Though not everyone agrees that a firewall beyond the ones included in OS X is needed, Little Snitch is the most-recommended third-party firewall for Mac users. Little Snitch adds outbound threat protection -- a shortfall of the primary Mac firewall -- and includes a network monitor that tracks exactly which applications are accessing your local network and the Internet. If you want to use the Mac's secondary firewall for more protection -- including protection from outbound threats -- experts recommend a third-party firewall manager like NoobProof (for beginners) and WaterRoof (for advanced users). Both are free.

It's been a while since professional reviewers have weighed in on Little Snitch, but an older review at ZDNet.com remains somewhat useful. For a snapshot of how the program currently fares, we look at user reviews at sites like Download.com and MacUpdate.com

Jason D. O'Grady recommends Little Snitch as a good way to keep track of which programs on your Mac are communicating with the rest of the world. He does say that the initial process of setting up which programs can and can't access the net can be "exhaustive," but O'Grady provides some tips to make things go smoother. Once you get past the initial deny/accept pop-ups (he hints to use the "forever" button) and customize the product to suit your needs O'Grady says you'll be satisfied with the performance of Little Snitch.
