Protect Your Factory Floor, SCADA & Supply Chain

A ransomware infection on a PLC or SCADA system can halt production for weeks. As Indian factories embrace Industry 4.0 — connecting OT systems to IT networks and the cloud — the attack surface grows dramatically. Ogma secures the intersection of IT and OT.

The Industry 4.0 Security Problem

OT/IT Convergence

Connecting PLCs, SCADA, and MES to enterprise IT networks (for ERP integration, remote monitoring) collapses the air gap that used to protect factory floors. What was isolated is now exposed.

Unpatched Windows-Based SCADA

Most SCADA and HMI systems run on Windows XP, Windows 7, or Windows Server 2008 — end-of-life OS that cannot be patched without disrupting production. A single exploit can shut the line.

Remote Vendor & OEM Access

Equipment vendors (often foreign OEMs) require remote access to PLCs for maintenance. This creates persistent VPN connections that bypass your security controls entirely.

Ogma's OT/IT Security Architecture

OT Network Segmentation (FortiGate)

Implement Purdue Model segmentation — isolating Level 0-2 (field devices, PLC, SCADA) from Level 3 (MES) and Level 4-5 (enterprise/cloud) with industrial-grade FortiGate firewalls.

Windows SCADA Endpoint Security

CrowdStrike Falcon deployed on SCADA workstations and HMI systems — even those running legacy Windows. Blocks ransomware and malware without requiring OS updates or disrupting production.

Secure Remote OT Access (Cato ZTNA)

Replace dangerous always-on VPN connections for OEM vendors with Zero Trust access. Vendors get time-limited, session-recorded access to only the specific PLC or system they need.

OT Network Monitoring

Passive monitoring of OT traffic using protocol-aware sensors that understand Modbus, DNP3, OPC-UA, and PROFINET. Detect anomalies without disturbing production systems.

Supply Chain Security

Assess and secure third-party supplier and vendor access. Implement supplier risk scoring and automated access controls — critical for PLI scheme factories under government scrutiny.

OT Incident Response

Pre-built OT-specific incident response playbooks. When production stops due to a cyber incident, every minute costs money — Ogma's IR team is trained specifically for OT environments.

Frequently Asked Questions

Yes. Our approach uses passive monitoring and network-level controls (firewalling, segmentation) that do not require agents on PLCs or PLC reboots. For Windows-based SCADA/HMI, CrowdStrike can be deployed in sensor-only mode initially, adding protection without impacting operations. Network changes are implemented during planned maintenance windows.

CERT-In and multiple government advisories have flagged concerns about embedded backdoors and undisclosed remote access capabilities in some Chinese-origin industrial equipment. Ogma conducts network traffic analysis on equipment from flagged vendors, implements strict egress controls, and segments Chinese-origin OEM systems from the broader network as a risk mitigation measure.

PLI schemes don't mandate specific cybersecurity standards directly, but several sector-specific regulations (electronics, pharma, defence) increasingly require ISO 27001 or IEC 62443 compliance. Additionally, many global customers and export requirements (US, EU) mandate demonstrable OT security controls. Ogma can help achieve and document these compliance requirements.
