Cortex Xpanse

Cortex Xpanse is an automated attack surface management platform developed by Palo Alto Networks designed to help enterprises continuously discover, evaluate, and mitigate internet-facing security exposures. It operates from an outside-in attacker perspective, systematically indexing the entire global internet IPv4 and IPv6 space to detect managed and unmanaged assets associated with an organization. Core technical capabilities include automated cloud asset attribution, shadow IT identification, active vulnerability scanning, misconfiguration detection, public port mapping, and continuous threat exposure monitoring. By cataloging an organization's digital footprint dynamically, security teams gain actionable visibility into internet-connected servers, cloud instances, SaaS environments, and external supply chain endpoints.

The platform is delivered as a cloud-native software-as-a-service solution that requires no agents, local sensors, or initial network credentialing to conduct discovery operations. It integrates natively with Palo Alto Networks Cortex platforms including Cortex XSOAR for automated playbook-driven remediation, Cortex XDR for deep endpoint and network correlation, and Prisma Cloud to reconcile discovered unmanaged cloud assets against configured cloud service provider accounts across AWS, Microsoft Azure, and Google Cloud Platform. Additionally, Cortex Xpanse interfaces seamlessly with enterprise SIEM, SOAR, and IT service management systems such as ServiceNow and Jira to automate remediation tickets and streamline cross-functional incident handling workflows.

Common enterprise use cases include active attack surface management, shadow IT discovery, subsidiary and merger-and-acquisition asset mapping, supply chain vulnerability tracking, and automated exposure reduction. By replacing static and periodic external vulnerability scans with real-time discovery and remediation playbooks, Cortex Xpanse helps security operations centers drastically reduce the mean time to discover and remediate high-risk exposures such as open administrative protocols, exposed database instances, and unpatched software services across complex multi-cloud and hybrid IT environments.
