How much does Tenable Cloud Security cost in 2026?

Tenable Cloud Security is asset-based and quote-only. Vendr transaction data places the typical mid-market contract at $100,000 to $250,000 per year for 2,500 cloud workloads on the core Tenable One Cloud Exposure platform. Cloud Exposure Vulnerability Management uses a 1:1 agentless scanning consumption ratio, which simplifies licensing for ephemeral assets. Add-on modules (DSPM, AI-SPM, Identity Exposure) are priced separately (Vendr benchmark, 2026).

What counts as a billable resource in Tenable Cloud Security?

Billable resources include virtual machines, container hosts (Kubernetes and others), serverless functions and hosts, container images, container repositories, data stores, and databases. Tenable uses ratio-based licensing where different resource types convert to Tenable One assets: 1 VM equals 1 asset, 1 CIEM identity asset equals 0.5 assets, 1 CIEM billable asset equals 3 assets, 1 Cloud Exposure Standard billable asset equals 5 assets, and 1 Cloud Exposure Enterprise billable asset equals 7.5 assets (Tenable, 2026).

How does Tenable Cloud Security compare to Wiz?

Tenable Cloud Security typically carries lower per-workload pricing than Wiz for cloud-native environments, while offering broader coverage including on-premises and hybrid environments. Vendr transaction data places Tenable's typical annual contract minimum at $15,000 to $25,000 versus Wiz's $30,000 to $50,000. Buyers evaluating both vendors often achieve better pricing by demonstrating competitive evaluation. Estimated annual cost for 2,500 cloud workloads on the core platform runs $100,000 to $250,000 for Tenable versus $150,000 to $350,000 for Wiz (Vendr benchmark, 2026).

What hidden costs should I plan for with Tenable Cloud Security?

Three predictable costs sit beyond the asset-based license. Professional services for implementation runs $15,000 to $75,000 for mid-sized deployments. Premium support and dedicated technical account management are percentage surcharges on the asset subscription. Renewal uplift after the initial 12-month term averages 5 to 12 percent absent competitive pressure. Volume discounts typically apply at 2,500+ assets on multi-year terms (Vendr benchmark, 2026).

Tenable Cloud Security Pricing 2026: Per-Asset Cost

Q: Does Tenable Cloud Security support ephemeral assets?

Yes. Tenable One Cloud Exposure Vulnerability Management uses a 1:1 agentless scanning consumption ratio. The system averages the number of seen billable resources each day, and the quantity that counts against the license is the rolling 90-day average of those daily averages. This rolling-average approach handles ephemeral Kubernetes pods and short-lived cloud resources without spiking license consumption (Tenable, 2026).

Quick Answer

Tenable Cloud Security pricing in 2026 is asset-based and quote-only. Vendr benchmark data places the typical mid-market contract at $100,000 to $250,000 per year for 2,500 cloud workloads on the core Tenable One Cloud Exposure platform. Tenable Cloud Exposure Vulnerability Management uses a 1:1 agentless scanning consumption ratio for ephemeral asset support (Vendr benchmark, 2026).

Tenable's April 2026 pricing and packaging refresh introduced two packages — Foundation and Advanced — that simplify the platform-to-maturity journey for buyers moving from fragmented point tools.

Tenable One Cloud Exposure packages and what each unlocks

Tenable introduced Foundation and Advanced packages in April 2026 to simplify the platform entry path. Foundation establishes a unified program that helps teams understand which assets they have, the associated risks and severity, and how to address them. Foundation is the entry tier for organizations moving from fragmented, domain-specific tools toward consistent cross-environment visibility. Advanced matures the program from unified visibility to true exposure management by adding business context, attack path analysis, and prioritization by business risk (Tenable press release, April 2026).

