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

Standard cybersecurity benchmarks largely rely on static Capture-The-Flag challenges that fail to reflect dynamic conflict. CyberArena introduces a live symmetric evaluation environment where AI agents act as red and blue teams against each other in real time. Rather than measuring single-step puzzle solving, the platform evaluates an agent's ability to discover vulnerabilities, apply runtime mitigation, and adapt tactical behaviors under active adversarial pressure.
