Re security: we do have e2e encryption; if you have a moment, take a look at our security brief under our FAQ https://pragli.com/blog/faq/ and let me know what you feel we should add / how we should display it.
Re Discord: I'm a gamer so I understand why you like it. Where I feel Discord is lacking in the workplace is that it only shows if you're playing a game, and it doesn't build any more sense of availability beyond that. It doesn't have the same auto-status / Spotify / manual status that we built into Pragli. It does for games (shows if I'm playing some game) but not for work.
