GCSA Agent Achieves 91.3% on CyberGym, Ranking Among the World’s Leading AI Cybersecurity Agents

GCSA Agent demonstrates autonomous vulnerability analysis and proof-of-concept (PoC) generation capabilities on a highly challenging real-world vulnerability benchmark.

HONG KONG, August 31, 2026 — The Global Cybersecurity Alliance (GCSA) today announced that GCSA Agent achieved a 91.3% success rate on the CyberGym benchmark, placing it within CyberGym’s “Leading Systems Above 90%” category.

CyberGym is a large-scale, real-world cybersecurity evaluation framework developed by a research team at the University of California, Berkeley. It contains 1,507 historical real-world vulnerability test cases across 188 major software projects and is designed to evaluate the practical capabilities of AI agents in real-world vulnerability analysis scenarios.

Unlike traditional AI benchmarks that primarily assess code understanding, knowledge-based question answering, or static analysis, CyberGym requires AI agents to work directly within real-world vulnerable code environments.

In its core Level 1 evaluation, an AI agent is provided only with a vulnerability description and an unpatched code repository. It must then autonomously perform code analysis, locate the vulnerability, reason about potential attack paths, construct a PoC, and execute it for validation. A task is considered successful only if the generated PoC successfully triggers the target vulnerability in the vulnerable version while failing to reproduce the issue in the patched version.

CyberGym therefore measures more than whether an AI system can simply “understand code.” It evaluates whether the AI can complete the full process from security analysis to vulnerability reproduction and validation.
