I also use Nord. I think it’s fine, but self-hosted and open would be better (since you for SURE know what data is passing through and what is happening with it). With Nord it’s like a “trust me bro” black box.
That said, I trust Nord enough for my needs. I don’t do anything too secretive on the VPN and frankly I think the 80/20 is in favor of just using Nord over self-hosting (I don’t really have time for that).
Your mileage may definitely vary haha, I use that feature a lot (I’m lucky / unlucky enough to work with a lot of new technologies)
