DeRISK by DeNexus is an evidence-based, data-driven platform that translates OT cyber risk exposures and vulnerabilities into business metrics, including the financial impact of potential cyber events. It quantifies cyber risk using inside-out and outside-in risk data with sector-specific modeling, enabling executives to make informed decisions about cyber risk management and governance. DeRISK offers dynamic risk aggregation, site and portfolio level risk analysis, and dynamic mapping of potential attack paths and loss events. It quantifies risks with expected loss metrics, top drivers of risk, types of loss, and facilities sorted by risk contribution. DeRISK combines internal OT telemetry, including devices, vulnerabilities, and controls, with external threat intelligence to identify likely attack paths and evaluate the financial impact of potential cyber incidents. It transforms cybersecurity telemetry into financial risk metrics for executive reports, bridging the gap between the control room and the boardroom. By aggregating security signals from various tools and mapping them to cybersecurity standards, DeRISK identifies the sources of cyber risk and how it evolves, enabling better mitigation of threats. Cyber risk quantified in monetary terms guides executives on investment decisions and tracks progress in risk reduction, demonstrating effective governance. It includes pre-configured risk mitigation strategies and runs billions of simulation runs weekly per site.
