Censys Search is an enterprise subscription, available on request, that provides access to nearly the full Censys Internet Map protocol dataset for structured, at-scale internet intelligence. The subscription includes the complete certificate dataset with regex query support, CPE software version and lifecycle context for host inventory, and 31 or more days of host history. Enterprise team features include SSO via SAML, multi-user organisation access with up to 25 concurrent actions, and 10 or more export destinations.
Security operations teams use Censys Search for SOC modernisation and alert enrichment, deep application fingerprinting to identify technology across the internet, and custom asset tracking using up to 5 Collections. An MCP server enables AI-assisted workflows and tooling integration without additional development. Censys Search is available as a standalone subscription and also serves as the included search capability within Censys Core.
Internet Map Access
Censys Search provides access to almost all protocol data on the Censys Internet Map — covering services, banners, TLS details, certificates, and host attributes across the internet. The complete certificate dataset is included, with regex query support for precise filtering against certificate fields, making it suitable for both broad sweeps and targeted lookups.
Host Inventory and Context
CPE software version data and lifecycle context are applied to hosts, enabling teams to identify end-of-life software or specific technology versions at scale. Thirty-one or more days of host history lets analysts track how hosts have changed over time, useful for detecting infrastructure changes, confirming remediation, or tracing the history of a known-bad IP.
Enterprise Team Features
SSO via SAML integrates Censys Search with enterprise identity providers for centralised access control. Multi-user organisation access supports up to 25 concurrent actions, enabling team-level use without credential sharing. Ten or more output destinations allow data to flow into downstream tools, and 5 Collections support persistent asset group tracking.
AI and MCP Integration
A dedicated MCP server connects Censys Search to AI-assisted workflows, allowing analysts to query the Internet Map from within LLM-powered tooling. Alert enrichment, fingerprinting workflows, and custom tracking Collections can be triggered or extended through the MCP interface, reducing context-switching between security tools.
