Ensures data security with advanced intrusion prevention and 24/7 monitoring
I rate the initial setup as ten out of ten. It is straightforward to set up a CloudGen file, taking a couple of hours. Once we have the configuration agreed with the customer, the setup and onboarding are completed within a few hours. We receive the box from Barracuda or from our stores, pre-stage it into our network for initial configuration and Soak testing to ensure functionality. The customer can install it at their location, or we do it on their behalf. We run the firewall in simulation mode to observe traffic and ensure service transition is effective. After confirming functionality with the customer, we transition to a live service.

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.
