Client Overview
A 500-bed multi-specialty hospital network with 3,000 employees and a growing digital health platform engaged SecurEpitome following a ransomware attack at a peer institution that received widespread press coverage. Hospital leadership recognized the need for a mature, continuous security monitoring capability.

Challenge
Healthcare organizations present a unique security challenge:
- Critical Systems — Patient management, ICU monitoring, pharmacy systems cannot tolerate downtime
- Legacy Infrastructure — Decades-old medical devices running unsupported operating systems
- Regulatory Requirements — NABH, DISHA framework, and India's DPDP Act
- Limited Security Maturity — Single IT administrator with no dedicated security team
The client needed a SOC that could be stood up rapidly without disrupting clinical operations, with no in-house SOC expertise to draw on.
Our Approach
Phase 1: Maturity Assessment (Weeks 1–2)
We conducted a comprehensive SOC maturity assessment using the SANS Security Operations Maturity Model (SOMM). The hospital scored Level 1 of 5 — essentially no structured security operations.
Key gaps identified:
- No centralized log management
- No network segmentation between clinical and administrative systems
- Medical devices on the same network as guest Wi-Fi
- No incident response plan
Phase 2: Architecture Design (Weeks 3–4)
SecurEpitome designed a SOC architecture optimized for healthcare constraints:
- SIEM Platform: Microsoft Sentinel (cloud-native, no on-premises hardware required)
- Endpoint Detection: CrowdStrike Falcon for Windows, alternative agent for legacy devices
- Network Monitoring: Network Traffic Analysis with Darktrace for anomaly detection
- SOAR: Sentinel SOAR playbooks for automated triage and ticket creation
Critical design decisions:
- Clinical network isolation — Separate VLAN with strict ingress/egress controls
- Medical device segmentation — IoMT devices on dedicated VLAN with deny-by-default policies
- Legacy device monitoring — Passive network monitoring (no agent) for devices that cannot accept security software
Phase 3: Implementation (Weeks 5–10)
Working with the IT team during off-peak hours (nights and weekends) to avoid clinical disruption, we:
- Deployed log collectors across 150+ Windows and Linux servers
- Configured 47 Microsoft Sentinel detection rules mapped to MITRE ATT&CK
- Developed 12 automated response playbooks (account lockout, malware quarantine, network isolation)
- Implemented 24 custom use-cases specific to healthcare threat scenarios
- Conducted a 2-day SOC analyst training program for newly hired security staff
Phase 4: Handover & Support (Weeks 11–12)
We delivered full runbook documentation, conducted tabletop exercises simulating a ransomware scenario, and provided 90 days of on-call support as the internal team matured.
Results
In the first quarter of operations, the SOC detected and responded to:
- 3 ransomware delivery attempts — All blocked at the endpoint before encryption
- 1 insider threat incident — Unusual data exfiltration by a departing employee detected and investigated
- 47 phishing attempts — Across staff email, 6 resulting in credential capture (passwords reset within 22 minutes)
| Metric | Before SOC | After SOC (Q1) | |---|---|---| | MTTD (Mean Time to Detect) | No baseline | 22 minutes | | MTTR (Mean Time to Respond) | N/A | 4 hours | | Ransomware Incidents | Unknown (undetected) | 3 (all blocked) | | NABH Security Requirements | 40% met | 100% met | | Security Incidents Escalated to Management | N/A | 4 |
Client Outcome
"We went from having one IT admin with no security tools to a fully operational SOC in 60 days. The team at SecurEpitome understood our clinical constraints and built something that works for a hospital — not just a generic enterprise."

The client subsequently enrolled in SecurEpitome's Managed Detection & Response (MDR) service for ongoing 24/7 monitoring by our analyst team.
