TL;DR: India's CEA cyber regulations make proof of asset visibility, monitoring and incident reporting the hard part of compliance, according to Nozomi Networks. OT governance will need live evidence of control execution, not just documented policy.
Editorial analysis by NHI Mgmt Group, based on content published by Nozomi Networks: “India's New CEA Cybersecurity Regulations: What Power Sector Leaders Need to Know Before April 2027”.
Key questions
Q: When should power operators prioritise asset visibility over new security tooling?
A: They should prioritise visibility first when they cannot confidently answer what assets exist, how they communicate or which systems are externally reachable.
Q: What do security teams get wrong about vendor risk in critical infrastructure?
A: They often treat vendor assurance as a procurement step instead of an ongoing control.
Q: What breaks when power-sector OT is not isolated from corporate networks?
A: When OT shares trust paths with corporate IT or external parties, the operator loses the ability to contain compromise to a narrow segment.
Practitioner guidance
- Build a live OT asset register Capture devices, firmware, protocols, communication paths and external connections in a continuously updated inventory that can stand up to audit and incident review.
- Separate remote access from default trust Require hardened logical separation, approval workflows and continuous monitoring for any connectivity between corporate IT, vendors and OT networks.
- Embed supplier controls into contracts Require patches, recovery procedures, bills of materials, lifecycle information and vulnerability disclosure obligations in every critical service agreement.
Bottom line: India's power-sector regulations turn cybersecurity into an operational and governance obligation across IT, OT, vendors and reporting chains.

Governance is now an operational control, not a policy artefact: the CEA framework makes power-sector cybersecurity measurable through registers, approvals, monitoring and reporting. That matters because many security programmes still treat governance as documentation, while operational environments require evidence that trust boundaries, remote access and vendor exposure are actively controlled. The organisations that struggle will be the ones that cannot turn policy into repeatable enforcement.
A question worth separating out:
Q: Who is accountable when compliance evidence is incomplete?
A: Accountability should sit with the control owner, the system owner, and the governance function that defined the evidence standard. If those roles are unclear, compliance becomes a reporting problem instead of a control problem, and audit findings become harder to resolve.
