Room For Improvement

Microsoft Defender for Business needs better reporting, integration, simplified interface, and enhanced features to address various limitations and concerns.

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.
Corrado Vigano - PeerSpot reviewer
Solution integrates well with existing systems while being easy to use
The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use. Furthermore, Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company. The solution is easy to reuse and not difficult to find expertise for in the market because it is widespread. It is gaining attention even from partners and from the market on the offering side. This serves as a good starting point for customers who can develop internal competence on the solution. Additionally, the presence of reliable partners who know the solution and can provide internal knowledge is the best aspect for them.
