Ruge by Rugged Tooling is a versatile IP traffic generator and cybersecurity tool designed for load testing, security assessment, and network emulation. It can generate, modify, and monitor high-volume IP traffic at rates ranging from 1G to 100G, supporting various network technologies including 2G, 3G, 4G, 5G, pure IP networks, and Wi-Fi. Ruge simulates realistic attack scenarios by generating traffic from millions of sources, allowing users to test their systems against large-scale cyber threats without causing actual damage. It can combine simulated attack traffic with typical network load to provide a realistic representation of cyber attacks in a live environment. Ruge is capable of emulating multiple users simultaneously, such as shoppers, people signing in to a service, or making voice calls. The tool supports both stateless and stateful traffic generation with full bit-level control, enabling users to create precise traffic scenarios. It is particularly useful for DDoS attack emulation, negative testing, system capacity verification, and security robustness testing. Ruge can be used for testing Internet of Things (IoT) and Industrial Internet of Things (IIoT) systems, as well as providing load generation capabilities for professional cyber ranges. Depending on testing needs, Ruge is available as a light, portable device with 1 Gbps line rate, or a U-rack mountable powerful device with up to 25 Gbps line rate.
