SantoshDeshpande

Director Security Architecture at a financial services firm with 5,001-10,000 employees

A lot of functionality in Microsoft Purview Information Protection is not exposed in an API officially yet, which has made a lot of implementation work difficult because we have to do click ops instead of DevOps.

Kunle Oluwadiya

House security operator at Cypress Creek Renewables

Advanced threat hunting saves significant time in tracking and responding to incidents

Microsoft Defender XDR could be improved with a lower price. My main suggestion would essentially be what Copilot is providing, which is a single pane of glass, so I don't have to go to different windows. That's just a workflow consideration for me. It would be great to have all the information centralized into one particular data app. If I need to open up extra ones, I can, however, I would appreciate a future where everything I need is right there on one single pane of glass. Beyond that, there's really nothing else I see that I would want Microsoft to improve.

Achieve comprehensive data protection with reliable performance and room for enhanced discovery accuracy

Associate Director at LTI - Larsen & Toubro Infotech

The product is still in a growing phase. I could see that many use cases in their product are not capable enough in terms of detecting or protecting. Compared to other products, they are in the middle of bringing their solution up to the mark, so it is not a full-grown solution. They have to get more accurate results in terms of data discovery and classification. The second thing is their support; support from Microsoft takes a lot of time to get a response from their support team. The third thing is their OCR capability is not that great in terms of identifying the documents. We would love to see response times of less than 24 hours. Additionally, there is no way to check the policy's current status in terms of whether it got synced or not. You have to wait and test the use cases after 24 hours or after 48 hours, and once it starts working, then it appears the policy got implemented.
