What our measurements show

Neither list gives server addresses, so no location of either provider can be measured.
ExpressVPN's list shows which locations are virtual: 104 of 226. Proton VPN's list has no such field, so it does not tell you whether any of its locations are virtual.
On a first visit, ExpressVPN's home page loads 5 advertising or analytics services and Proton VPN's loads 0, before anything is clicked.

From our own data: the server lists we read, our measurements, and our check of each home page. Apps, speed, and streaming are not tested.²

Country by country

Each row is a country that both providers list. In each of them, at least one provider has a measured location or both use the same network. The status comes from our own measurement of the server address each provider publishes. “Within … km” means the server is at most that far from the listed country.
