PureOS is not vastly different than other GNU/Linux distributions, except in the following ways:

#. PureOS does *NOT* include any non-free proprietary software or firmware (aka *binary blobs*).
#. PureOS is pre-configured with privacy and security in mind. PureOS along with additional technologies like PureBoot implement security-in-depth which aims to provide multiple layers of secure computing to protect both data at rest and data in transit.
