Fortinet FortiWeb 400F: Enterprise-Grade Web Application Firewall & API Security

Fortinet FortiWeb 400F is a next-generation web application firewall (WAF) appliance designed to shield your web assets, APIs, and microservices from evolving cyber threats. Engineered for high-traffic environments, the 400F blends cutting-edge machine learning with multilayer threat intelligence, bot mitigation, and API governance to deliver robust protection without compromising performance. It embodies Fortinet’s Security Fabric philosophy, enabling seamless integration with FortiGate, FortiManager, and FortiAnalyzer for centralized policy management, real-time analytics, and cohesive incident response. Whether you operate a data center, an e-commerce platform, or a large-scale SaaS environment, the FortiWeb 400F provides adaptive security, simplified administration, and measurable risk reduction across your entire web portfolio.

• Comprehensive, ML-driven protection for web apps and APIs. The FortiWeb 400F employs machine learning and behavior analytics to identify and block a wide spectrum of threats, including SQL injection, cross-site scripting, remote code execution patterns, and zero-day exploits. It continuously analyzes traffic patterns, payload characteristics, and contextual signals to distinguish malicious activity from legitimate user behavior. This reduces false positives while catching advanced attacks that traditional signature-based WAFs may miss, safeguarding sensitive data and critical business logic with confidence.
• Adaptive bot mitigation and refined user risk scoring. By combining device fingerprinting, behavioral baselining, and threat reputation data, FortiWeb 400F differentiates between human users and automated agents in real time. It can apply dynamic challenges, throttling, or outright blocks to bot traffic responsible for credential stuffing, automated scraping, and brute-force login attempts, all while preserving a smooth experience for genuine customers and partners. The result is stronger protection without turning away legitimate traffic or impacting conversion rates.
• Advanced API security and governance for modern architectures. The FortiWeb 400F includes API discovery, schema-aware input validation, and risk scoring to safeguard microservices, API gateways, and serverless endpoints. With policy enforcement that covers JSON/SOAP payloads and RESTful patterns, it prevents API abuse, data leakage, and business-logic manipulation. This ensures API ecosystems remain reliable, auditable, and compliant with industry regulations and internal data-handling policies.
• High-performance hardware with secure TLS/L7 inspection. Built to handle demanding workloads, the 400F leverages hardware acceleration to deliver fast, comprehensive TLS termination and inspection, malware scanning, and signature-based protections with low latency. Encrypting traffic becomes transparent to users while security remains deeply effective—critical for ecommerce, financial services, and any organization delivering secure web services at scale.
• Flexible deployment with scalable management across the Security Fabric. Suitable for data centers, edge deployments, and hybrid environments, the FortiWeb 400F supports scalable capacity, redundancy, and easy integration into Fortinet’s Security Fabric. Centralized management through FortiManager and FortiAnalyzer provides cohesive policy control, consolidated logging, and analytics, enabling rapid responses to incidents and consistent security posture across all protected assets.
