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.

Room For Improvement

Improving pricing, integration, stability, and support could enhance Microsoft Defender Threat Intelligence's market accessibility and effectiveness.
Microsoft Purview eDiscovery needs faster, more efficient features, better integration, NLP for queries, and affordable pricing for users.
Providing code customization would help keep pace with new vulnerabilities and threats.
Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial.
The reporting, sorting, and filtering capabilities that other products have aren't available natively in Purview.
We find that many critical functions are available only to E5 license holders.
 

Setup Cost

Microsoft Defender Threat Intelligence offers cost-effective bundling with E5 licenses, beneficial for enterprises but challenging for SMEs preferring E3.
Microsoft Purview eDiscovery pricing is complex, with E5 costly yet beneficial, while E3 is cheaper but limited.
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.
We acquired pricing through our reseller in NASDAQ, eliminating the need to search for prices ourselves.
 

Valuable Features

Microsoft Defender Threat Intelligence offers advanced detection, seamless integration, robust security, proactive monitoring, and effective zero-day vulnerability management.
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 is that it provides a certain level of customization, allowing us to set our spam confidence levels.
Purview's inclusion of global regulations is critical because we're heavily regulated by FERC, Sarbanes-Oxley, and the SEC.
Purview can connect to iOS, Mac, Android, and SaaS apps, which is critical for capturing SMS and MMS text message data.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive.

Nim Nadarajah - PeerSpot reviewer
A native Microsoft solution the provides great ROI and continuously improves its offering
We have Microsoft bias. We generally don't have any significant negative feedback or improvement points around Defender, EDR and CMDR platforms. It does a good job across the board. The price point is something they can improve slightly for those who don't have an M 365 E5. I believe it's a $2.80 cents add-on. In Canadian, that's expensive. If they can drop it to a dollar, for those who don't have M 365 E5, they're going to open up market share and increase affordability for an entire market segment in the medium business category. Other than that, we have no major negative feedback.
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.
