Paid
Free tier / trial
Free tier
Nessus Essentials free up to 16 IPs (or 5 IPs on 30-day trial of newer Essentials); 7-day trial of paid tiers
Free tier
Qualys Community Edition free (16 internal + 3 external assets + 1 web app); 30-day VMDR trial; 45-day Patch Management trial
Volume discounts
Multi-scanner deployments and multi-year terms reduce per-scanner cost
education program offers significant discounts for verified students/educators
Tiered breaks at 1,000, 5,000, 10,000+ assets
multi-year commitments reduce per-asset cost; bundling VMDR with other Qualys modules increases discount leverage
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
Virtual scanner appliances ($8K-$9K/yr each), Patch Management module (+15-25%…
over VMDR), Web Application Scanning, professional services for implementation, ServiceNow/CMDB integration may add cost
↗ 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
Cloud SaaS via Qualys Cloud Platform
virtual scanner appliances (~$8K-$9K/yr each) or physical for internal/segmented networks; agent-based scanning via Qualys Cloud Agent
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 assets
weeks for distributed enterprises requiring scanner appliances in multiple network zones; implementation services often $5K-$50K

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
Per-asset pricing scales with environment size and can be costly for larger deployments
advanced modules (Patch Management, WAS) are priced separately; smaller deployments may find more value in alternatives
