Critical infrastructure security
Critical infrastructure sites are complex operating environments. Effective security needs to account for how people, contractors, vehicles, assets and information move through the site — and how security incidents can affect safety, production and continuity.
NHN works with clients to understand the site, identify vulnerabilities, assess operational priorities and establish clear escalation pathways. Our approach goes beyond frontline guarding, with security built around the operation to protect it without unnecessarily disrupting it.
Supporting your critical infrastructure obligations
For critical infrastructure operators, security is not only about protecting a site. It forms part of a broader responsibility to identify and manage risks, build resilience and maintain the continuity of essential operations.
The Security of Critical Infrastructure Act 2018 (SOCI Act) establishes risk-management and resilience obligations for owners and operators of certain critical infrastructure assets. Depending on the asset and organisation, these can include identifying and managing material risks, maintaining a Critical Infrastructure Risk Management Program, reporting certain incidents and maintaining appropriate security and resilience measures.
11 critical industries covered by the SOCI Act
- Communications
- Energy
- Transport
- Water and sewerage
- Healthcare and medical
- Financial services and markets
- Higher education and research
- Data storage or processing
- Food and grocery
- Space technology
- Defence industry
NHN understands the operational and security environment in which critical infrastructure obligations need to be met. Our security solutions are designed to support the physical and operational controls that underpin resilience, while recognising that the operation itself still needs to function.
Security that protects operational continuity
Critical infrastructure security is about maintaining safe, reliable operations while managing risk. NHN supports clients with:
Risk assessments and advisory support
NHN can undertake security risk assessments and operational reviews to identify vulnerabilities across people, access points, assets, infrastructure and site procedures. Our recommendations are designed to be practical and site-specific, helping clients strengthen existing controls, improve preparedness and prioritise actions according to operational risk.
Protest and disruption preparedness
NHN can support planning for protest activity, activist disruption and other events that may affect site access, workforce safety, deliveries or business continuity. This can include reviewing likely scenarios, access vulnerabilities, escalation pathways and response arrangements so clients are better prepared before disruption occurs.
Emergency-aware security operations
Security personnel operate within the broader emergency and continuity requirements of the site. NHN can support clear escalation procedures, communications, access management and incident response so security activity aligns with the client’s emergency plans and operational priorities.
Security governance and reporting
NHN provides structured reporting, escalation and operational oversight to help clients understand what is happening across their security function. This can include incident trends, recurring access issues, patrol activity and emerging risks, providing more useful operational insight than simply confirming that a task or patrol has been completed.
Investigations support
Where an incident requires deeper review, NHN clients can access the Group’s investigations capability for fact-finding, incident review and specialist support. This allows frontline security issues to be examined more thoroughly where there may be broader operational, behavioural or compliance concerns.
Technology-enabled visibility
NHN can use reporting systems, dashboards and other operational tools to improve visibility across incidents, patrols, access activity and security performance. Better information helps clients identify patterns, monitor service delivery and make more informed decisions about emerging risks and security priorities.
