PureOS vs Red Hat Enterprise Linux

PureBrowser is a modified version of Firefox that comes with security focused plugins. There is also a copy of TOR installed in the OS by default.

PureOS is available from their site for free for anyone to use, no need to purchase any of their laptops in order to check out the OS which is a tweaked build of the Trisquel distro.

PureOS is the default OS installed on the Purism Librem laptops.

Each released version of RHEL is supported for around ten years by Red Hat with constant bug fixes and security updates.

RHEL favours stability over being up-to date. For this reason it ships with packages that may be up to two years behind in order to ensure stability over everything else.

Using older versions for packages means that they have been thoroughly tested and used in production for quite some time, and are ensured to play well with each-other.

This strategy has paid off quite a lot in the past. One example is the Heartbleed bug which left RHEL unaffected since it was using a two-year old OpenSSL library which did not have the bug.

RHEL has several built-in solutions for disaster recovery. For example, it comes with pacemaker which can be configured to manage multi-site and and stretch clusters across multiple geographical locations for disaster recovery and scalability. It can also be configured to trigger notifications when the status of a managed cluster changes by using enhanced pacemaker alerts.

Since RHEL backports all updates and bug fixes to older versions in order to maintain package compatibility across releases, applications hosted on Red Hat Linux don't have to worry about potential breaking changes in libraries they use, especially language libraries.

This distro is by far the one with the largest number of certified server-class hardware.

Comes with built-in management tools for containers (Atomic CLI, Cockpit) and a container runtime in the form of Docker engine.
