Licensing

This topic breaks down the Tenable One licensing process and lists the versions and components you can purchase. It also holds a license calculator with which you can estimate your license needs.

To learn how to use Tenable One, see Tenable One Platform.

Licensing Tenable One

To use Tenable One, you purchase licenses for assets: resources identified by—or managed in—your Tenable products. Some Tenable One products use different asset types. For example, in Tenable Web App Scanning, assets are unique fully qualified domain names (FQDNs), while in Tenable Identity Exposure, they are enabled users in your directory service. Once you have purchased licenses, your Tenable representative assigns them to your products based on the asset types you want to scan or manage.

When your environment expands, so does your asset count, so you purchase more licenses to account for the change. Tenable licenses use progressive pricing, so the more you purchase, the lower the per-unit price. For prices, contact your Tenable representative.

You can reallocate your licenses once per 90 days. For example, if you purchase 1,000 licenses and assign 500 each to Tenable Vulnerability Management and Tenable Security Center, you can switch 100 licenses to Tenable Vulnerability Management if your scan profile requires it. To reallocate licenses, contact your Tenable representative.

Tip: To view your current license count and available assets, in the Tenable top navigation bar, click

and then click License Information. To learn more, see License Information Page.

Note: Tenable offers simplified pricing to managed security service providers (MSSPs). To learn more, contact your Tenable representative.

Tenable One Components

You can customize Tenable One for your use case by adding components. Some components are add-ons that you purchase.

Tip: The latest version of the platform is called Tenable One, but there were previously two versions: Enterprise and Standard. The following table lists all versions, but if you are a new customer, you will purchase Tenable One. If you have a Tenable One Standard or Enterprise quote, Tenable will honor it through the end of 2024. If you are a current customer, you can upgrade, downgrade, or renew as follows:

Current Tenable One Standard customers — You can upgrade, downgrade, or renew the same version through the end of 2025.
Current Tenable One Enterprise customers — You can upgrade, downgrade or renew the same version for the foreseeable future.

Version	Version Type	Included with Purchase	Add-on Component
Tenable One	Current version	Tenable Security Center+ companion license. OT Security companion license. Tenable Web App Scanning on-premises companion license.	If using Tenable Security Center, purchase additional consoles when you need more than three. Tenable Web App Scanning additional concurrency with Tenable cloud scanners. Tenable One Identity Exposure On-Premises.
Tenable One Standard	Legacy version	Tenable Security Center+ companion license. OT Security companion license. Tenable Web App Scanning on-premises companion license.	Tenable Web App Scanning additional concurrency with Tenable cloud scanners.
Tenable One Enterprise	Legacy version	Tenable Security Center+ companion license. OT Security companion license. Tenable Web App Scanning on-premises companion license.	If using Tenable Security Center, purchase additional consoles when you need more than three. Tenable Web App Scanning additional concurrency with Tenable cloud scanners. Tenable Attack Surface Management Daily Frequency.

Tenable One Asset Values

Tenable One has a centralized platform approach, collecting data from many asset types and providing domain-specific security teams (for example, Tenable Vulnerability Management, Tenable Cloud Security) with specialized domain-specific applications. These applications are similar to point products for managing cloud, web applications, OT assets, and so on, enhanced with context from the Tenable One platform.

The value customers derive from Tenable One varies by the type of resource being managed, as does the cost incurred by Tenable. To align Tenable One pricing to value, we convert the number of different resource types (for example, web servers, cloud resources, OT devices) to a number of Tenable One assets based on ratios defined in the following table. In this way we maintain a single price per Tenable One asset no matter the variety of resources being managed.

Reclaiming Licenses

When you purchase Tenable licenses, your total license count is static for the length of your contract unless you purchase more licenses. However, Tenable One products reclaim licenses under some conditions—and then reassign them to new assets in the same product so that you do not run out of licenses.

Exceeding the License Limit

To allow for usage spikes due to hardware refreshes, sudden environment growth, or unanticipated threats, Tenable One licenses are elastic. However, when you scan more assets than you have licensed, Tenable clearly communicates the overage and then reduces functionality in three stages.

Scenario	Result
You scan more assets than are licensed for three consecutive days.	A message appears in Tenable Exposure Management.
You scan more assets than are licensed for 15+ days.	A message and warning about reduced functionality appears in Tenable Exposure Management.
You scan more assets than are licensed for 30+ days.	A message appears in Tenable Exposure Management; scan and export features are disabled.

Tip: Improper scan hygiene or product misconfigurations can cause scan overages, which result in inflated asset counts. To learn more, see Scan Best Practices.

Expired Licenses

The Tenable One licenses you purchase are valid for the length of your contract. 30 days before your license expires, a warning appears in the user interface. During this renewal period, work with your Tenable representative to add or remove products or change your license count.

After your license expires, you can no longer sign in to the Tenable platform.
