Tor is free software and an open network that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security. 
This guide guides your through installing tor in Kali Linux.
Why anonymity matters?
Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location.

Installing Tor in Kali Linux:
Step 1: Getting tor service ready
There are 3 ways of installing Tor service in Kali Linux. You can install Tor by following any of these options:
Option #1: Install Tor from Kali Repository
Tor is available in Kali repository, to install it directly from the repository open your Terminal and type this:
apt-get install tor
If no error occurs, follow the second step.
Option #2: Install Tor from Debian Wheezy Repository
If you can’t install Tor using the first method then you may try this option. In this way we are going to add the official Tor repository according to our Debian distribution. Not to be confused, Kali is actually based on Debian and it uses the package management from “Wheezy”. So we are going to use “Wheezy” as our distribution.
Now open your terminal and follow these steps:
Step #1: Add repo to sources.list file
Lets add the distribution in the list by opening the sources.list file
leafpad /etc/apt/sources.list
Now add the following line at the bottom of the file,
deb http://deb.torproject.org/torproject.org wheezy main
Step #2: Add GPG Keys
Now we need to add the gpg key used to sign the packages by running the following commands:
gpg --keyserver keys.gnupg.net --recv 886DDD89 gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add -
Step #3: Update package lists
Lets refresh our sources:
apt-get update
Step #4: Install singing keys
Now, before installing the Tor we must add the signing key,
apt-get install deb.torproject.org-keyring
Step #5: Install Tor from Debian repository
Finally,
apt-get install tor
Now Tor should be installed!
If no error occurs, follow the second step.
Option #3: Install Tor from development branch
If you are an advanced user and you want to install Tor using the development branch then this method is for you.
Step #1: Add Tor project repository to sources.list
You need to add a different set of lines to your /etc/apt/sources.list file:
deb http://deb.torproject.org/torproject.org wheezy main deb http://deb.torproject.org/torproject.org tor-experimental-0.2.5.x- wheezy main
Step #2: Add GPG keys, keyring and install Tor
Then run the following commands at your command prompt:
gpg --keyserver keys.gnupg.net --recv 886DDD89 gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add - apt-get update apt-get install tor deb.torproject.org-keyring
Now Tor should be installed!
If no error occurs, follow the second step.
Note: This release will provide you more features but it contains bugs too.
Option #4: Build and Install Tor from sources
If you want to build your own debs from source you must first add an appropriate deb-src line to sources.list.
deb-src http://deb.torproject.org/torproject.org wheezy main deb-src http://deb.torproject.org/torproject.org wheezy main deb-src http://deb.torproject.org/torproject.org tor-experimental-0.2.5.x--wheezy main
You also need to install the necessary packages to build your own debs and the packages needed to build Tor:
apt-get install build-essential fakeroot devscripts apt-get build-dep tor
Then you can build Tor in ~/debian-packages:
mkdir ~/debian-packages; cd ~/debian-packages apt-get source tor cd tor-* debuild -rfakeroot -uc -us cd ..
Now you can install the new package:
dpkg -i tor_*.deb
Step #2: Downloading and Running Tor bundle
Download the Tor Bundle from here,
https://www.torproject.org/projects/torbrowser.html.en
Download the architecture-appropriate file above, save it somewhere, then run one of the following two commands to extract the package archive:
tar -xvzf tor-browser-gnu-linux-i686-2.3.25-15-dev-LANG.tar.gz
or (for the 64-bit version):
tar -xvzf tor-browser-gnu-linux-x86_64-2.3.25-16-dev-LANG.tar.gz
(where LANG is the language listed in the filename).
Once that’s done, switch to the Tor browser directory by running:
cd tor-browser_LANG
(whereLANG is the language listed in the filename).
To run the Tor Browser Bundle, execute the start-tor-browser script:
./start-tor-browser
This will launch Vidalia and once that connects to Tor, it will launch Firefox.
Note: Do not unpack or run TBB as root. (though in Kali Linux, it doesn’t make any differences)
Conclusion
How secured is TOR? It’s only as secured as the upstream nodes are! VPN is always better solution and to be honest, VPN is faster than TOR. In case you’ve already tried TOR and it didn’t hold up to your requirements, you should try to setup VPN to bypass security or restrictions. torsocks is another alternative to using TOR and it’s somewhat faster as there’s less users on that at anytime.
