Introduction to asav9-19-1-5.zip Software

The asav9-19-1-5.zip package contains Cisco’s Adaptive Security Virtual Appliance (ASAv) software designed for VMware and hybrid cloud deployments. This release (version 9.19.1-5) provides critical security updates and infrastructure optimization for virtualized firewall implementations. As part of Cisco’s 9.19.x software train, it maintains backward compatibility with Firepower 2100/4100 hardware platforms while introducing enhanced virtualization capabilities.

The “.zip” extension confirms this compressed archive contains OVA templates and configuration files optimized for VMware ESXi 7.0U3+ and vSphere 8.0 environments. Cisco officially released this maintenance update in Q1 2025 to address CVEs from Security Advisory 2024-ASA-019 and improve cluster deployment efficiency.
