Cybersecurity for the factory floor — without breaking the line.
Macksofy delivers OT/ICS security assessments, IT-OT segmentation reviews and IEC 62443-aligned programmes for India's manufacturing, automotive, pharma, oil & gas and discrete-process clients. Assessments designed to find what attackers will — without disrupting production.
- Passive OT discovery — full asset inventory without sending a single active packet into the control network
- IT-OT segmentation review with concrete remediation steps the OT team can sequence into a planned shutdown
- IEC 62443-aligned controls programme — zone & conduit model, security level targets, gap-closure roadmap
- OT-aware SOC content — Modbus / DNP3 / OPC anomaly detection, vendor-remote-support session correlation
- Production-continuity-aware ransomware drills
Why Manufacturing · OT cybersecurity isn't generic.
Indian manufacturing has spent the last five years collapsing the gap between IT and OT — MES connecting to ERP, OEE dashboards pulling PLC telemetry, factory WiFi extending into the control room. The result: an attack surface that didn't exist when the OT network was a true air-gap. Recent ransomware events at Indian auto OEMs and pharma majors have made cybersecurity a board-level conversation on the OT side of the house.
Macksofy's OT practice covers: IT-OT segmentation review, ICS / SCADA / PLC security assessments, IEC 62443-aligned controls programmes, OT-aware Managed SOC (Wazuh + agentless OT collectors), and ransomware-readiness drills with production-continuity playbooks. We work alongside the OT integrator, not against them — most engagements have a Honeywell / Siemens / Rockwell / Yokogawa partner in the loop.
What's specific to OT cybersecurity: no active scanning into the OT network (passive only), maintenance-window-aware testing, vendor coordination with the OT OEM, and a reporting style that controls-engineers and process-safety folks actually read.
Frameworks Macksofy already maps to.
Every engagement's controls matrix tracks against these frameworks so the same evidence covers multiple regulator submissions.
- IEC 62443 — Industrial automation & control systems security
- CERT-In sectoral CSIRT (for critical-information-infrastructure)
- NCIIPC — National Critical Information Infrastructure Protection Centre
- MeitY CERT-In CSIRT-Power / CSIRT-Manufacturing alignment
- OEM advisories (Siemens, Schneider, Rockwell, Honeywell, Yokogawa)
- ISO 27001 + ISO 27019 (energy-sector controls)

What a Manufacturing · OT engagement actually delivers.
Mid-size auto-component manufacturer · 4 plants · Maharashtra + Gujarat + Tamil Nadu
Passive OT discovery across 4 plants. IT-OT segmentation review. IEC 62443 zone & conduit baseline. Quarterly OT-aware vulnerability digest. Ransomware-readiness drill with the plant-leadership team.
Discovery surfaced 380+ OT assets the IT team didn't know existed — including 22 PLCs with default credentials and 9 engineering workstations dual-homed to IT and OT. One plant's MES had an outbound internet path the segmentation diagram showed as blocked.
Default credentials rotated, dual-homed workstations migrated to a hardened jump-host model, MES outbound path closed and verified via passive sensor. IEC 62443 baseline locked in as the standard for new line commissioning.

“We've worked with three Big 4 firms before Macksofy. None found what their team did in our payments stack. The most actionable report we've received in a decade.”
“The CHFI training Macksofy delivered for our cyber cell raised investigation quality measurably. Practical, India-context-aware, and respectful of our operational realities.”
“Came in with zero security background. 5 weeks later I was running Burp Suite and Metasploit confidently. Cleared CEH on the first attempt.”
