Introduction to asav-esxi.ovf

The asav-esxi.ovf represents Cisco’s Open Virtualization Format template for deploying Adaptive Security Virtual Appliance (ASAv) on VMware ESXi hypervisors. This standardized package simplifies enterprise firewall deployment in virtualized environments while maintaining compatibility with VMware’s vSphere ecosystem. The template contains preconfigured security parameters optimized for ESXi 6.7U3+ environments, enabling rapid deployment of virtual firewall instances with integrated threat prevention capabilities.

As part of Cisco’s ongoing security infrastructure modernization, this OVF package supports hybrid cloud architectures through native integration with VMware NSX-T network virtualization platforms. System administrators can leverage this template to enforce consistent security policies across both on-premises and cloud-based workloads.
