You won't have to spend much at all to get a far better VPN experience than Psiphon. Psiphon does have over 1000 servers at 20+ locations, but it doesn't consistently unblock any of the major streaming services most VPN users want access to. The open-source VPN offers a few advanced features like split tunneling but doesn't offer VPN basics like a kill switch. When using Psiphon's proxy or VPN servers, there are no guarantees that your digital privacy will be protected.
Psiphon VPN: This basic VPN service uses AES-256-bit encryption and claims to protect user traffic, but isn't very good for privacy at all.
