Introduction to cisco-asa-fp2k.9.16.3.14.SPA Software
This software package delivers Cisco’s Adaptive Security Appliance (ASA) operating system for Firepower 2100 series next-generation firewalls. Designed as a critical security maintenance release, version 9.16.3.14 addresses vulnerabilities identified in Cisco’s Q3 2024 security advisories while maintaining backward compatibility with Firepower 2100 hardware platforms (FPR-2110/2120/2130/2140 models).
Cisco released this interim build in February 2025 to resolve stability issues in high-availability cluster configurations, aligning with NIST SP 800-193 firmware resilience guidelines. The package integrates with Cisco SecureX threat intelligence platforms, enabling unified policy enforcement across hybrid network environments.

Post-installation verification commands:
show version | include 9.16.3.14
show inventory chassis | grep "FPR-21[1-4]0" This software requires active Cisco SMART Net Total Care Service coverage for deployment validation. Unauthorized distribution violates Cisco’s End User License Agreement (EULA) and may trigger Smart Licensing compliance audits.
Note: All Cisco ASA software downloads require cryptographic signature validation via the verify /sha512 command prior to installation.
