Cisco Firepower is a unified security solution that combines firewall, intrusion prevention system (IPS), advanced malware protection (AMP), and threat intelligence features. Cisco ASA is a traditional firewall that focuses on network traffic control based on packet filtering and stateful inspection. One of the key differences between Cisco Firepower and Cisco ASA is that Cisco Firepower natively provides intrusion prevention capabilities while Cisco ASA does not. Intrusion prevention is the process of detecting and blocking malicious network traffic before it reaches the intended target. Cisco Firepower uses a combination of signature-based and behavior-based detection methods to identify and stop known and unknown attacks. Cisco ASA, on the other hand, does not have built-in intrusion prevention capabilities. It can only perform basic packet inspection and filtering based on predefined rules. To enable intrusion prevention on Cisco ASA, an additional module called FirePOWER Services is required. This module integrates Cisco Firepower features into Cisco ASA, but it is not the same as Cisco Firepower itself. Cisco Firepower offers more advanced and integrated security features than Cisco ASA with FirePOWER Services123. References: 1: Cisco ASA vs Cisco Firepower | What are the differences? - StackShare 2: Cisco FTD vs ASA: Difference and Comparison 3: CISCO FIREPOWER VS.
