Access and privacy
Access: Account required
The legacy free search has been retired; use the current Censys Platform and its account-based access.
Privacy sensitivity: Moderate
Infrastructure queries may be sensitive. Review scope and minimize unnecessary lookups.
Responsible use
- Prefer passive sources (certificate logs, historical DNS, reputation databases) before anything that touches the target directly.
- Record the date of every lookup — DNS, hosting, and WHOIS data change often.
- Port or vulnerability scanning is not passive research; only do it with written authorization.
