    Penetration Testing & Red TeamAttack Surface ManagementAsset DiscoveryVulnerability Management

    Palo Alto Networks (Expanse), now sold as Cortex Xpanse, is an external attack surface management and penetration-testing support product used to discover Internet-facing assets before an assessment begins. In the penetration testing and red team context, it helps security teams and service providers enumerate exposed hosts, map ownership, and identify unknown services and shadow IT so test scope is grounded in real external exposure. It is best for organizations that need continuous internet-scale reconnaissance to feed manual testing, red-team planning, and attack-path validation. Palo Alto Networks also offers separate consulting and testing services through Unit 42.
