Case Study: Oil and Gas Company achieves an AI-driven SOC and dramatic alert reduction with Palo Alto Networks Cortex XSIAM

Oil and gas company deploys AI-driven SOC with Cortex XSIAM

A U.S. oil and gas company was struggling with alert overload from a legacy SIEM that ingested few data sources and produced about a 90% false positive rate. Analysts spent excessive time manually investigating roughly 1,000 daily incidents from siloed dashboards, facing long resolution times, limited visibility, and the risk of burnout.

The company replaced its SIEM with Palo Alto Networks Cortex XSIAM, quickly onboarding more sources and applying AI-driven analytics, playbooks, and automation. Results: data ingestion rose from 800 GB/day to 1,500 GB/day and sources doubled from 10 to 20, daily flagged incidents fell to ~250 (high-priority down from ~20 to 1–2), false positives dropped to virtually none, and median time to resolution shortened from days to 59 minutes—freeing analysts for higher-value work and improving threat detection.
