Your sensor communicates with multiple systems to download configuration and upload test results. Below is a list of the minimum URLs which you will need to whitelist in order for the sensor to function correctly. Any additional services which you set up for testing might also need to be whitelisted in order for them to be tested correctly.
This is the primary URL for all sensor communication with our backend systems
These are additional URLs that the sensor uses to upload results and download over the air firmware updates, tools, and patches:
The following URLs are used by the sensor to test whether it has external connectivity. If it can't access them then the sensor will report a "No connectivity" issue on the dashboard. No sensitive data is transferred to or from these locations.
Warning: if your network has a Captive Portal, depending on your setup, you probably do NOT want to whitelist the following URLs. This is because the sensor might not be properly redirected to the Captive Portal. Instead, the following URLs should be accessible, but result in a Captive Portal redirect response for unauthenticated clients.
