15 Most Secure Linux Distros for Privacy & Security Concern Users

So you are a Linux user and looking for the Most Secure Linux Distro to secure and make strong privacy for your operating system? Here are the Top 15 Most Secure Linux Distros for Privacy and Security Concern Linux Users.

Before we get started, let’s talk about why Linux Distro is too important to avoid? Okay, you may already know that the OS is the core software that allows you to communicate with the hardware and software of your computer. It manages all the hardware and makes contact with the processor and memory.

If you are using your pc without being secured enough, then it will be easy for the hackers to access your operating system, and that can allow them to exploit the operating system, to see the files and even the location from where you have been on the internet. In this situation, Linux distros provide a lot of choices to select a list of the best and most secure Linux distros for your system.

Most Secure Linux Distros

The number of Linux users is increasing immensely day by day. Their specialty is that they are less common than the other operating systems out there. And still, they are working to be more technical in the upcoming days.

Here is the Most Secure Linux Distros list, which is’Specially Focused on Linux security.’ That means this article is done especially by focusing on Sharp Security that a Linux user is more concerned about.

1. Qubes OS

If you are looking for the most secure Linux distro for your desktop here, Qubes comes up at the top. Why am I saying that? Well, Qubes is a Fedora-based operating system that focused on desktop security. This OS will secure you by isolating and virtualizing various VM separately.

Qubes isolate your personal files from the malware without being affected. It’s cool. Note that this OS is best for advanced users. So if you are new, then it will be a bit tough for you to manage this system.

Download Qubes OS

2. Tails

Tails are one of the best most Secure Linux Distros out there after Parrot Security OS. Tails first released in 2009. This Operating System developed especially targeting personal computers. If you are looking for an OS that will keep you safe while browsing the internet, then Tails will take the first place.


It’s a live CD and a pre-installed Operating System with the Tor browser bundle using the onion circuit. Since all the outgoing connection goes through the Tor, it allows you to use the internet anonymously, and whatever you do, it never leaves any trace behind.

Tails OS doesn’t use any hard disk space; instead, it only uses the required space in your RAM, but it will be erased automatically when you shut down your system. It can be used as a live DVD or live USB. It will be more convenient to boot from a USB stick rather than a DVD. However, there are some issues with this OS. Recently most of the users are claiming that Tails requires 2 USB sticks while installing, which is boring.

3. Parrot Security OS

FrozenBox developed parrot Security OS and was released in 2013. This software is a game-changer when it comes to security & privacy concerns of a Computer’s Operating System. Parrot Security OS is specially designed to test an authorized simulated attack on your computer system, which helps assess your system’s vulnerabilities, whether it is strong enough or not.

It comes with a full portable laboratory that protects your system from any unwanted disease while working on the internet, browsing anything, playing a game, etc. Again if you are a forensic expert, then this operating system is the best, and nothing can go beyond this.

Download Parrot Security OS

4. Kali Linux

Kali Linux is a pre-installed Debian-derived Linux distro, which is developed especially focusing on Pen Testing and Forensic Experts. Kali comes along with a package of tools such as-Aircrack-ng, Ettercap, Foremost, Wireshark, Kismet, Maltigo, and many others, which helps you in many ways like exploiting a victim network or application, performing network discovery, or surveying a target IP address.

Not only that, Kali includes a graphical cyber attacking tool name Armitage which allows you to lunch and exploits, get exploits recommendations, and advanced features of the Metasploit Framework’s meterpreter. Kali Linux has considered one of the top-ranked, most secure Linux distros out there for developers.

Like Tails, this OS also can be booted as a live DVD or USB stick, and it is easy to use than the other OS available out there. Whether you run 32 or 62 operating systems, Kali Linux can be used on both. This OS requires a minimum of 512MB RAM & 10GB hard disk space to be installed.

Download Kali Linux

5. Whonix

If you want to private your IP address, then Whonix is the perfect one you can have. Whonix is a Debian-based operating system that focused specifically on anonymity, privacy and security. Whonix provides security by isolation. It’s an operating system that explicitly uses the principle of isolation to enable security, privacy, and anonymity.

This operating system is developed by two major programs. One is a workstation, and the other one is Gateway. The gateway acts as a middleman here, and it forces all the connections to go through the Tor network. So there is no opportunity for the IP address to be leaked, which is how the Whonix OS keeps you secured.

