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.

Stable and scalable solution with a great threat isolation engine
Menlo Security RBI is mainly used to do basic cloud migrationary technologies Menlo Security RBI's best feature is its threat isolation engine. Menlo Security RBI could be more cloud-friendly, and its mobility could be improved. In the next release, I'd like Menlo Security RBI to include a…

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.

Quotes from Members

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

"The deployment capability is a great feature."
"The product is not resource-intensive."

"Menlo Security RBI's best feature is its threat isolation engine."
"The most valuable features of this solution are the antivirus, antispam, and integration with cloud services. This is a multifunctional solution."
"The email and the signature based protection is the most valuable feature."
"The product is quite strong, and that is one reason most clients are replacing their existing email security solutions with it."
"Trend Micro Email Security scans all email attachments because, nowadays, ransomware or malware files are sent through email attachments."

Cons

"The phishing and spam filters could use some improvement."

"The XDR dashboard has room for improvement."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."

"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
"There are several features, such as supporting web technologies, that the company is working on implementing in the platform. There are a lot of backend web technologies in use on various websites, for example, two-way audio/video and WebGL, for which support may not be fully implemented in the product."
"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."
"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 send box needs improvement to match other products."
"Trend Micro Email Security could improve by advancing its artificial intelligence in email security. There are rules that have to be configured. There should be less configuring."
 

Pricing and Cost Advice

"The product is very expensive."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"Menlo Security RBI can be very costly."
"Price-wise, it is a cheap solution. I rate the solution's pricing a one on a scale of one to ten, where ten is expensive. Annual payments are made for the licensing."
"Trend Micro Email Security's pricing is reasonable."
"It's a VPN solution. Trend Micro is reasonably priced."
"The price is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
"The cost is about $6,000 for 300 users for one year."
"Trend Micro Email Security is not an expensive solution."
"It is expensive. The cost is per box, and it depends on how big your environment is. Prices range from 11 to 12 dollars for licenses and can fluctuate up and down, but for environments with 4,000 to 5,000 users, it can be between 6 to 8 dollars."
"The price of Trend Micro Email Security is annual. There are no additional fees."
