Censys CLI

cencli brings the authority of internet intelligence to your terminal. Analyze assets, perform queries, and hunt threats, all from the command line.

cencli

The Censys CLI is available for free and paid users of the Censys Platform, with support for macOS, Linux, and Windows.

Quick Start

Make sure you have cencli installed and it is on your $PATH.

Run this command and follow the prompts to add your Censys Platform personal access token:
```
$ censys config auth add
```
(Optional) Run this command and follow the prompts to add your Censys Platform organization ID:
```
$ censys config org-id add
```
That's it! You can now perform asset lookups, searches, and more with the censys command.
```
$ censys view 8.8.8.8
```

Installation

This section describes how to get cencli on your system.

Homebrew

macOS and Linux users can install cencli using Homebrew:

$ brew install censys/tap/cencli

At the end of the installation process, zsh and bash completion scripts will be automatically generated and linked to your shell environment.

[!WARNING] Do NOT try to run brew install censys. This is a legacy formula that is no longer maintained and in no way affiliated with cencli.

For Windows users (and those who prefer not to use Homebrew), you will need to use different methods, which are described below.

Downloading the Binary

Stable binaries for different platforms (macOS/Linux/Windows) and architectures (amd64/arm64) are available for download on the releases page. After you've downloaded and extracted the binary, make sure you add it to your $PATH.

[!WARNING] For macOS users, your system may complain about the executable being untrusted after you try to run it. To bypass this, you can run xattr -dr com.apple.quarantine /path/to/binary to remove the quarantine flag. If you prefer to do this through the GUI, go to Settings > Privacy & Security and allow the executable to be run.

Go Install

If you have Go 1.25+ installed, you can install cencli using the following command:

$ go install github.com/censys/cencli/cmd/cencli@latest
# make sure to rename the executable to 'censys'
$ mv "$(go env GOPATH)/bin/cencli" "$(go env GOPATH)/bin/censys"

Build from source

Ensure you have Go 1.25+ installed, and run the following commands:

$ git clone https://github.com/censys/cencli.git
$ cd cencli
$ make censys # builds the executable to ./bin/censys
$ export PATH=$PATH:$(pwd)/bin
$ censys --help
