Use Case: Securing a Manufacturing Enterprise Across IT & OT Environments

📌 Client Overview:
A fast-growing manufacturing company operating multiple plants across India and internationally. Their production depends on both traditional IT systems and OT (Operational Technology) like SCADA, PLCs, and IIoT devices for real-time operations.

🚨 Business Challenges

⚠️ 1. OT-IT Segmentation Gaps

• Inadequate segmentation between IT and OT networks increased cyber risk to production systems
• No centralized visibility into OT-specific threats or anomalies

🧪 2. Endpoint & Server Threats

• Endpoints were vulnerable to USB-based threats, ransomware, and fileless malware
• Legacy AV solutions lacked behavior-based threat detection

📡 3. Lack of Unified Monitoring & Threat Detection

• No SIEM or analytics tools to detect abnormal behavior across systems
• No centralized logging from firewalls, switches, or OT controllers

⚖️ 4. Compliance & Audit Challenges

• Difficult to align with standards like ISO 27001, NIST CSF, and customer security audits
• Audit trails and logging were either manual or missing

✅ Our Solution

We designed a layered cybersecurity framework that protected IT and OT infrastructure, enhanced endpoint security, and enabled centralized monitoring and compliance reporting.
