Introduction to cisco-asa-fp2k.9.19.1.37.SPA

The cisco-asa-fp2k.9.19.1.37.SPA firmware delivers critical security maintenance for Cisco Firepower 2100 Series appliances running Adaptive Security Appliance (ASA) software. As part of Cisco’s Extended Maintenance Release (EMR) cycle, this version focuses on resolving 14 CVEs identified in previous builds while optimizing threat inspection performance for hybrid cloud environments.

Designed specifically for Firepower 2100 hardware platforms (FPR 2120/2130/2140), this package integrates next-generation firewall capabilities with enhanced VPN throughput. Cisco’s security advisories confirm this build was published in Q3 2024 as a transitional update between major feature releases, prioritizing operational stability for high-availability deployments.
