Stable, but malware needs improvement and customer support is poor
They need to improve the malware in the product. I am not satisfied with Clearswift because of the lack of customer support. The support is poor, the supplier takes a lot of time and it's expensive. We have some issues here when I contact the supplier, it takes a lot of time for them to get back to us but there's no solution. I am now looking at Symantec as a possible alternative.

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

"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
"Go for it! I think it's an excellent product with great technical support."
"We use a few features for web proxy, and another feature is the email content filter and malware for our internal policy in the email content."
"I find the anti-phishing and anti-spam features most valuable because they reduce false positives and enhance security."
"Trend Micro Email Security [EOL] prevents that from happening with its advanced detection mechanisms."
"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."
"It is mostly stable."
"The solution's most valuable feature is ATP (Advanced Threat Protection), which utilizes the machine learning algorithm."
"The email and the signature based protection is the most valuable feature."
"Trend Micro constantly releases new versions and patches based on evolving needs."
"I have seen a huge decrease in phishing emails and spam being received by end users, with about 80% of observed spam and phishing emails being reduced."
 

Cons

"Malware needs improvement."
"I am not satisfied with Clearswift because of the lack of customer support."
"FTP server and TRUST Manager functionality."
"As a SOC analyst and from an enterprise security perspective, Trend Micro Email Security [EOL] is already strong. However, I would focus on improving visibility, detection tuning, response automation, and identity-based BEC protection, rather than simply adding more blocking rules."
"While they are good, not 100% of email is protected just yet."
"The patch management could improve in Trend Micro Email Security."
"There is room for improvement in threat detection, especially for advanced attacks and business email compromise."
"To be frank, at the current moment, we are not happy with Trend Micro Email Security [EOL], and that is why we moved forward with Mimecast."
"The solution does not check scam emails which is a critical need for our customers."
"The solution's interface, which we get from an admin perspective, sometimes gets confusing."
"I think when incidents occur with Trend Micro Email Security [EOL], the support should be a bit faster with response times."
