Sentiment score

Microsoft Purview DLP offers cost savings, security enhancements, and reduced onboarding time, though ROI varies among users.
 

Customer Service

Sentiment score

Opinions on Microsoft Defender for Identity support vary, highlighting responsiveness, but issues include delays, contact challenges, and false positives.
Sentiment score
5.1
Microsoft Purview DLP support is inconsistent, with quick responses and clear resources but also delays and monopolistic concerns.
The quality of support is very good, but troubleshooting can take time due to complex setups and the need to provide many logs.
Generally, the support is more effective than other providers like Oracle.
Once we got to the Microsoft engineers, the experience was great.
 

Scalability Issues

Sentiment score
7.9
Microsoft Defender for Identity efficiently integrates and scales globally, supporting diverse organizational needs within Microsoft’s ecosystem effectively.
Sentiment score
7.6
Microsoft Purview Data Loss Prevention offers scalable, flexible cloud solutions, but needs improvements in user-friendliness and device-level scalability.
In a Microsoft-centric organization, especially with Azure infrastructure and Office 365, Microsoft Defender for Identity is scalable.
The policy working and detection technology need enhancements.
 

Stability Issues

Sentiment score
7.2
Microsoft Defender for Identity is highly reliable, with minimal incidents, seamless operation, and consistent ratings between seven and nine.
Sentiment score
7.8
Microsoft Purview Data Loss Prevention is highly stable, reliable, and responsive, though minor real-time issues and internal connection challenges exist.
Microsoft Defender for Identity is quite robust and built on Azure hyperscale infrastructure, with a 99% availability.
We do not see any issues with the stability of Microsoft Defender for Identity.
Having recently started using it, reliability is affirmed, but manual investigation is often performed to verify if alerts identified by auto-remediation are accurate.
Sometimes the solution is not stable when the internal connection is not reliable, so this aspect needs improvement.
 

Room For Improvement

Microsoft Defender for Identity users seek improved cloud integration, user-friendly features, better support, and streamlined processes for enhanced threat management.
Microsoft Purview DLP needs better integration, improved UI, enhanced AI features, cost-effective licensing, and better language support.
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.
Reducing false positives is something we've been working on with Microsoft.
One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform.
Implementing a degree of severity ranking is essential.
Endpoint Data Loss Prevention needs to be improved as it is not up to expectations.
 

Setup Cost

Microsoft Defender for Identity is cost-effective with E5 licenses despite complex pricing and competitive against other security solutions.
Microsoft Purview DLP in E5 licenses offers competitive pricing and flexible payment, valued for security features and added services.
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.
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
Ensuring a fair price according to market standards.
 

Valuable Features

Microsoft Defender for Identity integrates with Azure to offer comprehensive threat detection, identity protection, and advanced real-time security insights.
Microsoft Purview DLP enhances data security with auto-labeling, multi-cloud support, cross-platform protection, and strong compliance features.
We receive an advance report of risky users, allowing us to take preemptive action before an attack causes damage to organization details.
The most valuable feature is its hybrid artificial intelligence, which gathers forensic data to track and counteract security threats, much like the CSI series in effect.
The advanced threat protection is one of the strengths of Microsoft Defender for Identity, as it utilizes user and entity analytics and can detect indicative attacks.
The feature I find most valuable that I'm currently using is the quickness of the emails that the Microsoft Purview Data Loss Prevention solution sends to us, where we get notifications that say a user has potentially breached our data guideline rules, and we get those alerts continuously, allowing us to enforce them manually.
Microsoft Purview Data Loss Prevention usually performs well, except for endpoint Data Loss Prevention, which may need improvements.

Integration within the ecosystem enhances collaboration and automates functionalities
The integration into the Microsoft Defender ecosystem is the most valuable feature of Microsoft Defender for Identity. It fits very nicely with all the other Defender tools, allowing for excellent collaboration among them. It also fits seamlessly into Microsoft Sentinel SIEM. Furthermore, Microsoft security solutions can save time as they allow the automation of numerous functionalities, and the reporting inside the Microsoft ecosystem is commendable.

Nice dashboard, good data loss prevention, and helps with compliance
The data loss prevention is great. It can prevent things like credit card information from being taken. The data protection is excellent. We can use the solution on Windows and iOS. We mostly use it with Office 365 and ingest data sources from Microsoft. The solution is natively integrated and compliant across Azure. It takes into account critical regulations from around the world. We need to comply with various regulations. For our business case, it's very important. If we can prevent information from going out, eventually, when a regulator is asking about our security measures, we can show what we've been doing. It helps us to reduce the likelihood of potential fines. We can educate users on how to handle sensitive data. By showing the records we keep and explaining the technologies implemented, we can provide awareness to our users. The solution offers good visibility into our environment. Our security team can use the product to monitor and track. Its dashboard allows us to show compliance in real-time. We've been able to reduce the time to action on insider threats. Security permissions are always being monitored. In general, it has saved us time and money when dealing with security. It's made us become more efficient. We've increased our compliance capabilities by 25%.
