The Problem

After a near-miss ransomware incident, Helios discovered their mean time to detect threats exceeded 4 days. IT and OT networks were flat, logging was fragmented, and compliance findings were piling up.

The Solution

RippleCode deployed a managed 24×7 SOC: Microsoft Sentinel SIEM with curated detections, CrowdStrike EDR across 3,800 endpoints, OT network segmentation and passive monitoring, plus an incident-response retainer with quarterly purple-team exercises.

Architecture

  • Microsoft Sentinel SIEM with 240+ tuned detection rules
  • CrowdStrike Falcon EDR fleet-wide
  • IT/OT network segmentation with passive OT monitoring
  • SOAR playbooks automating tier-1 triage
  • Compliance evidence automation for NERC-aligned controls

ROI

Cyber-insurance premiums dropped 22% and audit findings cleared within two quarters — while avoiding even one ransomware event protects an estimated $12M in operational risk.

The purple-team exercises proved the SOC works — simulated attacks were caught in minutes. Our board finally sleeps at night.
