Featured Reviews

Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Comprehensive identity management enhances security and access controls with advanced integration
The monitoring from Microsoft Entra ID Protection provides great visibility at a granular level. It provides all the details, including IP address, username, and permission or error logs. This information is available in both the audit log and regular log. The alert functionality supports general day-to-day monitoring and any violation or trigger for errors. Microsoft Entra ID Protection's features are suitable for all sizes of companies. It's a must-have product because traditionally Active Directory was used for identity and authentication on computers. Now, with hybrid capabilities, every company of any size needs these features and tools. I rate Microsoft Entra ID Protection ten out of ten.
