Sentiment score
7.7
Microsoft Purview eDiscovery boosts ROI by improving data efficiency, compliance, risk management, and reducing legal and IT workloads.
Organizations typically do not rely solely on Microsoft products to avoid putting all eggs in one basket, which presents a challenge for maximizing ROI.

As a Microsoft partner, we receive significant discounts, making the solution affordable for us.
COO at Floating-Dot Technology LTD
We have seen a 100% return on investment.

The ease of accessing necessary information promptly is the biggest return on investment.

It's hard to quantify the ROI in a dollar amount, but we realize value by doing more tasks in less time than we did before.
Director, IT Infrastructure & Cloud Technology at a legal firm with 501-1,000 employees

Microsoft Purview eDiscovery is praised for responsive support, despite some mixed experiences with wait times and outcomes.
They are sometimes responsive, however, often issues cannot be reproduced on their end, making it challenging.

The support we receive from Microsoft is declining, and for example, after taking advanced support, we have not received satisfactory answers.
Microsoft Solutions Manager at Self-Employed
They are familiar with Microsoft products but are not direct Microsoft staff, which is an area needing improvement.

Microsoft Purview eDiscovery is scalable and efficient, seamlessly integrating with cloud infrastructures but lacks some search functions.
The integration is straightforward for those who understand it, though documentation needs improvement.
Cloud Security Engineer at a computer software company with 51-200 employees
It is scalable; I evaluated the product and decided to use Defender on over 700 of our company servers.
Security Specialist at Prudential Systems Japan
It scales with us seamlessly.
Director, IT Infrastructure & Cloud Technology at a legal firm with 501-1,000 employees
With the E3 licensing, I would rate the scalability of Microsoft Purview eDiscovery as a six because it lacks certain critical search functionalities.
Is admin at a energy/utilities company with 1,001-5,000 employees
 

Stability Issues

Sentiment score
6.7
Microsoft Defender Vulnerability Management is appreciated for stability and ease despite resource intensity and occasional compatibility issues.
Sentiment score
8.6
Microsoft Purview eDiscovery is generally stable, with minor slowdowns, but users seek more transparency on performance issues.
There are compatibility issues occasionally arising with false positives when other security tools are not whitelisted in Microsoft Defender.
information Security and IT Manager at Discover Dollar Technologies Pvt Ltd.
It is very resource-intensive, consuming a lot of memory and CPU.
Security Specialist at Prudential Systems Japan
If Microsoft experiences downtime, this solution goes down as it is a SaaS-based solution where we have no control.

Room For Improvement

Microsoft Defender Vulnerability Management needs simplified configuration, better integration, faster updates, and advanced features for improved security and efficiency.
Microsoft Purview eDiscovery needs faster, more efficient features, better integration, NLP for queries, and affordable pricing for users.
This scoring should be for specific industries as well. If I belong to the healthcare industry using Microsoft Defender Vulnerability Management, it should provide me with a risk score and show how I fare against the risk score of my industry.
DGM. Technical Security at a tech services company with 10,001+ employees
A vulnerability I patch within 15 minutes takes 24 additional hours for an update.

Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial.

Defining what constitutes a credit card because that is where I get the most false positives.

We find that many critical functions are available only to E5 license holders.
Is admin at a energy/utilities company with 1,001-5,000 employees
 

Setup Cost

Microsoft Defender Vulnerability Management offers competitive pricing in industry, though costs can be complex, especially for non-partners.
Microsoft Purview eDiscovery pricing is complex, with E5 costly yet beneficial, while E3 is cheaper but limited.
Overall, every organization wishes for cheaper options, but we look at the security side as well, so we are good for now.
Senior Cloud Security Consultant at MetLife
For non-partners, however, the cost could be seen as higher, between seven to ten.
COO at Floating-Dot Technology LTD
The pricing is reasonable, and it's included in the whole Microsoft E5 bundle, so it's all-inclusive.
Corporate Planner at MISC Berhad
With CSP or MCE-style agreements with Microsoft, the process is streamlined since we have reps from both Microsoft and CDW working together.
Director, IT Infrastructure & Cloud Technology at a legal firm with 501-1,000 employees
As an M3, I find the Purview pricing of 1250 per user worthwhile.
Senior System Engineer at a sports company with 5,001-10,000 employees
The pricing and licensing with Microsoft can be complex, and licensing is known to be a challenge because it changes frequently.

Microsoft Purview eDiscovery ensures efficient data retrieval with multi-platform integration, automation, compliance visibility, and adherence to global data privacy laws.
The main advantage of Microsoft Defender Vulnerability Management is that it can locate and prevent most threats even when the endpoints are not connected to the corporate network, as long as the internet is available.

The feature for customizing to region-specific and domain-specific requirements in healthcare is particularly beneficial.

OB
Microsoft Solutions Manager at Self-Employed
Ensures strong threat and vulnerability management with continuous risk assessment
The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.
Frank Radeck - PeerSpot reviewer
Director, IT Infrastructure & Cloud Technology at a legal firm with 501-1,000 employees
Tasks that took an entire day before we implemented the solution now take just 30 minutes.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive. It enables a streamlined, unified process for searching across these platforms. It is critical for Purview to be able to connect to iOS, Mac, and Android devices and data in other SaaS apps. From a support perspective, I can do things while I'm eating lunch or something else. It's more dynamic and responsive. I think everybody appreciates it. We're not tied to one device. Purview's multi-cloud capabilities are also essential for the same reasons. Keeping everything under one umbrella further increases the time savings. Purview accounts for critical regulations from around the world. This is crucial because we hold ourselves accountable to standards and need to align with them. Working at a law firm, we have clients who dictate to us what standards they expect. The visibility is excellent. As we move more things into the cloud, more opportunities exist to put everything under one umbrella.
