Introduction to asav9-16-4-14.qcow2 Software

The ​​asav9-16-4-14.qcow2​​ represents Cisco’s Q4 2024 maintenance release for its Adaptive Security Virtual Appliance (ASAv) firewall platform. This QCOW2-format virtual machine image enables deployment of enterprise-grade firewall services in virtualized environments including VMware ESXi, KVM hypervisors, and cloud infrastructure.

Designed as the software foundation for Cisco’s virtual firewall solutions, this build implements:

  • Stateful inspection firewall services
  • VPN termination (IPsec/IKEv2/SSL)
  • Application-aware threat prevention
  • Integration with Cisco SecureX threat intelligence platform

Compatibility extends to all ASAv series virtual appliances (ASAv10/30/50/100) running on x86_64 virtualization platforms. The “9.16(4)14” version designation confirms this as a Long-Term Support (LTS) release with extended maintenance through 2026.
