As a professional security advisor, I am always asked what smartphone, OS, and apps provide the best security.

The answer to this question is simple yet complicated, and my answer is The Liberty or Librem 5 smartphones running PureOS by Purism.

To understand why Purism smartphones with PureOS are secure, one must understand the difference between PureOS and Android OS, Apple iOS, and Microsoft Windows.

The real difference comes down to control. Do you give up control and suffer consumer oppression and loss of your privacy or do you want to retain control and have consumer freedom and your privacy.

Forced Participation – Consumer Oppression and Exploitation

Android OS, Apple iOS, and Microsoft Windows operating systems participate and propagate the targeted advertising business model.

This simply means that these popular operating systems support intrusive apps that enable to the developer to monitor, track, and data mine the end user for financial gain.

This means that the app developer collects, uses, and sells the operating system end user’s personal and business information to advertisers, and in some cases to other third-parties that could include data brokers.

Apps developed for the Android OS, Apple iOS, or Microsoft Windows are tantamount to “Legal Malware” enabling the developer to conduct audio, video, and physical surveillance on the end user while data mining over 5,000 highly confidential data points associated with the end user’s personal, business, medical, legal, employment, biometric, and location information to exploit for financial gain.

When a consumer purchases a smartphone running Android OS or purchases an Apple iPhone, or a tablet PC running Microsoft Windows, the product owner is forced to click on “I Agree” to accept a predatory contract (terms of service) of adhesion (take it or leave it) or the product owner cannot use the smartphone even though the product owner paid for the product.

The predatory terms of service enables Google, Apple, and Microsoft, plus the preinstalled app developers such as Meta (Facebook), ByteDance (TikTok), or Amazon, to conduct surveillance on the end user for whatever purpose those companies and developers desire.

Basically, the operating system end user is forced participate within a highly intrusive business model centered on Surveillance Capitalism where the OS end user is exploited for profits at the expense of privacy and security by numerous multinational corporations responsible for the development of the OS and apps.

Freedom of Choice- Consumer Liberation

PureOS is a non-Android convergent Linux kernel based operating system that supports apps that can be peer-reviewed to avoid the targeted advertising business model.

This means that there are no threats to the PureOS end user’s privacy nor security.

As a matter of fact the PureOS end user is not required to click away their privacy or security when they purchase a Librem 5 or Liberty smartphone or any other laptop PC, mini-PC, server, or tablet PC manufactured by Purism.

This means the product owner can simply start using their smartphone or PC immediately after they purchase the product without having to click on “I Agree”.

Furthermore, the Liberty Smartphone is manufactured at the US based Purism facility with “Made in USA Electronics” for end-to-end security and a secure supply chain.

PureOS is a true convergent operating system which means that the OS is no different on a PC or smartphone, this means that the Liberm 5 or Liberty smartphones are equal to a powerful quad core arm-based desktop PC.

Purism returns freedom, privacy, security, and control over the smartphone or PC back to the product owner the way it should be.

Enclosed below is a comparison chart showing the advantages of owning a Purism smartphone, tablet PC, laptop PC, mini-PC, or server supported by PureOS:
