VPN Protocols: What You Need To Know

VPN protocols are the underlying technology that lets you securely connect to a remote server. They enable you to hide your actual location and communications from anyone trying to intercept them. This is especially important when using public Wi-Fi networks, since many of them are configured to track your activity. There are several popular VPN protocols, but the most common ones used today are OpenVPN and SSL VPN.


Types of VPN Protocols: PPTP, L2TP, SSTP, IKEv2, and OpenVPN:

There are a variety of VPN protocols available, but the most common are PPTP, L2TP, SSTP, IKEv2, and OpenVPN. PPTP is the oldest and most commonly used protocol. It’s generally considered to be less secure than other options because it uses MPPE (Microsoft Point-to-Point Encryption), which has been found to be vulnerable to attack. L2TP is more secure than PPTP because it uses IPSec encryption. SSTP is also considered to be a more secure option than PPTP and L2TP because it uses SSL 3.0 encryption. IKEv2 is a newer protocol that’s considered to be very secure and fast. It’s usually the preferred protocol for mobile devices because it’s able to automatically reconnect if the connection is lost.


How to Choose a VPN Protocol: Factors to Consider:

VPN protocols are the methods by which your device connects to a VPN server. There are a variety of protocols to choose from, each with its own benefits and drawbacks. PPTP, L2TP/IPSec, and OpenVPN are the most popular VPN protocols, but which one you should choose depends on your needs.


PPTP is the oldest and most commonly used VPN protocol. It is fast and simple to set up, but it is less secure than other options. L2TP/IPSec is more secure than PPTP, but can be more complicated to set up. OpenVPN is the most secure protocol, but it can also be more difficult to configure than the others.

Consider your security needs when choosing a VPN protocol. If you need a high level of security, OpenVPN is your best option.

PPTP:

PPTP is a common, fast, and secure protocol used to create VPN tunnels. It is available on most platforms and can be used with a variety of authentication methods. PPTP has several known security vulnerabilities, however, and should not be considered a silver bullet for security.


L2TP

L2TP is a technology used to create a VPN tunnel. It is an extension of the Point-to-Point Tunneling Protocol (PPTP) and can be used to create a secure connection over an insecure network. L2TP uses a combination of IPsec and MPLS to provide security and tunneling. L2TP is often used in conjunction with IPSec, which provides authentication, encryption, and integrity protection.


SSTP

Secure Socket Tunneling Protocol (SSTP) is a Microsoft proprietary VPN protocol. It uses Secure Socket Layer (SSL)/Transport Layer Security (TLS) protocols to create a secure tunnel. Traffic passing through the tunnel is encrypted, so it is less likely to be monitored by third parties. SSTP can be used to connect to a Microsoft Windows Server 2003 or 2008 from a remote location, or to connect to a private network from the Internet.


IKEv2

IKEv2 is a newer, more secure version of the IKE protocol that was designed to overcome some of the shortcomings of IKEv1. IKEv2 includes support for key exchange, authentication, and encryption using both symmetric and asymmetric keys. It also includes a built-in mechanism for automatically reconfiguring IPsec tunnels when network conditions change.


OpenVPN

OpenVPN is a secure, open source virtual private network (VPN) software that lets you create a secure connection to another network over the Internet. It can be used to connect your home or office network to a remote server, allowing you to access files and resources on the other network as if you were on-site. OpenVPN is also widely used by businesses to allow employees to connect to their company’s network remotely.


Conclusion

In conclusion, VPN protocols are important to know for both personal and professional use. They provide a secure connection to the internet and can be used for a variety of purposes. There are a variety of VPN protocols available, each with their own strengths and weaknesses. It is important to choose the right protocol for the task at hand to ensure the best possible experience. Smarters VPN only use trusted, open-source VPN protocols like openVPN, ikev2 and WireGuard.
