"Brave Browser Takes Action Against Website Port Scanning and Enhances Privacy"
Originally Published 2 years ago — by Ars Technica

Brave browser will automatically block websites from scanning visitors' open Internet ports or accessing other network resources that can expose personal information. This new feature aims to curb the practice of port scanning and fingerprinting visitors without their consent. Users can add specific sites to an allow list if they want them to have access to local resources. Brave is the only browser that blocks requests to localhost resources from both secure and insecure public sites while maintaining compatibility for trusted sites.
