Protocols
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.
| PPTP | IPsec | OpenVPN | |
|---|---|---|---|
| Encryption Level | We’ve stopped supporting PPTP connections due to the significant security flaws in the protocol. | 128Bit | 256Bit |
| Supported OS |
|
| |
| Compatibility | Desktops, laptops, tablets and other mobile devices. | Desktops, laptops, tablets and other mobile devices. | |
| Security | Strong encryption. In addition, the data wraps IPsec up to 128bit. | Very strong 256 bit encryption. | |
| Speed | Great performance with minimal setup | Best performance. Very fast, even on connection with high delay | |
| Configuration | 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. | 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. |
