Case Study: Major U.S.-Based Tech Company achieves accurate automated attack-surface discovery and streamlined M&A security with Palo Alto Networks Cortex Xpanse

Why a Major U.S.-Based Tech Company Chose Cortex Xpanse over RiskIQ

A major U.S.-based Fortune 1000 tech company needed to identify, monitor, and secure a large and changing internet-facing footprint—especially assets from frequent acquisitions. After three years with RiskIQ, the SOC found the data stale, port- and domain-based scans insufficient (they needed service- and certificate-level visibility), and the workflow overly manual and limited by seat constraints.

The company moved to Cortex Xpanse for protocol-validated scanning, certificate analysis, and stronger cloud discovery, gaining automatic, high-confidence inventories of services and accurate attribution across multitenant environments. As a result the SOC automated attack-surface reduction, accelerated M&A cyber due diligence and integrations, cut false positives and manual verification, and empowered the broader security team to proactively find and remediate high-risk public-facing services.
