AgentCyberRange tests frontier AI systems in realistic cyber ranges

AgentCyberRange is a benchmark for evaluating frontier AI systems in realistic cybersecurity environments. It tests agents across operational phases and emphasizes complex, multi-step tasks rather than isolated question answering. The results provide a more grounded view of autonomous cyber capability and expose where current agents still fail, which is important for both defensive deployment decisions and assessments of misuse risk.

Key details: Submitted June 2026, Uses realistic cybersecurity ranges, Tests complex multi-step agent behavior, Targets frontier AI systems.
