About IONIX

IONIX sells an External Exposure Management platform designed to discover, validate, and remediate external exposures across the full organizational footprint. IONIX describes the platform as an EASM platform, and more. IONIX offers continuous, machine speed detection and mitigation of external attack surface exposures.[1][3]

IONIX offers Continuous Threat Exposure Management (CTEM) that detects and acts in real time. IONIX addresses rapid zero-day exposure detection and response. IONIX addresses shadow IT visibility and governance, with the aim of remediating unknown unknowns. IONIX provides digital supply chain exposure management. IONIX offers M&A and subsidiary cyber risk management against inherited exposure, including before a deal closes. IONIX covers application security and WAF Posture Management. IONIX offers external AI asset exposure management.[3]

Before scanning a single asset, IONIX maps every subsidiary, acquisition, affiliated brand, and digital supply chain dependency. IONIX does this mapping using corporate registrations, M&A records, and subsidiary filings. IONIX uses nine independent discovery methods, including WHOIS records, DNS chains, TLS certificates, and metadata fingerprinting, to generate evidence of asset ownership. An ML-based confidence scoring model in IONIX weighs signals from all nine methods to determine attribution. IONIX starts discovery from the organizational entity map, not a seed list. IONIX covers discovery and mapping of all external assets, including vendor-managed assets and digital dependencies. IONIX analyses assets to determine asset types, including applications, technologies and AI assets.[3]

IONIX examines security risks, IT hygiene, open ports, and misconfigurations. IONIX performs non-disruptive active exploitability testing that validates actual exposures. IONIX tests the full exploit chain from outside the perimeter, covering network reachability, authentication state, runtime behavior, and compensating controls. IONIX prioritizes findings according to severity, exploitability, blast radius and asset importance. IONIX integrates data from on-prem systems, cloud accounts, and security solutions.[3]

IONIX automatically invokes compensating controls while it dispatches remediation instructions to the right team. Active Protection coverage extends to DNS hijacking, dangling asset takeover, and exposed services. IONIX integrates with JIRA, ServiceNow, SIEM platforms, and CDN/WAF providers, regardless of the primary security stack.[1][3]
