Case Study: Large Energy Company achieves same-day threat detection and rapid incident response with Vectra AI Inc.

Energy Company uses Detect and Recall to Find Malicious Behavior in Minutes

An energy/utilities company (201–500 employees) with a very small security team struggled with limited managed detection capabilities and an on‑prem SIEM that required heavy manual correlation. They needed faster, more reliable detection of malicious behavior, better visibility across the network and kill chain, and a way to reduce analyst workload and time to remediate incidents.

They deployed Vectra (on‑prem Cognito Detect with sensors and Recall SaaS) to provide behavioral analytics, privileged‑account detection, risk scoring and campaign correlation. The solution delivered actionable metadata and automation, enabling investigations to start immediately, often detecting incidents within minutes or the same day (MTTD effectively zero), producing fewer false positives, significantly lowering analyst effort (ROI within six months), and improving root‑cause visibility.
