IONIX Capabilities for Zero-Day and CVE Response
How does IONIX help organizations detect and mitigate exposures to zero-days like CVE-2026-21579?
IONIX's External Exposure Management platform continuously discovers all internet-facing assets, including those running Atlassian Confluence Data Center. When a new zero-day like CVE-2026-21579 is published, IONIX's Live Exposure Defense commits to a 12-hour SLA: within 12 hours of CVE publication, IONIX identifies every potentially affected asset and runs exploitability validation. The platform then prioritizes exposures, routes findings through integrations with ticketing, SOAR, and SIEM tools, and provides actionable, plain-language remediation guidance. Note: IONIX does not patch software; it identifies, validates, and drives mitigation of exposures. Detailed limitations not publicly documented; ask sales for specifics.
What is Live Exposure Defense and how does it support zero-day response?
Live Exposure Defense is an IONIX capability that guarantees a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation inside the same window. This enables organizations to respond to zero-days like CVE-2026-21579 before attackers can exploit them. Note: Live Exposure Defense does not remediate vulnerabilities directly; it accelerates detection and validation for rapid mitigation. Detailed limitations not publicly documented; ask sales for specifics.
How does IONIX validate exploitability for new vulnerabilities?
IONIX transforms real-world proof-of-concept exploits into safe, non-intrusive test payloads that run in production environments without disruption. These validations are precisely targeted to vulnerable systems, ensuring rapid confirmation of exploitability. Only assets that are externally reachable and match the affected software and version are tested. Note: IONIX does not perform intrusive or destructive testing. Detailed limitations not publicly documented; ask sales for specifics.
How does IONIX reduce noise and prioritize remediation for zero-day exposures?
IONIX filters vulnerabilities by attacker-centric criteria: internet reachability, authentication requirements, and evidence of active exploitation. The platform eliminates false positives and bundles issues into remediation clusters prioritized by asset criticality, exploitability, and blast radius. This approach shortens mean time to remediation (MTTR) and enables teams to focus on exposures that matter. Note: Prioritization is based on external exposure and exploitability, not internal risk ratings. Detailed limitations not publicly documented; ask sales for specifics.
Features & Capabilities
What is Preemptive Exposure Mitigation (PEM) and how does IONIX deliver it?
Preemptive Exposure Mitigation (PEM) is IONIX's strategic approach to external exposure management. IONIX discovers the full external attack surface, validates which exposures are actually exploitable, and mitigates them before attackers can act. The platform operates across the CTEM lifecycle: DISCOVER, VALIDATE, PRIORITIZE, MITIGATE, VERIFY. Humans govern policy and priorities, while agentic automation operates at machine speed. Note: PEM focuses on external exposures; internal asset management is not included. Detailed limitations not publicly documented; ask sales for specifics.
How does IONIX discover unknown assets and digital supply chain dependencies?
IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, and metadata inspection, to automatically map every internet-facing asset. This includes cloud instances, third-party platforms, shadow IT, and forgotten infrastructure. The Connective Intelligence engine recursively maps digital supply chain and subsidiary risk, surfacing exposures inherited through acquisitions or partnerships. Note: Discovery is external-first and does not require agents or internal inventory. Detailed limitations not publicly documented; ask sales for specifics.
What integrations does IONIX support for incident response and remediation?
IONIX integrates with ticketing platforms (Jira, ServiceNow), SIEM providers (Splunk, Microsoft Azure Sentinel), SOAR platforms (Cortex XSOAR), and collaboration tools (Slack). Findings are automatically assigned to the right teams, and remediation workflows are streamlined through these integrations. Note: Integration with additional connectors is available based on customer requirements. Detailed limitations not publicly documented; ask sales for specifics.
Technical Requirements & Implementation
How long does it take to implement IONIX and what resources are required?
IONIX is designed for rapid deployment, with initial setup typically taking about one week. Implementation requires only one person to scan the entire network. The platform is accessible even for teams with limited technical expertise and includes comprehensive onboarding resources and dedicated technical support. Note: Implementation timelines may vary for complex environments. Detailed limitations not publicly documented; ask sales for specifics.
Security & Compliance
What security and compliance certifications does IONIX have?
IONIX is SOC2 compliant, meeting rigorous standards for security, availability, processing integrity, confidentiality, and privacy.
