About Censys

Censys describes its Platform as the one place to understand and act on everything on the Internet.

The Censys documentation says the Platform has API endpoints that enable integration of Platform functionality with a tech stack. It also says Platform SDKs are available. One of the documented advantages is querying across all asset types with one API search query instead of running multiple endpoints for each asset type.[4]

The home page says Censys ARC is actively tracking php2shell exposures. That menu gives its mission as to illuminate Internet behaviors that impact our world. The Censys Partner Program offers opportunities to expand reach, with support from Censys at every step.

The documentation lists SAML Authentication and SCIM Configuration.[4][5]
