Case Study: Largest Electric Utility Company achieves 30% alert reduction and 1 FTE savings with Palo Alto Networks Cortex XSOAR

Largest Electric Utility Company - Customer Case Study

One of the largest electric utility companies in the US struggled with an overwhelmed SOC: a high volume of alerts from diverse sources (SIEM, vendor tools, open source and in‑house solutions) produced many duplicate incidents, required analysts to pivot between screens and manually copy information, and made monthly case reporting slow and error‑prone—reducing time for threat hunting and data‑driven decision making.

The SOC deployed Cortex XSOAR playbooks to deduplicate alerts, orchestrate workflows and ticketing, correlate threat intelligence, and automate case metrics and reporting. Within a month alert/case volume fell by about 30% (roughly one full‑time analyst worth of time saved), enabling more aggressive detection without increasing analyst workload, speeding monthly audit reporting, improving enrichment and analyst productivity, and surfacing new insights for training and defense planning.
