Censys

Censys is a cybersecurity and internet intelligence company that provides visibility into internet-connected infrastructure. Its platform continuously observes public internet hosts, services, certificates and other technical signals to help organizations understand their external attack surface. Security teams can use Censys to discover internet-facing assets, identify unexpected exposure and investigate infrastructure associated with potential threats. The company's data is also used by threat intelligence analysts, researchers and government organizations to study internet infrastructure and emerging security risks. Censys Attack Surface Management helps organizations build an inventory of external assets and monitor changes that may introduce vulnerabilities or unauthorized exposure. Its internet intelligence capabilities provide information about IP addresses, domains, certificates, protocols and services, allowing analysts to connect seemingly separate infrastructure into a broader picture. Censys also supports investigations into suspicious infrastructure and can help security teams prioritize assets that require remediation. Because organizations frequently have internet-facing systems that are not fully documented internally, external visibility can complement traditional vulnerability management and configuration inventories. Censys is particularly useful for security operations, threat intelligence and exposure management teams that need current information about the public internet. Its platform is focused on understanding what is exposed on the internet and providing data that helps organizations reduce external cyber risk.
