14 Best Linux Distributions for Privacy and Security in 2023

Being anonymous on the Internet is not particularly the same as surging the web safely, however, they both involve keeping oneself and one’s data private and away from the prying eyes of entities that may otherwise take advantage of system vulnerabilities in order to harm targeted parties.

There is also the risk of surveillance from the NSA and several other top-level organizations and this is why it is good that developers have taken it upon themselves to build privacy-dedicated distros that host an aggregate of tools that enable users to achieve both online autonomy and privacy.

In as much as these privacy-centric Linux distros are targetted at a niche in the Linux community, many of them are robust enough to be used for general-purpose computing and many more can be tweaked to support requirements for virtually any specific user base.

A common factor across almost all privacy-centric Linux distros is their relationship with Tor given that many of them come with Tor’s solid anonymity network service built-in.

Tor’s anonymity gives users an environment for them to live safely without any data logs whatsoever, unlike most VPN providers that will still log your real IP address while still being able to see whatever data you may be transmitting at the point of exit of VPN servers.

However, VPN still has a sheer amount of advantages over the former which makes it somewhat superior in a way (depending on your use case) – particularly, when you put P2P file-sharing, and general Internet speed into consideration, VPN wins here (more on that later).

The Tor network secures all network traffic that goes through it by bouncing the data off several random nodes in order to reduce the traffic’s traceability chances.

Mind you, during this process, every piece of data is re-encrypted several times as it passes through the randomly selected nodes before finally reaching its destination as illustrated in the images below.

Most Secure Linux Distributions

Now that you have a basic understanding of how Tor works to the advantage of its users, here is our list of the Best Security-Centric Linux Distributions of this year.

1. Qubes OS

Qubes OS is a security-oriented Fedora-based distro that ensures security by implementing security compartmentalization. This happens by running every instance of running programs in an isolated virtual environment and then deleting all of its data when the program is closed.

Qubes OS uses the RPM package manager and is capable of working with any desktop environment of choice without requiring a lot of computer resources.

Cited by Edward Snowden as the “best OS available today“, it is definitely a good choice if you want to make sure that your identity and data are yours alone whether online or offline.

2. TAILS – The Amnesiac Incognito Live System

Tails is a security-centric Debian-based distro designed to protect users’ identities online and keep them anonymous. Its name stands for The Amnesiac Incognito Live System and it is built to force all incoming and outgoing traffic through the Tor network while blocking all traceable connections.

It uses Gnome as its default desktop environment and being a live DVD/USB, can be conveniently run from a pen drive when it stores all its data in the RAM.

It ships with open-source tools that are specially meant for privacy-specific reasons such as MAC address spoofing and windows camouflage, to mention a couple.

3. BlackArch Linux

BlackArch Linux is a lightweight Arch Linux-based distribution targetted at penetration testers, security experts, and security researchers.

It offers users all the features that Arch Linux has to offer combined with a ton of cybersecurity tools numbering 2000+ that can be installed either individually or in groups.

Compared to other distros on this list, BlackArch Linux is a relatively new project yet, it has been able to stand out as a reliable OS in the community of security experts.

It ships with the user option to choose any of these desktop environments: Awesome, Blackbox, Fluxbox, or Spectrwm, and as expected, it is available as a live DVD image and can be run from the convenience of a pen drive.

4. Kali Linux

Kali Linux (formerly BackTrack) is a free advanced Debian-based penetration testing Linux distribution designed for security experts, ethical hacking, network security assessments, and digital forensics.

It is built to run smoothly on both 32 and 64-bit architectures and right out of the box it comes with a bundle of penetration testing tools that make it one of the most sort-after distros by security-conscious computer users.

There is a lot more that can be said about Kali Linux (as is the case with every other Operating System in this list) but I will leave the deeper digging for you to do.

5. JonDo/Tor-Secure-Live-DVD

JonDo Live-DVD is more or less a commercial anonymity solution that works in a similar fashion as Tor given the fact that it also routes its packets via specified “mixed servers” – JonDonym – (nodes in the case of Tor) having them re-encrypted each time.

It’s a viable alternative to TAILS especially if you are looking for something with a less restrictive UI (while still a live system) and a close-to-average user experience.

