What is the Censys Internet Map?

A Live, Continuously Updated Dataset of Every Device and Service on the Internet

The Censys Internet Map is the industry’s most comprehensive, up-to-date dataset of global Internet infrastructure and the foundation for our security solutions. Censys’ ML-driven scanning infrastructure continually learns the complex deployment patterns of Internet infrastructure, which it uses to track every IP, host, service, and website on the Internet in close to real time.

We enhance our data with external context, WHOIS, CVEs, and threat actor fingerprints — enabling security teams and researchers to uncover threats, track changes, and defend their Internet presence with precision.

How We Build The Internet Map

The Most Complete View of the Internet

The Censys Internet Map isn’t just a collection of raw scan data; it’s a continuously evolving, real-time representation of everything that exists on the Internet. Our technology doesn’t just find assets — it understands them, enriching each entity with context, ownership, risk profiles, relationships, and changes over time. This is how we build and maintain our Map of the Internet.

AI-driven context and relationships

Enriches data with deep intelligence on ownership, risk, and ties to threat actors.

A Living Map of the Internet – Tracking All Internet Infrastructure

More Than Scanning, We Contextualize and Understand the Internet

Beyond discovery: Understand every entity, its risks, and its potential threat

The Internet is more than just IP addresses and domains; it’s the intersection of global industry, commerce, and infrastructure. Censys curates the deepest, most contextualized map of everything connected to the Internet, helping security teams track not just their own assets and dependencies, but the infrastructure adversaries use to attack organizations.

Adversary infrastructure

Global map with illuminated nodes and arcs representing adversary infrastructure connections across the internet.
Tracking how cybercriminals mount attacks

Attackers use a complex web of servers, domains, and compromised equipment to launch and manage campaigns. Censys maps these relationships in real time.

  • Type: Command-and-control (C2) servers, phishing domains, and malware distribution sites
  • Attribution: Nation-state actors, ransomware groups, and cybercriminal networks
  • Indicators of Compromise (IOCs): TLS certificates, JA4+ fingerprints, and behavioral patterns
  • Tracking: Known adversary clusters, tactics, techniques, and procedures (TTPs)

Corporate and enterprise networks

Telecom and service provider networks

Banks, hospitals, and multinational corporations rely on complex, distributed networks, but hidden risks exist across every exposed endpoint.

  • Type: Cloud infrastructure, VPN gateways, and data center endpoints
  • Industry: Banking, healthcare, and global enterprises
  • Network providers: AWS, Google Cloud, Microsoft Azure, and major ISPs
  • Risk exposure: Unpatched servers, exposed credentials, and phishing infrastructure

Telecom and service provider networks

The digital freeways of the internet

ISPs, mobile networks, and backbone providers form the foundation of global connectivity, but misconfigurations and attacks threaten availability.

  • Type: ISP routers, 5G modems, and DNS resolvers
  • Operators: AT&T, Verizon, Cloudflare, and major backbone providers
  • Geographic reach: Global, regional, and localized network tracking
  • Impact: Connectivity disruptions and surveillance risks

Web applications and online services

The public face of the internet

From corporate websites to internal dashboards, misconfigured applications and exposed databases create significant attack surfaces.

  • Type: Content management systems (CMS), authentication portals, and cloud-based apps
  • Common technologies: WordPress, Cobalt Strike, Kubernetes, ElasticSearch
  • Risk factors: Unsecured login interfaces, outdated software, and exploitable vulnerabilities

ICS and critical infrastructure

The backbone of essential services

From power grids to water distribution, industrial control systems manage essential operations, but they’re often unsecured and exposed online.

  • Type: Human Machine Interfaces (HMI), SCADA systems, and PLC controllers
  • Industry: Water distribution, energy grids, and transportation systems
  • Location and ownership: Municipal water supplies, power plants, and government-operated infrastructure
  • Risk exposure: Misconfigured remote access, unauthenticated controls, and outdated software
