Whonix ™ is an anonymous operating system that runs like an app and routes all Internet traffic through the Tor anonymity network. It offers privacy protection and anonymity online and is available for all major operating systems.
Whonix ™ uses an extensively security reconfigured Debian base (Kicksecure ™ Hardened) which is run inside multiple virtual machines (VMs) on top of the host OS. This architecture provides a substantial layer of protection from malware and IP leaks. Applications are pre-installed and configured with safe defaults to make them ready for use with minimal user input. Learn more.
Privacy First Users
The increasing threat of mass surveillance and repression all over the world means our freedoms and privacy are rapidly being eroded. Whonix ™ is a powerful solution to this problem. Anyone who values privacy, has business secrets, needs private communication or does sensitive work on their desktop or online can greatly benefit from using Whonix ™. Learn more.
Whonix ™ consists of two VMs: the Whonix-Gateway ™ and the Whonix-Workstation ™.
The former runs Tor processes and acts as a gateway, while the latter runs user applications on a completely isolated network. This innovative architecture allows for maximum privacy, keeps applications in check and makes DNS leaks impossible. Learn more.
Now we're diving deep into what makes Whonix ™ great. We'll provide a more detailled look and lots of links for you to even more thoroughly study Whonix ™.
Whonix ™ is a free and open-source desktop operating system (OS) that is specifically designed for advanced security and privacy. It's based on the Tor anonymity network, security-focused Linux Distribution Kicksecure ™
, GNU/Linux and the principle of security by isolation.
Whonix ™ defeats common attacks while maintaining usability. Online anonymity and censorship circumvention is attainable via fail-safe, automatic and desktop-wide use of the Tor network. This helps to protect from traffic analysis by bouncing communications around a distributed network of relays run by global volunteers. Without advanced, end-to-end, netflow correlation attacks, an adversary watching an Internet connection cannot easily determine the sites visited, and those sites cannot discover the user's physical location. 
Whonix ™ uses an extensively security reconfigured Debian base (Kicksecure ™ Hardened). It consists of two virtual machines -- Whonix-Gateway ™ and Whonix-Workstation ™ -- which are designed to be used on a supported host OS (Host Operating System Selection). The host OS supporting Whonix ™ is usually the one installed on the user's computer, but OSes installed on external drives will also work (USB Installation). Users choose the preferred Whonix ™ configuration and may use either a Type I hypervisor (Qubes-Whonix ™), or a Type II hypervisor like KVM and Virtualbox.
This architecture provides a substantial layer of protection from malware and IP leaks. Applications are pre-installed and configured with safe defaults to make them ready for use with minimal user input. The user may install custom applications or personalize their desktop without fear of information leaks that could lead to de-anonymization. Whonix ™ is the only actively developed OS designed to be run inside a VM and paired with Tor. Though technically a "desktop" operating system, the security and anonymity tools Whonix ™ provides also make it ideally suited for hosting secure and anonymous onion services.
By helping users run applications anonymously Whonix ™ aims to preserve privacy and anonymity. A web browser, IRC client, office suite, and more come pre-configured with security in mind. Internet traffic by Whonix ™ is all routed through the Tor anonymity network.
Whonix ™ is Freedom Software and is based on Kicksecure ™
(security-focused Linux Distribution), Tor , Debian GNU/Linux , and the principle of security by isolation.
Whonix ™ User Groups
Privacy is a human right. The increasing threat of mass surveillance and repression all over the world means our freedoms and privacy are rapidly being eroded. Whonix ™ is a powerful solution to this problem. Anyone who values privacy, has business secrets, needs private communication or does sensitive work on their desktop or online can greatly benefit from using Whonix ™. This includes the following. Also see Users of Whonix ™.
- Investigators and whistleblowers whose work threatens the powerful. Within our isolated environment, research and evidence can be gathered without accidental exposure.
- Researchers, government officials or business-people who may be targets of espionage. Anti-malware and anti-exploit modifications lower the threat of trojans and backdoors.
- Journalists who endanger themselves and their families by reporting on organized crime. Compartmentalized, anonymous Internet use prevents identity correlation between social media and other logins.
- Political activists under targeted surveillance and attack. The usefulness of threatening the ISP in order to analyze a target's Internet use is severely limited. The cost of targeting a Whonix ™ user is greatly increased.
- Average computer users in a repressive or censored environment. Easy Tor setup and options for advanced configurations means users in repressive countries can fully access the Internet desktop-wide, not just in their browser.
- Average computer users who simply don’t want all or some aspect of their private lives uploaded, saved and analyzed. Whonix ™ does not silently upload identifying information in the background.
Whonix ™ Architecture
Whonix ™ consists of two VMs: the Whonix-Gateway ™ and the Whonix-Workstation ™.  The former runs Tor processes and acts as a gateway, while the latter runs user applications on a completely isolated network. The Whonix ™ architecture affords several benefits:
- Only connections through Tor are permitted.
- Servers can be run, and applications used, anonymously over the Internet.
- DNS leaks are impossible.
- Malware with root privileges cannot discover the user's real IP address.
- Threats posed by misbehaving applications and user error are minimized.
- The platform has extensive security hardening.
Full Spectrum Anti-Tracking Protection
Hiding your identity is harder than just hiding your IP. Internet tracking companies don't even need to know your IP address to be able to identify you. They have multiple alternative tracking technologies in their arsenal. Whonix provides full spectrum anti-tracking protection.

