Censys ASM vs Cortex Xpanse: which ASM tool takes an exposure further?
THE SHORT ANSWER
Cortex Xpanse scores higher overall on our weights, 6.40 to 5.15. Censys ASM scores higher on Buying transparency; Cortex Xpanse scores higher on Finds the unlisted estate, Routes to an owner, Contains before the patch and Fits the enterprise stack; they tie on Proves exploitability and Closes the loop. The table below gives the reason for every score.
Censys ASM
Rank 9 of 10
Best for: Threat intelligence and hunting teams that want raw internet scan evidence
Cortex Xpanse
Rank 5 of 10
Best for: Palo Alto Networks Cortex estates that want automated response through XSOAR
Which tool scores higher on each criterion?
| Criterion | Censys ASM | Cortex Xpanse | Higher |
|---|---|---|---|
Finds the unlisted estate 15%WhyCensys ASM: First-party scanning across all 65K ports, expanding from seeds the customer adds. Cortex Xpanse: Palo Alto Networks states it scans all 4.3 billion IPv4 addresses several times a day and 500 billion+ ports daily. | 7 / 10 | 8 / 10 | Cortex Xpanse |
Routes to an owner 10%WhyCensys ASM: Assets found beyond your seeds appear under a "Found by Censys" tab; attribution logic is not described in detail. Cortex Xpanse: Identifies third-party stakeholders for exposures; subsidiary attribution detail is not on the pages reviewed. | 6 / 10 | 7 / 10 | Cortex Xpanse |
Proves exploitability 20%WhyCensys ASM: Confirms reachability and applies EPSS and KEV context; active exploitation testing is not documented. Cortex Xpanse: Exploitability validation is not described on the product pages reviewed; the emphasis is discovery and response. | 5 / 10 | 5 / 10 | Tie |
Contains before the patch 20%WhyCensys ASM: No compensating control is described. Cortex Xpanse: Active Response runs built-in automated playbooks against exposures; edge WAF rules are not named. | 2 / 10 | 7 / 10 | Cortex Xpanse |
Closes the loop 15%WhyCensys ASM: Auto-creates, routes and tracks remediation tasks; no retest after a fix is described. Cortex Xpanse: Routes and remediates through Cortex XSOAR playbooks; a retest after the fix is not described. | 6 / 10 | 6 / 10 | Tie |
Fits the enterprise stack 10%WhyCensys ASM: Names Jira, ServiceNow ITSM and CMDB, Tenable VM, Google Security Operations, Microsoft Sentinel, Axonius, Brinqa, Slack, Webex and the three major clouds. Cortex Xpanse: Native ties to Cortex XSOAR and Prisma Cloud inside the Palo Alto Networks Cortex portfolio. | 8 / 10 | 9 / 10 | Cortex Xpanse |
Buying transparency 10%WhyCensys ASM: A free platform account and credits from $100 exist; ASM itself is contact sales. Cortex Xpanse: No price from Palo Alto Networks; a UK G-Cloud reseller listing shows £70,850.84 per instance per year. | 4 / 10 | 3 / 10 | Censys ASM |

Which should you choose?
Choose Censys ASM if
- it matters most to you that it fits the enterprise stack (8/10)
- it matters most to you that it finds the unlisted estate (7/10)
Choose Censys ASM if your threat intelligence or hunting team wants raw scan evidence and broad integrations. Look elsewhere if you need exploitation proof or containment.
Choose Cortex Xpanse 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 (8/10)
Choose Cortex Xpanse if Cortex XSOAR already runs your response and you want exposures acted on by playbook. Look elsewhere if proof of exploitability is your main gap.
Frequently asked questions
Which proves exploitability better, Censys ASM or Cortex Xpanse?
