Sentiment score
8.0

System admin at Environment Fund
I have seen a return on investment with Trellix Collaboration Security; specifically, money was saved and fewer employees were needed because I do not need employees on different sites.
Network & Security Lead at Net-International
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 have seen a return on investment from using Trellix Collaboration Security as we have saved time and reduced security incidents, improving our overall effectiveness.

Featured Reviews

Abhimanyu Das - PeerSpot reviewer
Senior Cybersecurity Engineer at Kyndryl
Targeted email filtering has reduced spam and phishing and now saves significant investigation time
The best features of Fortinet FortiMail include its techniques and tactics, which are highly effective compared to other solutions such as Microsoft 365. Although Fortinet FortiMail may not be as advanced in some aspects, it is well recognized for its strong performance in handling spam and phishing. It performs thorough mail scanning and also offers a sandboxing feature that enhances protection. Fortinet FortiMail has had a positive impact on my organization by significantly reducing unwanted email activities such as spam and phishing. It provides accurate detection and generates results that often exceed what can be achieved through manual analysis. Since deploying Fortinet FortiMail, I have observed a reduction in investigation time by at least 20 to 30 percent.
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.
