CyberArena: Benchmarking AI Agents in Live Symmetric Attack-and-Defense Combat

To address this gap, we present CyberArena, a dynamic, symmetric adversarial benchmark built around multi-round attack-and-defense combat.

Key points

  • AI agents are demonstrating increasingly strong offensive and defensive cybersecurity capabilities in the real world.
  • Current benchmarks mostly evaluate agents in isolation against static targets.
  • Furthermore, because pairwise contests are notoriously hard to quantify, we introduce a dynamical model that maps match dynamics into unified, multidimensional scores across offensive, defensive, and domain-specific capabilities.
  • Evaluating 12 frontier LLM agents across 40 challenges in 466 matches, CyberArena separates model capabilities where single-agent baselines hit a ceiling.