Package	Best fit	Capabilities unlocked	Typical annual minimum
Foundation	Unified program start	Unified asset inventory, vulnerability management, cloud security posture, AI security, basic dashboards	$15,000 to $25,000
Advanced	Mature program maturity	Foundation plus attack path analysis, exposure scoring, business context, prioritization	$25,000 to $50,000
Cloud-native Application Protection (add-on)	CNAPP use case	CSPM, KSPM, CWPP, CIEM, DSPM, AI-SPM	Quote
AI User and App Governance (add-on)	AI risk use case	Identity governance for AI users and agents	Quote

The Foundation versus Advanced distinction is what to model when scoping the asset subscription. Foundation is sufficient for asset inventory and vulnerability management; Advanced is the right choice for organizations that need attack path analysis and business-context prioritization for risk remediation decisions (Tenable, 2026).

Tenable ratio-based asset licensing

Tenable converts different cloud resource types to a single Tenable One asset unit. The ratio model keeps the per-asset number consistent regardless of resource variety. The table below summarizes the published asset ratios that drive license consumption (Tenable ratio-based licensing guide, 2026).

Product	Resource type	Tenable One asset value
Tenable One Vulnerability Management	Hosts, IP addresses, scanned targets	1 asset per scanned target
Tenable One Web App Scanning	FQDNs or IP addresses	1 asset per FQDN or IP
Tenable One Identity Exposure	Human or machine identities	0.5 assets per identity
Tenable One Cloud Exposure CIEM	Billable assets (cloud compute, container hosts, serverless)	3 assets per billable asset
Tenable One Cloud Exposure Standard	Licenses allocated	5 assets per license
Tenable One Cloud Exposure Enterprise	Licenses allocated	7.5 assets per license
Tenable One OT Exposure	Detected devices with IP addresses	1.5 assets per device
Attack Surface Management (Fortnightly)	Observable objects (domains, subdomains, IPs)	0.25 assets per object
Attack Surface Management (Daily)	Observable objects	0.5 assets per object

A mid-market organization with 1,000 cloud workloads, 5,000 CIEM identities, and 100 web applications would consume approximately 1,000 + 5,000 × 0.5 + 100 = 3,600 Tenable One assets. At mid-market pricing of $80 to $150 per asset after negotiation, the annual contract lands at $290,000 to $540,000, consistent with the Vendr benchmark for a comprehensive Tenable Cloud Security deployment (Vendr benchmark, 2026).

Tenable One Flex pricing and packaging refresh

Tenable's April 2026 Flex pricing refresh added predictable spend and faster time-to-value. The Flex package model gives organizations flexibility to start where they are, expand over time, and move seamlessly across asset types and attack surfaces. The count-once licensing principle further supports predictable spend by allowing customers to deploy all relevant sensors on a single asset and be charged only once (Tenable press release, April 2026).

The Flex refresh is targeted at the new-customer procurement motion rather than renewing installed-base contracts. Buyers evaluating Tenable for the first time in 2026 should ask for the Flex package pricing specifically rather than the legacy asset-based quote. Buyers with installed-base contracts renewing in 2026 commonly negotiate a one-time migration to Flex at contract renewal rather than waiting for natural expiry (Tenable, 2026).

Ephemeral asset support and Kubernetes cost control

Tenable Cloud Exposure Vulnerability Management uses a 1:1 agentless scanning ratio for ephemeral assets. The system averages the number of seen billable resources each day, and the quantity that counts against the license is the rolling 90-day average of those daily averages. This rolling-average approach handles ephemeral Kubernetes pods, serverless functions, and short-lived cloud resources without spiking license consumption (Tenable, 2026).

The rolling-average mechanism is the key cost-control feature for Kubernetes-heavy estates. Without it, a workload that spins up for 30 minutes and disappears would still consume a license slot under traditional asset-count models. With the rolling-average, the contribution of that ephemeral workload to the daily average is minimal, and the 90-day average smooths out burst patterns. Buyers running large Kubernetes estates should verify that the quote explicitly references the 1:1 agentless scanning ratio and the rolling-average measurement methodology (Tenable ratio-based licensing guide, 2026).
