Tenable and VulnTrek both call themselves exposure management platforms, but they start from opposite ends. Tenable owns the scanners and builds the platform on its own sensor data. VulnTrek runs no scanners at all and adjudicates the findings produced by the tools you already own — Tenable's included.
This is a direct comparison written by the VulnTrek team. We say where Tenable has genuine strengths — several of them are decisive — and where we think VulnTrek is the stronger fit. Where we could not confirm a capability from Tenable's public pages, the table says “Not documented” rather than claiming the capability is absent.

VulnTrek: Unified Exposure Management & Security Assurance Platform: explainable prioritisation, governed remediation, immutable audit evidence. Vendor-neutral by design.
Tenable: Tenable One, described as an AI-powered exposure management platform built on Tenable's own exposure dataset, with an Exposure Data Fabric and a Hexa agentic layer.
VulnTrek: None. VulnTrek never scans your estate; it consumes findings from the scanners and sensors you already run.
Tenable: First-party sensors across the portfolio — Nessus, vulnerability management, web application scanning, cloud, OT/IoT and external attack surface discovery.
VulnTrek: 55+, depth-first — every source normalised to one canonical finding schema, with no first-party sensor to favour.
Tenable: 300+ data integrations alongside Tenable's own sensors; third-party connector data is licensed as part of the platform.
VulnTrek: Intake-first semantic deduplication: 94% accuracy on a labeled set of 2,000 findings across Nessus, Qualys and Burp, reversible and audited.
Tenable: Asset deduplication through the Tenable UUID and an authoritative-source hierarchy, documented in the licensing guide; a published cross-vendor finding-level accuracy figure is not documented.
VulnTrek: Netra plus eight named, purpose-scoped agents bound to AEDE stages; every external change needs human approval.
Tenable: Hexa agentic layer with built-in, third-party and customer-built agents covering workflows, remediation, orchestration and exploitability verification, metered by an AI token capacity.
VulnTrek: VulnTrek Risk Index (VRI), fully decomposable: CVSS, EPSS, CISA KEV status, graded internet exposure, asset and business context, plus modelled annualised loss expectancy in EUR.
Tenable: Normalised cross-domain risk scores, benchmarks and attack path analysis, drawing on Tenable Research threat intelligence and business context.
VulnTrek: Yes — modelled annualised loss expectancy and breach likelihood in EUR.
Tenable: Business-aligned risk metrics and benchmarking are published; a monetary loss model is not documented on public pages.
VulnTrek: Safety-aware scoring that respects process criticality, mapped to IEC 62443 and NIST SP 800-82, applied to OT findings from the tools you already run.
Tenable: Tenable One OT Exposure: purpose-built cyber-physical coverage with OT asset discovery, Safe Active Query device interrogation and anomaly detection.
VulnTrek: Pramana Ledger: append-only evidence chain with actor attribution, mapped to ISO 27001, NIS2, DORA, CRA and the EU AI Act. Mappings are presentation-only and never change severity, deadlines or history.
Tenable: Audit report artifacts, dashboards and configuration and compliance audit policies; specific EU framework mappings such as NIS2, DORA and the CRA are not documented on public product pages.
VulnTrek: Decision coverage without running the scanners — VulnTrek adjudicates AppSec findings but is not a build gate replacement.
Tenable: Web application scanning (DAST) covering the OWASP Top 10, vulnerable components and APIs, sold as its own component.
VulnTrek: AI assets treated as exposure surface inside AEDE, with governed identification.
Tenable: AI discovery of shadow AI, AI workloads and externally exposed AI components, with AI user and app governance offered as an add-on.
VulnTrek: Yes — daily CISA KEV mirror, EU Vulnerability Database, IT and OT advisories, per-CVE pages and a hosted MCP server, no signup.
Tenable: Extensive free research, blog and plugin content; a free machine-readable exposure API for non-customers is not documented.
VulnTrek: Published plan structure with founder-led onboarding; no scanner licences to buy because VulnTrek reuses the tools you own.
Tenable: List prices published for several components — Nessus Professional at 4,790 USD and Nessus Expert at 6,790 USD per year, Tenable One Vulnerability Management from 3,700 USD for up to 250 assets — with the full Tenable One platform quoted per asset.
VulnTrek: Published and explicit: agents recommend, policy governs, humans approve every external change, evidence remains. Kill switch, daily caps, allow-listed non-mutating actions, append-only action ledger.
Tenable: Agent usage and governance is documented at the token-capacity level; a published refusal boundary for agent actions is not documented.
Tenable's platform rests on its own sensors — Nessus, cloud, web application and OT scanning — backed by Tenable Research. If you have no assessment capability yet, Tenable can sell you the whole chain from discovery to reporting. VulnTrek runs no scanners at all and is worthless without a source of findings.
