Overview

Defend Web Applications and APIs Against OWASP Top 10 Threats, Sophisticated Bots, and DDoS Attacks

FortiWeb features anomaly detection, API discovery and protection, bot mitigation, and client-side security. It leverages AI for detection of zero-day exploits, advanced threat analytics, and a built-in SOC agent. This way, FortiWeb reduces administrative overhead and TCO for local, hybrid, and cloud deployments. It also enables right-sizing cloud services and spending, as part of the FortiFlex program.

Web Application Security

Detect and block emerging threats including AI-generated zero-day attacks that target applications—while securing legitimate users. FortiWeb’s dual-layer machine learning approach eliminates the excessive management overhead that traditional application learning requires. Applying machine learning to model each application, FortiWeb reduces administrative overhead by identifying malicious patterns, minimizing false positives, and prioritizing remediation contextually.

Bot Defense

Stop malicious bot activity without blocking bots that support legitimate business needs, such as search engines or health and performance monitoring tools. Reduce reliance on outdated techniques that degrade the user experience and leverage advanced techniques such as bot deception, biometric detection, and machine learning to accurately identify and manage bot traffic. FortiWeb bot protection provides the visibility and control you need without slowing down users with unnecessary CAPTCHAs or challenges.

API Discovery and Protection

Protect the APIs that enable business-to-business communications and support mobile applications. FortiWeb API discovery and protection uses machine learning algorithms to automatically discover APIs by continuously evaluating application traffic. FortiWeb delivers out-of-the-box policies with an automatically generated positive security model policy for each schema specification (OpenAPI, XML, JSON), to thwart API exploits. It protects APIs and seamlessly integrates API security into the CI/CD pipeline.

Client-side Protection

FortiWeb addresses a critical PCI DSS requirement to monitor scripts running on payment pages. Client-side protection extends FortiWeb’s capabilities to the browser environment, addressing modern threats that arise after content is delivered to the client. It’s a policy-based feature that detects and mitigates unauthorized activity, such as third-party script injections, DOM manipulation, and form hijacking, within the user’s browser. This functionality is essential for defending against advanced client-side attacks that evade traditional request/response inspection.

FortiWeb Cloud WAF-as-a-Service is a SaaS cloud-based web application firewall (WAF) that protects public cloud hosted web applications from the OWASP Top 10, zero day threats and other application layer attacks. 

Requiring no hardware or software, FortiWeb Cloud WAF as a Service employs gateways running in most AWS regions to scrub your application traffic within the same region your applications reside.  Scrubbing traffic in region addresses performance and regulatory concerns and keeping traffic cost to minimum.

With a built in simple setup wizard and predefined policies, FortiWeb Cloud delivers the security you need within minutes, removing the usual complexity required when setting up a WAF. More advanced users can easily enable additional security modules if needed, free of charge.
