15 Most Secure Linux Distros for Privacy and Security Concern Users

So you are a Linux user and looking for the Most Secure Linux Distro to be secured and to 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 which 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 into 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 best and most secure Linux distros for your system.

Top 15 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 list of the Most Secure Linux Distros which are ’Specially Focused on Linux security.’ That means this article is done especially by focusing on Sharp Security that a Linux user is more concern 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 which 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.

2. Tails


Tails is 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 on personal computers. If you are looking for an OS which will keep you safe while browsing the internet, then Tails will take the first place.

tails

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 so it allows you to use the internet anonymously and whatever you do it never leaves any trace behind.

Tails OS doesn’t use any space of hard disk; 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 a DVD. However, there are some issues with this OS. Recently most of the users are claiming that Tails requires 2 USB stick while installing which is boring.

3. Parrot Security OS


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

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

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 which uses explicitly 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 connection to go through the Tor network. So there is no opportunity for the IP address to be leaked, and this is how the Whonix OS keeps you secured.

  1. 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

  2. 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).

  3. 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.

  4. 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.

  5. 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

  6. 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!!

  7. 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.
