Cisco users with Firepower Threat Defense (FTD) on an Adaptive Security Appliance (ASA) are running SNORTⓇ, our open-source intrusion protection system, under the hood, along with a suite of other Talos-fueled security processes. Snort monitors traffic by sniffing packets and comparing their contents against tens of thousands of rules written to find all kinds of malware and other malicious activity. Our analysts are constantly creating new rules to cover vulnerabilities in a wide range of products. The highly active open-source community around Snort adds rules for general and niche network configurations, as well.
