Provide bot protection and has proficient documentation
During our discussion with the internal Microsoft team about assessing our environment, they confirmed that we have sufficient security measures, especially regarding edge protection. Internally, we believe we are now certified. In the future, we could consider adding layer four protection from the firewall. Front Door combines CDN and WAF protection, so further enhancing its features could benefit both the customer and us. We monitor the number of users attempting to access our IP or DNS servers. When designing the system, we initially needed to ensure our environment was protected with a WAF. However, WAF is currently too costly for us, so we created private links and connected them to Front Door. Overall, I rate the solution an eight out of ten.
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.
