FortiWeb is Fortinet's web application firewall, available as a hardware appliance, virtual machine, container, or SaaS (FortiWeb Cloud). It uses two layers of machine learning to model normal application behaviour and flag anomalies, which reduces false positives without heavy manual tuning.

HOW IT WORKS
Beyond core WAF it covers API protection and bot mitigation, and it plugs into the wider Fortinet Security Fabric, so organisations already running FortiGate firewalls can manage web protection within the same ecosystem and share threat intelligence.
FortiWeb is enterprise-oriented, with appliance and VM options priced by quote and a cloud tier with usage-based pricing. It is a strong fit for Fortinet-standardised networks; small single sites are better served by a self-serve cloud WAF.
Category context: Edge and cloud WAF platforms for larger sites and APIs, with managed rules, bot defence, and DDoS at global scale. Usually custom-priced.
WHAT IT DOES
- WAF as hardware appliance, VM, container, or cloud (FortiWeb Cloud)
- Machine-learning anomaly detection to cut false positives
- API protection and bot mitigation
- Integration with the Fortinet Security Fabric
BEST FOR
- Enterprises already using Fortinet / FortiGate
- Organisations wanting appliance, VM, or cloud WAF options
- Teams valuing ML-based anomaly detection and API protection

What is Fortinet FortiWeb?
FortiWeb is Fortinet's web application firewall, available as a hardware appliance, virtual machine, container, or SaaS (FortiWeb Cloud). It uses machine-learning anomaly detection to reduce false positives, adds API protection and bot mitigation, and integrates with the Fortinet Security Fabric.
How much does FortiWeb cost?
FortiWeb appliances and virtual machines are enterprise-priced by custom quote based on throughput and model, while FortiWeb Cloud offers usage-based tiers. It is most cost-effective for organisations already standardised on Fortinet products.
Is FortiWeb worth it if we already use FortiGate?
For Fortinet-standardised networks, FortiWeb is a natural addition: it shares threat intelligence and management with the Security Fabric, so FortiGate customers can extend consistent policy to the web-application layer. If you are not in the Fortinet ecosystem, weigh it against F5, Imperva, or a cloud-native WAF.
