TenableOne is a cyber exposure management platform that provides a centralized view of an organization's attack surface by consolidating data from IT assets, cloud environments, web applications, and identity systems. The platform discovers and inventories assets, including those on the internet and in operational technology (OT) environments, to identify vulnerabilities, misconfigurations, and other security weaknesses. It analyzes and visualizes potential attack paths, assigns criticality ratings to assets, and uses a risk-based model to prioritize remediation efforts. TenableOne quantifies cyber exposure through scoring and benchmarking, offers remediation guidance, and allows organizations to track mitigation progress through analytics, dashboards, and reporting.
