Editors' Review

With Little Snitch, you can monitor your Mac's network activity, control which apps and services can use your network, and keep an eye on what's eating up your bandwidth.

Pros

Alert mode or silent mode: Little Snitch offers two ways to monitor networking traffic. Alert mode alerts you when an app tries to make a network connection to a server and lets you choose to allow or disallow it. In silent mode, Little Snitch suppresses alerts, allowing connections it determines are safe, letting you review connection attempts later.

Either way, you can watch for suspicious network activity, build a list of which apps and services can make connections and create rules for how to handle future connections.

Set limits: Little Snitch allows common activities, but it gives you control over which apps can access your network, and you set time limits and other parameters on a connection.

Monitor your traffic: Little Snitch's Network Monitor offers a live dashboard that lets you keep track of your Mac's network activity. You can see which apps and processes are active on the network. Click the reveal triangle next to an app to get much more information on what the app is up to. Its Research Assistant feature can check one of your apps against Little Snitch's app database to offer more details, including whether the app is from a known source and hasn't been modified.

Mapping your connections: A map displays in real time recent networking activity between your Mac and servers around the world. View your apps and which servers they're connecting to, a map of connections, and a detailed history of networking activity over an hour.

Cons

Setup can take some time: Little Snitch offers a wealth of options to monitor and control networking activity. However, finding the right balance for notifications and permissions may require some tweaking.

Bottom Line

Little Snitch can serve as a traffic monitor, firewall, and companion to your antivirus app. A demo version runs for 30 days and then you can purchase an individual license for $45. The app is an invaluable addition, if you want to keep tabs on your Mac's networking activities. It may, however, take a bit of tweaking to get the settings to your liking.