Based on Debian
Tip: Since Ubuntu is a Debian derivative, online help for Ubuntu most often works for Whonix ™.
In oversimplified terms, Whonix ™ is just a collection of configuration files and scripts. Whonix ™ is not a stripped down version of Debian; anything possible in "vanilla" Debian GNU/Linux can be replicated in Whonix ™. Likewise, most problems and questions can be solved in the same way. For example: "How do I install VLC Media Player on Whonix ™?" -- "The same way as in Debian
apt install vlc. Whonix ™ does not break anything, limit functionality, or prevent installation of compatible software.
Security by Isolation
Whonix ™ is the best way to use Tor and provides the strongest protection for your privacy online by hiding your real IP address, because Whonix ™ protects from leaks. In laymen's terms a leak occurs if a user expects to be wholly using Tor, but instead some application traffic bypasses Tor and is routed over the normal internet (clearnet). A solitary leak is all that is required to de-anonymize the user, for example via IP leaks, DNS leaks, UDP and other channels.
Even when Tor provides sufficient anonymity, it can be very complicated or impossible for users to configure applications so all traffic is routed through the Tor network. The reason is networking is very complex and most applications are not designed with anonymity or privacy in mind. Some applications like the Tor Browser Bundle are specifically designed for anonymity and attempt to eliminate all known leak vectors. Unfortunately, despite all best efforts leaks have occurred in the past due to Tor Browser Bundle software defects (bugs). In such cases, Whonix ™ users were protected and unaffected by these leaks.
In Whonix ™, DNS and other related leaks (IP, DNS, UDP, ICMP) are impossible. Even malware with root privileges cannot discover the user's real IP address because Whonix ™'s split-VM design ensures all internet traffic is routed through Tor.
Whonix ™ is divided into two VMs:
- Whonix-Gateway ™ to enforce routing of all Internet traffic through the Tor network, and
- Whonix-Workstation ™ for work activities. Whonix-Workstation ™ is unaware of its real external IP address, which means the user's real external IP address is always protected and leaks are impossible.
This security by isolation configuration averts many threats posed by malware, misbehaving applications, and user error.

This is not an empty claim -- Whonix ™ has been audited via the corridor (Tor traffic whitelisting gateway) and other leak tests. In over a decade, no leaks were ever discovered. Technical readers can refer to the Whonix ™ technical introduction and security overview chapters for further details.
Online Anonymity via Tor
Whonix ™ relies on the Tor network to protect a user's anonymity online; all connections are forced through Tor or otherwise blocked. Tor helps to protect users by bouncing communications around a distributed network of relays run by volunteers all around the world. Without advanced, end-to-end, netflow correlation attacks, anybody watching a user's Internet connection cannot easily determine the sites visited, and those sites cannot learn the user's physical location.

Quote Qubes-Whonix ™ version support policy:
Whonix ™ templates are supported by our partner, the Whonix ™ Project. The Whonix ™ Project has set its own support policy for Whonix ™ templates in Qubes.
This policy requires Whonix ™ template users to stay reasonably close to the cutting edge by upgrading to new stable releases of Qubes OS and Whonix ™ templates within a month of their respective releases. To be precise:
- One month after a new stable version of Qubes OS is released, Whonix ™ templates will no longer be supported on any older release of Qubes OS. This means that users who wish to continue using Whonix ™ templates on Qubes must always upgrade to the latest stable Qubes OS release within one month of its release.
- One month after new stable versions of Whonix ™ templates are released, older releases of Whonix ™ templates will no longer be supported. This means that users who wish to continue using Whonix ™ templates on Qubes must always upgrade to the latest stable Whonix ™ template releases within one month of their release.
We aim to announce both types of events one month in advance in order to remind users to upgrade.
