FortiWeb Cloud WAF-as-a-Service by Fortinet is a cloud-based web application firewall (WAF) solution that protects public cloud hosted web applications and APIs from OWASP Top 10 threats, zero-day threats, and application layer attacks. The service operates as a Software-as-a-Service (SaaS) model requiring no hardware or software installation and can be deployed across multiple cloud regions, including AWS, GCP, and Azure. It utilizes gateways to filter application traffic within the same region as the protected applications, addressing performance requirements and regulatory compliance while minimizing traffic costs. The solution employs AI-based machine learning algorithms for improved cybersecurity and reduced administrative overhead, and includes a setup wizard with predefined policies for rapid deployment.
