Traffic IQ Professional is a Windows-based network security testing and auditing tool designed to assess, audit, and improve the detection and response capabilities of network-based intrusion detection and prevention systems (IDS/IPS), application layer firewalls, routers, and switches. The tool operates by replaying recorded traffic files against target devices to evaluate how those devices respond — whether they allow or block the traffic. It supports testing of packet-filtering devices without requiring proxy-based configurations. Key use cases include: - Regulatory compliance validation and auditing - Rule-based ingress and egress testing - IDS/IPS recognition and response testing - Security signature development and fine-tuning - Change control procedure verification - Advanced penetration testing - Application protocol and threat traffic scanning Traffic IQ Professional includes a built-in traffic library containing information on over 21,000 application threats and exploits. Users can organize traffic files into groups, create scan lists using a point-and-click interface, and generate reports that show which traffic was allowed or blocked. The tool is designed for use without scripting or development knowledge, running on standard Windows hardware from laptops to dedicated appliances. An optional add-on allows users to apply security rules from the Traffic IQ Library to existing security devices to extend their threat detection capabilities.
