This Tenable Pricing Table for Nessus gives you a clear overview of the available plans, features, and costs. It helps you quickly compare the options and choose the right one for your needs.
Nessus Professional – $4,790/year
Nessus Professional is the standard commercial tier. It is a per-scanner license with unlimited IP scanning and no per-asset fees, making it predictable to budget.
It is used by independent consultants, penetration testers, and in-house security teams running periodic assessments.
Nessus Expert – $6,790/year
Nessus Expert includes everything in Professional plus three additional capabilities: web app scanning for up to 5 FQDNs, external attack surface discovery for up to 5 domains per quarter, and Infrastructure as Code (IaC) scanning.
Additional features in Nessus Expert:
- Web application scanning: Covers up to 5 FQDNs for OWASP Top 10 and API security vulnerabilities.
- External attack surface discovery: Discovers and assesses up to 5 external domains per quarter, surfacing internet-facing exposures you may not be actively monitoring.
- Infrastructure as Code (IaC) scanning: Audits Terraform, CloudFormation, and other IaC templates for misconfigurations before deployment.
- Cloud infrastructure auditing: Covers AWS, Azure, and GCP configuration assessments.
Advanced Support Add-on – $400/year
The base Professional and Expert licenses include Standard Support: a community portal, knowledge base, and self-service documentation.
Advanced Support adds 24×365 phone, email, chat, and community access for $400/year. Recommended for teams that rely on vendor support for troubleshooting credential failures or complex scan policy issues.
Multi-Year Pricing
Tenable offers 2-year and 3-year Nessus licenses at a reduced effective annual rate, visible at checkout on tenable.com/buy.
Given Tenable’s yearly tradition of raising prices every March 1st, purchasing a multi-year license locks in the current price and avoids successive annual increases – one of the highest-ROI decisions a Nessus buyer can make.
Nessus Professional vs. Expert – Full Feature Comparison
This Nessus Professional vs. Expert feature comparison gives you a quick overview of what each plan offers. It helps you easily understand which version is better suited for your security and scanning needs.
| Feature | Nessus Professional | Nessus Expert |
|---|---|---|
| Unlimited IP scanning | ✓ | ✓ |
| 100,000+ plugin checks | ✓ | ✓ |
| Compliance templates (PCI, CIS, STIG) | ✓ | ✓ |
| Real-time plugin updates | ✓ | ✓ |
| Live Results (offline scan updates) | ✓ | ✓ |
| PDF, HTML, CSV reporting | ✓ | ✓ |
| Web application scanning (5 FQDNs) | ✗ | ✓ |
| External attack surface discovery (5 domains/qtr) | ✗ | ✓ |

| Cloud infrastructure auditing (AWS/Azure/GCP) | ✗ | ✓ |
| Multi-year pricing | ✓ | ✓ |
| Advanced Support (add-on) | +$400/year | +$400/year |
Overall, both plans include strong core scanning features, but Nessus Expert offers advanced tools for web, cloud, and attack surface security. Choosing the right plan depends on your project size and security requirements.
The Free Tier – Nessus Essentials
Nessus Essentials is the free tier, but it is more restricted than many older guides describe. The current free Essentials license is a 30-day evaluation covering only 5 IPs.
Once the evaluation period expires, scan history is lost unless you upgrade. For most environments, even a small 10-person team – 5 IPs is insufficient.
Nessus Essentials is suited to students, lab environments, and personal learning, not production security programs.
Tenable Vulnerability Management Pricing
Tenable Vulnerability Management (formerly Tenable.io) is the cloud-managed SaaS platform built for teams that need continuous asset discovery, multi-scanner management, and centralized dashboarding – capabilities that standalone Nessus Professional cannot provide.

