Reviews for Web Application Firewall (WAF) Software

What is web application firewall (WAF) and security software?

The WAF market is driven by a customer's need to protect internal and public web applications when they are deployed locally (on-premises) or remotely (hosted, cloud or as a service). WAFs protect web applications against a variety of attacks, including notably injection attacks and application layer denial of service (DoS). They should not only provide signature-based protection, but should also support positive security models. WAFs are deployed in front of web servers to protect web applications against external and internal attacks, to monitor and control access to web applications, and to collect access logs for compliance/auditing and analytics. WAFs are most often deployed in-line, as a reverse proxy, because historically it was the only way to perform some in-depth inspections.
