Why This Update Is Essential
With SMBs experiencing 58% more web application attacks in 2025 (FortiGuard Labs), build 0391 provides critical protections for:
- Retail businesses processing PCI-compliant transactions
- SaaS startups securing customer-facing APIs
- Healthcare clinics managing PHI through web portals
Administrators using FortiWeb 100D appliances should prioritize this update if running firmware versions prior to v7.0.0, particularly due to CVE-2024-59122’s 9.3 CVSS score. Conduct staged deployments using FortiWeb’s built-in traffic mirroring tools before full implementation.
Note: Unauthorized distribution violates Fortinet’s End-User License Agreement. Always verify cryptographic signatures before installation.
