Tenable OT Security
OT visibility and vulnerability management, unified with IT
Tenable OT Security (Tenable.ot) extends the Tenable vulnerability-management programme into industrial control systems. Born from the 2019 Indegy acquisition, it pairs hybrid passive plus ICS-aware active discovery with the strongest vulnerability-management lineage on the market. The right choice when Tenable already runs your IT vulnerability programme and OT is being added.

What Tenable OT is
Tenable.ot was born from the 2019 acquisition of Indegy, an Israeli ICS visibility startup. Tenable then folded the platform into its broader Tenable One exposure-management ecosystem, alongside Tenable.io (cloud VM), Tenable.sc (on-prem VM) and Tenable Identity Exposure. The result is the most credible unified IT and OT vulnerability story in the market.
The platform's hybrid discovery is its defining strength. Passive monitoring identifies controllers, HMIs and historians from ICS-protocol traffic. ICS-aware active queries (carefully engineered to be safe) reach assets that passive monitoring cannot see, particularly in lightly trafficked or air-gapped segments. The combination produces a more complete asset inventory than pure-passive platforms.
Where Tenable.ot wins decisively is unified vulnerability management. A single risk-scoring methodology, one analyst workflow and one set of compliance reports cover both IT and OT, the operational simplification when Tenable already runs your IT VM programme is substantial. The right answer is operational, not best-of-breed ICS detection alone.
Unified IT + OT
vulnerability management
One risk methodology, one analyst workflow, one set of dashboards across IT and OT. The operational simplification when Tenable already runs your IT VM programme.
- Indegy heritage with Tenable VM lineage
- Hybrid passive + ICS-aware active discovery
- Asset-level CVE mapping (best-in-class)
- Configuration drift detection
- Unified with Tenable.io and Tenable.sc
- Tenable One exposure-management integration
- ICS-aware queries safe in production
- IEC 62443, NESA, ADHICS compliance reporting
Why it wins
What makes Tenable OT Security the unified-VM choice
The strengths that show up most often where unified IT and OT vulnerability programmes matter more than best-of-breed ICS detection alone.
Unified
IT + OT vulnerability programme on one risk methodology and analyst workflow
Hybrid
Passive + ICS-aware active discovery, most complete asset inventory
Tenable One
Plugs into the broader exposure-management ecosystem (.io, .sc, Identity)
Best-in-class OT vulnerability management
Tenable.ot inherits Tenable's market-leading vulnerability-management methodology, the most mature CVE prioritisation, asset risk scoring and remediation workflow in the industry, applied to industrial assets.
Unified IT and OT VM
Tenable.ot, Tenable.io and Tenable.sc share data, scoring and dashboards. One risk methodology, one analyst workflow, one set of reports for both IT and OT. Substantial operational simplification.
Hybrid passive + active discovery
Passive monitoring catches everything on the wire. ICS-aware active queries reach assets that passive cannot see (air-gapped segments, low-talk devices). The combination is the most complete inventory of any platform.
Configuration drift detection
Tracks controller-program changes, OS configuration drift, firmware versions and ICS-specific settings. Catches the slow, low-noise compromises that pure-CVE scanning misses.
Tenable One ecosystem
Plugs into Tenable One for unified exposure management across cloud workloads, identities, web apps and OT. The platform of choice when exposure management is the broader programme.
ICS-aware safe active queries
Active queries are deliberately engineered to be safe in ICS environments, allowing deeper interrogation of controllers where the plant culture permits. Always opt-in and always tested in pilot.
Who should put Tenable OT Security on the shortlist
UAE customers already running Tenable.io or Tenable.sc for IT vulnerability management
Organisations consolidating IT and OT VM into one programme with one risk methodology
Plants where ICS-aware active discovery delivers more complete inventory than pure passive
Industrial estates where vulnerability management drives the risk programme, not just detection
Mid to large manufacturing, utilities and process industries with mature IT VM operations
Programmes feeding Tenable One exposure-management dashboards to executives
Compliance-led customers needing unified IT and OT vulnerability evidence for NESA and ADHICS
Teams who value operational simplification over best-of-breed ICS detection alone

Choosing a product
Simplified positioning, which Tenable product fits
Tenable.ot is the OT core. Pair it with Tenable.io (cloud VM) or Tenable.sc (on-prem VM) for unified IT + OT, layer Tenable One for full exposure management.
The strategic view
How the products relate
Tenable.ot alone proves OT VM value. Pairing with Tenable.io or .sc unifies IT and OT. Tenable One adds exposure-management scale.

Fully managed, co-managed or assessment-only.
Frequently asked
Tenable OT Security questions we hear from UAE buyers
When does Tenable OT Security beat Nozomi or Claroty?
When Tenable already owns the IT vulnerability-management programme. Tenable.ot extends that programme into OT with one risk methodology, one workflow and unified dashboards. The case is operational simplification across IT and OT, not best-of-breed ICS detection alone, Nozomi and Claroty remain the depth leaders for that.
