Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. 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. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

SOC Team Lead at a security firm with 51-200 employees
Centralized protection has transformed email security and incident investigations by reducing false positives and improving behavioral threat detection
The challenges include the challenge of finalizing a product that has all the security features or capabilities that are usually required. For example, if there is an EDR platform that's just monitoring IDS signatures, it won't be as beneficial as one with behavioral monitoring and other critical aspects required according to the best practices of the industry. Additionally, if there is a product that can provide a centralized view Trend Vision One does, it really grabs the customer's interest because customers usually don't have to buy separate EDR, XDR, or SIEM solutions or a console for their SOC analyst or email security team. These challenges consist of managing multiple teams and products. Trend Micro Email Security comes in and solves these problems.Trend Micro Email Security is generally a bit more difficult to implement compared to the rest of the solutions such as network security modules or EDR modules, which are much easier. Trend Micro Email Security has some complexities in implementation, but there aren't any significant shortcomings that require Trend Micro to improve.

Quotes from Members

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

Pros

"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"It's very easy to deploy and configure."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"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."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"The product offers protection, email security, anti-spam, and antivirus."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
More Cisco Secure Email Threat Defense pros
"The solution's most valuable feature is ATP (Advanced Threat Protection), which utilizes the machine learning algorithm."
"Trend Vision One is one of the best XDRs that has been introduced to the market, with almost 14 applications integrated into a single console, including mobile device management, network security, endpoint security, and cloud app security, all with a really good GUI."
"Some people can hack our system by sending emails from our domain to our domain. This is blocked completely by Trend Micro."
"The tool provides a strong defense against attacks. It is also easy to use. Trend Micro Email Security's integration capabilities are great."
"The email and the signature based protection is the most valuable feature."
"The most valuable features of this solution are the antivirus, antispam, and integration with cloud services. This is a multifunctional solution."
"The product is quite strong, and that is one reason most clients are replacing their existing email security solutions with it."
"It does a good job of ensuring users are not compromised via email."
More Trend Micro Email Security pros
 

Cons

"The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
"This solution could be improved by integration with Sandbox."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"The pricing could always be better."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"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."
More Cisco Secure Email Threat Defense cons
"There is room for improvement in mobile device management. The company also needs to work on pricing because it is quite costly compared to other products."
"For support from Trend Micro, I would give maybe 20%."
"The only negative thing about Trend Micro Email Security is its price. It could be less expensive."
"What I dislike is that I cannot change the spam score. The only changes available are low, very low, and high."
"Trend Micro Email Security has integrated AI features recently, but the more the learning of their AI engines will yield much better results."
"In terms of improvement, reducing false positives would improve the system."
"In our company, we found out that the solution wasn't well-tested by Trend Micro, resulting in a performance and bandwidth problem."
"It is a bit expensive than the market price."

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."
"It is expensive compared to other vendors."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"It's a VPN solution. Trend Micro is reasonably priced."
"Trend Micro Email Security's pricing is reasonable."
"The cost is about $6,000 for 300 users for one year."
"The price of Trend Micro Email Security is more than Sophos' similar solution."
"The tool must improve its pricing."
"The price of Trend Micro Email Security is annual. There are no additional fees."
"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."
"The price is more accessible compared to some other solutions, like FortiMail. It offers excellent value for the price."
