Both of these belong to Kape Technologies. Neither marketing site leads with it, though ExpressVPN names its parent in its own privacy policy, unprompted, which is more than most services in this market manage. ExpressVPN scores 3 for privacy and Private Internet Access scores 4, and from there they diverge about as far as two products under one owner can.
Where ExpressVPN wins
It is the fastest entry in this directory: 247 Mbps against a 1,078 Mbps line, where Private Internet Access managed 145 Mbps. If bulk throughput is what decides it, the comparison ends here.
Its kill switch held under testing. Private Internet Access's leaks unencrypted traffic after a system reboot, which is why the feature is recorded as absent for PIA rather than present.
On jurisdiction, ExpressVPN operates through a British Virgin Islands entity under BVI law, outside both intelligence-sharing arrangements. Private Internet Access is a United States company and therefore inside Five Eyes, which is the objection most readers raise first.
Where Private Internet Access wins
It publishes numbers. Its quarterly transparency report records four subpoenas, seven other government and civil requests, and six foreign or informal requests, with logs produced in none of them. It also states it was subpoenaed for user activity logs in 2016 and 2017. No other entry in this directory publishes anything comparable, and it is a stronger form of evidence than a jurisdiction claim.
Private Internet Access scores 4 for value against ExpressVPN's 2, and the reason is renewal behaviour. PIA's three-year plan is $79 and renews at $79. ExpressVPN charges $83.72 covering twenty-eight months and then renews at $99.95 a year. PIA also allows unlimited simultaneous connections against ExpressVPN's eight, publishes open-source clients, and supports port forwarding where ExpressVPN does not.
ExpressVPN's most recent locatable audit is from October 2022 — nearly four years old — and its own audit index returns errors.
Which should you choose?
Choose Private Internet Access if published evidence persuades you more than jurisdiction does, and you can treat its kill switch as absent. Choose ExpressVPN if speed is what you are buying and you want a working kill switch.
If the shared owner is itself the problem, Mullvad and Windscribe both score 4 for privacy, and neither has a corporate parent.

Comparison


NordVPN vs ExpressVPN
Both cost about the same and both renew at roughly triple. What separates them is how much of each no-logs claim an outside firm has checked.
Comparison


Private Internet Access vs IPVanish
Two United States services whose no-logs promises were both tested by real legal demands. One produced nothing. The other produced records.
Comparison


ExpressVPN vs PureVPN
Both are registered in the British Virgin Islands. One is the quickest connection you can buy; the other handed a customer's records to the FBI in 2017.
Comparison


Private Internet Access vs TunnelBear
Both cover unlimited devices and both kill switches leaked. Private Internet Access does far more; TunnelBear is easier and never changes its price.
Comparison


ExpressVPN vs Proton VPN
ExpressVPN is the quicker connection by a clear margin. Proton VPN is the one whose apps you can read and whose free tier never expires.
Comparison


Proton VPN vs Private Internet Access
Both publish their source. One is Swiss with a free tier you can stay on; the other is American, cheaper over three years, and owned by Kape.
