When running scans, you can use the information in the user-agent header to identify HTTP requests from Probely.
Here is an example of a user-agent header:
Mozilla/5.0 (compatible; +https://probely.com/sos) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/184.108.40.206 Safari/537.36 ProbelySPDR/0.2.0
If you notice, there is a specific string in the header:
Use it to identify Probely requests and do not rely on any other information you find in the header for that effect.
Another alternative to identify Probely requests is through their IP address.
