How Indian Enterprises Are Rethinking Cybersecurity in 2025: Zero-Trust and OT Security

The End of Perimeter Security

The traditional castle-and-moat security model is obsolete in a world of remote work, cloud services, and IoT-connected factory floors. Indian enterprises are rapidly shifting to zero-trust architectures.

Zero-Trust in Practice

• Identity-centric access — every user and device must authenticate regardless of location
• Microsegmentation — isolate production OT networks from corporate IT
• Continuous verification — re-authenticate at every access request, not just at login
• Least-privilege access — employees and systems get only the minimum access they need

AstraCMITS conducts OT security assessments and implements network segmentation that meets GMP requirements for validated computerised systems.
