I previously used Barracuda Web Application Firewall. I hope that Azure Web Application Firewall will look at other products and replicate some of their functionality. Azure WAF is doing great because it is designed to host web applications in Azure. However, it can be improved with other services. Barracuda is the most advanced firewall in the industry, so Azure WAF could pick some of its features and replicate them into its own application firewall. Barracuda WAF was deployed in parallel to the traffic. Azure WAF should not be deployed in the middle of the traffic. It should support both public and private points of presence. Additionally, like Barracuda, Azure WAF should have an inspection engine that covers not just Microsoft products, but also products from other manufacturers. This would be a great addition to the product and would increase its security functionality.
