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.
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.

Excellent utility which monitors outgoing traffic & notifies of how many IPs some programs connect to (such as Skype). If being infected, one of the first things malware does is 'call home' which will allow you to block it. Probably, one of the best security software tools, you wont regret buying it.
This is the best thing I've found for alerting me to apps that are trying to make outgoing Internet connections. The amount of control I have over when those connections are allowed, and who can make them, is invaluable to me. Simply put, this is one of 2 pieces of software that I've owned for many years, that I've never regretted spending the money on. ChronoSync is the other one.
The capabilities this application has are truly unique. I mean, there are plenty of programs that track your ingoing connections (some anti-viruses even going so far as blocking the whole web-connection on your computer: I has problems like that with a couple of security software programs). But this thing makes something completely different: it tracks you outgoing connections, therefore. combined with Firewall, it provides your machine with complete connection security.
