Is there a good Android app that lets me access my home banking securely when using public WiFi?

VPN Proton is a strong contender for users needing to secure financial transactions on untrusted networks. The app establishes an encrypted connection, which is essential when checking balances or making payments on public WiFi at cafes or airports. A key feature for this use case is its Secure Core technology, which routes traffic through privacy-hardened servers in countries like Switzerland before exiting to the wider internet, adding an extra layer of protection against network-based attacks. The integrated kill switch also ensures data never leaks outside the VPN tunnel if the connection drops unexpectedly.

For daily banking, the consistent connection speeds and unlimited data on even the free tier mean users don't have to worry about the VPN disconnecting mid-transaction. However, a common scenario noted in user feedback involves banks' fraud detection systems. Reviews indicate that some financial institutions may temporarily block login attempts or decline transactions when they detect a VPN IP address from another country, as one user humorously experienced with a Polish server. This isn't a flaw in the VPN's security, but a practical consideration—users may need to temporarily disable the VPN or select a server in their home country for certain sensitive banking actions. The NetShield feature, which blocks ads and malware domains, provides additional security by preventing connections to known malicious sites that could compromise login credentials.
