Case Study: Kirby Corporation achieves 99.7% alert reduction and saves 10–15 hours/week with Critical Start

Maximize efficiencies with CRITICALSTART MDR

Kirby Corporation, facing a small IT staff and severe alert fatigue, engaged Critical Start for managed detection and response using its Zero-Trust Analytics Platform (ZTAP), Trusted Behavior Registry and mobile app to maximize efficiency and offload routine triage. The goal was to reduce noise, speed incident handling, and avoid building a large in-house SOC.

Critical Start implemented Tier‑1 and Tier‑2 triage, integrated Kirby’s SIEM and endpoint sources (5–6k user nodes and ~1k servers), and provided analyst support via ZTAP and the mobile app; the service reduced roughly 584,000 of 589,000 quarterly security events so only about 1,400 alerts reached Kirby (a 99.7% reduction), saved the team an estimated 10–15 hours per week, accelerated time‑to‑action, and cost roughly one‑fifth of building equivalent internal capability. Critical Start’s quick onboarding, continuous tuning, and analyst availability delivered measurable efficiency and operational savings for Kirby Corporation.
