Introduction to FWB_KVM-v600-build1235-FORTINET.out.kvm.zip

This virtualization package delivers FortiWeb OS 6.0.0 for KVM-based environments, specifically optimized for cloud-native web application firewall (WAF) deployments. Released on April 25, 2025, build 1235 introduces hardware-assisted TLS 1.3 quantum resistance and automated API threat modeling aligned with OWASP Top 10 2024 standards.

The software targets enterprise DevOps teams requiring:

  • Unified security policies across hybrid cloud infrastructures
  • PCI-DSS 4.0 compliance for payment processing systems
  • Containerized workload protection in OpenShift/Kubernetes clusters

Compatible with FortiWeb 4000V series virtual appliances and third-party KVM hypervisors.
