Overview

Censys offers an attack surface management platform that provides internet intelligence to security teams. The platform continuously scans the internet to discover and inventory internet-facing assets, giving organizations a complete view of their digital exposure. This helps users identify and remediate risks such as open ports, vulnerable software, and misconfigured devices. Customers include Global 2000 companies, government agencies, and security providers, and the service is sold on a subscription basis. Compared with competitors, Censys emphasizes ongoing, wide-scale internet reconnaissance to produce a comprehensive asset inventory and risk context, not just internal scans or point-in-time checks. The company’s goal is to help organizations manage exposure, reduce security risk, and improve threat detection by providing up-to-date visibility into their attack surface.
