External Attack Surface Management
Continuously discover exposed assets, domains, subdomains, services, technologies and misconfigurations across the external attack surface.
ThreatCanary for Critical Infrastructure
See and reduce cyber exposure across critical infrastructure.
Critical infrastructure environments connect operational systems, corporate networks, remote access, suppliers and public-facing services. ThreatCanary helps identify exposed assets, risky services, vulnerable technologies and attack paths before adversaries can exploit them.
Executive summary
Critical infrastructure organisations operate environments where cyber exposure can have real-world consequences. Energy, water, transport, telecommunications and 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.
The challenge is not only protecting internal systems. It is understanding what is exposed externally, which services are reachable, which assets are unmanaged and how internet-facing weaknesses could create 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 all expand the attack surface. Many critical infrastructure organisations also carry legacy systems that cannot be easily replaced but still need to be protected.
Security teams need practical visibility that helps them reduce exposure without overwhelming operations teams with low-value noise.
Attack surface
The attack surface
Exposed systems, identity flows, APIs, suppliers and services that attackers can inspect, probe or chain together.

Why traditional security falls short
Why traditional security falls short
Asset inventories become stale. Scanners generate noise. Manual reviews miss changes. Traditional vulnerability management may not account for operational impact or exposure context. Critical infrastructure teams need continuous external visibility and offensive validation to understand what should be fixed first.
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. It helps teams move from reactive vulnerability management to continuous exposure reduction.
Key capabilities
Key capabilities
ThreatCanary combines discovery, API intelligence, validation, reasoning and executive reporting in one operating model.
API Security
Identify exposed, forgotten or risky APIs that support digital services, customer platforms, partner integrations and operational workflows.
Shadow Asset Discovery
Find assets that are unmanaged, forgotten, supplier-hosted or outside normal inventory processes.
Exposure Validation
Move beyond theoretical vulnerability lists by validating which weaknesses are visible, reachable and meaningful.
Attack Path Reasoning
Understand how exposed assets, vulnerabilities, APIs and technologies can combine into realistic attack paths.
AI-assisted Offensive Security
Use AI-assisted reasoning to accelerate analysis, connect signals and support offensive security workflows.
Continuous Monitoring
Track external exposure as it changes over time so teams can respond before attackers take advantage.
Executive Cyber Risk Visibility
Translate technical exposure into clear reporting for CISOs, executives, boards and risk leaders.
Sector-specific use cases
