IONIX Platform Capabilities & Detection Workflow

How does IONIX discover and validate exposures to zero-day vulnerabilities like CVE-2026-15210?

IONIX uses multi-factor discovery methods—including DNS analysis, certificate mapping, and metadata inspection—to map every internet-facing asset, including cloud instances, shadow IT, and third-party platforms. For zero-days, IONIX continuously analyzes dozens of threat intelligence feeds and applies AI to evaluate exploitability. It filters vulnerabilities by attacker-centric criteria (e.g., reachability, authentication requirements, active exploitation) and transforms real-world PoCs into safe, non-intrusive test payloads for validation. This process ensures only exploitable exposures are prioritized for mitigation. Note: Validation is limited to externally reachable assets and may not cover internal-only systems.

What is Preemptive Exposure Mitigation (PEM) and how does IONIX deliver it?

Preemptive Exposure Mitigation (PEM) is IONIX's approach to not just managing but actively mitigating external exposures before attackers can exploit them. IONIX discovers the full external attack surface—including unknown assets and digital supply chain dependencies—validates which exposures are actually exploitable, and mitigates them through automated workflows and integrations. The platform operates across the CTEM lifecycle (discover, validate, prioritize, mitigate, verify) at machine speed, with humans governing policy and priorities. Note: PEM effectiveness depends on continuous monitoring and external visibility; internal-only assets require separate controls.

What is Live Exposure Defense and what is the 12-hour SLA?

Live Exposure Defense is an IONIX capability that commits to identifying every potentially affected asset within 12 hours of a new CVE's publication, with exploitability validation completed in the same window. This enables organizations to respond to zero-day threats at machine speed, reducing mean time to remediation (MTTR) and limiting exposure windows. Note: The 12-hour SLA applies to externally discoverable assets; internal-only systems may not be covered.

How does IONIX prioritize exposures for remediation?

IONIX prioritizes exposures based on asset criticality, exploitability, and blast radius. The platform bundles issues into remediation clusters and routes them through integrations with ticketing, SOAR, and SIEM tools. This approach reduces noise, focuses teams on actionable threats, and shortens MTTR. Note: Prioritization is based on external visibility and validated exploitability; organizations should supplement with internal risk context as needed.
