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

"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"With both of them working together, we have the perfect solution for mail."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"After implementing Trellix Collaboration Security, we have not encountered any incidents related to ransomware."
"One of the valuable features of the product stems from the fact that it is easy to implement the tool in our environment."
"One of the most valuable features is the protection against vulnerabilities, particularly through virtual patching."
"I rely on Trellix Collaboration Security because the sensors are highly reliable and high-performance sensors that can handle traffic efficiently."
"FireEye Email Security is easy to use."
"We can control this solution from the cloud and are able to access it from wherever we are."
"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."
"The initial setup is simple."
 

Cons

"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The solution is not 100 percent stable and that can use improvement."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"I would rate them as a 1.5. The new hub created in India is not good."
"If you really need something powerful to handle multiple routes and delivery points then this solution might not be for you."
"I observe that the return on investment is hindered by the lack of adequate training opportunities, with Trellix's own training being quite costly, ranging from 2,000 to 4,000 dollars, which many small or medium-sized businesses cannot afford."
"I chose a nine out of ten because some improvements are required, especially concerning East-West traffic or zero-day vulnerabilities."
"The spam detection feature could be better."
"The reporting aspect of the solution needs improvement."
"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."
 

Pricing and Cost Advice

"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"The solution is not expensive."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"My company makes annual payments towards the licensing costs solution."
"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 solution requires a license to be purchased for every user."
"The cost is very high."
"The licensing is on a yearly basis."
