Tenable Prices (2025): Guide to Plans, Rates, Free and Paid Versions

Tenable, the recent winner of the 2025 Cloud 100 award, is a renowned cybersecurity company whose applications enable us to see, prioritize, and act on risk. With products that cover endpoints, the cloud, and identities all in a single exposure language on one platform, their vulnerability management offering focuses on providing truly comprehensive features and real scalability.

Additionally, Tenable holds the necessary ASV qualification to perform PCI vulnerability scans, certifying its competence and reliability. All of this is key for planning investments while consolidating operations on a single platform.

Tenable’s pricing model is based on assets, where each corresponds to a device with an IP address — servers, workstations, networks, and cloud workloads. The budget, therefore, scales at the same rate as the infrastructure, which is especially useful in hybrid environments with workloads on AWS, Azure, or Google Cloud, for example. It is also possible to request a personalized quote, allowing us to tailor pricing to the specific needs of each company.

From Tenable Nessus to Tenable Vulnerability Management, including Tenable Security Center and additional modules such as Tenable Web App Scanning and Tenable Cloud Security, the catalog caters to a range of users, from individual consultants to the largest enterprises.

Tenable Pricing Model

Tenable’s pricing philosophy focuses on annual subscriptions per asset, aligning price with the size and complexity of the environment to protect. The asset count considers any IP seen during the management window, and the service is offered as SaaS and also on-premises if maximum control is preferred.

• Per-asset and annual model with multi-year discounts for planning over 24 or 36 months.
• Asset definition aligned with seen IPs, including servers, workstations, and cloud instances.
• Scaling by modules, such as Tenable Web App Scanning, Tenable Cloud Security, or Identity Exposure.
• SaaS and on-prem options in Tenable Vulnerability Management and Tenable Security Center.
• Integrations and APIs for SIEM, ITSM, and DevSecOps enabling unified detection, prioritization, and response.

Free trial and demo upon request, to validate technical fit and review dashboards with real data from your organization.

Hidden Costs and Precautions of Tenable

Although the asset-based model provides great clarity, it is essential to consider several factors that influence the total cost of ownership to ensure the budget aligns with our goals.

• Definition of asset and counting windows per observed IP, relevant in environments with DHCP and ephemeral cloud, where the inventory often grows too quickly.
• Specialized modules such as Tenable Web App Scanning, PCI ASV, or OT/ICS require additional licensing beyond the base platform.
• Professional services for design, deployment, and enablement usually incur considerable costs in more complex projects.
• Advanced 24/7 support and premium SLAs are add-ons that enhance coverage and operational response times.
• Multiyear agreements and asset scaling during certain periods, it is advisable to plan with growth forecasts and consider seasonal campaigns.
