QuickConnect makes your NAS wide open to internet. It does so using UPnP or a relay station in a synology data center. Not only Stnology will likely have access to users data at the relay station (see change of certificate!), DSM login page will be open to anyone on internet (you can try random usernames on https://quickconnect.to/ https://quickconnect.to/ and connect to people’s NASes). Maybe for routers it’s different, but this service is not secure for NAS.
