FAQs
If you run internet-facing applications or APIs, yes. A WAF is a Layer 7 security control that inspects HTTP/HTTPS traffic and blocks attacks that network firewalls aren't designed to stop, such as injection, cross-site scripting (XSS), bots, and API abuse. WAFs also enable virtual patching, which shields known vulnerabilities until code fixes ship. F5 WAF solutions deliver this protection across on-premises, hybrid multicloud, and Kubernetes environments.
Look for protection that goes beyond the OWASP Top 10 to include API security, bot mitigation, and application-layer DDoS /DoS defense, as well as deployment options that match where your applications run and that offers consistent security policies across every environment. Independent testing helps validate effectiveness: F5 earned[JK1.1][JS1.2] a score of 97.23% from SecureIQLab for OWASP WAF assessment, and a perfect score of 100% in the Bot attack, Layer 7 DoS & DDoS, Security Resiliency, and AI-assisted Bot Attack assessments.
F5’s portfolio of WAF products protect applications, APIs, and AI-powered services from modern threats, including the OWASP Top 10, bots and automated attacks, API abuse, account takeover attempts, and application-layer (Layer 7) denial-of-service (DoS) attacks. This coverage helps security teams reduce risk and maintain consistent protection wherever their applications are deployed.
F5 WAF solutions deploy across on-premises, hybrid multicloud, and containerized environments, with support for traditional, cloud-native, and SaaS-delivered security models. This flexibility lets security teams apply consistent protection for applications, APIs, and AI-powered services wherever they run—reducing risk and maintaining control across modern application architectures.
