Featured Reviews

John Rallo - PeerSpot reviewer
Offers excellent visibility into vulnerabilities and the attack surface itself
Attack surface reduction and limiting attack surface vectors are valuable features. It's helpful to isolate specific devices and get super granular with the features they offer. The visibility into the attack surface is good. It gets highly granular. I don't work on that side, but the people who do tell me they get more visibility.
MohammadAlshatreet - PeerSpot reviewer
Resolve support issues promptly while optimizing system resource usage
I use the solution primarily for scanning and identifying threats, which is essential in determining the percentage of resources used, such as CPU and hard disk. It's important to balance resource consumption to maintain operational efficiency. Furthermore, the incident response capabilities allow me to resolve authentication and support issues promptly, ensuring the system operates without downtime.
Abdullah Al Hadi - PeerSpot reviewer
Customization capabilities allow clients to autonomously deploy policies
There are a few areas where Trellix Endpoint Security ( /categories/endpoint-protection-platform-epp ) can improve. Firstly, the high CPU utilization when agents are installed can negatively impact client systems. Another issue is with end-users outside the network, where the agent handler sometimes fails to deploy the product properly. Improvements are needed in forensic analytics to detect specific vulnerabilities. It would also help if detection specifics were identified more quickly and the problem-solving process accelerated, especially to meet larger clients' expectations.
