Fortinet FortiWeb 400F Web Application Firewall (FWB-400F)

Growing organizations running public-facing web applications need protection that operates at the application layer, not just the network perimeter. FortiWeb 400F (FWB-400F) is a dedicated hardware WAF appliance that inspects HTTP and HTTPS traffic, defends against OWASP Top 10 threats, API abuse, malicious bots, and volumetric application-layer attacks before requests reach your origin servers. Its eight-port configuration, with four copper GE RJ45 and four fiber SFP GbE ports, gives network teams flexibility in how they integrate it into existing infrastructure, whether bridging switch uplinks or connecting directly to fiber-attached segments.

Overview

FortiWeb 400F ships as a hardware appliance only; FortiWeb service subscriptions are purchased and licensed separately. The appliance provides the platform: threat detection engines, machine-learning models, and inspection capacity, while the service tiers (WAF, Advanced, and Enterprise bundles) are priced and renewed independently. This separation lets organizations right-size their service investment at renewal without replacing hardware.

The four SFP GbE ports are a distinguishing feature of the 400F compared to the 600F series, which carries two SFP ports. For environments that rely heavily on fiber connectivity or need to monitor multiple fiber-attached segments from a single appliance, the 400F’s higher fiber port count is a practical advantage without requiring media converters or additional switching. Storage is a 480GB SSD, used for log retention, traffic captures, and on-box threat intelligence caching. A single power supply is included; organizations that require power redundancy should evaluate the FortiWeb 600F.

FortiWeb inspects traffic destined for web applications and APIs, blocking SQL injection, cross-site scripting, file inclusion exploits, credential-stuffing bots, and application-layer DDoS. Machine-learning-based anomaly detection supplements signature coverage, reducing false positives without requiring administrators to manually tune every rule threshold.

Who it suits

FortiWeb 400F fits mid-market organizations and growing SMBs deploying a dedicated WAF appliance for the first time, or replacing a software-based solution with purpose-built hardware. It is particularly well matched to environments that need to connect to both copper-switched and fiber uplinks simultaneously, where the eight-port mix removes the need for additional media conversion hardware.

Teams running e-commerce storefronts, customer portals, corporate web applications, or externally exposed APIs on-premises will find the 400F’s inspection capacity appropriate for typical mid-range transaction volumes. Organizations that have already standardized on Fortinet, running FortiGate firewalls, FortiManager, or FortiAnalyzer, can extend the same management approach to web application protection through FortiWeb, using a familiar policy model and unified logging infrastructure.

If power redundancy or hardware SSL offload are hard requirements, for example in a 24/7 e-commerce environment where downtime has direct revenue impact, the FortiWeb 600F addresses those needs with dual AC power supplies and dedicated SSL hardware. The 400F is the right choice when fiber port density matters more than those features.
