Configure Sensor Proxy to Use a Third-Party HTTP Proxy

Sensor Proxy supports integration with third-party HTTP proxy servers, allowing all outbound sensor traffic to be routed through a custom-designated proxy. This enhancement enables your organization to comply with internal security policies that require all outbound network communications to pass through a centralized proxy.

With this feature, you can:

Configure Sensor Proxy to send all outbound traffic through your organization’s approved third-party HTTP proxy.
Simplify network and firewall management by centralizing sensor communications.
Maintain compliance with enterprise security requirements and regulatory standards.

Note: Sensor Proxy only supports basic authentication for third-party proxy connections.

To enable Sensor Proxy to use a third-party HTTP proxy:

Do one of the following:
- Create the proxy.env file as a symlink by running the following command:
  Copy
```
ln -s </path/to/your/envfile> /opt/sensor_proxy/config/proxy.env
```
- Create the /opt/sensor_proxy/config/proxy.env file, directly add your proxy environment variables following your organization's procedures, and save the file.
  
  The following lines are examples of custom proxy environment variables in proxy.env:
  
  https_proxy="http://username:[email protected]:3128"
  
  no_proxy="localhost,127.0.0.1"
  
  Note: You must URL-encode any special characters in the username or password for proxy environment variables, as Sensor Proxy reads these values as URLs.
Restart Sensor Proxy and apply your changes by running the following command:
Copy
```
systemctl restart sensorproxy
```

To disable third-party HTTP proxy support in Sensor Proxy:

Do one of the following:
- Remove the symlink from proxy.env by running the following command:
  Copy
```
rm /opt/sensor_proxy/config/proxy.env
```
- Open proxy.env, comment out or remove your proxy environment variables following your organization's procedures, and save the file.
Restart Sensor Proxy and apply your changes by running the following command:
Copy
```
systemctl restart sensorproxy
```
