By Tenable Holdings, Inc. · HQ Columbia, US · 4.4/5 Value-Position score (estimate)
Positioning guardrails
Best for
- Large enterprises and government agencies that need one platform to find, prioritise and fix exposures across IT, cloud, identity, OT and AI.
- Security teams consolidating point vulnerability scanners into risk-based, cross-domain exposure management.
- Organisations with heavy audit and compliance obligations (TISAX/ENX, EU AI Act alignment) that need evidence-backed reporting.
- Industrial and critical-infrastructure operators needing passive OT/IoT asset discovery and vulnerability detection.
- Multi-cloud teams wanting agentless CNAPP/CSPM coverage alongside vulnerability management.
Ideal size: 500+ employees; security team of 5+ people · Mature security programme with a dedicated vulnerability or exposure management owner
Not for
- Small businesses looking for a free or low-cost standalone vulnerability scanner.
- Buyers who want instant self-serve signup with published per-seat pricing and no sales cycle.
- Teams that only ever need a single-domain scanner and no platform consolidation.
- Organisations unwilling to run agents or credentialed scans across their estate.

Frequently asked questions
What does Tenable cost?
Tenable publishes entry pricing rather than full list pricing. Tenable One Vulnerability Management starts at $3,500 per year for 100 assets (multi-year terms reduce the annual rate), Tenable One Web App Scanning starts at $3,578 per year for 5 FQDNs, Nessus Professional is $4,790 for one year and Nessus Expert is $6,790 for one year. Larger estates, Tenable One platform bundles and OT or identity modules are quoted by Tenable or a reseller. Advanced Support is a $400 per year add-on.
How long does it take to get value from Tenable?
Smaller deployments move quickly: Nessus and the cloud-based vulnerability management module are self-serve and can be running within days, and the vendor offers free trials of vulnerability management, web app scanning and Nessus. A full Tenable One rollout across IT, cloud, identity and OT typically takes several weeks to a couple of months, because it involves agent or credentialed scan deployment, connector setup and tuning of prioritisation before results are trusted in production.
Does Tenable use AI, and which models power it?
Yes. Tenable Hexa AI is described as an always-on agentic fleet and the agentic engine of Tenable One, used for risk prioritisation, remediation orchestration and exposure analysis. Tenable states it is powered in part by Anthropic's Claude under a strategic partnership. Tenable also sells Tenable One AI Exposure, which maps LLM integrations, shadow AI and AI supply-chain risk. The reviewed pages do not state whether customers can supply their own model keys or how AI features are billed.
Which security certifications does Tenable hold?
The pages reviewed do not itemise certifications. Tenable maintains a trust portal covering the security and compliance of its cloud products, publishes product security advisories with an advisory mailing list and RSS feed, runs a vulnerability disclosure programme with HackerOne, and notes FedRAMP relevance through partner listings such as ServiceNow. Buyers with SOC 2, ISO 27001, HIPAA or FedRAMP requirements should confirm current attestations directly with Tenable before contracting.
Is Tenable suitable for small organisations?
It can be, but the fit is narrow. Nessus Professional and Expert are priced and packaged for individual practitioners and small security teams, and the cloud vulnerability management entry tier starts at 100 assets. However, the strategic value of Tenable One, its connectors and its OT, identity and cloud modules shows up mainly at enterprise scale, and the reviewed pages do not publish per-seat self-serve pricing, so small buyers should expect an assisted purchase process.
What support does Tenable provide?
Tenable states that technical support is reachable 24/7 via phone, chat or the Tenable Connect community portal, which also hosts the knowledge base, Q&A discussions and product announcements. Product cases and account management run through account.tenable.com. The Advanced Support add-on, $400 per year on Nessus licences, adds 24x365 phone, email, community and chat support, and Tenable offers a Technical Account Management guide for larger accounts.
