Cybersecurity for Indian Manufacturing
Indian manufacturers — auto, auto-ancillary, pharma, FMCG, steel, cement, chemicals, electronics — sit on aging plant networks that were designed to never connect to the internet, yet today are exposed via SAP, MES, vendor laptops and remote OEM diagnostics. NexaSource brings IT-grade security discipline to the OT side of the business, without breaking production.
Plant security architecture aligned to the international ICS standard
Production-safe deployment methodology — no outages during rollout
OT-aware managed SOC with ICS protocol parsers
OT / ICS security capabilities
Plant asset discovery
Passive discovery of every PLC, HMI, RTU, drive, robot, and historian using Claroty, Nozomi, Forescout, or Cisco Cyber Vision — no scanning, no production risk.
IT/OT segmentation (Purdue model)
Industrial DMZ design, firewall rules between L3/L3.5/L2, conduit definitions, and remote-access broker deployment — Palo Alto, Fortinet, Cisco firewalls.
Vendor & OEM remote access
Replace flat VPNs to plant equipment with brokered just-in-time access (Cyolo, Dispel, Claroty SRA) — full session recording and approval workflow.
OT-aware SOC monitoring
SIEM/SOAR with ICS protocol parsers (Modbus, S7, EtherNet/IP, Profinet, OPC-UA). Alerts tuned for plant rather than IT noise.
SAP, MES & ERP perimeter
SAP Solution Manager security, MES (Wonderware, GE Proficy, Rockwell FactoryTalk) hardening, and ERP-to-plant gateway protection.
Backup & recovery for plant data
Immutable backups of historian, recipe and PLC programs — designed to survive the kind of ransomware that has hit Indian auto and pharma plants.
Why Indian manufacturers come to us
- Engineers who know plants: Our OT team has implemented at auto, two-wheeler, white-goods, pharma API and bulk-drug, FMCG, and metals plants across NCR, Pune-Chakan, Chennai-Sriperumbudur and Gujarat.
- Production-safe rollout: Every architecture review starts with what cannot go down, when, and for how long. Deployments use mirror modes, weekend windows and rollback plans.
- OEM-neutral on the OT side: We work with whatever Siemens, Rockwell, ABB, Schneider, Mitsubishi, Yokogawa and Emerson equipment is on the floor — no rip-and-replace agendas.
- India-specific compliance overlay: CERT-In incident reporting for plant outages, DPDP Act for HR/employee data on plant networks, sectoral guidance for pharma, food, drug.
Threat patterns we are seeing in Indian manufacturing (2025-2026)
Ransomware on tier-2 / tier-3 component suppliers
Phobos, LockBit, Akira hitting auto-ancillary and electronics manufacturers — 1-3 days of plant downtime, OEM penalty exposure. Mitigation: external attack surface management, EDR with auto-isolation, immutable backups.
Compromise via OEM remote diagnostics
Equipment vendors with always-on VPN tunnels into plant networks — credentials stolen, entry into plant achieved. Mitigation: brokered just-in-time access with session recording.
Pharma intellectual property exfiltration
Targeting of formulation, batch records and process know-how. Mitigation: DLP fingerprinted on regulatory dossiers and recipes, USB lockdown, and behavioural anomaly detection.
Frequently Asked Questions
Will any of this disturb production?
No. All initial discovery is passive — we tap network traffic without injecting packets. Active changes (firewalls, access controls) are deployed in mirror mode first, then cut over during agreed windows.
Do you have OT engineers on staff or do you partner?
We have full-time OT engineers in NexaSource. For specialised plant-physics work or vendor-specific PLC programming we partner with the OEM (Siemens, Rockwell, ABB, etc.).
Can you handle plants outside Tier-1 cities?
Yes — we travel to plants across India for design, deployment and audit work. Routine remote operations are managed from our SOC. For ongoing on-site presence we either base engineers locally or rotate from our nearest hub.
Do we need to replace our OT equipment?
Almost never. Our default approach is to wrap, monitor and segment existing equipment. Replacement is recommended only when it is end-of-support, end-of-life or actively unsafe — and even then on a managed multi-year roadmap.
Do you cover IEC 62443 certification?
We design and operate to IEC 62443 control objectives. For formal certification we coordinate with TÜV, BSI or DNV — many of our customers begin with self-assessment maturity and certify selectively for export-critical sites.
