External Attack Surface Management
Continuously discover exposed assets, domains, subdomains, services, technologies and misconfigurations across essential service environments.
ThreatCanary for Critical Infrastructure
Protect essential services from exposed attack paths.
Critical infrastructure providers operate environments where cyber exposure can become operational risk. ThreatCanary helps security and operations teams discover exposed assets, validate reachable weaknesses and prioritise the attack paths most likely to affect essential services.
Executive summary
Critical infrastructure organisations operate environments where cyber exposure can have real-world consequences. Energy, water, transport, telecommunications, logistics, ports, utilities and other essential service providers often manage a mix of operational technology, corporate IT, remote access, supplier systems, legacy infrastructure, cloud services and public-facing digital platforms. In Australia, SOCI Act risk management obligations make externally visible exposure, supplier pathways and operational resilience evidence board-level concerns.
The risk is not limited to the control network itself. Attackers look for reachable services, exposed remote access, forgotten assets, supplier pathways, unmanaged cloud systems, weak identity boundaries and public-facing applications that can become stepping stones toward operational disruption.
ThreatCanary helps critical infrastructure teams continuously understand what is externally visible, what is exploitable, which paths matter and which fixes reduce operational risk fastest.
Protected essential services
Protect the systems communities depend on.
ThreatCanary helps critical infrastructure teams understand which exposed services, supplier paths, remote access points and vulnerable technologies could become operationally meaningful attack routes.
Critical infrastructure attack surface
Essential services depend on connected infrastructure, suppliers and access paths.
ThreatCanary maps externally visible assets, remote access, supplier-facing systems, cloud dashboards, APIs and OT-adjacent services into one exposure model so teams can see how small gaps combine into operational risk.

Sector challenge
The sector challenge
OT and IT environments are increasingly connected. Remote access, third-party maintenance, cloud dashboards, public portals and supplier integrations can expand the attack surface faster than traditional inventories can keep up.
Many essential service environments also carry legacy systems that cannot be easily replaced. Security teams need to reduce exposure without creating operational disruption or overwhelming engineering teams with low-value scanner output.
The practical challenge is prioritisation: understanding which internet-facing weaknesses, exposed technologies and access paths could realistically create operational impact.

Why traditional security falls short
Why traditional security falls short
Asset inventories become stale. Vulnerability scanners generate noise. Manual reviews miss change. Periodic assessments may not reflect the current state of public exposure, supplier access, cloud services or operationally sensitive systems.
Traditional vulnerability management often treats findings as isolated technical issues. Critical infrastructure teams need context: reachability, exploitability, dependency, operational relevance and whether multiple small exposures can chain into a meaningful path.
How ThreatCanary helps
ThreatCanary continuously discovers external assets, profiles visible technologies, identifies risky services, validates exposure and supports prioritisation based on exploitability and operational relevance.
The platform connects EASM, API security and AI-native offensive validation so teams can understand the difference between theoretical exposure and practical attack paths that could affect essential service operations.
Findings are backed by evidence that can be reviewed, reproduced and translated into remediation priorities for security, operations, engineering and executive stakeholders.
Operational exposure model
From exposed service to operational consequence.
Critical infrastructure risk often starts outside the plant or control network: an exposed portal, supplier pathway, weak access boundary or forgotten service that can be chained toward operational impact.

Direct answers on scope, evidence, safety controls and how ThreatCanary differs from tools you already run.
01How does ThreatCanary help critical infrastructure operators reduce external exposure?
ThreatCanary helps critical infrastructure operators discover internet-facing assets, remote access services, supplier-maintained systems, cloud dashboards, APIs and misconfigurations, then validates which weaknesses are reachable and relevant to essential service operations.
02Can ThreatCanary support OT and IT exposure management?
ThreatCanary focuses on externally visible and OT-adjacent exposure such as remote access, supplier pathways, cloud services, public portals and identity boundaries. It helps teams understand where IT, supplier and operational dependencies create realistic paths to operational risk without flooding engineering teams with low-value scanner noise.
03How does ThreatCanary help prioritise risks to essential services?
ThreatCanary prioritises risks by validating exploitability and connecting findings to operational relevance, affected assets, supplier context, attack paths and evidence. This helps critical infrastructure teams focus on exposure that could plausibly affect essential service continuity.
04How does ThreatCanary support SOCI-related cyber risk visibility?
ThreatCanary does not provide legal compliance advice, but it can support SOCI-related cyber risk conversations by producing evidence of external exposure, validated weaknesses, supplier-facing risk, remediation progress and attack paths that may affect critical infrastructure resilience.
