The Cybersecurity Evaluation Tool (CSET) is a free software application designed to help organizations identify vulnerabilities in their enterprise and industrial control systems. The tool employs a hybrid approach that combines risk assessment methodologies with standards-based evaluation frameworks to analyze cybersecurity posture. CSET evaluates system configurations, security controls, and potential weaknesses across both IT and operational technology environments. The application provides structured assessments that generate recommendations for improving cybersecurity defenses. Users can conduct evaluations of their cyber systems through guided questionnaires and assessment modules that cover various security domains. CSET operates on Windows-based systems and supports both standalone desktop installations and client-server deployment architectures. The tool includes local installers for individual use as well as enterprise deployment binaries for larger organizational implementations. The software is distributed under open source licenses (MIT License and Apache License 2.0), making it freely available for organizations to download and use without licensing costs.
