About Censys
Censys continuously scans the entire internet to discover and inventory all external-facing digital assets, including hosts, services, and websites. This data powers its Attack Surface Management (ASM) and Threat Intelligence products. The ASM platform helps organizations visualize their entire external footprint, identify shadow IT, and manage security risks like open ports and expired certificates. Its Threat Intelligence capabilities allow security researchers and analysts to hunt for threats, investigate incidents, and enrich security data with real-time context about internet-connected devices. Censys serves enterprises, government agencies, and security researchers who need comprehensive visibility into their internet presence and the global threat landscape.
