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.

Offers comprehensive security, easy integration, and good support
It integrated easily. About 99% of the time, we do not face any challenges in integrating any product of Trend Micro with the existing network. It is usually compatible with all kinds of networks. They have recently added AI to all Trend Micro products. It makes life a little bit easier by catching viruses, providing solutions, and helping out whenever you are stuck somewhere. It is one of the very good features they have right now. For example, one of our clients experienced a network attack and became confused about resolving the issues. The AI was helpful by suggesting initial steps to solve the problem.

"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Before installing, consider potential challenges with system performance, especially when integrating multiple tools, which could slow down performance."
"We have had very good results from the use of FireEye Email Security. We are very comfortable with this technology, but I don't know if it's necessary to move into the cloud, we will check other technologies and study them. Additionally, the solution has good integration."
"The auto-remediation feature is valuable."
"FireEye Email Security is easy to use."
"We can control this solution from the cloud and are able to access it from wherever we are."
"FireEye Email Security helps us prevent spam and phishing emails and all other business-compromised email attacks."
"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."
"FireEye is good for malware depicting and security."

"Trend Micro Email Security is a robust solution with quick performance. It works autonomously without the need for an administrator."
"The most valuable features include email filtering to block spam and phishing attempts, the use of DMARC for email authentication, and robust malware scanning."
 

Cons

"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"The UI needs to be more user-friendly."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"The GUI is sometimes slow to fetch the device report and could be improved."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"If they want to be the primary or best solution, they need to have better email management features."
"The custom tailoring is limited."
"In general, our company should make the tool more robust to protect our systems."
"There is a need for improved integration with totally different products, such as a rapid server."

"There is room for improvement in threat detection, especially for advanced attacks and business email compromise."
"It is a bit expensive than the market price."
"They need to adjust the spam filtering and make it stronger."
"I rate Trend Micro support four out of 10. The support in our region isn't very good. They do not respond quickly when we open up a case."
"There is a lot of room for improvement towards the phishing kind of email filtering, with the different hijacking attacks, and with the kind of password attacks which these phisher attackers do."
"The product must provide better customization features."
