Overview
 The FortiWeb 400F is a high-performance Web Application Firewall (WAF) appliance designed to protect web applications and APIs from the full spectrum of attacks — from known vulnerabilities to zero-day exploits. It is suitable for data centres, enterprise applications, service providers and cloud-hybrid deployments. The appliance form-factor provides a rack-mountable 1U solution with multiple gigabit ports and high throughput performance. This makes it a strong choice for organisations seeking robust application-layer security combined with the breadth of features required for modern web and API-centric infrastructures.
 
Key Features
- Multi-layer web application protection: defends against OWASP Top 10 web application threats, unknown exploits and zero-day attacks.
- Machine-learning-based detection: models each application’s behaviour and helps reduce false positives while detecting anomalous behaviour.
- API protection: guards mobile-apps, public APIs and microservices with schema verification (JSON/XML), API gateway support and CI/CD pipeline integration.
- Advanced bot mitigation: differentiates legitimate bots from malicious ones, protects web assets without undue friction to legitimate users.
- High performance hardware platform: dedicated gigabit interfaces (4 × GE-RJ45 + 4 × GE-SFP) and throughput of about 500 Mbps in the 400F model.
- Flexible deployment modes: reverse proxy, inline transparent, true transparent proxy, offline sniffing and WCCP modes.
- Application delivery capabilities: layer-7 load balancing, URL rewriting, content routing, HTTPS/SSL off-loading, HTTP compression and caching.
- Authentication & access control: supports active/passive authentication, SSO site-publishing, LDAP, RADIUS, SSL client certificates, 2-factor authentication and browser-based enforcement.
- Management, monitoring & reporting: includes web-UI, CLI, REST API, FortiView dashboard, SNMP/Syslog/email logging, geo-IP analytics and OWASP categorisation.
- High availability and scalability: supports Active/Passive or Active/Active clustering, administrative domains (up to 32 in this model) and centralised management of multiple appliances.
- IPv6 and HTTP/2 support, SSL/TLS off-loading and full integration into the security fabric of the manufacturer for broader threat intelligence and security orchestration.
