​Introduction to FWB_XENOPEN-v600-build1239-FORTINET.out​

This software package provides the latest security updates and feature enhancements for FortiWeb virtual appliances running on Citrix XenServer hypervisors. Released under Fortinet’s Q3 2025 security advisory cycle, Build 1239 addresses critical vulnerabilities while optimizing web application firewall (WAF) performance in virtualized environments.

Designed for XenServer 8.2 and newer, this OVA template strengthens protection for cloud-native applications through improved API security and TLS 1.3 post-quantum cryptography support. IT teams managing hybrid cloud infrastructures or DevOps environments should prioritize deployment to mitigate OWASP Top 10 2025 risks.
