Nadeem Syed - PeerSpot reviewer
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:
 

Pros

"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"I highly recommend it as one of the best choices."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"Secure Email Threat Defense's scalability is good."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"The solution is stable."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"This solution is easy to use."
"The most valuable features of the solution are spam protection and email continuity."
"The solution's most valuable feature is ATP (Advanced Threat Protection), which utilizes the machine learning algorithm."
"Trend Micro Email Security’s most valuable feature is spam filtering."
"Trend Micro constantly releases new versions and patches based on evolving needs."
"The most valuable features of this solution are the antivirus, antispam, and integration with cloud services. This is a multifunctional solution."
"Trend Micro has inter-domain security features that solutions from other vendors like Forcepoint lack."
"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 pricing could always be better."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"The physical appliance has been discontinued, although the platform still exists."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"The solution is a bit expensive."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"The patch management could improve in Trend Micro Email Security."
"The solution's configuration policy should be easier."
"They need to adjust the spam filtering and make it stronger."
"In our company, we found out that the solution wasn't well-tested by Trend Micro, resulting in a performance and bandwidth problem."
"Trend Micro Email Security should introduce new features, improvements, and updates which are cost-effective and easy to deploy."
"The tool's dashboard is old."
"Trend Micro Email Security can improve on scam detection. It could use AI in this area."
"There is room for improvement in threat detection, especially for advanced attacks and business email compromise."
 

Pricing and Cost Advice

"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The solution’s pricing is manageable."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"The price of Trend Micro Email Security is more than Sophos' similar solution."
"The tool must improve its pricing."
"Trend Micro Email Security is not an expensive solution."
"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."
"The solution's pricing is very optimum, given its quality, features, and stability."
"I rate the product price a six on a scale of one to ten, where one is low price and ten is high price."
"The price is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
