Is there a CloudGen firewall that also have WAF features?

In Summary :

Hi, please excuse me for any technical mistake, I am a novice in terms of security.We are hosting an infrastructure on the cloud that contains multiple machines and a web application. Is there any CloudGen firewall that also could monitor and block threats coming on the web application? We also would like to have the less expensive one that covers everything we need.This should contain those features:SQL injection protectionCross site scripting protectionCommon Web Attacks Protection such as command injection, HTTP request smuggling, HTTP response splitting, and remote file inclusion attackProtection against HTTP protocol violationsProtection against HTTP protocol anomalies such as missing host user-agent and accept headersPrevention against bots, crawlers, and scannersDetection of common application misconfigurations (for example, Apache, IIS, and so on.)Also OWASP protection.Thank you [...]