Download Whonix

6. Discreete Linux

Maybe you are trying to keep your data safe and yet find out any better security distro for your Linux Operating System. Let your scare fly away. Here you have Discreete Linux OS, called one of the most secure Linux distros to protect your valuable data.

This OS doesn’t connect with the internet while working, which separates the Data & cryptographic keys to be protected from the non-trusted network. Another exciting thing is that this OS is a pure live system, so you don’t need to install it on your computer; instead, you can quickly run it with a USB stick.

Download Discreete Linux

7. Linux Kodachi

Do you love to stay fully anonymous while surfing the internet? Then Kodachi Linux is one of the best, most secure Linux distros that you would love to have. Many users are saying that this is the most secure Linux distro that they have ever had. Personally, I have never tested, though. This Operating System comes with Tor, a VPN, and DNSCrypt and can be booted easily from a DVD or USB drive.

kodachi Linux

You can choose the exit routes country whenever you surf the internet. This operating contains many other useful applications like Pidgin internet messenger, Transmission, VirtualBox, Geany, FileZilla, and many more. Finally, I must say, this Operating System comes with everything that a user needs to be secured.

Download Linux Kodachi

8. BlackArch Linux

BlackArck Linux is a new Linux security distro designed, especially focusing on Pen Testing and Security research. It comes up with a vast number of tools that are twice even thrice as more than Kali Linux has.

This is straight Out Of The Box. They can be installed separately, or if you want, you can install them in a group as well. This operating system is straightforward to use. This OS is lightweight enough so you can run it in any hardware.

Download BlackArch Linux

9. Heads OS

Heads is a GNU/Linux-based free security distro. This OS is significantly smaller than the other OS out there and pretty easier to manage. Heads use only free software that means this OS gives more value to users’ freedom and community.

heads OS

Like the other OS above, Heads also uses Tor so that you can be anonymized while surfing online. All of your traffics are forced to go through Tor by default, but they give the option to make it stop if you want. Heads always give priority to their users.

Download Heads OS

10. Subgraph OS

Like Tails, the Subgraph Operating system is also a Debian-based operating system that prevents the surveillance and interference by sophisticated adversaries from the Internet. This OS is designed for everyone. Its GNOME-based desktop environment is incredibly user-friendly.

While talking about security & privacy, this security distro prevents the attack through intelligent access control; memory corruption-based exploit prevention with a package of patchset (grsecurity patchset and Pax). Grsecurity patchset provides a package of security, such as addressing space protection, enhanced auditing, and process control.

Download Subgraph OS

11. IprediaOS

This security distro is good to browse the web, email, chat, and share any files through the internet anonymously. All of the connections are routed to go through I2P software.

Unlike some other distro out there, IprediaOS supports TORRENTS. This Operating System is competitively fast than Tor even you are going to use it on your older computer, and this OS will work well on that as well.

Download IprediaOS

12. PureOS

If you are looking for a user-friendly security distro that will allow you the freedom to modify it. Then PureOS is that one. PureOS is free software that delivers a security package, including the “Duck Duck Go” search engine.

pureosIt will protect your privacy by avoiding personal search results as it’s free software, so you can download it without purchasing anything. You can ask for its source code even you are allowed to modify it as well.

Download PureOS

13. Openwall GNU/*/Linux

Openwall is a security-enhanced Linux distro-based operating system that is specially designed for servers and Applications. Openwall provides security by reducing the flaws in its software components with the Openwall patch (Best known as a (non-exec stack patch). It’s a free intended server platform.

Download Openwall GNU/*/Linux

14. Alpine Linux

Alpine Linux is a mus libc, and BusyBox based most secure Linux distro. It is so lightweight that you can ever think. The size of its base system is around 5 MB which is smaller than the other systems available out there. And this is why this Linux distro is that much popular.

Its other component BusyBox includes a lot of tools, and very few of them are bunzip2,bzip2, less, lzma, unlzma, vi, wget. Those tools are in an Alpine base image that is not in Debian base image. Its application manager APK is way faster than others and very easy to use.

