Introduction to asav9-12-4-67.qcow2

The asav9-12-4-67.qcow2 file contains the disk image for Cisco Adaptive Security Virtual Appliance (ASAv) version 9.12(4)67, designed for KVM/QEMU-based virtualization platforms. This QCOW2 format virtual machine template enables deployment of Cisco’s enterprise-grade firewall capabilities in private cloud environments and NFV infrastructures.

Released in March 2025 under Cisco’s quarterly security maintenance cycle, this build provides enhanced cryptographic standards compliance for government and financial sector deployments. It supports OpenStack Stein through Yoga releases and integrates with Cisco Security Manager 4.23+ for centralized policy management.
