Introduction to cisco-asa.9.16.4.18.SPA.csp Software
The cisco-asa.9.16.4.18.SPA.csp is Cisco’s maintenance release for Firepower 2100 series security appliances running Adaptive Security Appliance (ASA) software. Officially released in Q4 2024, this 387MB package addresses 14 critical CVEs while enhancing interoperability with Cisco Secure Firewall Management Center 7.6+. Designed for enterprise edge security deployments, it supports hardware-accelerated IPsec throughput up to 2.8Gbps on FPR-2120/2140 models.
This version maintains backward compatibility with ASA 9.14.x configurations while introducing enhanced TLS 1.3 inspection capabilities. The “.csp” extension confirms its deployment through Cisco Security Packager format, optimized for FXOS 2.10.1+ platforms.
