Vote for NGSecureWeb for Web Servers
NGSecureWeb is the result of the fusion of two security technologies: Firewalls and IDSs, (Intrusion Detection Systems).
NGSecureWeb filters all traffic from client to the web-server, looking for well-known attacks to web-servers and to its third party applications. When NGSecureWeb detects a possible attack (acting as an Application IDS), it will refuse to forward it to the web server (acting as an Application Firewall).
