Tenable Pricing 2026: Ultimate Guide for Security Products

Tenable pricing is structured across four distinct tiers, based on deployment scale and feature depth. At the entry level, Tenable offers standalone vulnerability scanners with fixed annual pricing: Nessus Professional at $4,390/year and Nessus Expert at $6,390/year. 

For organizations needing centralized, cloud-based vulnerability management, Tenable Vulnerability Management and Tenable Web App Scanning are available as subscriptions starting at $3,500+ per year, with costs increasing as asset coverage and modules expand.

Note: Tenable prices vary based on geo. The pricing presented in our article is US-specific.

At the enterprise level, advanced platforms such as Tenable One and on-premises solutions use quote-based pricing, tailored to asset volume, deployment model, and bundled capabilities. 

How much does Tenable cost?

In 2026, Tenable’s pricing is designed to scale with organizations of all sizes, from small businesses securing a few assets to global enterprises managing complex hybrid infrastructures.

Tenable Vulnerability Management starts at approximately $3,500+ per year, with pricing increasing based on the number of assets, cloud connectors, and add-on modules like Web App Scanning or Container Security.

Tenable.sc (on-premises solution) uses quote-based pricing, appealing to organizations with internal infrastructure and compliance mandates requiring on-site control.

Tenable One, the unified exposure management platform, is quote-based and is typically adopted by medium- to large-sized enterprises, with pricing based on the environment’s size and the number of integrated modules.

Tenable Nessus Pro, the standalone scanner for individual security professionals, remains affordable at $4,390 per year for a single-user license.

Tenable also provides flexible licensing models that include volume discounts, custom enterprise bundles, and usage-based options for cloud-native and DevOps-focused teams. Whether you’re prioritizing vulnerability visibility, risk reduction, or regulatory compliance, Tenable offers tailored packages to match your goals.

What Tenable doesn’t do is investigate live threats, suppress alert noise, or respond when attackers act. UnderDefense MAXI does. UnderDefense MAXI integrates seamlessly with Tenable, turning vulnerability context into a real-time AI-assisted investigation. It only escalates validated issues to a SOC analyst, cutting alert noise and allowing organizations to save on in-house SOC.

How can UnderDefense help improve Tenable productivity?

UnderDefense MAXI is a security-as-a-service platform focused on real-time detection, investigation, escalation, and response to threats flowing through your environment, including cloud, networks, endpoints, and logs. It layers AI, automation, and expert SOC support on top of your existing security telemetry.

Tenable excels at identifying vulnerabilities, but security teams still face the challenge of turning scan results into fast, confident action. UnderDefense MAXI integrates directly with Tenable to operationalize vulnerability data inside live detection and response workflows.

UnderDefense MAXI enriches security alerts with vulnerability context, correlates them with real-time telemetry, and filters out low-risk activity. Only validated, high-impact threats are escalated to human analysts. This reduces alert fatigue, shortens investigation cycles, and allows teams to get more value from Tenable without expanding internal SOC headcount.
