People are talking about secure alternative matrix/riot, mattermost, zullip... not that i have anything to do with them but Wire https://wire.com https://wire.com is pretty impressive (you can geek out on haskell backend). In small org we have been using riot/matrix and it is great. Works well but it is more like modern IRC. It doesnt have too much ui sugar. Mattermost on the other hand looks cool but had slow clients and there was some bullshit with push notifications requireing some enterprise server license. Hope its no longer the case - i mean why would you want chat without notifications?
