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.

Effective threat prevention, reliable, and beneficial keyword blocking
The most valuable feature of SonicWall Email Security is the blocking of emails using keywords. If there are any particular keywords in the subject, that we want to block from receiving from a particular person we can do it. Additionally, the blocking of emails is easy. we can release that one and we can block some of the keywords also like that.

Cons

This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
