NetManager Light
by Telesoft Ltd.

  NetManager Personal Firewall is simple, but very powerful firewall. The firewall continuously checks all your Internet traffic. If there is a suspicion that information sent to Internet or received from it may be dangerous for your computer or your confidentiality that transmission will blocked and you will get a notification about potentially dangerous traffic. You can decide whether to transmit this information or not. NetManager guards the "doors" to your computer-that is, the ports through which Internet traffic comes in and goes out. The firewall only lets traffic through the ports that you have specified can be used. No one can sneak into your computer through an unguarded port. Programs on your computer can't use unguarded ports to contact the outside world without your permission.
