Introduction to Cisco_Secure_Firewall_Threat_Defense_Virtual-7.2.3-77.tar.gz
The Cisco_Secure_Firewall_Threat_Defense_Virtual-7.2.3-77.tar.gz is an official VMware ESXi deployment package for Cisco Secure Firewall Threat Defense Virtual (FTDv) 7.2.3, designed to deliver next-generation firewall capabilities in virtualized environments. Released in Q3 2024, this version provides enhanced interoperability with VMware vSphere 8.0 and introduces critical security patches for TLS 1.3 traffic inspection workflows.
This software enables organizations to deploy enterprise-grade threat prevention, intrusion detection, and application visibility in hybrid cloud architectures. It supports both standalone and clustered deployments on VMware ESXi 6.5–8.0 hypervisors, making it ideal for securing dynamic workloads across private data centers and public clouds.
Key Features and Improvements
Version 7.2.3-77 focuses on operational stability and cloud-ready security:
- TLS 1.3 Decryption Optimization: Reduces latency by 22% during encrypted traffic inspection through improved Snort 3.1 rule processing.
- VMware vSphere 8.0 Support: Validates compatibility with VMware’s latest hypervisor features, including vMotion and Distributed Resource Scheduler (DRS).
- HA Cluster Enhancements: Fixes synchronization failures in multi-node Firepower 9300 virtual clusters.
- Security Compliance: Addresses CVE-2024-20351 (Snort false-positive traffic drops) and CVE-2024-20370 (FXOS privilege escalation).
The update retains backward compatibility with Firepower Management Center (FMC) 7.2.x policies while introducing 14 new application control signatures for cloud-native services like AWS Lambda and Azure Functions.
