Little Snitch is a firewall utility designed for Mac. This program might prove to be of good use if you wish to protect your computer against unwanted guests from the Web. The application identifies unwanted connection attempts and lets you decide how to proceed next.

Once you're connected to the Internet, some of your Mac applications might send some important information, such as your current location, credentials, etc. Little Snitch helps you prevent this event from happening as it lets you know the exact moment an app attempts to send your private data and provides you with a solution for stopping it from occurring again.

For example, you can configure Little Snitch to authorize incoming connections for the Mac App Store program and forbid outgoing connections for the Safari browser. These so-called rules can easily be changed by going to the Preferences menu of the application.

Another helpful feature is the Network Monitor utility. This tool helps you monitor the network traffic, analyze the bandwidth and connectivity status, etc.

Also, this new version of Little Snitch provides you with support for macOS 10.12 Sierra.

In conclusion, you should give this program a try if you wish to protect your privacy on your Mac. It works flawlessly, uses minimum CPU resources, and is affordable.
