FortiWeb: Web Application Firewall and API Protection

Machine Learning Enabled Protection for Business-Critical Applications

Case Study: Fortinet Protected by Its Own WAF-as-a-Service
web product icon web application security

FortiWeb Overview

FortiWeb, Fortinet’s Web Application Firewall, protects your business-critical web applications from attacks that target known and unknown vulnerabilities.

The attack surface of your web applications evolves rapidly, changing every time you deploy new features, update existing ones, or expose new web APIs. You need a solution that can keep up.  FortiWeb is that solution.

FortiWeb takes a comprehensive approach to protecting Web applications, including IP reputation, DDoS protection, protocol validation, application attack signatures, bot mitigation, and more to defend your application against a wide range of threats, including the OWASP Top 10.  But we don’t stop there.

FortiWeb machine learning automatically builds and maintains a model of normal user behavior and uses that model to identify benign and malicious application traffic without the time-consuming manual application-learning required by most WAFs.

FortiWeb Product Details

FortiWeb WAFs provide advanced features that defend your web applications and APIs from known and zero-day threats. Using an advanced multi-layered approach, FortiWeb protects against the OWASP Top 10 and more. FortiWeb ML customizes the protection of each application, providing robust protection without requiring the time-consuming manual tuning required by other solutions. With ML, FortiWeb identifies anomalous behavior and, more importantly, distinguishes between malicious and benign anomalies. The solution also features robust bot mitigation capabilities, allowing benign bots to connect (e.g. search engines) while blocking malicious bot activity.

FortiWeb offers deployment options that can protect business applications, no matter where the application is hosted. Options include hardware appliances, virtual machines, and containers that can be deployed in the data center, in cloud environments, or in the cloud-native SaaS solution, FortiWeb Cloud WAF as a Service.


"The cloud will continue to become more and more important. It makes sense to use a common Fortinet platform for both the Microsoft and Amazon cloud service platforms: doing so gives us the protection we require and economies of scale as we don’t have to learn and maintain two different systems."
