Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).
Diladele Web Safety is an ICAP server that integrates with an existing Squid proxy server and provides rich content and Web filtering functionality to sanitize Internet traffic passing into an internal home/enterprise network. It blocks pornography and explicit (adult) content by deep inspecting HTML content and URLs, blocks file downloads, performs filtering based on groups, controls Web usage by categories, removes annoying Web ads, and protects online privacy by disallowing access to Web trackers. It runs on any FreeBSD derived platform, RedHat, CentOS, Debian, and Ubuntu Linux, Raspberry PI, and Apple OS X, providing a comprehensive Web filtering solution easily manageable via a Web UI.
Hiawatha is a secure and advanced Web server for Unix. It has been written with security as its main goal.

Firekeeper is an intrusion detection and prevention system for Firefox. It is able to detect, block and warn the user about malicious sites. Firekeeper uses flexible rules similar to Snort ones to describe browser-based attack attempts. Rules can also be used to effectively filter different kinds of unwanted content.
Shishi is a (still incomplete) implementation of Kerberos 5, which can be used to authenticate users in distributed systems. It contains a library that can be used by application developers, and a command line utility for users. Shishi supports Kerberos authenticated telnet client/server, IMAP client/server (via GSSAPI), SSH client/server (via GSSAPI), rsh/rlogin client, and a PAM module for host security.
MatrixSSL is an embedded SSL and TLS implementation designed for small footprint devices and applications requiring low overhead per connection. The library is less than 50K on disk with cipher suites. It includes SSL and TLS client and server support, session resumption, and implementations of RSA, AES, 3DES, ARC4, SHA1, and MD5. The source is well documented and contains portability layers for additional operating systems, cipher suites, and cryptography providers.
