undocumented connections to known trackers/analytics), improve user security (data on baseline app behaviour can potentially be used to detect anomalous behaviour due to malware) and to improve our understanding of the app ecosystem. By collecting data on the connections made by applications the study aims to highlight potential privacy issues (e.g. The app is part of a research project in the School of Computer Science and Statistics at Trinity College Dublin, Ireland. Can encrypt your DNS traffic using DNS-over-HTTPS. Also allows blocking of all network connections for specified apps, blocking of all connections except for specified whitelisted connections, use of pre-configured lists of connections per app to allow/block etc. Supports use of hostname lists ( Energized Blu etc) to block known tracker and advertising domains for all apps.

Allows real-time monitoring of network connections being made by applications, and blocking/allowing of these per app by user. A free, fully open-source application firewall for macOS 10.13 High Sierra and later.
