Microsoft Purview eDiscovery boosts ROI by improving data efficiency, compliance, risk management, and reducing legal and IT workloads.
Without detection and protection measures, organizations would face substantial payments and reputational damage, including the necessity to inform customers about data breaches, potentially leading to loss of business.

The level-one support seems disconnected from subject matter experts.
I rate Microsoft support 10 out of 10.
Due to our size, we don't have access to direct technical support, but the knowledge base, Microsoft Learn, and the articles available are really good.
I would rate Microsoft Purview eDiscovery's customer service and technical support a ten.
 

Scalability Issues

7.7
Microsoft Defender for Endpoint is scalable and integrates well with Microsoft’s ecosystem, despite needing improvements for handling massive data.
Sentiment score
7.9
Microsoft Purview eDiscovery is scalable and efficient, seamlessly integrating with cloud infrastructures but lacks some search functions.
We managed to scale it out in a short amount of time, with two months of planning and three months of implementation on 10,000 computers.
Microsoft Defender for Endpoint is scalable enough to handle various devices across environments, whether they are laptops, Android devices, or operating in hybrid environments.
Compatibility is its main feature.
It scales with us seamlessly.
With the E3 licensing, I would rate the scalability of Microsoft Purview eDiscovery as a six because it lacks certain critical search functionalities.

Microsoft Defender for Endpoint is praised for its reliability and stability, with minor concerns about resource intensity and performance.

Room For Improvement

Microsoft Defender for Endpoint faces interface complexity, slow detection, high CPU usage, integration issues, and seeks improvements in multiple areas.
Microsoft Purview eDiscovery needs faster, more efficient features, better integration, NLP for queries, and affordable pricing for users.
Repeated interactions are necessary due to Level One's lack of tools and knowledge, hindering efficient problem-solving and negatively impacting our experience with Microsoft support.
In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment.
We use Microsoft partners to help govern the platform, and as part of an alliance, we want to gather data from each tenant and combine them for a complete view.
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.
 

Setup Cost

Microsoft Defender for Endpoint offers flexible pricing, making it competitive and cost-effective compared to standalone security products.
Microsoft Purview eDiscovery pricing is complex, with E5 costly yet beneficial, while E3 is cheaper but limited.
Given our extensive Microsoft licensing, transitioning to Defender for Endpoint did not affect licensing costs.
It costs $15 per VM for the P2 plan, which is seen as affordable for customers.
The pricing, setup, and licensing were very easy and simple.
With CSP or MCE-style agreements with Microsoft, the process is streamlined since we have reps from both Microsoft and CDW working together.
As an M3, I find the Purview pricing of 1250 per user worthwhile.
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.

One of the best features of Microsoft Defender for Endpoint is its database for identifying zero-day attacks or malware attacks.

Featured Reviews

NaySan @ Suraj Verma - PeerSpot reviewer
Has effectively blocked sophisticated attacks and malicious activities while providing excellent support
Microsoft Defender for Endpoint is very good, but one suggestion is that in some products, we may need to configure security-related settings, whereas Microsoft Defender for Endpoint works completely differently, providing automatic recommendations and actions that we may need to perform ourselves. Regarding the pricing of Microsoft Defender for Endpoint, during the last three years, we set up the product and sold it, but we faced difficulties because Microsoft pricing is always the same. For example, whether I purchase Microsoft Defender for Endpoint for one year or for the next three years, the pricing remains constant with no discounts available. In contrast, competing products offer reduced pricing for long-term commitments, which makes it difficult for us in that environment. Microsoft should consider this option to remain competitive, but otherwise, everything else is fine.
Frank Radeck - PeerSpot reviewer
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.
