What is Sourcefire?

Sourcefire was a network security company known for its intrusion detection and prevention systems (IDS/IPS). Acquired by Cisco in 2013, the technology is now integrated into Cisco's security solutions, such as the Firepower Next-Generation Firewall (NGFW). It is commonly used for identifying and blocking malicious network activity, protecting against vulnerabilities, and providing visibility into network traffic. The core of Sourcefire's technology revolves around its Snort intrusion detection engine.
