Ok, so it's an encrypted, open source whistle-blowing feature in their app / system.
The article is light on technical details but if it makes whistleblowing easier and safer than for example emailing their editors that's probably a good thing.

I think they are bundling this into their regular app, so they'd have to put every guardian read on the list😅
