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.”
