Per-asset pricing decreases with volume
bundling InsightVM with InsightIDR or InsightAppSec yields 10-20% bundle savings; multi-year terms reduce annual cost
Hidden costs
Tenable annually increases prices each March
centralized cloud console requires the separate Tenable Vulnerability Management subscription; advanced features (EASM, IaC, web app scanning) gated to Expert tier
Implementation and training, professional services, Managed VM service if…
elected, additional Rapid7 modules (InsightAppSec for web app scanning sold separately), log ingestion for InsightIDR if bundled
↗ Deployment & integrations
3 dimensions
Deployment
Self-hosted scanner
one license = one scanner; agents available for distributed scanning; Tenable Vulnerability Management (separate product) provides cloud-hosted centralized management
Hybrid model
cloud-based Insight Platform + on-premises Security Console (control center) + distributed Scan Engines + Insight Agent for endpoints
Typical deployment time
Hours for Nessus Essentials/Professional install
days to weeks for production scanning programs with credentialed scanning, tuning, and reporting
Days for cloud-only scope
weeks for distributed enterprises with multiple scan engines and agent rollouts; complexity scales with environment size
Key integrations
Tenable Vulnerability Management, ServiceNow, Splunk, IBM QRadar, Microsoft…
Sentinel, Jira, Slack, AWS, Azure, GCP; Nessus API for custom integrations

Where it fits less well
Per-scanner licensing model
centralized cloud management requires the separately-licensed Tenable Vulnerability Management product; modern interactive dashboards are stronger in Tenable's cloud tier than in Nessus Professional
500-asset minimum commitment may not fit small deployments
initial setup and asset tagging involves planning; pricing often reported as competitive with Tenable/Qualys but final figure depends on negotiation
