guide to vpn protocols

You don’t need to know how a VPN works to use a VPN. But if you’ve ever checked the settings on your ExpressVPN app, you’ll see a tab called Protocol.

Protocols are methods by which your device connects to ExpressVPN’s secure servers. By default, ExpressVPN automatically uses the protocol best-suited to your network, but you can also configure your app to use other protocols: PPTP, OpenVPN, or L2TP/IPsec. Here’s a guide to what they mean and how they’re different:

What is PPTP?

PPTP, or Point-to-Point Tunneling Protocol, is one of the oldest protocols for implementing a VPN. It’s been around since Windows 95. Out of all the protocols, PPTP is one of the most common, easiest to set up, and computationally fastest. It’s also easy to crack and offers virtually no security benefits.

PPTP is useful on slower devices like routers, when security is not an issue.

What is L2TP/IPsec?

L2TP stands for Layer 2 Tunnel Protocol, and by itself it doesn’t offer encryption. Because of this it is often paired with an encryption protocol called IPsec (Internet Protocol Security). Together they provide a level of security superior to PPTP but with the same ease of set-up.

While more secure than PPTP, L2TP offers only limited security benefits and should be used only for anonymization purposes or for changing VPN locations.

What is OpenVPN (with TCP/UDP)?

OpenVPN is a newer and more configurable protocol. ExpressVPN’s version supports both UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) ports. UDP is generally faster but TCP has a greater chance of bypassing firewalls. ExpressVPN uses UDP by default unless it is blocked.

The best thing about OpenVPN is that it’s open source. “Open” may not sound like a good thing for a privacy tool, but it’s actually a huge advantage. If there are any security flaws in the code—and as yet none are known—they will be quickly identified by the open source community. Paired with a strong encryption algorithm, OpenVPN is one of the most secure VPN protocols available.

  1. Does not work on MAC OS (I have MAC book PRO High Sierra) and get the message to send error code, but cannot send, because it will not open its own VPN page. If it worked, then I would go back to it.

  2. I tried to log in today to configuring my phone and was told they didn’t recognize me as a custumer , then my phone wouldn’t text and we were cut off , help ,

  3. I am in Shanghai, and i can’t connect my vpn (on my phone or on my computer) to paris or another location . The connection starts then after a will it’ s failed. I try with TCP , L2TP but nothing was good. Can you help me . I really have to be able to go on the internet

    1. Hi, Wardell,
      You can use the VPN when connected to any Wi-Fi network, or when you are connected to the Internet via an ethernet cable. Hope this helps!
