Bright Data indexes public web data from large websites – typically e-commerce, travel, consumer brands, etc.
These websites are indexed to keep Bright Data’s large datasets up to date. You can see the type of data collected and the websites the information is collected from in the datasets page.
Since it is Bright Data who creates the original requests to specific websites, so we know what URLs are visited at all times.
Irrespective to the above and as an additional layer of security, Bright Data uses leading 3rd party web-filtering software to ensure only allowed sites may be indexed.
