We provide bulk access to the data that powers Censys for
both enterprise customers and approved non-commercial researchers. These datasets
contain curated, labeled data that describe IPv4 hosts, websites, and
certificates, as well as what we have found in historical scans.
For commercial information, please
contact our sales team. To apply for
research access, please see Research Access to Censys
Data.
We also publish the raw handshakes from our horizontal
Internet scans. These data files contain the ZMap or ZGrab JSON output for
the scan of a single port or protocol. For example, JSON encoded transcript
of a TLS handshake with every IPv4 host on TCP/443.
We provide access to last month's data for all Censys users.
Our most recent scans and historical records are available to
confirmed researchers and enterprise customers. For commercial information,
please contact our sales team. To

to Censys Data.
