Quttera's Cloud-Based Web Application Firewall (WAF) filters all incoming traffic to your website or application. Provided as a part of the ThreatSign! Website Anti-Malware platform
Quttera's WAF blocks malicious visitors and requests like SQL injections, XSS, and other application-layer attacks as well as unknown (zero-day) threats.
A traditional firewall is application-agnostic. It filters traffic based on origin, protocol, and well-known patterns. Increasingly, though, attackers go after vulnerabilities in applications and content management systems. A conventional firewall won't recognize those threats. A WAF knows about application-specific attacks and stops them from getting through.
