Hadrian vs Tenable ASM: which ASM tool takes an exposure further?
THE SHORT ANSWER
Hadrian scores higher overall on our weights, 6.60 to 5.40. Hadrian scores higher on Routes to an owner, Proves exploitability, Closes the loop and Buying transparency; Tenable ASM scores higher on Contains before the patch and Fits the enterprise stack; they tie on Finds the unlisted estate. The table below gives the reason for every score.
Hadrian
Rank 4 of 10
Best for: Teams replacing periodic external pentests with continuous, agent-based proof
Tenable ASM
Rank 7 of 10
Best for: Tenable One customers who want external assets in the same exposure view
Which tool scores higher on each criterion?
| Criterion | Hadrian | Tenable ASM | Higher |
|---|---|---|---|
Finds the unlisted estate 15%WhyHadrian: Scans hourly or on events to keep the external inventory current; subsidiary mapping is not documented. Tenable ASM: Draws on an attack surface map of more than 5 billion assets to find domains related to your inventory. | 7 / 10 | 7 / 10 | Tie |
Routes to an owner 10%WhyHadrian: Machine learning confirms whether an asset belongs to the organization. Tenable ASM: Adds context from 200+ metadata fields; subsidiary or owner attribution is not described. | 7 / 10 | 6 / 10 | Hadrian |
Proves exploitability 20%WhyHadrian: Agentic AI exploits issues to prove impact; Hadrian states it proves exploitability within 15 minutes. Tenable ASM: Tenable One adds attack path analysis across 150+ techniques; the ASM product does not document exploit testing. | 9 / 10 | 5 / 10 | Hadrian |
Contains before the patch 20%WhyHadrian: No edge rule, playbook or other compensating control is described. Tenable ASM: Hexa AI orchestrates automated remediation in Tenable One; no edge control is described for ASM itself. | 2 / 10 | 4 / 10 | Tenable ASM |
Closes the loop 15%WhyHadrian: Remediation guidance, automatic tickets and automatic regression testing after a fix. Tenable ASM: Workflow runs through Tenable One and its connectors rather than ASM alone; no retest described. | 9 / 10 | 5 / 10 | Hadrian |
Fits the enterprise stack 10%WhyHadrian: Names Jira, ServiceNow, GLPI, Slack, Microsoft Teams, SentinelOne, Datadog, Zendesk and HubSpot plus an API. Tenable ASM: External findings land in Tenable One beside Tenable's vulnerability data, with Tenable One Connectors for third-party sources. | 6 / 10 | 9 / 10 | Tenable ASM |
Buying transparency 10%WhyHadrian: NOVA pentests from 1,250 euros per test excluding VAT, and ATLAS on AWS Marketplace at $50,000 per 12 months for up to 250 assets. Tenable ASM: ASM is quote-only, although Tenable lists prices for adjacent products such as Tenable One Vulnerability Management. | 7 / 10 | 3 / 10 | Hadrian |

Which should you choose?
Choose Hadrian if
- it matters most to you that it proves exploitability (9/10)
- it matters most to you that it closes the loop (9/10)
Choose Hadrian if you want continuous, attack-based proof in place of periodic external pentests, with a price you can see. Look elsewhere if you need edge mitigation or attribution across many subsidiaries.
Choose Tenable ASM if
- it matters most to you that it fits the enterprise stack (9/10)
- it matters most to you that it finds the unlisted estate (7/10)
Choose Tenable ASM if Tenable One is already your exposure platform. Look elsewhere if you want an ASM tool that proves and contains exposures on its own.
