## About
Censys builds the most complete and reliable map of the internet so security teams can see every exposed asset and close gaps before attackers do. Their platform continuously scans and indexes every IP address and domain, giving teams an always-current view of what’s actually out there. Security operations groups use the data to find unknown assets, track shadow IT, and monitor changes across their attack surface. Threat hunters rely on the same dataset to spot new infrastructure tied to campaigns or malware. Because the data is refreshed daily and includes historical snapshots, analysts can see how exposures evolve over time. Censys serves mid-market and enterprise security teams that need more context than basic port scans provide. The company’s search interface lets users query by protocol, certificate, software version, or geographic location without writing custom scripts. Integrations with existing SIEM and SOAR tools make it easy to pull the intelligence into daily workflows. Censys also offers an attack-surface management product that automatically discovers and prioritizes risks. Customers range from financial services firms protecting customer data to technology companies defending large cloud footprints. The service is delivered as a SaaS platform with tiered access based on query volume and API usage. No on-premise installation is required.
