What is CensysInspectBot?

CensysInspectBot belongs to Censys's internet-wide scanning activity. Censys probes public addresses and ports to identify exposed services and record what they return. For HTTP and HTTPS, its scanner requests /, follows local redirects, and can make more requests to classify the application it found.

That pattern differs from a conventional content crawl. A Censys request may be one step in examining a network service, not an attempt to follow all links or read a publication. Censys also says its scanners do not try to sign in, reach databases, or obtain authenticated access.

The observations feed Censys datasets used for internet measurement and security work. Censys does not document an AI answer product or a model-training purpose for this scanner. Blocking it can stop new Censys observations of a service, but it does not change the site's eligibility for AI search.

The current official HTTP identity is CensysInspect/1.1. That does not exactly match the CensysInspectBot token retained in this bot. Check the full header and compare the source with Censys's current scanner networks before assigning the traffic, since either user-agent name can be copied.

Not relevant for AI search

Is CensysInspectBot relevant for AI search?

No. CensysInspectBot is not part of AI search or training, so allowing or blocking it does not change your AI visibility.

CensysInspectBot runs synthetic monitoring or uptime checks on a schedule. It is not collecting content for any index or model, so it has no bearing on search rankings or AI answers. You usually see it because your own team or a service you use set up a check.

How to handle CensysInspectBot

Censys's current opt-out instructions use firewall rules for its published scanner subnets and ASNs. A user-agent filter can reject HTTP requests, but it cannot prevent the scanner from connecting to other exposed services.

The directory carries a positive robots flag, and the current HTTP identity provides a stable token for this robots.txt request:

User-agent: CensysInspect
Disallow: /

Censys does not present that file as its official opt-out method, so current compliance is not documented well enough to rely on the rule alone. Use the live Censys network list at the firewall when collection must stop. Blocking prevents later observations; it does not delete historical records. Censys says host and virtual-host services usually disappear from search 24 to 48 hours after the last observation.

Examples

  • A server receives `CensysInspect/1.1` at `/`, redirects it to HTTPS, and then logs a follow-up request used to identify the application.
  • A network owner opts out by blocking the scanner ranges published by Censys, then waits for the last observation to age out of the current search view.
