Introduction to cisco-asa-fp3k.9.20.3.SPA

The ​​cisco-asa-fp3k.9.20.3.SPA​​ is a critical firmware package for Cisco Secure Firewall 3100/4200 series appliances running Adaptive Security Appliance (ASA) software. Released in Q3 2024 as a security maintenance update, this build addresses 14 CVEs identified in previous versions while enhancing hardware compatibility for SSP-60/SSP-120 security modules. Designed for enterprise networks requiring TLS 1.3 enforcement and cluster scalability, it supports deployments of up to 16 nodes in high-availability configurations with 25% improved threat inspection throughput compared to 9.18.x versions.

This firmware maintains backward compatibility with ASA 9.20.x policy templates and integrates with Cisco SecureX platform threat intelligence feeds. The package includes mandatory platform version 3.4.1.217 updates for Firepower 4200 hardware revisions manufactured after 2023.
