SlickVPN Offers you a wide range of protocols that offer different levels of security, dependent on the device and needs you may have. SlickVPN members can connect to our secured encrypted tunnels from your device to our servers using any one of these protocols. The technical differences between them are outlined below. We recommend that members use the SlickVPN client, which uses the OpenVPN protocol, on your Windows and OSX computers, for the fastest and most secure connections.

Encryption Level




Supported OS

Desktops, laptops, tablets and other mobile devices.

Desktops, laptops, tablets and other mobile devices.

Desktops, laptops, tablets and other mobile devices.


Basic encryption up to 128bit. Most useful for geolocation as security is comprimised

Strong encryption. In addition, the data wraps IPsec up to 128bit.

Very strong 256 bit encryption.


Very fast due to the basic encryption

Great performance with minimal setup

Best performance. Very fast, even on connection with high delay


Very simple. The protocol built into most devices. Does not require additional software

Very simple. The protocol is built into iOS and OSX. Does not require additional software

SlickVPN client requires no configuration. Other methods require provided .ovpn file

SummaryBasic encryption up to 128bit.

The Point-to-Point Tunneling Protocol is one of the most widely used protocols uses on most devices today. The protocol itself has been known for some security flaws, although many have been addressed. This is especially useful for VoIP applications and mobile/portable devices with its 128-BIT encryption. Since the protocol is built into most devices, it does not require additional software to use it.

Intended for Apple devices, this protocol is a bit slower than others but offers a stable and secure connection. The cost of offering a more secure connection than PPTP, IPSEC is a bit slower than the other protocols and sometimes finds trouble with Firewalls, routers, modems and NAT passthroughs.

This option is the recommended protocol that we suggest to all our members.

This option offers a AES-256-CBC cipher which encrypts your connection securely. OpenVPN runs over multiple ports with both UDP and TCP connections.
