Dispel and Tenable Combine OT Asset Data with Zero-Trust Access Controls
The new integration syncs real-time asset intelligence from Tenable One OT Exposure directly into Dispel’s remote access decisions to align security and operations.
Key points
- Dispel integrates Tenable One OT Exposure data into its Zero Trust Engine for automated policy enforcement.
- The partnership aims to resolve conflicting risk views between security, operations, and governance teams.
- Session forensics correlate with device risk profiles to produce single-color access approvals.
Dispel has announced a technical integration with exposure management firm Tenable Holdings. This partnership combines Tenable One OT Exposure capabilities with the Dispel Zero Trust Engine, according to Industrial Cyber. The move brings real-time operational technology and Internet of Things asset intelligence directly into remote access decision-making processes for industrial environments.
The integration automatically syncs Tenable’s visibility into asset characteristics, configurations, behaviors, and vulnerability profiles into Dispel’s platform. This ensures that access policies reflect the current state of the environment without requiring manual reconciliation. The goal is to provide a unified foundation for secure access decisions across plants, sites, and vendor connections.
Bridging Operational and Security Perspectives
Industrial security programs often face conflicting priorities among different organizational teams. Security groups typically demand tight controls, while operations teams prioritize production continuity and uptime. Governance, risk, and compliance departments require proof that controls function effectively. This integration addresses the gap that arises when these groups work from separate risk assessments.
Ben Burke, president and COO of Dispel, stated that both security and operations have legitimate needs. He noted that these teams often view the same risk from different angles. The integration places both perspectives in front of the decision-maker at the moment access is requested.
Impact on Remote Access Workflows
Legacy remote access methods, such as virtual private networks and jump hosts, often introduce delays. Fragmented tools can complicate manual vendor workflows, slowing down original equipment manufacturers, contractors, and operators. These inefficiencies create operational drag across multiple sites and incident response scenarios.
Dispel’s Session Forensics evaluates every session from login to disconnect. It tracks authentication strength and behavioral baselines to identify shared credentials and vendor sprawl patterns. Standard access logs often miss these indicators. The system correlates session data with Tenable’s device risk scores to generate a single traffic-light status for approval.
A green user connecting to a green device receives a standard approval. This streamlined process aims to accelerate onboarding and approvals when speed is critical. The combined scores from session behavior and device vulnerability resolve into clear green, yellow, or red indicators for operators.
What should you do?
Security leaders should review their current remote access approval workflows for manual reconciliation steps. Evaluate whether existing tools provide unified visibility into both user behavior and asset vulnerability. Monitor for integrations that automate policy updates based on real-time asset intelligence. Verify that session forensics capabilities can detect shared credential usage among external vendors.
What to do and how to stay safe: Dispel
- Audit current remote access policies to identify reliance on manual risk reconciliation between security and operations teams.
- Verify that your asset management tools provide real-time visibility into device configuration and vulnerability profiles.
- Review session logs for patterns indicating shared credentials or unauthorized vendor access sprawl.
- Ensure access decisions incorporate both user authentication strength and target device risk status before granting permissions.
