TL;DR: Hong Kong’s Protection of Critical Infrastructures Bill, effective January 1, 2026, requires operator-level accountability, continuous monitoring, formal risk assessments, and supplier oversight across critical sectors, according to SecurityScorecard. The compliance burden is increasingly about proving control over external dependencies, not just documenting internal security posture.
Editorial analysis by NHI Mgmt Group, based on content published by SecurityScorecard: “How to Prepare for Hong Kong’s Protection of Critical Infrastructure Bill in 2026”.
Key questions
Q: Where does supplier governance fail in critical infrastructure programmes?
A: Supplier governance fails when external access is treated as a procurement issue rather than a controlled access path.
Q: Why do external dependencies create regulatory risk for critical services?
A: External dependencies create regulatory risk because responsibility does not end at the operator’s perimeter.
Q: What are the signs that vendor oversight is not working?
A: Look for vendors with unclear owners, dormant accounts, duplicate access paths, expired approvals, unresolved exceptions, and reassessment cycles that do not change permissions.
Practitioner guidance
- Map supplier access paths to critical services Inventory every cloud, managed service, and vendor connection that can reach regulated workloads, then assign an owner and business purpose to each path.
- Require evidence for continuous monitoring Define what monitoring outputs count as compliance evidence, including alerting, reporting cadence, and escalation records for external dependencies.
- Review standing privilege for external identities Find vendor accounts, service accounts, and delegated roles that retain persistent access, then set review and removal criteria for each one.
Bottom line: Hong Kong’s bill turns supplier oversight into an operational requirement for critical infrastructure operators, not just a contractual expectation.

Supplier governance is now an identity problem, not only a procurement problem. Once a critical infrastructure law requires oversight of external dependencies, the weak point is often the access path itself. That means delegated administration, service accounts, and vendor-issued credentials become governance objects, not just technical artefacts. The practical conclusion is that supplier assurance must include identity ownership, privilege scope, and offboarding evidence.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should security teams respond when critical infrastructure rules extend to third parties?
A: Security teams should expand governance to include external identities, privileged supplier connections, and evidence-ready monitoring. That means defining access ownership, proving offboarding, and aligning reporting to regulatory obligations. The aim is not simply more controls, but a demonstrable chain of accountability across the dependency landscape.
