The REST API is a powerful tool for customers using either proprietary management platforms or firewall policy management (FPM) and network security policy management (NSPM) solutions from vendors like AlgoSec, FireMon, Skybox, and Tufin. FPM, NSPM, and similar technologies can use the read and write functions of the API to perform a wide range of management functions. These range from complete policy migration to working with specific Cisco Firepower elements such as audit records, device and group information, physical interfaces, and virtual switches.
