Tenable Vulnerability Management API

Tenable Vulnerability Management (formerly Tenable.io) is a cloud-based vulnerability management platform with a REST API for programmatic access to scan management, asset inventory, vulnerability findings, web application scanning, and compliance reporting. The API enables agents to trigger scans, retrieve vulnerability data, manage assets and tags, query audit log events, and integrate findings into ticketing or SOAR systems. The pyTenable Python SDK wraps the REST API with convenience methods.

Secret Handling

API key + secret. Role-based access control. SOC2 Type II, ISO27001, FedRAMP. Vulnerability scan data is highly sensitive — strict need-to-know access. Tenable is an enterprise security vendor — security is core competency.

Best When

An agent needs to query, prioritize, or act on vulnerability findings in an enterprise environment already running Tenable scanners, particularly for network and host vulnerability management workflows.

Avoid When

Your organization doesn't have a Tenable subscription or needs lightweight, free vulnerability scanning — the pricing is enterprise-tier with no affordable self-serve option.

Use Cases

• Querying vulnerability findings across the asset inventory for automated remediation ticket creation
• Triggering on-demand scans against specific assets and retrieving results programmatically
• Pulling asset vulnerability scores for risk prioritization in security dashboards
• Exporting large vulnerability datasets for SIEM ingestion and trend analysis
• Automating compliance assessment reporting for PCI-DSS, CIS, and DISA STIG benchmarks

Not For

• Organizations without Tenable licensing — enterprise pricing with no public self-serve tier
• Agentless cloud posture management (use CSPM tools like Wiz for cloud-native coverage)
• Real-time endpoint detection and response (EDR) — Tenable is periodic scanning, not continuous monitoring
• Web application dynamic testing requiring active exploitation simulation

OpenAPI Spec ↗

Authentication

Methods: api_key

OAuth: No Scopes: Yes

API key authentication using X-ApiKeys header with format 'accessKey=ACCESS_KEY; secretKey=SECRET_KEY'. Two-key model: access key identifies the account, secret key signs requests. Keys generated per user in Tenable.io portal. No OAuth support. Role-based permissions control which API actions are available per user/key.

Pricing

Model: enterprise-license

Free tier: No

Requires CC: No

No public pricing or self-serve tier. All plans require sales engagement. The on-premises Nessus Professional edition has public pricing (~$4,290/year) but the cloud API (Tenable.io/TVM) requires enterprise contracts.

Known Gotchas

⚠ Bulk vulnerability exports use an async job pattern — agents must poll export job status before retrieving results (not a synchronous response)
⚠ Two-key auth (accessKey + secretKey) in a single header is non-standard and easy to misformat
⚠ Asset UUIDs change when an asset's identifying attributes change — long-lived agents must handle asset ID transitions
⚠ Scan results are only available after scan completion — agents must monitor scan state (pending, running, completed, aborted)
⚠ Rate limits (200 req/min) can be exhausted quickly by agents processing large asset inventories
⚠ Web application scanning and host scanning are separate API subsystems with different endpoint patterns
⚠ Vulnerability severity uses Tenable's VPR (Vulnerability Priority Rating) in addition to CVSS — agents must understand both scoring systems

Alternatives

{'id': 'qualys-api', 'reason': 'Competing enterprise vulnerability management platform with similar REST API capabilities — choose based on existing deployment'} {'id': 'snyk-api', 'reason': 'Better for developer-centric dependency and code vulnerability management rather than network/host scanning'} {'id': 'crowdstrike-api', 'reason': 'If already on CrowdStrike Falcon, Spotlight module provides vulnerability data with endpoint agent correlation'}
