Cisco Firepower deployment modes are the methods to insert a Firepower into the network as a Firewall/IPS device or as a IPS-only device. In Firewall/IPS mode, you have the option to choose routed or transparent mode and as a IPS-only device you can choose between inline and passive mode. We discussed routing mode and transparent mode in the previous sections. In this section, we will discuss IPS-only inline and passive modes.
