WAFs for Customer-Facing Application Risk

Customer-facing applications expose risks that network firewalls alone do not address, especially when attacks target application logic, APIs, credentials, or encrypted traffic. The article explains how web application firewalls inspect Layer 7 traffic, support OWASP Top 10 protection, mitigate bot activity, enable virtual patching, and extend coverage to APIs and cloud-hosted applications. It also highlights operational considerations such as false positives, ML-based anomaly detection, deployment models, compliance, and integration with broader security controls. Technology leaders should treat WAFs as part of an application-layer security architecture, not as a one-time compliance control.
