Little Snitch

Rules-window-zoomed

Little Snitch informs you whenever a program attempts to establish an outgoing Internet connection. You can then choose to allow or deny this connection, or define a rule how to handle similar, future connection attempts. This reliably prevents private data from being sent out without your knowledge. Little Snitch runs inconspicuously in the background and it can also detect network related activity of viruses, trojans and other malware.

  1. Have been using this for months. Works as advertised.

  2. Definitely works you have to make sure it does block ports that you may be using for some specialty apps…R

  3. This is lovely and it reminds me of the tree at the end of the book The Giving Tree

  4. i have been using it for well over a year now. It works great however it can be a bit annoying if you forget to set it to handle future attempts in the same fashion.
