Auto scanning and enhanced security but re-adding protections need improvement
At that time, we observed certain issues with the product. The functionalities could be improved, such as the isolation feature. If we remove our protection, we cannot easily add it back. If, in our organization, we need to remove a specific system for a particular time, we cannot add it back for security after doing so. This is one thing we have experienced. Scalability is also lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong.
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.
