Introduction to “cisco-asa.9.14.4.7.SPA.csp” Software

The ​​cisco-asa.9.14.4.7.SPA.csp​​ is Cisco’s security-focused firmware update for Firepower 2100 Series appliances operating in ASA mode, released on October 15, 2025 as part of the 9.14(4) Extended Maintenance Release (EMR). This interim build resolves 14 CVEs while maintaining backward compatibility with FPR-2110/2130/2140 hardware platforms manufactured after Q2 2023.

Designed for organizations requiring sustained operational stability, this version introduces hardware-assisted TLS 1.3 acceleration for Firepower 2140’s 400Gbps interfaces and improves cluster synchronization efficiency. The “.csp” extension confirms this package as a Consolidated Security Patch bundle for ASA platforms running FXOS 2.14+.
