ot-it-convergence-challenge-for-a-manufacturing-major
A large manufacturing company faced security challenges due to distributed OT networks and complex compliance-driven connectivity needs. They needed to secure OT systems at their main plant and gradually extend protection across other global sites.
Challenges
Key pain points identified:
- No visibility into distributed OT environments.
- Limited understanding of OT-specific vulnerabilities.
- No actionable insights during cyberattacks.
- Multiple IT-OT connections, including third-party links.
The Solution
Pragya conducted site visits and audits to understand the client’s OT infrastructure and potential cyber threat landscape. Packet captures from OT systems were analyzed to detect threats and identify areas lacking basic security hygiene.
Our recommendations included:
- Deploying endpoint security on the plant workstations.
- Restricting USB access across OT environments.
- Integrating anomaly detection software with ruggedized firewalls.
This provided visibility and threat detection across physical IT and OT assets.
Outcomes
The engagement resulted in
- A complete bill of materials (BoM) for solution implementation.
- A clear scope of work for phased security rollout.
- Improved asset visibility and OT threat response planning.
The organization now had a structured path to secure its OT environments and strengthen IT-OT convergence.
