Tenable

About Tenable

Tenable provides an exposure management platform that unifies security visibility, insight, and action across an organization's attack surface. The platform brings together native signals, exposure intelligence, and third-party data to map infrastructure, cloud, identity, OT, third-party applications, and AI. It uses agentic orchestration to coordinate remediation across teams and AI agents. Tenable states it serves more than 40,000 customers worldwide. The company was founded in 2002.

Products

Tenable One: Unifies security visibility, insight, and action across the attack surface.
Tenable Hexa AI: Acts as an agentic engine built on Tenable's Exposure Data Fabric to prioritize risk and coordinate action across teams and AI agents.
Vulnerability Management: Continuously discovers assets across the IT environment and prioritizes vulnerabilities by risk.
Cloud Exposure (CNAPP): Addresses cloud risk by closing misconfigurations, risky entitlements, and vulnerabilities across multi-cloud and hybrid environments.
Identity Exposure: Identifies weaknesses and overprivileged access in Active Directory and Entra ID.

Used for

Discovering and inventorying assets across IT, cloud, OT, web applications, and external attack surface.
Identifying vulnerabilities and misconfigurations across environments.
Discovering shadow AI, AI workloads, services, and externally exposed AI components.
Measuring and comparing exposure using risk scores and benchmarks.

Who it is for

Financial services organizations.
Healthcare organizations.

How to evaluate Vulnerability Management

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Tenable. It comes from our Vulnerability Management Platforms buyer guide.

25%

Asset Discovery & Coverage

Authenticated and unauthenticated scanning, agent + agentless options, coverage of cloud and ephemeral workloads, containers/Kubernetes, OT/IoT, identity, external attack surface, and unmanaged/shadow assets — plus how it avoids blind spots between scan windows

25%

Prioritization Quality

Beyond CVSS: exploit-prediction scoring (EPSS), known-exploited intelligence (CISA KEV), in-the-wild and ransomware association, exploit maturity, reachability/exploitability, and business asset criticality — the “which findings actually matter” engine and how transparent and tunable its scoring is

20%

Remediation & Workflow

Ticketing and ITSM integration (ServiceNow, Jira), patch-management hooks, remediation grouping by fix, SLA tracking, owner assignment, change-ticket automation, and closed-loop verification that a fix actually landed — not just that a ticket closed

15%

Exposure Context & Validation

Attack-path analysis and choke-point identification, unification of vuln + misconfiguration + identity findings, and validation that an exposure is genuinely reachable (control checks, exploitability confirmation) so the priority list reflects real risk, not theoretical severity

10%

Integration & Data Aggregation

Open API depth, ingestion of third-party scanner and CNAPP findings, de-duplication and normalization across tools, SIEM/SOAR and CMDB connectors, and how cleanly it fits an existing security stack rather than demanding rip-and-replace

Reporting & Program Metrics

Executive and board-ready risk reporting, trend lines on mean-time-to-remediate and risk burndown, SLA and compliance attestation (PCI, HIPAA, FedRAMP), and role-based views that hold owners accountable

Other Vulnerability Management Vendors

Maps an organization’s external attack surface, including subsidiaries and third-party dependencies, confirms which exposures are exploitable, and helps fix them.
