In case any PureOS people are reading this, consider making the info on PureOS security in your wiki easier to find.
You say in your blog post to "See the PureOS wiki to learn more about the extensive security features in PureOS." You link to your wiki's front page[1], but the word "security" is nowhere to be found on that page.
And if you click through to the only page that seems like it might have section on security, the "Overview and some general information about PureOS" [2], the word "security" is nowhere on that page either.
I'm still not clear where in the wiki this info is, but the security features and defaults are one of the most interesting things to me about an OS.
