Trellix Endpoint Security (ENS) Firewall protects systems, network resources, and applications from external and internal attacks.
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.
