Detect, analyze, and track adversary infrastructure with lightning-fast speed and precision. With Censys, threat hunters can quickly validate threats, surface hidden clusters of malicious assets, and seamlessly pivot between current and historical host indicators to accelerate hunts.

Censys
Identifies adversary infrastructure before it’s used against you
Internet-wide visibility into IPs, hosts, services, and certificates
Adversary datasets enriched with Censys intelligence
Full historical mapping of attacker infrastructure and activity
Proactive hunting workflows designed to disrupt threats early

SIEMs, EDR, Threat Feeds
Detects threats only after they appear in your environment
Limited view to only internal telemetry and logs
Static threat feeds that quickly go stale when infrastructure changes
Point-in-time detection with little context and basic insights
Reactive workflows focused on incident response

The Problem

Modern adversaries scale with reusable infrastructure, commodity hacktools, and rapid churn. IR, triage, hunters, detection engineering, and CTI need real-time Internet context to keep up.

Why It Matters

Adversaries Rapidly Churn Infrastructure

Real-time visibility and durable infrastructure traits are required to keep pace.

One Specific Signature Isn’t Enough

Hunters have to pivot from a single IOC to the broader campaign footprint.

Intel Must Become Operations

Hunters need methods for turning investigations into action.

The Censys Difference

Censys continuously observes adversary infrastructure by its durable traits.

Operationalize Internet intelligence into feeds, detections, and response actions.

Censys ARC curated threat dataset

Censys ARC tracks adversaries’ recycled infrastructure signals and reuse patterns. Search and filter by threat groups like MuddyWater, Sandworm, Volt Typhoon, Lazarus, and APT28 / Fancy Bear — with evidence tied directly to a first-party scan of the service or endpoint.

Investigation Manager

Build a node-based pivot map to document your investigation trail, visualize relationships, and track adversary infrastructure as campaigns evolve.

Signal pivoting with CensEye

Extract rare, high-signal attributes (HTTP headers, SSH banners, TLS values) and instantly see how frequently they appear across the Internet to uncover hidden related infrastructure.

Investigate suspicious open directories

Use the Open Directory Explorer and “Suspicious Directory”-labeled threats to surface web-accessible directories hosting staged payloads, hacktools, webshells, and other risky artifacts.

Historical context + live rescanning

Use certificate timelines, contextual hashes (JARM, JA3/JA4, TLSH) to connect infrastructure, spot reuse, and build investigative timelines. Run on-demand Censys Live Discovery & Live Rescan to verify behavior in real time.

Turn investigations into automated intelligence

Operationalize hunting with the Censys Adversary Investigation MCP server and Censys Assistant. Convert saved Collections into continuously updated infrastructure intelligence for your SOC workflows.
