Helpful support, and useful dashboards
They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward. I haven't tried it in a while since then. Since I can't turn it off on a per-user basis, I had to turn it off globally. I have certain exceptions for not doing the sanitization, and how to set those up is not intuitive. It would be useful if there were a better way of doing that. Using digital certificates is hard. It would be better if it used Windows Servers' built-in certificate management.

Endpoint protection has strengthened network control and has simplified global threat response
In my opinion, the best features Trellix Collaboration Security offers include the firewall, the on-access scan, and the ability to obtain daily signatures for the latest malware. These daily signatures, referred to as content, ensure that we are protected against the most recent malware threats recognized by other companies. Another feature I particularly enjoy is the capability to maintain different locations that can communicate with the fabric, or DXL fabric as I refer to it, allowing me to create something akin to an EDR for immediate responses to resolve issues. The DXL fabric has helped my organization by enabling communication between different locations, such as one in Europe, another in South America, and one here. This fabric communicates with a broker that interacts with the TIE servers, which maintain the reputation of files, certificates, and known signatures from various regions including Europe, South America, and Canada. When something suspicious occurs, such as a certificate appearing malicious on an application, I can easily click and indicate that I trust this file, and through the fabric, I can apply an exclusion for that application across all locations simultaneously. Other features I find valuable include the SSO integration with Trellix EPO, specifically SAML SSO, allowing people not to have to manage usernames and passwords if they already utilize an SSO service for SAML; I consider this functionality to be quite beneficial.

Quotes from Members

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

Pros

"The most valuable feature of MetaDefender Email Security is the CDR. Customers purchase this solution specifically for data communication, as the other features can be obtained through other technologies that most customers already possess. Therefore, data communication serves as the foundation for the platform."
"The most valuable feature is called summary reconstruction which is used to deliver encrypted files to users."
"The sanitization is very good."
"FireEye ETP has blocked several campaigns that lead to the post compromise deployment of ransomware, Obfuscated Outlook Phishing impersonation, Attachment based Phishing."
"We have had very good results from the use of FireEye Email Security. We are very comfortable with this technology, but I don't know if it's necessary to move into the cloud, we will check other technologies and study them. Additionally, the solution has good integration."
"After implementing Trellix Collaboration Security, we have not encountered any incidents related to ransomware."
"It is one of the greatest solutions to have or to complement any other security solution such as Proofpoint or IronPort."
"Trellix Collaboration Security has positively impacted our organization by making our collaboration environment very safe, allowing our team to share files and links without worrying about threats."
"The product protects my email."
"The auto-remediation feature is valuable."
"Trellix Collaboration Security has positively impacted my organization by improving security, making teamwork more effective, and ensuring collaboration has become smoother."
 

Cons

"They offer a feature called SmartLink neutralization. I have tried it before. It seemed to work most of the time; however, I had a few users for whom it just wouldn't work. Whenever they click on a link, it stays on the MetaDefender page, saying that it's scanning it and never moves forward."
"The DLP should be upgraded and has room for improvement."
"Although the number of AV engines is good, it could be better."
"If you really need something powerful to handle multiple routes and delivery points then this solution might not be for you."
"Support services need enhancement. The existing support team is derived from both McAfee and FireEye, with FireEye having been more adept in support."
"I deduct two points because while we are using it for insiders, we still rely on another solution for gateway level security, which makes us use two different solutions for the same purpose."
"The solution needs better support."
"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
"There is a need for improved integration with totally different products, such as a rapid server."
"I would like the solution to be able to automatically quarantine the malicious emails before getting to the user's mailbox and continue with regular email operations. This could result in the user clicking the email before the purge operation is completed."
"The custom tailoring is limited."
 

Pricing and Cost Advice

"According to our customers, the price of MetaDefender is high and it continues to increase by almost 15 percent each year."
"The cost is very high."
"The licensing is on a yearly basis."
"The solution requires a license to be purchased for every user."
"I rate the product price as nine out of ten, where ten is the most expensive, and one is the cheapest. There is no need to pay any extra charges apart from the licensing costs."
