Dinesh Jaisankar - PeerSpot reviewer
Cloud Architect at Vision Bank
Security architecture shields infrastructure but dashboard needs enhancement
The Azure DDoS Protection plan is essential for environments like ours that are highly exposed to potential attacks, especially since DDoS attacks have become common. The security architecture with Azure DDoS Protection is critical for safeguarding our financial organization's infrastructure. Although implementing it is pricier, it is worth using since our applications are entirely in Azure.
reviewer2595618 - PeerSpot reviewer
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.
