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.

Has an easy implementation phase to deal with for users
I primarily use the product in our daily security operations since it is implemented in all of our company's systems and is used in our environment. Normally, email security tools like FireEye or Trellix help to protect ourselves from spam, malware, and other email-oriented threats. The tool is used extensively in our company's environment. It is more like a collaboration email security that is used in our company. Whether my company plans to increase the number of users of the product or not is something that depends on the growth of the organization. I recommend the product to those who plan to use it. The product is stable and reliable, considering the results my company gets out of it. When it comes to Trellix or FireEye Endpoint Security (HX), the tools offer antivirus as well as the modern real-time security feature, which is used to automate the detection and protection of the endpoints against all the security threats that are currently there in the industry. I don't see any challenges with the integration part of the product, but since a different team manages it, I don't have visibility into it. In terms of the value offered by the product, the solution does help our company protect data and the complete infrastructure. I rate the tool a nine out of ten.
