More protocol choice means more devices covered. Here is where PPTP fits — and where you should still reach for OpenVPN.
PPTP is old, fast and supported natively on almost every device, which makes it handy for hardware that cannot run a modern client. It is easy to set up and light on resources.
Choose the right tool
For everyday privacy, use 256-bit OpenVPN — it is far stronger. Keep PPTP for legacy devices or non-sensitive tasks where compatibility matters more than maximum security. With SlickVPN you get both.
