Thank you, I've updated the link. Let me know if you'd like to hear more about the security features and I can get Kyle (security) and Jeremiah (PureOS) to jump into this thread.
Instead of having Kyle & Jeremiah elaborate on it in this thread, which will quickly disappear into the aether, probably better to elaborate on it in your wiki. PureOS’s main customer base are techies and hackers who will be very curious about security, and a thorough writeup on it could be a strong selling point.
