These are the foundational elements that enable Cisco FirePOWER to provide advanced network security, threat detection, and comprehensive protection:

• FirePOWER Threat Defense (FTD): The unified software image that runs on Cisco FirePOWER and Firepower-enabled ASA devices. FTD integrates next-generation firewall, intrusion prevention, URL filtering, application control, and advanced malware protection in a single solution.
• Firepower Management Center (FMC): The centralized management console for administering, configuring, and monitoring Cisco FirePOWER appliances and features. FMC provides a single interface for policy management, event analysis, device health monitoring, and detailed reporting.
• Intrusion Prevention System (IPS): Offers deep packet inspection and advanced threat detection using signature- and behavior-based analysis. IPS can block, allow, or alert on observed threats in network traffic, helping to stop exploits and attacks in real time.
• Advanced Malware Protection (AMP): Provides continuous analysis and retrospective security. AMP tracks files across the network, identifies malicious files (even after delivery), and helps remediate infections through detailed visibility and forensic information.
• Application Visibility and Control (AVC): Identifies and controls application usage within the network. AVC increases security posture by enforcing policies for specific applications or categories, regardless of port or protocol.
• URL Filtering: Allows organizations to control and monitor user access to websites based on content categories, regulatory requirements, or security policies. URL filtering blocks access to malicious or inappropriate sites, reducing risk from web-based threats.
• Cisco Talos Threat Intelligence: Powers FirePOWER’s dynamic threat defense with real-time intelligence from Cisco Talos. This component delivers up-to-date information on new threats, vulnerabilities, and attack campaigns, enabling FirePOWER to rapidly adapt and respond to the threat landscape.
