The Problem

Critical infrastructure disruptions increasingly begin with external exposures — that never appear in inventories. Most teams invest heavily in premium in-network security, but rely on “good enough” OSINT for the external view.

Why It Matters

External Exposure Drives Disruption

Untracked remote access and reachable control surfaces create OT risk that inventories miss.

Outside-In Visibility Completes the SOC

Enrich triage and IR with proof of what’s reachable and what changed externally.

Track Threats, Reduce Exposure

Hunt adversary infrastructure targeting OT systems, then operationalize results as feeds.

The Censys Difference

Censys maps the entire public Internet — your external attack surface and adversary infrastructure alike.

This visibility supports multiple security workflows. Exposure management to incident response and threat investigation.

Industrial protocol + vendor fingerprinting

Identify externally reachable services (including common industrial protocols and remote access interfaces) so you can prioritize high-risk control surfaces across distributed environments.

HMI screenshot validation

See what attackers see via automatic screen captures from common remote interfaces, giving you definitive proof of exposure for response and remediation.

Censys ARC adversary infrastructure tracking

Leverage Censys ARC’s tracked infrastructure and research-driven labels to hunt for ransomware and targeted activity, then pivot through related hosts, certificates, domains, and services to expand investigations beyond a single indicator.

Compliance-ready exposure reporting

Generate evidence and reporting aligned to critical infrastructure programs and frameworks like NERC CIP, NIST SP 800-82, IEC 62443, and NIST CSF to support audits, resilience reporting, and executive risk oversight.

Integrations for SIEM/SOAR, TIP, and AI

Operationalize findings across SIEM/SOAR and TIP workflows, and power AI modernization using the Censys Assistant and MCP server. Context flows into the tools and copilots your teams already use.