Download Alpine Linux

15. Container Linux (Formerly CoreOS)

If you love to serve on various machines and update machines without any downtime, then Container Linux (Formerly CoreOS) will be your go-to Linux distro. Container Linux is a lightweight Linux Distro which is designed for clusters and server. This security distro is getting popular nowadays because it’s easy to deploy, manage, and run containers. In earlier, CoreOS supported only the Dockers platform, but recently it supports rkt (Rocket) as an alternative to Docker. This software updates automatically when they need to be updated, which improves security.

The Last Words

Here I have reviewed the 15 Most Secure Linux Distros available out there, some of which I have tested personally. The rest I have ranked by exploring the best features from their website, researching the internet, and gathering reviews.

So I hope you will find this article helpful in choosing the best one for yourself. If it does so, please share it on your social media with your friends and family trying to have the best one for themselves. And also, don’t forget to leave your valuable suggestion in the comment box.


  1. Hello

    My name is Chris and I had nothing to do with IT and security two years ago. A typically Windows using stupid guy. But since some time, I get at least three VPN’s since I found the best for me NORDVPN… But now I do have bought an ACER Nitro with 16gb RAM and a NVIDIA GeForce GTX , AMD Ryzen 7 and so on… BUT I DO NOT WANT TO STAY ONE MINUTE MORE with WINDOWS…
    So, I do need help, beeing a “newbe” in Linux things. I want a SAFE / SECURE / ANONYMOUS distro, but easy to install and run with a “beautiful” DESKTOP and I can work with it and install my two or three softwares I do pay for like, a private Mail-Server I can really recommend….

    I DO TRIED KODACHI, but there where ALL times difficulties with it and after I could read here… NO WAY.


    A Linux that I can run my GEFORCE GTX (I am not a gamer, but not having TV at home, I do look documentations and also good movies and I also bought an ACER with WQHD 2560 x 1440 I want to exploit and I do have enough place, 1000gb SSD.

    I also do hear about security packages like pfsense or IPFire to install on every Linux OS – but I really want to be 101% anonymous and safe from FACEBOOK & GOOGLE & F…. Co.

    SO, IS THERE ANYONE WHO WANTS TO HELP ME WITH TIPPS AND SO ON ?? I would be very, very gratefoul !!!

  2. I have tried out kodachi and have found it to be highly secure and i am able to lock ports down when not needed.

  3. No matter what system you choose for your intended purpose there is a common downfall demoninator: the operator-you, me, whoever is using the system. Personally I use tails for browing and sending end to end encrypted files. My main goal is anonymity and security. Without privacy we have neither.

  4. I used to mess with Debian on an old… well not that old as it’s processor could likely give my current (granted refurbished,) laptop a run for its money. O do like what purism offers with their hardware. Unfortunately, I am finding that much of the PureOS seems to have bundled into it very ancient software. While that is in and of itself not necessarily a BAD thing, it does make me wonder if perhaps doing both the hardware and software may be causing both to not be as good as they could be. Since so many are working on GNU / Linux perhaps they may provide the best solution by focusing on open source hardware?

  5. you are missing the new Astralinux, fly is by far best desktop and file explorer experience I’ve ever had, it’s hardened by code and it was made from scratch, I have it on all my computers

  6. Subgraph OS deserves #1 easy to install and safe. Qubes is a great contender. rest is not even in the same league. But although not mentioned openSUSE Tumbleweed can be set up easy and secure too. For most starting Linux users concerned about security openSUSE Tumbleweed is already a leap forward and very easy to handle (especially when the user comes from a windows environment).

  7. Have downloaded and burned to cd/dvd – numbers 2,4,6,8,9,11 and found some are old outdated versions,Firefox is like version 49-57,or if FF ESR or Quantum is still outdated.Tails and Heads are okay as Live CDs,didn’t have user name and password for BlackArch, and when I finally got it, it wouldn’t run or install to HDD,subgraph said no hardware detected and no network card seen, so no Internet access, Ipredia OS was either old as or it was only 64 bit able,Subgraph OS and Discreet OS just didn’t run, install, or no hardware detected so no network card seen, so no Internet access.

