About Firepower Threat Defense with FDM
The FTD provides next-generation firewall services, including stateful firewalling, routing, VPN, Next-Generation Intrusion Prevention System (NGIPS), Application Visibility and Control (AVC), URL filtering, and Advanced Malware Protection (AMP).
You can manage the FTD using the Firepower Device Manager (FDM), a simplified, single device manager included on the device. Use HTTPS to the Management interface that you allocated to the FTD logical device.
For troubleshooting purposes, you can access the FTD CLI using SSH on the Management interface, or you can connect to the FTD from the FXOS CLI.
