Featured Reviews

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.
Andras Solt - PeerSpot reviewer
Reasonable pricing and good spam filtering but does not offer robust gatekeeping
It's mainly suited for mid-size companies, not for bigger companies like us. We are more than 1,000 people. In fact, we're over 2000 users, so that's why we investigated some other products, and Clearswift, for example. We likely won't increase usage. We're looking at GFI in a year or so.
Bruno Obata - PeerSpot reviewer
Provides effective filtering for spam, phishing, and suspicious emails
In terms of improvement, reducing false positives would improve the system. If there were fewer false positives, it would be nearly perfect. In the next release, I would like to see improved detection for emails containing only text, especially if they seem suspicious but lack links or attachments. Currently, Trend Micro Email Security is effective with emails containing links or attachments, but those with only text can slip through unnoticed.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Microsoft Defender has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"Microsoft Defender for Office 365 facilitates efficient management and updates through the cloud. We do not have to worry about incompatibilities. It just works."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"The initial setup was easy."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"It has a very high level of security through special licensing with solutions like FortiGuard, sandboxing solutions in the cloud, and URL rewriting solutions."
"The product helps users handle security challenges as it offers prefiltering options and does relatively good incident reporting."
"The spam filtering is great."
"Troubleshooting is very simple because you can see where the email was not delivered and why it would be considered as spam."
"Its threat detection capabilities have been beneficial."
"The key benefits of this solution are its user-friendly interface and clear instructions, as well as the wealth of online resources and helpful health community available for support. These features make it easy for users to navigate and utilize the solution effectively."
"The most valuable features of this solution are anti-spam, sender reputation, and antivirus."
"Fortinet FortiMail's most valuable features are its performance and security."
"The most valuable features include email filtering to block spam and phishing attempts, the use of DMARC for email authentication, and robust malware scanning."
"The solution's initial setup process was easy since it was deployed on the cloud."
"The email and the signature based protection is the most valuable feature."
"The most valuable features of the solution are spam protection and email continuity."
"The most valuable feature of Trend Micro Email Security is effective phishing prevention."
"Some people can hack our system by sending emails from our domain to our domain. This is blocked completely by Trend Micro."
"Since implementing it, we've seen a significant improvement in security. We no longer receive spam emails, and we're protected from various cyberattacks, including ransomware and social engineering."
"The solution's most valuable feature is ATP (Advanced Threat Protection), which utilizes the machine learning algorithm."
 

Cons

"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"The visibility for the weaknesses in the system and unauthorized access can be improved."
"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."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"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."
"Microsoft sometimes has downtime, and we'll get several incidents coming in back to back. We have a huge backlog of notifications, many of which may be false positives. However, there might be serious alerts, so we can't risk dismissing all of them at once."
"Configuration at the mid-level could be improved for the support team."
"The sandboxing features are not well done in Fortinet FortiMail, making it an area of improvement."
"The solution could improve by making the UI more user-friendly and increasing spam and threat detection capabilities."
"The Ui isn't that intuitive."
"The solution could be improved by providing a virtual machine facility with a complete set of options in the VM setup."
"The solution doesn't scale easily."
"Maybe FortiMail's integration could be better."
"FortiMail's dashboard is somewhat complex and could be made simpler."
"It would be nice if we could manage the solution from the cloud so I could handle things off-site if necessary."
"The enterprise security feature needs improvement."
"The product must provide better customization features."
"They need to adjust the spam filtering and make it stronger."
"Trend Micro Email Security can improve on scam detection. It could use AI in this area."
"The initial setup was straightforward. This is a virtual appliance, it takes a short time to deploy the solution. However, it is not difficult if you understand the technology. You must have good knowledge of the email security area to set up the product correctly. There are many features in this solution and a high risk of having mistakes with the configuration."
"Sometimes malicious email gets past the email gateway."
"The tool's dashboard is old."
"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."
