How Censys protects critical infrastructure defenders

Industrial Protocol & Vendor Fingerprinting

Identify externally reachable services — including industrial control protocols and remote access interfaces — so teams can prioritise the highest-risk control surfaces across distributed OT environments.

HMI Screenshot Validation

Automatic screen captures from exposed human-machine interfaces show exactly what an attacker would see — providing clear, visual proof of exposure to support remediation decisions.

Adversary Infrastructure Tracking

Censys ARC research labels and tracked threat infrastructure let teams hunt for ransomware and targeted campaigns, then pivot across related hosts, certificates, domains, and services to build out investigations from a single indicator.

Compliance-Ready Exposure Reporting

Generate reporting aligned to NERC CIP, NIST SP 800-82, IEC 62443, and NIST CSF — producing audit-ready evidence for resilience reporting and executive risk oversight.

SIEM, SOAR & AI Integrations

Feed findings into SIEM, SOAR, and threat intelligence platform workflows, and power AI-driven operations via the Censys Assistant and MCP server — so context reaches the tools and AI copilots teams already rely on.

How It Works

Detect

Censys scanning identifies externally reachable industrial protocols, remote access interfaces, and internet-exposed ICS and OT devices across distributed SCADA and critical infrastructure environments — prioritising the highest-risk exposures by external reachability.
Confirm

Automatic screenshot capture of human-machine interfaces shows exactly what an attacker can see when they find an exposed device — establishing exposure scope and visual context without requiring physical site access or coordination with OT operations teams.
Track

Adversary infrastructure tracking through Censys research labels enables teams to follow threat actor campaigns targeting industrial sectors — pivoting across hosts, certificates, and domains tied to known threat groups that target critical infrastructure operators.
Report

Generate audit-ready asset inventories and continuous monitoring evidence aligned to critical infrastructure compliance frameworks including NERC CIP, NIST SP 800-82, IEC 62443, and NIST CSF — satisfying both regulatory requirements and board-level risk reporting needs.
