IONIX wins on

• Discovery of unknown assets and subsidiaries: 9 vs 7

  Its Connective Intelligence engine recursively maps internet-facing assets, including shadow IT, subsidiaries and third- and fourth-party assets in the digital supply chain.

• Attribution accuracy and false-positive handling: 8 vs 6

  Automatically attributes each asset to the relevant subsidiary or business owner; IONIX's claim of fewer false positives is its own and not verified here.

• Exploitability validation: 8 vs 5

  Confirms exploitability with non-intrusive exploit simulations; less aggressive than the attack-agent approaches documented by Hadrian and watchTowr.

• Remediation and mitigation support: 9 vs 6

  Turns new CVEs into deployable WAF rules for virtual patching, and its Active Protection claims hijackable domains and cloud buckets on the customer's behalf.

• Time to value: 8 vs 6

  States "immediate time-to-value" with minimal resources; the inputs needed to start are not published on the pages reviewed.

Tenable ASM wins on

• Integrations and platform reach: 9 vs 7

  Feeds Tenable One alongside vulnerability, cloud, OT and identity exposure data, with Tenable One Connectors for third-party sources.

• Pricing transparency: 3 vs 2

  ASM is quote-only, although Tenable publishes prices for adjacent products such as Tenable One Vulnerability Management.

Choose IONIX if

• You want help closing exposures, not only a longer list of them. IONIX scores 9 on remediation: Turns new CVEs into deployable WAF rules for virtual patching, and its Active Protection claims hijackable domains and cloud buckets on the customer's behalf.
• Finding unknown assets, subsidiaries and acquired infrastructure is your main gap. IONIX scores 9 on discovery: Its Connective Intelligence engine recursively maps internet-facing assets, including shadow IT, subsidiaries and third- and fourth-party assets in the digital supply chain.

Choose Tenable ASM if

• The tool has to fit a wider security platform or many existing tools. Tenable ASM scores 9 on integrations: Feeds Tenable One alongside vulnerability, cloud, OT and identity exposure data, with Tenable One Connectors for third-party sources.
• Finding unknown assets, subsidiaries and acquired infrastructure is your main gap. Tenable ASM scores 7 on discovery: Draws on an attack surface map of more than 5 billion assets to identify domains related to the buyer's inventory.
