Introduction to asav9-14-2-14.vhd.bz2
The asav9-14-2-14.vhd.bz2 is a specialized virtual hard disk package for deploying Cisco Adaptive Security Virtual Appliance (ASAv) on Microsoft Azure cloud infrastructure. As part of Cisco’s ASA Software 9.14(2) release cycle, this compressed VHD format (version 9.14.2.14) provides enterprise-grade firewall capabilities in cloud environments while maintaining parity with physical ASA appliance features. The “.vhd.bz2” extension indicates its dual-layer compression optimized for Azure Marketplace distribution.
This build supports Azure Resource Manager (ARM) deployment models and integrates natively with Azure Security Center for unified threat management. Designed for virtual network security groups, it enables micro-segmentation policies and east-west traffic inspection within Azure virtual networks.
