IONIX vs Palo Alto Cortex Xpanse
Breadth scans everything. Depth proves what attackers can exploit.
Cortex Xpanse scans 500 billion ports a day and starts from internet-visible assets. IONIX builds a complete organizational entity model, then validates which exposures an attacker can reach and exploit, across subsidiaries and supply chain.
Most organizations are aware of only about 62% of their real attack surface.

Xpanse starts from internet-visible assets and scans at massive port scale. It does not run structured organizational research to build a complete entity model first, so unattributed assets, acquired entities, and shadow infrastructure fall outside the picture. Buyers inherit blind spots in the exact places attackers look.
IONIX builds the organizational entity model before it scans. Multi-factor discovery and ML attribution map owned assets, vendor-managed assets, and digital supply chain dependencies into one accurate inventory. You scope your program against your real surface, not just the ports a scanner happened to reach.
Validated, not discoveredAct on confirmed exploitability, not theoretical risk
Xpanse risk scoring blends CVSS with KEV and EPSS, but it does not lead with validation and does not confirm live exploitability. Severity stays theoretical, and teams still triage long lists of potential exposures. The work of proving what an attacker can actually reach lands back on your analysts.
IONIX runs non-intrusive exploit simulation to confirm what is reachable and exploitable from the outside, the way an attacker would test it. Validation gates prioritization, so teams act on proven risk. Customers see a 97% drop in false positives and a 90% reduction in MTTR.
Specialist, not add-onA purpose-built platform that works with any stack
Cortex XDR 5.0 added a Unified Exposure Management module pitched as eliminating the need for standalone EASM tools. An XDR add-on does not replicate external-first discovery depth, validated exploitability, or supply chain and subsidiary coverage, and it delivers most of its value inside the Cortex stack. For mixed or non-Cortex environments, that is lock-in dressed as consolidation.
IONIX is a purpose-built external exposure platform that integrates with any security stack through APIs, with no agent or specific vendor deployment required. You get depth in external exposure plus Active Protection against asset takeover, independent of your endpoint, SIEM, or cloud choices. Attackers exploit new CVEs within hours, so depth and independence are not luxuries.
Mitigation, not managementMitigate at machine speed, not at platform pace
Xpanse reports exposures and scores them. Closing them falls to your team and the rest of the Cortex stack. The gap between a finding and a fix is where breaches start, and attackers move within hours of disclosure.
IONIX closes the loop. Live Exposure Defense puts a 12-hour SLA on the path from CVE publication to validated, exploitable exposure, then recommends specific WAF rules ready to deploy through Akamai, Cloudflare, AWS, Azure, and other supported vendors. Active Protection goes further, automatically claiming dangling domains and abandoned cloud assets before attackers reach them. Humans govern, agents operate.
