With the end of [[https://en.wikipedia.org/wiki/Lavabit][Lavabit]], many security- and privacy-concerned people switched to ProtonMail. This is why ProtonMail security is relevant. The Conclusion chapter of the whitepaper starts with following paragraph: #+BEGIN_QUOTE Our findings, presented [here], constitute serious shortcomings in ProtonMail's cryptographic architecture that we believe should be urgently remedied. As it stands, ProtonMail does not meet its self-professed security goals when these are subjected to analysis. #+END_QUOTE The [[https://protonmail.com/blog/][ProtonMail blog]] does not list any reaction. However, they are pretty busy [[https://twitter.com/ProtonMail][with their Twitter account]] and refer to [[https://old.reddit.com/r/ProtonMail/comments/9yqxkh/an_analysis_of_the_protonmail_cryptographic/ea3g0hm/][this reddit thread]] where they discuss with Nadim.
