Featured Reviews

Rizki Arya Indracahya - PeerSpot reviewer
Efficient integration and log monitoring enhances security operations
The central management needs improvement. The ease of use for updating and managing through the web console is difficult and lacks features. Integration with Mobile Device Management ( /categories/mobile-device-management-mdm ) is not good, and controlling client update times can become problematic. If there is a network issue during an update, it can create junk files on the system, filling up disk space.
Syed Abid  - PeerSpot reviewer
Advanced threat protection secures diverse workloads with cost-effective deployment
If I need logs and don't have local storage bundled with Defender, I need to add workspace and log analytics, which is costly for storing logs of 2 GB, 5 GB, 10 GB. A default storage of 5 GB for logs should be included with Defender. There are limitations in whitelisting folders and files, and the whitelisting feature for Defender threat protection was deprecated. A straightforward feature for this should be added.
