Industry & Scope
Industry :
Power Manufacturing & Generation
Organization Type :
Large Commercial Bank
Deployment Size
20,000
Geography :
Pan-India (Thermal, Hydro, Solar plants, substations, R&D and service centers)
Security Solutions Deployed:
- FortiSRA – Secure Remote Access
- Forti Authenticator – MFA
- Fortinet OT Firewall – FortiGate with FortiGuard OT Security
- TXOne Stellar EDR – OT Endpoint Detection & Response
Executive Summary
A leading Indian power manufacturing enterprise required a secure, scalable, and OT-safe cybersecurity architecture to protect critical production facilities distributed across India. The organization faced increasing ransomware risk, uncontrolled vendor access, and lack of endpoint protection on OT systems. The solution integrated Fortinet’s OT network security and identity platform with TXOne Stellar EDR, delivering defense-in-depth OT security without impacting operational uptime.
Business Challenges
- – Geographically dispersed OT environments
- – Legacy PLC, SCADA, and DCS systems
- – Insecure vendor and OEM remote access
- – Lack of OT-aware endpoint protection
- – Compliance and audit requirements
Security Objectives
- – Secure OT networks without disrupting operations
- – Implement Zero-Trust remote access
- – Enforce centralized MFA
- – Deploy OT-specific endpoint protection
- – Enable centralized monitoring across India
Solution Overview
Fortinet OT Firewall provides network segmentation, deep OT protocol inspection, and virtual patching. FortiSRA delivers Zero-Trust secure remote access with session recording and audit logging. FortiAuthenticator enforces centralized identity, MFA, and role-based access control.
TXOne Stellar EDR protects OT endpoints with behavior-based detection, ransomware protection, and application allowlisting designed for industrial environments.
Deployment Phases
- Phase 1: OT risk assessment and pilot deployment
- Phase 2: Core Fortinet security rollout
- Phase 3: TXOne Stellar EDR endpoint protection rollout
- Phase 4: Forti Authenticator Roll out
Business Outcomes
- – 100% OT asset visibility across plants
- – >90% reduction in vendor access risk
- – Faster detection and response to cyber threats
- – Zero production downtime during deployment
- – Improved compliance and audit readiness
Conclusion
The combined Fortinet and TXOne OT security architecture enabled the power manufacturing organization to achieve comprehensive OT cyber resilience, secure remote access, and long-term operational stability across all India locations.
