Room For Improvement

Microsoft Defender Threat Intelligence needs pricing, integration, support, AI, automation, and customization improvements for better affordability and usability.
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.
From the telemetry data standpoint, I would prefer Defender data to be more open in future updates.
The reporting, sorting, and filtering capabilities that other products have aren't available natively in Purview.
Defining what constitutes a credit card because that is where I get the most false positives.
Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial.
 

Setup Cost

Microsoft Defender Threat Intelligence is cost-effective in E5 bundles but can be complex and costly standalone for SMEs.

Featured Reviews

TapabrataSamanta - PeerSpot reviewer
A cost-effective solution for monitoring and security but lacks supports for non-Microsoft products
There are weaknesses, and Microsoft is working on addressing them. Over the past three to four years, the ATP and other components have improved significantly, and the integration has also advanced. We are using third-party services. While we have Microsoft Threat Intelligence, which leverages Microsoft's facilities, we also utilize additional third-party threat intelligence. As of today, we don't completely rely on Microsoft for certain regions. This is an area where Microsoft needs to improve. Consequently, we use Anomali, a third-party threat intelligence provider. We integrate our product's intelligence with Anomali, from which we obtain threat insights. Microsoft products offer significant advantages, especially in the realm of threat intelligence. It works very well with Microsoft products. However, you might need additional services if you have non-Microsoft products in your environment. For instance, if you use Apple or Linux, Microsoft's solutions alone might not be sufficient. If they can work more effectively, especially with zero-day attack speed and other sophisticated threats, it will help us provide our customers with timely newsletters about new attacks.
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.
