What is web application firewall?
Web Application Firewall (WAF) Software is software that centralizes web application firewall — the records, tasks, and history that would otherwise be scattered — into one place every stakeholder can access.
A web application firewall tool collects information from multiple inputs, keeps it organized, and automates the busywork around it — the routing, the reminders, the updates — so people focus on the decisions, not the admin.
The result is a single, real-time view of your web application firewall. Azure WAF, Barracuda WAF, and F5 Advanced WAF take different approaches — some focus on simplicity, others on breadth — which is exactly what the comparison below is built to clarify.
