Vallum is a little tool that helps you monitor and block application connections. It is able to intercept connections at the application layer, and hold them while you decide whether to pass or block them. Vallum's interface is very simple and is icon-based. Its default configuration is not intrusive, and it does not require any interaction or specific networking knowledge or skills. Just drag an app's icon from the Finder into the main Vallum window to block it. To change Vallum's attitude and interaction level, you just have to play with the very few options available.
