Some experts have voiced concerns that the protocol might have been weakened or compromised by the NSA, though. Yes, L2TP/IPSec has no known major vulnerabilities. The average user probably won’t notice a difference in speed between the two. There’s some debate out there about whether it’s faster than OpenVPN or not. L2TP was developed by Cisco and Microsoft in the 90s.Īccessing the internet through a VPN when security and privacy are concerns. Layer 2 Tunnel Protocol is the VPN protocol, and it’s usually paired with IPSec for security. In those cases, OpenVPN usually requires no manual configuration, as the provider’s app takes care of that for you. Many native VPN clients from consumer VPN providers, however, make it much easier to install and run. If you plan on setting it up manually, no. It supports several encryption algorithms, the most common being AES and Blowfish. Because it can be configured to use any port, it can easily be disguised as normal internet traffic and is therefore very difficult to block. OpenVPN uses a custom security protocol that relies heavily on OpenSSL, similar to the encryption used on HTTPS websites. Not as fast as PPTP, about the same speed as L2TP depending on the device and configuration. It’s become increasingly mainstream for general purpose VPN use, and is now the default protocol used by most paid VPN providers. Third-party VPN clients often utilize the OpenVPN protocol, as OpenVPN isn’t built into computers and mobile devices. OpenVPN is one of the newer protocols with an initial release in 2001. Only use open-source and professionally audited custom protocolsĪn open-source VPN protocol that’s highly configurable for a variety of ports and encryption types.Wireguard is a newer protocol that promises to be faster and more efficient, but has some privacy drawbacks.IKEv2 is a fast and secure alternative for devices that support it, particularly mobile devices.SSTP is also a solid option for Windows users, assuming you trust proprietary tech from Microsoft.L2TP/IPSec is probably the most widely available alternative that offers decent security.OpenVPN is always a solid option, especially when the setup is handled by a third-party app. For those who want a quick answer as to which one they should use: This is a quick reference guide for the lay-person who wants to explore the different VPN protocols available.
