What is L2TP?
L2TP, also called Layer 2 Tunneling Protocol, is a tunneling protocol used to create VPN connections. Its main purpose is to securely transport data over public networks. However, to ensure VPN functionality and the protection of data, L2TP incorporates IPSec, which provides the necessary encryption and confidentiality measures.
Is L2TP secure?
While L2TP alone lacks encryption and security mechanisms, even L2TP/IPSec is now considered outdated. To prioritize stronger security, PureVPN no longer offers L2TP/IPSec as an option in its apps.
L2TP VPN Pros
L2T is compatible with most operating systems and supported natively by many devices. It offers better security than the outdated PPTP protocol, providing a more secure option for users.
L2TP VPN Cons
L2TP relies on IPSec for encryption and uses poor authentication measures. It may result in slower connection speeds due to the encapsulation process. There have also been concerns about the compromise of L2TP by the NSA.
Key Features of L2TP VPN
Other VPN Protocols
WireGuard is a lightweight and fast VPN protocol known for its modern encryption. It offers exceptional performance and simplicity, making it a popular choice for secure connections on various platforms.
SSTP, developed by Microsoft, provides secure VPN connections over HTTPS. It is primarily used by Windows users, offering enhanced security and compatibility for reliable encrypted connections.
OpenVPN is a highly configurable VPN protocol known for its robust security and cross-platform compatibility. It is widely adopted and offers flexibility in VPN setups, providing strong encryption and reliable connections.
IKEv2 is a secure and efficient VPN protocol suitable for mobile devices, ensuring quick reconnects after network disruptions. It offers strong security features and is widely supported.
IPSec is a widely used VPN protocol suite that offers strong encryption and authentication mechanisms. It ensures the privacy and integrity of data transmissions, and is commonly used alongside IKEv2 and L2TP.
Since it does not provide strong authentication, L2TP is used with IPSec for security. Though it may conflict with some firewalls, it is a great alternative to the OpenVPN protocol because it supports all modern platforms, and can get around ISP/network limitations.
