Public Wi-Fi is convenient, but I would never assume a network is safe simply because it asks for a password before you can connect.
A hotel, airport, coffee shop, or conference network does not give you the same level of control as a network you manage yourself. Using a VPN can add another layer of protection, but only if you remember to connect it.
That is why encryption alone is not enough for me when evaluating a VPN for public Wi-Fi. I also want it to connect automatically when I join a network.
A kill switch should prevent traffic from escaping if the VPN tunnel drops. The VPN should also reconnect quickly when a hotspot connection fails, or the device switches networks.
For this comparison, I evaluated Surfshark, ExpressVPN, Private Internet Access (PIA), hide.me, and CyberGhost. I reviewed each provider's current documentation and public Wi-Fi protections. I also considered available customer feedback, including G2 reviews when enough reviews were available to be useful.

Why public Wi-Fi requires more than VPN encryption
A VPN encrypts traffic between your device and the VPN server, but that protection only applies while the VPN is connected.
Devices can begin syncing email or running other background services as soon as they join a Wi-Fi network, potentially before the VPN is active. Public hotspots can also be unstable, creating another opportunity for traffic to fall back to the underlying connection if the VPN drops.
That is why I give Auto-connect and kill-switch capabilities more weight in this comparison. Auto-connect helps ensure the VPN is active when a device joins a network, while a kill switch blocks traffic if the VPN connection drops.
Why Auto-connect matters on public Wi-Fi
Auto-connect reduces the chance that a device uses public Wi-Fi before the VPN is active, removing the need to manually connect each time you join a network.
Some VPNs take this further with network-aware controls. PIA can distinguish open from protected Wi-Fi, while hide.me identifies secure and insecure networks. ExpressVPN offers trusted-network controls on Android, and CyberGhost provides Wi-Fi-specific rules on supported platforms.
Surfshark takes a broader approach by automatically connecting when a device detects Wi-Fi or Ethernet. These different implementations serve the same purpose by reducing reliance on users to activate the VPN themselves.
Why a kill switch matters on unstable networks
A kill switch blocks internet traffic if the VPN connection drops, preventing a device from falling back to an unprotected connection without the user realizing it.
Some VPNs provide even greater control. PIA's Advanced Kill Switch prevents internet access unless the VPN is connected, while hide.me's StealthGuard can restrict specific applications or the entire connection to VPN use.
These capabilities are useful on unstable public Wi-Fi, where the VPN connection may drop without warning.
How I evaluated these public Wi-Fi VPNs
I scored each VPN based on five areas that directly affect security and usability on public Wi-Fi.
Public Wi-Fi automation (30%): I evaluated whether the VPN can connect automatically and recognize different network types. Providers that can adjust their behavior based on the network detected received higher scores.
Connection and leak protection (25%): I examined kill switches and other safeguards designed to prevent traffic from bypassing the VPN if the connection drops.
Protocol and connection reliability (20%): I reviewed the protocols each VPN uses and how well it can maintain or restore protection as network conditions change.
Device coverage and flexibility (15%): I evaluated simultaneous connection limits and platform support, including whether important public Wi-Fi features are available across operating systems.
User experience and reputation (10%): I considered available online customer feedback about reliability and usability.
The final ratings reflect my editorial assessment based primarily on documented technical capabilities, with customer feedback providing additional context.
What should you look for in a public Wi-Fi VPN?
Start with automatic connection capabilities. Ideally, the VPN should recognize different network types and adjust its behavior accordingly.
A strong kill switch should prevent traffic from bypassing the VPN if the connection drops. Reliable reconnection is also important when moving between networks or dealing with inconsistent Wi-Fi.
Finally, check platform support. Features such as Auto-connect and network-specific rules can vary by operating system, so make sure the protections you want are available on the devices you actually use.
Frequently asked questions
What is the best VPN for public Wi-Fi?
