Introduction to Cisco_Secure_Firewall_Threat_Defense_Virtual-7.7.0-89.qcow2
The Cisco_Secure_Firewall_Threat_Defense_Virtual-7.7.0-89.qcow2 is the KVM-optimized virtual machine image for Cisco’s Next-Generation Firewall (NGFW) in private cloud environments. Released on March 5, 2025, this version delivers unified threat prevention for hybrid infrastructures through its integration of stateful firewalling, NGIPS, and TLS 1.3 decryption capabilities.
Designed for VMware ESXi 6.5-8.0 and KVM hypervisors, this QCOW2 format package enables deployment of virtual firewalls with consistent security policies across physical and cloud environments. Cisco engineers prioritized operational stability in this release, particularly for financial institutions managing encrypted transaction traffic.
