Vuurmuur is designed to be both simple and powerful. In addition to standard firewall capabilities, it also supports traffic shaping and offers advanced monitoring capabilities. Operating System: Linux.

53. m0n0wall

Replaces Barricuda NG Firewall

Although it was designed for embedded PCs and appliance, m0n0wall can also run on a standalone PC running FreeBSD. It requires less than 12MB of space and boots in less than 25 seconds. Operating System: FreeBSD.

54. pfSense

Replaces Barricuda NG Firewall, Check Point Appliances

This m0n0wall fork is also based on BSD, but is designed for regular computers, not embedded hardware. It's been downloaded more than 1 million times and currently runs on more than 100,000 networks, including large corporations and universities as well as small home networks.

The "core" Vyatta software allows users to make their own firewalls/networking appliances and routers. The company also offers paid software and hardware. Operating System: Linux.

Calling itself the "world's foremost network protocol analyzer," Wireshark makes it easy to capture and analyze network traffic. Commercial products and services related to the software are available through Riverbed Technology. Operating System: Windows, Linux, OS X.

57. tcpdump/libpcap

Replaces: OmniPeek, CommView,

Tcpdump is a command line packet analyzer, and libpcap is a C/C++ library for network traffic capture. Working together, the two provide a good network monitoring solution, but, lacking a GUI, they are not particularly user-friendly. Operating System: Linux.

58. WinDump

60. Access Data Password Recovery Toolkit, Passware

John the Ripper is particularly good at cracking weak passwords, but in order to use it, you'll need a list of commonly used passwords. You can buy password lists or a pro version of the software from the same site. Operating System: Windows, Linux, OS X.

Password Management

Replaces Kaspersky Password Manager

Downloaded more than 1 million times, Password Safe is another popular open source option for protecting your passwords. Like KeePass, it's lightweight and stores your encrypted passwords in a database so that you only need to recall one master password. Operating System: Windows.

User Authentication
