Technical Solution Architect at liwa
Has enabled us to manage internal access securely but lacks accessible documentation for deeper integration
We haven't required any support, but overall, Microsoft support is good. Whenever we raise any concern, they are supporting us on time. Currently it is good. We are not a public-facing company; it is a retail company only, so that's why I don't think it is required. We don't have an e-commerce solution on Azure. For that, we are using a different stack for the e-commerce portal, so that is not in Azure. We are only using it for business applications, and I think L3 filtering in network security suffices for our problem currently. Regarding scalability for Azure Firewall, we don't need it here because the request to the application is internal. All are internal users. So there is not much request to get into the application, so scalability is not required for us in the current scenario.

Senior System Engineer at a sports company with 5,001-10,000 employees
Has made it significantly easier to handle rare litigation requests
The speed of it is valuable. I am able to search even 10,000 mailboxes for specific content. It helps search and accommodate the often limited information provided by users regarding what they need. It provides a solid starting point, and then we are able to refine the data from there. That has been very helpful because we do not always get enough information from our users to know what to look for. For example, a user is missing an email from x date but does not know anything else. In such a case, I give them a list of emails to look at so that they can tell me what they are missing. It is not a lack of the tool. It is more of a lack of the user providing info.
