Room For Improvement

Microsoft Defender for Identity needs improvements in alert accuracy, UI/UX, asset integration, automation, anomaly detection, and third-party integration.
Microsoft Purview DLP needs easier policy setup, improved third-party integration, real-time insights, and enhanced scalability features.
If Microsoft could develop a feature that indicates when impossible travel is caused by VPN connections, it would prevent unnecessary password resets and session disruptions, especially for VIP users in organizations.

Setup Cost

Microsoft Defender for Identity pricing aligns with E5 licenses, offering value in hybrid setups but can be costly at scale.
Microsoft Purview DLP is cost-effective with 365 E5, but add-ons and advanced features can be expensive and complex.
If they can reduce the costs, organizations will be happy, and it will compensate for using the Azure environment, which is more expensive on the infrastructure as a service side.
CyberSecurity Engineer | Information Security Management at Self Employed
Ensuring a fair price according to market standards.
Owner at Alopex ONE UG
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
Cloud Security & Governance at a financial services firm with 10,001+ employees
In terms of pricing, I would say it's unlimited value because it's bundled in our A5 and E5 licensing situation.
Director, IT Infrastructure at a university with 1,001-5,000 employees
The pricing for Microsoft Purview Data Loss Prevention is generally set; E5 is required, but it comes with all other products, so I would say it is fine.
Security Engineer at baseVISION
Advanced DLP and insider risk features became expensive when we scaled at the enterprise level.

Featured Reviews

Peter Arabomen - PeerSpot reviewer
Security Engineer at Fidelity Bank Plc
Has supported hybrid identity management while integrating well with cloud directory services
The only challenge I have with Microsoft Defender for Identity is the latency. I may not put that entirely on Microsoft, because latency could be network related. At times when trying to authenticate, the prompt is delayed. We tried implementing passwordless authentication, especially for on-premises workloads, but we haven't been able to achieve that. Passwordless authentication is part of the identity functionalities, particularly when it comes to enforcing passwordless for on-premises workloads. In terms of improvements, you can't create OUs on Azure AD. Regarding giving users privileges on what they can do across different OUs, I haven't seen that feature on Microsoft Defender for Identity. Microsoft Defender for Identity needs to be able to plug into third-party applications that are not Microsoft. For instance, with a human resource application used to manage users and leave requests, when staff leaves the organization, they are first exited from that application before AD. Integration between Azure AD and third-party applications would allow automatic syncing when removing staff. The initial setup of Microsoft Defender for Identity is not hard. However, setup is one thing, and getting value from the application end-to-end is another. It can be set up and running from the first day but not functioning optimally. Initially, when we did the setup, it wasn't optimal. Over time, with continuous improvement, which we're still doing, we've gotten to a comfortable level, but there's still room for improvement.

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.
