Featured Reviews

Karthik Ekambaram - PeerSpot reviewer
Have consistently built secure internal environments while implementing compliance tools for diverse customer needs
The customizable alerts system needs improvement. The detection rules are not extensive enough. There should be more possibilities for creating alerts based on additional criteria. While rules can be customized, the available criteria for creating detection rules should be expanded. Microsoft's pricing is very expensive. The Business Premium offering should be extended to enterprise customers, as it's currently limited to 300 users. There should be a tier below E5 that includes Microsoft Purview and other features. Currently, E5 licensing costs approximately 6,000 INR per user per month including taxes. Competitive solutions offer similar functionality at about 50% of Microsoft's cost. Email DLP is included in Business Premium or P1 licenses, while P2 licenses cover endpoint DLP and additional channels. Microsoft should introduce an intermediate tier below E5 that covers all P1 licenses, as customers often need coverage across the entire M365 suite.