Tenable One OT Exposure does asset discovery inside industrial networks, including Safe Active Query device interrogation and anomaly detection. VulnTrek scores and governs OT findings with safety awareness, but it does not discover OT assets. In an unmapped plant network, Tenable answers a question we cannot.
Vulnerability management, web application scanning, cloud, identity, attack surface management, AI discovery and OT are all available under one platform licence. For teams that want one vendor, one contract and one support line, that consolidation has real operational value.
Tenable is a public company with two decades of vulnerability assessment history, published pricing, extensive documentation and broad analyst and peer-review coverage. VulnTrek is the younger platform without independent analyst coverage yet, and that asymmetry is legitimate in a procurement process.
A platform built on its own sensors is at its best when its own sensors produce most of your findings. Most enterprises are not in that position: they run several scanners, a cloud security tool, an EASM service and a pentest programme. VulnTrek normalises every one of those to a single canonical finding schema — Tenable output included — and adjudicates them with no preference for whose sensor produced them.
Overlap between two scanners from different vendors is where backlogs quietly double. VulnTrek deduplicates at intake with 94% accuracy on a labeled set of 2,000 findings across Nessus, Qualys and Burp, and every merge is reversible and recorded. That number is published because it is the number that decides whether a mixed-tool estate gets smaller or louder.
If you fall under NIS2, DORA, CRA or the EU AI Act, the Pramana Ledger records every prioritisation decision, override, exception and remediation action with actor attribution and timestamp, append-only. Evidence is a continuous chain of custody rather than a report artifact you generate before an audit.
The VulnTrek Risk Index is fully decomposable: every score exposes the weight of CVSS, EPSS, CISA KEV status, graded internet exposure, asset and business context, and the modelled annualised loss expectancy in EUR. A CISO can defend any prioritisation to a board or regulator without the vendor in the room.
We publish what our agents will never do: no autonomous patching, no firewall or IAM mutation, no unapproved commits, no self-approval, no cross-tenant data use, no inline LLM gateway. The guardrail contract is enforced in code and auditable. Where you must demonstrate AI oversight to an auditor, that documentation is itself the deliverable.
Because VulnTrek assesses nothing, changing scanner does not change your platform, and your platform cost does not follow your scanner licence. You can replace a scanner, add a second one for coverage, or run a pentest supplier alongside both, and the decision layer, history and evidence chain stay intact.
We mirror CISA KEV, the EU Vulnerability Database and IT/OT vendor advisories daily, and publish per-CVE exploit context plus a hosted MCP server with no signup, no API key and no rate-limited trial.
No. VulnTrek runs no scanners, so it cannot replace a vulnerability assessment tool. The two sit at different layers: Tenable finds vulnerabilities, VulnTrek decides which of them matter across every source you have and records why. Most VulnTrek customers keep their scanners, Tenable included, and connect them.
Yes. Tenable output is one of the sources VulnTrek normalises to its canonical finding schema, and Nessus is one of the three tools in the labeled 2,000-finding set behind our published 94% deduplication accuracy.
For raw source count, quite possibly. VulnTrek's 55+ connectors cover the vulnerability management, attack surface, cloud security, endpoint and threat intelligence sources that drive infrastructure, cloud and OT exposure programmes, and every one lands in the same canonical schema — which is what makes deduplication across mixed vendors reliable rather than approximate. Breadth decides what you can ingest; schema depth decides whether ingesting it reduces the backlog.
Tenable's Hexa layer covers built-in, third-party and customer-built agents for workflows, remediation, orchestration and exploitability verification, governed through an AI token capacity. VulnTrek publishes an explicit refusal list of actions its agents will never take regardless of instruction, backed by a kill switch, daily caps, allow-listed non-mutating actions and an append-only ledger of every agent action. Both keep humans in the loop; we publish the boundary as a contract.
VulnTrek. The Pramana Ledger provides an append-only evidence chain with control mapping to NIS2, DORA, CRA, the EU AI Act and ISO 27001, and records every decision, override, exception and remediation action with actor attribution. Tenable provides audit report artifacts and compliance audit policies, but specific EU framework mappings are not documented on their public product pages.
It depends on which half of the problem you have. Tenable One OT Exposure discovers and interrogates industrial assets, which VulnTrek does not do. VulnTrek applies safety-aware scoring that respects process criticality, aligned to IEC 62443 and NIST SP 800-82, to OT findings from whichever tools produce them. In a converged estate the two are complementary rather than competing.
They are not directly comparable, because Tenable's price includes the assessment capability and VulnTrek's does not. Tenable publishes list prices for several components — Nessus Professional at 4,790 USD and Nessus Expert at 6,790 USD per year, and Tenable One Vulnerability Management from 3,700 USD for up to 250 assets — with the full platform quoted per asset. VulnTrek is priced as a decision and assurance layer on top of tools you already pay for. Get quotes for both shapes before comparing numbers.