The distro is based on Debian and also includes an assortment of privacy tools and other commonly used applications.

JonDo Live-DVD is, however, a premium service (for commercial use) which explains why it is targeted at the commercial space. Like Tails, it doesn’t support any native way of saving files and it goes an extra mind to claim to offer users better computing speed.

6. Whonix

If you are looking for something a little different, Whonix takes quite a different approach from those mentioned above as it is not a live system but instead runs in a VM – Virtualbox to be specific – where it is isolated from your main OS in order to minimize the risk of DNS leakage or malware (with root privilege) infiltration.

Whonix consists of two parts – the first is “Whonix Gateway” which acts as a Tor gateway while the other is “Whonix Workstation” – an isolated network that routes all its connections through the Tor gateway.

This Debian-based distro utilizes two VMs which makes it relatively resource hungry so you’ll experience lags every now and then if your hardware isn’t on the high end.

7. Discreete Linux

Discreet Linux, formerly UPR or Ubuntu Privacy Remix, is a Debian-based Linux distro designed to provide users with protection against trojan-based surveillance by completely isolating its working environment from locations with private data.

It is distributed as a live CD that cannot be installed on a hard disk and the network is deliberately disabled when it’s running.

Discreet Linux is among the unique distros on this list and is evidently not intended for everyday computing tasks like word processing and gaming. Its source code is seldom updated given the little need for updates/fixes but it ships with the Gnome desktop environment for easy navigation.

8. Parrot Security OS

Parrot Security OS is another Debian-based distribution geared towards penetration testing, ethical hacking, and ensuring anonymity online.

It contains a robust and portable laboratory for digital forensics experts that not only includes software for reverse engineering, cryptography, and privacy but also for software development and surfing the Internet anonymously.

It is distributed as a rolling release that ships with only core applications such as Tor Browser, OnionShare, Parrot Terminal, and MATE as its default desktop environment.

9. Subgraph OS

Subgraph OS is a lightweight Debian-based distribution designed to be impervious to surveillance and interference from adversaries over any network no matter their level of sophistication.

It is created to use a hardened Linux kernel coupled with an application firewall to block certain programs from accessing the network and it forces all Internet traffic to go through the Tor network.

Designed as an adversary-resistant computing platform, Subgraph OS’s objective is to provide an easy-to-use OS with specific privacy tools without compromising usability.

10. Heads OS

Heads is a free and open-source Linux distro built with the aim of respecting users’ privacy and freedom and helping them to be secure and anonymous online.

It was developed to be the answer to some of Tails’ “questionable” decisions such as using systemd and non-free software. That is to say, all the applications in Heads are free and open-source and it doesn’t use systemd as an init system.

11. Alpine Linux

Alpine Linux is a lightweight security-oriented open-source Linux distribution designed for resource efficiency, security, and simplicity based on BusyBox and musl libc.

It has been in active development since its first release in August 2005 and has since become one of the most recommended images to use when working with Docker images.

12. PureOS

PureOS is a user-friendly Debian-based distribution built with a focus on user privacy and security by Purism – the company behind Liberem computers and smartphones.

It is designed to put its users in complete control of their computing system with full customizability, eye-catching animations, and minimal data vestiges. It ships with GNOME as its default desktop environment.

13. Linux Kodachi

Linux Kodachi is a lightweight Linux distribution designed to run from a pen drive or DVD. Right out of the bat, it filters all network traffic through a Virtual Proxy Network and the Tor network in order to obscure its user’s location and it goes the extra mile to remove any traces of its activities when it is done being used.

It is based on Xubuntu 18.04, ships with an XFCE desktop environment, and several built-in technologies to enable users to remain anonymous online as well as protect their data from getting into unwanted hands.

14. TENS

TENS (formerly Lightweight Portable Security or LPS) stands for Trusted End Node Security and it is a program that boots a barebone Linux OS from a portable storage device without mounting any data on the local disk.

TENS requires no administrator privileges to run, no contact with a local hard drive, nor installation, among several other advanced security-positive features.

Oh, and fun fact, TENS is managed and produced by the Air Force Research Laboratory’s Information Directorate, of the United States Air Force.
