No One Architecture Fits All: A Cross-Environment Evaluation of Hierarchical Red Team Agents
The study compared two red team architectures—RL+RL and LLM+LLM—across different cyber environments (CAGE-4 and Cyberwheel at 100/1010 hosts). Results showed that RL+RL performed better in compact networks like CAGE-4, while LLM+LLM excelled in larger networks. This indicates that no single architecture is universally superior; effectiveness depends on the specific network structure and environment.
