Ionix Capabilities for Zero-Day and CVE Response

How does Ionix detect and validate exposure to new zero-days like CVE-2026-81239?

Ionix uses multi-factor discovery methods (DNS analysis, certificate mapping, metadata inspection) to map every internet-facing asset, including cloud instances, third-party platforms, and shadow IT. Ionix continuously monitors dozens of threat intelligence feeds and applies AI to evaluate exploitability, even before public proof-of-concept code is released. The platform filters vulnerabilities by attacker-centric criteria and transforms real-world PoCs into safe, non-intrusive test payloads for validation. Note: Ionix's validation is non-disruptive but may not cover assets outside internet-facing scope.

What is Live Exposure Defense and how does it help with zero-day response?

Live Exposure Defense is an Ionix capability that commits to a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation running inside the same window.
