SterJo NetStalker is a basic, lightweight firewall manager to trust or kill processes that seek access to the Internet. The program is fully configurable with regard to inbound TCP connections, and with pop-up dialogs for outbound connections.
Functional in 64-bit Windows.
This simple application works as a firewall software. It will protect your PC from any unwanted internet activity. It will watch on TCP and UDP connections which are currently enabled by services and applications you have running on your PC. Being a network traffic monitor it means that it will monitor your network traffic (for free). You will be able to block any unwanted process which is the result of internet access.
After launching the application, it will automatically scan all services and processes currently running on your PC. They will be listed under the Activity tab and you will also be able too see info related to local and remote IP addresses, and port, as well as the current status of the service. A status bar will inform you about all these connection's activity. If this internet traffic monitor notices any suspicious process that could be harmful for your PC security, a window will pop up so you will be able to quit the process and destroy it, or to allow the process to access the internet. This network monitoring software is smart enough to block those processes that don't hold with your network rules you've defined.
You can choose between Accept and reject action. To define the rules, go to the Policy tab. To add new rules, use the "Add a New Rule" option. You will get some pre-configured policies in order to help you get started. They can also be modified later. The Security menu is offering you to change modes of the application, so you can allow, filter or block the traffic. You may also pause the traffic. SterJo NetStalker is that simple.
One of the possibilities this free network monitoring software offers you is to track all the internet activity and be saved in files. There is the Log tab that saves all the logs and the History tab that saves all the actions you make.

This appears to be an almost unique app, and does what it says on the tin. I would give it only 4 stars currently, as it lacks the ability to configure how it handles outbound connections. (However, I have contacted the author, who has said he will look at this issue, with a view to an update if time permits).
In addition to its intended purpose, it also uses a relatively simple text-based configuration file. This makes it possible to semi-automate the task of blocking abusive IP addresses from accessing servers, using eg a PHP script to analyse logs, and output a list of IP addresses in the necessary format.
It also appears to co-exist OK with other firewalls that may be installed.