    Kodachi – the most secure,has full protection , a free VPN … But if you go and look at the wrong website or download something from a torrent site, they may van you from their network,therefore pulling the plug on your free VPN protection, IP address hiding.Only indication is flashing red “You’ve been banned from our network” warning,no reason told you unless you contact the provider by email. Will try Parrot OS, but think I have before, and it was okay.
    Qubes looks good, but i couldn’t be bothered setting up the gateway then the workstation. Open OS firewall ran, but thats all.My try Pure and Alpine and see if they’re good.

  8. Kali Linux is actually one of the LEAST secure distros, since every session gives you root privileges without a password. This means that it’s easier to execute commands quickly, but it also poses a major security risk. Kali is specifically designed to attack OTHER computers to test them for security flaws. If you want a good pen-testing distro that you also want to use as your main distro, consider Parrot Security.

    • I was just getting ready to leave a comment also about that very thing. I think that the author used a very biased non objective view when writing opinion for #4. Great for hacking and very user friendly as opposed to Black Arch, CAINE, NST, and some of the more complicated ones like that that are hard to install and then do nothing but run, no complications. But Kali and the others I mentioned are pentesting distros, offensive and created with less emphasis on everyday user desktop security, Kali doesnt even come with TOR or AnonSurf ( Parrot Does ). I use Kali all of the time, I love it, but I personally think Parrot is better and Im liking Tsurgi also for its forensic tool set, Crypto coin, Forensic Imaging, Disk Forensics and many more, far more than what Kali has and retains some user friendliness on top of everything. A really nice OSINT suite also, with TOR available. I think of all the distros in this list for anyone who doesnt know very much about how to use Linux and reading this, youre better off just using Ubuntu and going from there… If youre coming from Windows then your already more secure out of the box plus its EXTREMELY user friendly, you dont have to use the terminal if youre non comfortable with it. Other than that I wouldnt try anything on this list except for Tails, Heads or Whonix and thats it or even Parrot cause I have a personal bias for recommending it. I myself have always wanted to try Whonix, I would have that as #1 then Heads/Tails and then Parrot and end the list there because all the rest either are pentesting platforms or just dont work or arent updated regularly or at all…… So anyone looking to try a secure Linux there you have it. The poster that I made this reply behind is right about Kali and probably would say similar to what I did here if he/she felt like typing so much lol…

      • “youre better off just using Ubuntu”

        I strongly advise against the use of Ubuntu for anyone concerned about privacy as it unfortunately has a history of data mining and other privacy/security related issues. If you look into its history, and even more recently, there’s a lot of warranted criticism. Most major distros like Mint switched from Ubuntu to Debian for good reason.

  9. Linux Kodachi would have been on the top if you have tested it I use to use tails but since I found Kodachi I say its the best when it comes to privacy and anonymity no one can beat it period.

    • Kodachi steals your resources by mining litecoin in the background, then sends the hashes back to the devs. Not sure if id trust a distro that does that… I guess if the CLEARLY allowed opting out i would maybe understand

  10. WOW! A lot to learn.
    I am new to Linux.
    I just bought a book, about Ubuntu.
    I am looking for high security, in all areas.
    I am a researcher, Investor, and I do some writing on a small scale and still learning to type, HA HA!
    I was a diesel Tec and an Instructor.
    Thank You, so very much!!

  11. You forgot the most secure of them all, Gentoo. Compiling executables from source and removing support for things that you do not need,extra languages, whittle out the kernel as only you need it, the list is quite extensive for it. That means a lot less for a hacker to utilize to get into your system. That and it has incremental updates. So you’re always at the latest but fixes and features.
    Sad that this one did not get mentioned. It would truly be at the top of them all.

      • I would say so. Do you (Jonathon) know how to build a systemd platform from scratch? Do you believe that Windows is more secure than Qube OS? Remember that in one case you depend on the perfection of systemd (almost 100% Red Hat) and in the other case you depend on the perfection of the Windows 10 kernel (almost 100% Microsoft).

        Distributed development of critical software elements is crucial for a secure OS (IMHO), but if you ignore that requirement, like most of the world, then I would recommend you use Chrome OS with Linux and/or Windows in VMs. Chrome OS is about as inherently secure as Windows or Fedora (Qubes) and probably has more open source code as Fedora. And provides a simpler VM architecture, so it’s less likely to be hackable.

        But you might disagree on almost all those counts.

        • Compiling software by yourself doesn’t make it safe. Isolated virtualization of apps remove many attack vectors, however.
