Tor is a toolset for a wide range of organizations and people that want to improve their safety and security on the Internet. Using Tor can help you anonymize web browsing and publishing, instant messaging, IRC, SSH, and more. Tor also provides a platform on which software developers can build new applications with built-in anonymity, safety, and privacy features. Killer App hot

It includes HTTP proxy with HTTPS and FTP support, SOCKSv4/SOCKSv4.5/SOCKSv5 proxy (socks/socks.exe), POP3 proxy, SMTP proxy, AIM/ICQ proxy (icqpr/icqpr.exe), MSN messenger / Live messenger proxy (msnpr/msnpr.exe), FTP proxy, caching DNS proxy, TCP and UDP portmappers.
BDFProxy is the Backdoor Factory Proxy.
BinProxy is a proxy for arbitrary TCP connections. You can define custom message formats using the BinData gem.
DNS reverse proxy
DNS reverse proxy is a DNS reverse proxy to route queries to different DNS servers.
DNSChef is a highly configurable DNS proxy for Penetration Testers and Malware Analysts. A DNS proxy (aka "Fake DNS") is a tool used for application network traffic analysis among other uses.
dnsrecon is a DNS enumeration script.
elite-proxy-finder finds elite anonymity (L1) HTTP proxies then tests them all in parallel.
FakeDns is a regular-expression based python MITM DNS server with support for DNS Rebinding attacks.
mitmdump is the command-line companion to mitmproxy. It provides tcpdump-like functionality to let you view, record, and programmatically transform HTTP traffic.
Obfsproxy is a pluggable transport proxy written in Python.
pr0cks is a Python script to transparently forward all TCP and DNS traffic through a socks (like ssh -D option) or HTTPS (CONNECT) proxy using iptables -j REDIRECT target.
proxychains is a hook preloader that allows to redirect TCP traffic of existing dynamically linked programs through one or more SOCKS or HTTP proxies.
Proxyp is a small multithreaded Perl script written to enumerate latency, port numbers, server names, & geolocations of proxy IP addresses.
redsocks is a tool that allows you to redirect any TCP connection to SOCKS or HTTPS proxy using your firewall, so redirection is system-wide.
SoapUI is the de-facto standard for REST and SOAP API functional, security and performance testing.
sshuttle is a transparent proxy server that works as a poor man's VPN. Forwards over ssh.
SSRF Proxy facilitates tunneling HTTP communications through servers vulnerable to Server-Side Request Forgery.
starttls-mitm is a mitm proxy that will transparently proxy and dump both plaintext and TLS traffic. It uses a user-provided keyfile and certificate file to impersonate remote servers.
striptls is a generic tcp proxy implementation and audit tool to perform protocol independent ssl/tls interception and STARTTLS stripping attacks on SMTP, POP3, IMAP, FTP, NNTP, XMPP, ACAP and IRC.
tftp-proxy accepts connection on tftp and reloads requested content from an upstream tftp server. meanwhile modifications to the content can be done by pluggable modules.
Tinyproxy is a small, efficient HTTP proxy, which is ideal for use in small network situations where a (much) larger, caching proxy like Squid might very well be overkill. Read more
Torsocks allows you to use most applications in a safe way with Tor. It ensures that DNS requests are handled safely and explicitly rejects any traffic other than TCP from the application you're using.
WebFig is a web management interface that comes with MikroTik's RouterOS. By default it encrypts HTTP traffic (even without SSL/TLS) by implementing an authentication and encryption scheme similar to PPTP (MS-CHAP-V2 for authentication, MPPE key derivation and RC4 for encryption).