Other Tenable Pricing & Products
Other Tenable pricing & products cover a range of plans, from basic scanning tools to advanced enterprise security solutions. This section gives a quick overview of the available options.
Tenable Cloud Security
Tenable Cloud Security (formerly Tenable.cs) is a CNAPP covering CSPM, CIEM, DSPM, and vulnerability management for cloud workloads across AWS, Azure, and Google Cloud.
Pricing is based on the number of billable resources – virtual machines, container hosts, serverless functions, data stores, and databases.
Custom quote only; use Tenable’s cloud sizing tool at tenable.com/cloud-security/pricing to estimate resource counts.
Tenable OT Security
Purpose-built for operational technology environments, manufacturing, energy, utilities, and critical infrastructure, where traditional IT scanners cannot safely operate.Uses passive monitoring to avoid disrupting OT systems.
Custom pricing per OT asset. Government pricing data shows a 30-day assessment consulting license (500 device max) at approximately $12,244, and a full remote implementation at approximately $20,375, giving a sense of entry-level professional services costs.
Tenable Identity Exposure
Maps Active Directory attack paths and misconfigurations that allow privilege escalation or lateral movement. Custom pricing per Active Directory identity. Available standalone or bundled within Tenable One.
What Drives Tenable Pricing?
Understanding what makes Tenable costs go up or down helps you budget accurately and negotiate more effectively.
1. Asset Count and Scope
Most Tenable products use asset-based pricing. Volume discounts commonly apply at thresholds of 1,000, 5,000, and 10,000 assets – hitting a volume tier can significantly reduce per-asset costs.
2. Product Tier
Bundled platforms like Tenable One cost significantly more than single products. Only purchase products you will actively use; adding Tenable One features you don’t need is the fastest way to overpay.
3. Deployment Model
On-premises Security Center deployments typically have a higher total cost of ownership when you factor in hardware, implementation professional services, and annual maintenance fees.
4. Contract Duration
Multi-year agreements (2–3 years) unlock meaningful volume discounts. Tenable’s sales team has more flexibility on larger, longer deals – this is the most reliable source of enterprise discount leverage.
5. Add-On Modules
Web App Scanning, Cloud Security, Identity Exposure, and Lumin are typically sold separately. Buyers who negotiate bundled pricing upfront consistently achieve lower per-module costs than those who add capabilities incrementally.
6. Annual Price Increases
Tenable raises Nessus prices every year, effective March 1st. The 2026 increase took effect on March 2, 2026.
Purchasing or renewing before the annual deadline, or locking in multi-year pricing, is the most effective way to manage this predictable cost factor.
Hidden Costs to Watch
- Annual Maintenance on Perpetual Licenses: Security Center perpetual licenses carry ongoing fees of 18-22% of the license cost per year indefinitely.
- Professional Services: Implementation for Security Center, Tenable One, and OT Security almost always requires professional services. These range from ~$7,700 for a remote deployment to $20,000–$40,000+ for onsite enterprise projects.
- Overage Fees: Exceeding contracted asset counts mid-term triggers overage fees at higher per-asset rates. Negotiate flexible asset bands upfront.
- Training Costs: Nessus Fundamentals training is $275 as an optional add-on. Advanced certifications add further cost, though Tenable periodically bundles free training with newsletter promotions.
- Storage and Data Retention: Retaining scan data beyond the standard retention window (typically 90-365 days) may incur additional storage fees on cloud-based platforms.
How to Save on Tenable Pricing?
To save on Tenable pricing, choose only the tools and features your business actually needs, and prefer annual plans for better long-term savings. Before purchasing, use the free trial to check whether the platform fits your requirements.
You can also look for an active Tenable coupon code or seasonal promo offer, as some deals may include discounts on selected plans and Nessus subscriptions.
Large businesses may also be able to negotiate custom enterprise pricing for even better value.
Buy Before March Each Year
Tenable raises Nessus prices every year in early March. Purchasing or renewing before the annual March deadline locks in the lower price for the full contract term.
Use Multi-Year Licensing
Multi-year Nessus licenses (2 or 3 years) lower the effective annual cost and protect against successive March price increases. Savings are displayed at checkout on tenable.com/buy.
Subscribe to the Newsletter
Tenable periodically sends subscribers exclusive promotional codes, typically 20% off Nessus Professional or Expert, often bundled with free on-demand training worth $275. This is the most reliable path to mid-year discounts.
Wait for Black Friday
The Tenable Black Friday sale is the deepest annual discount, historically 40% off Nessus Professional and Expert.
In 2025, code BFnessus40 ran from November 28 to December 2 and saved buyers up to $2,716 on a Nessus Expert license. Combining Black Friday with a multi-year purchase produces the maximum possible savings.
Negotiate Module Bundles
For enterprise products, negotiating bundled pricing for all modules you plan to use within 2-3 years, rather than adding them incrementally, consistently produces lower total cost. Tenable’s sales team has more flexibility on larger deal values.
Education & Non-Profit Discounts
Educational institutions and non-profits may qualify for 10-20% off Nessus or Tenable Vulnerability Management. Contact sales@tenable.com directly to verify eligibility.
What Is the Cost of a Tenable VM?
Tenable Vulnerability Management is licensed by annual subscription and priced by asset, not by IP address.
An asset is any unique device with an IP address: servers, workstations, cloud workloads, containers, and network devices. Tenable’s proprietary asset-counting algorithm uses multiple attributes to identify unique assets and reduce duplication.
How Much Does Tenable Nessus Cost in 2026?
Nessus is Tenable’s standalone vulnerability scanner and the foundation of the entire product line. It has been the world’s most widely deployed scanner for over two decades.
Tenable raised Nessus Pro and Expert prices effective March 2, 2026, as part of its annual pricing tradition. Prices below reflect post-increase rates.

Conclusion: Which Tenable Plan Is Right for You?
Tenable pricing spans a wide range – from free Nessus Essentials to $500,000+ enterprise contracts for Tenable One.
The right product is determined by three questions: How many assets do you need to cover? Do you need standalone periodic scanning or continuous cloud-managed monitoring? And do you require on-premises deployment, or can you use SaaS?
For most individual security professionals and small teams, Nessus Professional at $4,790/year is the correct starting point.
For teams managing hundreds of assets across multiple sites, Tenable Vulnerability Management provides the centralized management and continuous visibility that Nessus Professional cannot.
For enterprises needing to cover IT, cloud, web apps, OT, and identity in a single platform, Tenable One offers genuine consolidation value despite its cost.
