Compare Tenable One OT Exposure vs. VigiaOT

Tenable One OT Exposure is a cyber-physical systems security platform built to help organizations protect operational technology, industrial control systems, and mission-critical infrastructure. It gives security teams a unified way to monitor OT environments, discover assets, prioritize vulnerabilities, detect threats, protect networks, and support compliance programs. The platform is designed for environments where uptime and operational continuity are essential, helping teams improve security without disrupting production or innovation. Tenable One OT Exposure can help identify unmanaged, unknown, or shadow OT assets and provide visibility across complex multi-site or global operations. Its exposure intelligence helps teams understand which vulnerabilities and changes matter most so they can focus remediation on the highest-risk issues. The platform also supports security teams by reducing fragmented alerts and improving communication of OT risk to business and technical stakeholders. As part of Tenable One, it extends exposure management across IT, cloud, identity, and OT attack surfaces. Organizations can use Tenable One OT Exposure to strengthen detection, improve asset awareness, simplify compliance, and accelerate risk reduction across industrial environments. It is built for teams that need practical OT security visibility and prioritized action across rapidly expanding cyber-physical ecosystems.

VigiaOT serves as a solution for the identification of operational technology (OT) assets and the management of vulnerabilities within industrial facilities. The Solo editions are designed to operate on technicians' laptops running Windows or macOS, employing read-only active scans to detect industrial devices while gathering information such as vendor names, models, firmware versions, protocols, and open ports. After identifying the devices, technicians can assess their findings, keep a detailed local inventory, categorize network exposure, and export these inventory details as needed. The Solo Analytics feature enhances this process by correlating the data with sources like the National Vulnerability Database (NVD), ENISA’s EU Vulnerability Database (EUVD), and the CISA Known Exploited Vulnerabilities (KEV) list, while also prioritizing the findings and providing a structured workflow for reviewing vulnerabilities. For larger deployments across multiple workstations, Site Analytics compiles inventories on an on-premises VIGIA-IOTBOX appliance, and optional modules can facilitate passive monitoring for devices that connect to IT networks, alongside AI-driven analysis of manufacturer advisories. This product is specifically designed for industrial operations and security teams focused on the protection of OT and IT networks within plant environments, ensuring a comprehensive approach to asset management and security. By integrating both active and passive monitoring capabilities, VigiaOT enhances the overall security framework of industrial operations.
