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 7

  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 3

  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 4

  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.

Microsoft Defender EASM wins on

• Integrations and platform reach: 8 vs 7

  Data connectors to Log Analytics and Azure Data Explorer and a Security Copilot integration in preview; no cross-tenant resource access.

• Pricing transparency: 7 vs 2

  Self-serve Azure billing against a published definition of billable assets (approved hosts, domains and IP addresses) after the trial.

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 Microsoft Defender EASM if

• The tool has to fit a wider security platform or many existing tools. Microsoft Defender EASM scores 8 on integrations: Data connectors to Log Analytics and Azure Data Explorer and a Security Copilot integration in preview; no cross-tenant resource access.
• You want results with the least setup. Microsoft Defender EASM scores 8 on time to value: 30-day free trial on the first resource, plus the prebuilt inventory.
