Top 10 most secure operating systems

The security of anything, even operating systems (SO), tends to be a difficult or even controversial topic to examine. The only truly secure operating systems are those who lack contact with the outside world (for example, the firmware of a DVD player).

As with any other operating system, they will inevitably have some type of vulnerability or weakness that can be exploited. In fact, any network operating system can be exposed if its configuration is carefully abused, no exceptions.

Anyway, here are the ten most secure operating systems on the planet nowadays. Another important fact is how quickly the vendor releases a patch when a vulnerability is discovered. Recently the most popular Bash shellshock and Openssl Heartbleed prove it.

List of the most secure operating systems

1. OpenBSD

By default, this is the most secure general purpose operating system out there. The proof in the pudding? The fact that it has suffered only two remote attack vulnerabilities in the last decade serves as strong evidence of its tight security and strict auditing policy.

Also, OpenBSD lacks a large enough attack surface (beware of running numerous web applications) for hackers to exploit.


Linux is a superior operating system. When customized, it can be configured as extremely secure. Linux has an impressive vulnerability patching policy.

There are different Linux distributions with more privacy-oriented functions, for example QubesOS It is a modified version based on Linux that has the peculiarity of creating single-use virtual machines to open files or browse the Internet.

3.Mac OSX

This Apple-made operating system handles user permissions better than, say, Windows XP, but it still packs an indecent amount of vulnerabilities and remote exploits into its systems. That, along with Apple's slow response to many of its security issues, has pushed this OS to the bottom of this list.

4. Windows Server 2008

Say what you want about the security of a Microsoft operating system; At a minimum, they know how to improve and have been through the worst security threats the Internet can present.

This iteration of Windows Server has improved backup and recovery, user account control, web server (IIS) role, and server role security settings.

5. Windows Server 2000

This operating system is so secure that it took almost a decade before Microsoft could come up with a better one. This operating system for network servers, laptops and corporate workstations continues to receive monthly security patches even after nine years since its release.

6. Windows 8

Microsoft tried to fix the security problems that have plagued Windows 95, 98, ME, and XP, but ended up alienating consumers.

The main complaints that people leveled against the polarized operating system—confusing security policies and lack of backwards compatibility—were actually security measures that were supposed to protect Vista much more from breaches and hackers. hackers.

7. Windows Server 2003

The good news is that Windows Server 2003 is still a more secure operating system than Windows XP.

The bad news is that when it comes to security, it's even worse than its previous prototype, Windows Server 2000. However, it does feature competent security enhancements like default disabling of vulnerable services and a built-in firewall.

8. Windows XP

It became one of the biggest and longest-running releases from Microsoft (mainly because Vista didn't connect with the general consumer base that uses Windows). Tragically, it's also one of the least secure operating systems of all time.

Because this operating system runs a lot of network services by default and allows users to access all privileges by default, it is also hacked and breached in one night. daily by default too.

9. HP-UX 11i

Although not one of the most commercially successful operating systems on the market today, this Unix-based Hewlett-Packard operating system has been included in this list due to its superior security policies over several more popular operating systems (namely Mac OSX, Solaris, and Linux).


This variant of Sun Microsystems Unix-OS is at the lower levels of the security hierarchy in this article because it is not inherently security-focused.

Also due to certain business-related circumstances, most of the Solaris source code has already been released through the OpenSolaris project.

final words

If your privacy and security is above all else, we recommend that you start using an operating system other than Windows, since it currently sends and collects thousands of user data in addition to being an easy target for attackers.

Using a secure operating system and an anonymous email service such as ProtonMail will significantly improve your privacy and security.
