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.
Gabor Nyerd - PeerSpot reviewer
Includes four services and four products, which can help organizations a lot
We found that sometimes integrations work, but testing them can take some time. Sometimes, configurations take much longer than expected. We have a configuration in place that needs to be synchronized with another server. However, the servers are four hours apart, so this can cause delays. In general, I believe that the time it takes to configure and test a service should be shorter. Sometimes, it can take a couple of hours to test a single configuration setting. Other times, it is only ten or fifteen minutes, which is normal. However, sometimes, even immediate actions can be triggered by configuration changes, and some settings can take up to eight hours to complete. I believe that this time can be improved. Microsoft is making a lot of improvements to its services in a short period of time. This is a good thing, as it means that the services are constantly being updated and improved. However, it can be challenging for customers to keep up with the changes. For example, a customer may read about an update, understand it, and share it with their colleagues and boss. However, it may take days or weeks to test the update and get the necessary approvals. This can be especially challenging for large customers with many users or machines. In some cases, Microsoft may change a service before the customer has had a chance to implement the previous update. This can be frustrating for customers, as it means that they have to constantly learn new things and adjust their workflows. On the one hand, it is important for Microsoft to keep updating and improving its services. This helps to ensure that the services are meeting the customers' needs and that they are staying ahead of the competition. Microsoft should also be mindful of the challenges that these changes can create for customers. One way to address this challenge is to provide customers with more time to implement changes. Microsoft could also provide more information about upcoming changes so that customers can plan ahead. Ultimately, Microsoft needs to strike a balance between keeping its services up-to-date and providing customers with a smooth transition to new features.
