John Zupancic - PeerSpot reviewer
Vice President / Branch Manager / Senior Technician at Aperion Information Technologies, Inc.
Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.
Jorge Abalo - PeerSpot reviewer
Endpoint Security Analyst at BNP Paribas
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

"They are very easy to use."
"It's easy to use and user-friendly. Users can also easily release spam emails."
"They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried."
"The accessibility is one of the features that I love; we can control it from the cloud and we can access it from anywhere."
"One of the most valuable features is the protection against vulnerabilities, particularly through virtual patching."
"The auto-remediation feature is valuable."
"The solution's most valuable feature is its simplicity. It's very user-friendly."
"I rely on Trellix Collaboration Security because the sensors are highly reliable and high-performance sensors that can handle traffic efficiently."
"The product protects my email."
"Trellix Collaboration Security has positively impacted my organization by improving security, making teamwork more effective, and ensuring collaboration has become smoother."
"Many similar solutions don't normally protect clients from malware, but FireEye does a very good job of protecting systems."
 

Cons

"Technical support is no longer as good as it once was."
"Email security checks contain a small number of false positives."
"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"The reporting aspect of the solution needs improvement."
"Trellix Collaboration Security can be improved by making the reporting and analysis tools more detailed."
"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."
"If they want to be the primary or best solution, they need to have better email management features."
"We're not really that satisfied with technical support. They are too slow to respond."
"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 custom tailoring is limited."
"The solution must provide features to scan QR codes for threats."
 

Pricing and Cost Advice

"I can rate it five out of ten because there are different platforms that also offer the same services for lower prices. But AppRiver is more flexible."
"They're fairly inexpensive, but they're right in the ballpark of most of the other online products like that."
"The solution requires a license to be purchased for every user."
"The licensing is on a yearly basis."
"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."
"The cost is very high."
