Visibility
Unmatched OT/IT/IoT visibility
Tenable’s patented hybrid discovery combines active and passive scanning to deliver full visibility of your attack surface and proactively close risk exposure.
-
Active querying: Get in-depth vulnerability insights and reduce false positives by safely querying OT systems using native protocols to check for misconfigurations, outdated firmware, and more.
-
Passive monitoring: Continuously analyze network traffic with passive monitoring capabilities for real-time updates on new devices, applications, and vulnerabilities.
This unique combination helps uncover hidden assets and vulnerabilities that passive monitoring often misses, including IoT devices using application-based scanning capabilities to discover asset details and communication paths.
“Tenable’s track record in high-risk environments was a big factor, especially active query. Everyone else can do passive, but we weren’t looking at passive, because otherwise, we could continue with the solution we had in place.”
North American railroad company
Exposure
Exposure management from identity to on-prem to OT
The Tenable One Exposure Management Platform provides unified visibility across cloud, identities, on-prem, and OT/IoT systems in a single solution. It offers granular vulnerability intelligence, tracks vulnerability history, and enables risk remediation tracking with a risk-based approach.
An extensive library of dashboards and reports help facilitate communication with stakeholders such as senior leaders, IT and security teams, auditors, insurance providers, and board members.
“When it comes to operational technology …that's where Tenable wins.”
Vulnerability management architect, German manufacturing company
