Trellix Endpoint Security (ENS) for Linux Firewall is a security solution that protects your environment against known and unknown threats.
Firewall scans all incoming and outgoing traffic and compares it to its list of firewall rules, which is a set of criteria with associated actions. If a packet matches all criteria in a rule, the firewall acts according to the rule, blocking or allowing the packet through the firewall.
You use ePO - On-prem to deploy and manage Firewall on client systems.
