Introduction to asav9-14-4-22.qcow2

This QCOW2 format virtual appliance delivers Cisco Adaptive Security Virtual Appliance (ASAv) version 9.14(4)22 for KVM and VMware environments. Released in Q2 2024, it provides enterprise-grade firewall capabilities in virtualized infrastructures, supporting up to 10Gbps throughput with full feature parity to physical ASA 5500-X series firewalls. The ASAv platform enables security policy consistency across hybrid cloud deployments and Cisco ACI fabric environments.

Designed for service providers and large enterprises, this virtualization-optimized build supports dynamic scaling of security resources in OpenStack, VMware vSphere, and Microsoft Hyper-V environments. It maintains compatibility with Cisco Firepower Management Center for unified threat management while operating as a standalone virtual firewall.
