Little Snitch

Version: 3.3.4 || Release Date: 2014-07-23 || License: Commercial with demo ($29.95) Developer: Objective Development Software GmbH | App Owner: equinox

Alerts you of outgoing network connections.

A firewall protects your computer against unwanted guests from the Internet. But who protects your private data from being sent out? Little Snitch does!

Little Snitch informs you whenever a program attempts to establish an outgoing Internet connection. You can then choose to allow or deny this connection, or define a rule how to handle similar, future connection attempts. This reliably prevents private data from being sent out without your knowledge. Little Snitch runs inconspicuously in the background and it can also detect network related activity of viruses, trojans and other malware.

This program rendered my computer unable to connect to the internet in one fell swoop, even after I uninstalled the program. Tech support was kind but unhelpful. Definitely not getting this program.

you can't buy the full version via paypal and the support says it works - for me not

@aeko you can deactivate it if you want

i have a problem with this. I dont let my applications check for updates. i use a seperate program to batch check all my apps versions. But in shapeshifter, if it cant get a version check off, it jsut goes into this annoying panel that says "new version (null) available, and gives me download, ignore, and remind later buttons, that dont go away. so i cant configure it with this active. any thoughts?

[edit]: hahaha.... you can turn it off if you allow once.... whoops...

Good but a little annoying with the constant alerts letting me know what port/program is sending what. I guess there's no other way. Reminds me of a PopUp blocker on Windows. Useful though it is, I don't think it's worth 25$ unless you don't pay for any other software which is what a lot of people use it for.

It may be able to be worked around, but that's no reason not to use it - most security procedures can be worked around. It adds a very useful layer of security.

@ groxx: I don't claim to necessarily being able to give you a guaranteed accurate answer to your question, but here's my take.

I think that isn't possible. This app manages outgoing traffic only. Its sole intent is to manage network traffic in regards to, either blocking completely, or restrict the outbound traffic to specific conditions. In other words, It's a subtractive process.

On the other hand, you may be able set up a rule that works for your purpose. For instance, set up two rules; the first one will have Little Snitch allow all outgoing traffic from a specific program (or any program if you like), followed by a second, restrictional rule, that denies any useage of the specific "network adapters" that you are referencing (I'm not sure I understand exactly what you mean with 'adapters').

So, for instance, 'allow all kind of connections, but deny any form of outbound communication via a specific port (or port range)' and so on... The configurations possible in Little Snitch may or may not suit your wishes.

But re-routing traffic is not - to my knowledge - so far possible with Little Snitch.

Can anyone tell me if this can re-route applications to specific network adapters? That'd be EXTREMELY useful for me...
