The product that allows Cisco FMC to push security intelligence observable to its sensors from other products is Threat Intelligence Director (TID). TID is a feature of Cisco FMC that enables you to integrate third-party threat intelligence feeds into your security policies. TID collects, aggregates, and correlates observables from multiple sources, such as Cisco Talos Intelligence, Cisco Umbrella, and other external providers. TID then pushes the observables to the sensors that are managed by FMC, such as Firepower Threat Defense (FTD) devices, Firepower appliances, and Cisco Secure Firewall Cloud Native. The sensors can then use the observables to block or monitor traffic based on the reputation and threat level of the IP addresses, URLs, and domains12.
