Little Snitch protects your privacy! As soon as you’re connected to the Internet, applications can potentially send whatever information they want to wherever they want. Sometimes they do this for good reason, on your explicit request. But often they don’t. Little Snitch intercepts these unwanted connection attempts, and lets you decide how to proceed.
Track background activity
As soon as your computer connects to the Internet, applications often have permission to send any information wherever they need to. Little Snitch takes note of this activity and allows you to decide for yourself what happens with this data.
Control your network
Choose to allow or deny connections, or define a rule how to handle similar, future connection attempts. Little Snitch runs inconspicuously in the background and it can even detect network-related activity of viruses, trojans, and other malware.
Network Monitoring Redefined.
Take a look under the hood to see at a glance who talks to whom. The Little Snitch Network Monitor raises the bar of network traffic monitoring to an entirely new level. The realtime diagram provides fine grained traffic information, combined with powerful yet simple options for analyzing bandwidth, traffic totals, connectivity status and much more.
Silent Mode – Decide Later
There are times where you don’t want to get interrupted by any network related notifications. With Silent Mode you can quickly choose to silence all connection warnings for a while. You can then later review the Silent Mode Log to define permanent rules for connection attempts that occurred during that time.
Automatic Profile Switching
Rules can be arranged in different profiles like “Home”, “Office” or “Mobile Internet”. This allows you to use different sets of filter rules depending on the network you are currently connected to. Profiles can be activated either manually from the status menu, or automatically, whenever you join a network that’s associated with one of your profiles.
Firewall for incoming connections
Little Snitch not only reveals any outgoing network connection attempt to make sure that sensitive data doesn’t leave your computer without your consent. The inbound firewall in Little Snitch provides you with the same level of control for incoming connections.
