Introduction to ftd-fi-device-pkg-1.0.5.2.zip
This device package enables FlexConnect integration for Cisco Secure Firewall 3100/4100 Series appliances running Firepower Threat Defense (FTD) 7.0+ software. Released in Q2 2025 as part of Cisco’s quarterly maintenance cycle, it provides centralized policy enforcement for distributed branch deployments while maintaining local traffic inspection capabilities.
The software implements Zero Trust Network Access (ZTNA) principles through encrypted TLS 1.3 tunnels between branch appliances and FlexConnect hubs. Compatible with Firepower 4140/4150/4160 hardware platforms, it supports simultaneous management of up to 200 remote nodes through Firepower Management Center (FMC) 7.7+ control planes.
