detection and response. Moreover, it can be tightly integrated with vulnerability management or detecting vulnerabilities and pushing them to the SIEM solution. I utilize the advanced threat hunting feature of Microsoft Defender for Business and find it helpful; it's good and improving with every update. Microsoft Defender for Business integrates effectively with the Microsoft ecosystem as with Azure Sentinel, and it has a two-way natural integration. Apart from that, it also integrates with industry SIEM solutions such as Splunk.
Rohit Jaiswar - PeerSpot reviewer

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.
