We tend to take for granted that apps know and track a lot about us—probably more than you realize. Some apps constantly phone home, relaying back all sorts of information. Bloop’s latest app Web Security ($10) doesn’t stop them from doing so, but at least gives you a better sense of all the connections that are coming and going from your Mac.
Web Security monitors every outgoing autonomous internet connection, and presents the info to you in a very accessible way. Broken down into either day or month views, you can see every single source, followed by the ratings for Trustworthiness, Vendor Reliability, Privacy, and Child Safety. It even shows you a map of the actual physical location where the connection is going—Seattle seems to be a big one.
