Today, most of us know about virtual private networks (VPNs). Many businesses use VPNs to stay secure and private while transferring corporate data, or to enable employees to connect to the office servers remotely. Many individuals also utilize VPNs to overcome their country’s restrictive firewalls or to bypass geographical limitations to access their favorite online streaming channels or social media websites.
In this article, we will explore the differences between PPTP VPN & L2TP VPN protocols so that you can decide which one is the better choice for your needs. Note that each protocol has significant advantages and disadvantages – generally related to the level of encryption, device compatibility and their ease of use configuration.
What is PPTP Protocol?
PPTP or Point-to-Point Tunneling Protocol is an outdated method for implementing VPNs. It is developed by Microsoft and the easiest protocol to configure. PPTP VPN has low overhead and that makes it faster than other VPN protocols.
With its use, users can remotely access corporate networks from any Internet Service Provider (ISP) that supports the protocol. PPTP VPN encrypts data using 128-bit encryption which makes it the fastest but the weakest in terms of security.
What is L2TP Protocol?
L2TP or Layer 2 Tunneling Protocol (L2TP) is the result of a partnership between Cisco and Microsoft. It was created to provide a more secure VPN protocol than PPTP. L2TP VPN protocol is a tunneling protocol like PPTP that allows users to access the common network remotely.
L2TP VPN Protocol is a combined protocol that has all the features of PPTP, but runs over a faster transport protocol (UDP) thus making it more firewall friendly. L2TP VPN protocol encrypts data using 256-bit encryption and therefore uses more CPU resources than PPTP. However, the increased overhead required to manage this security protocol makes it perform slower than PPTP.
PPTP vs L2TP Comparison
Since we’re talking about PPTP And L2TP Protocols, let’s take a look at a comparison between the two. So, here’s the differences between PPTP vs L2TP:
|Basic Info||Basic & first VPN protocol supported by Windows.||Tunneling protocol that uses IPSec for security/encryption and works via UDP.|
|Compatibility||Built-in support for a wide array of desktops, mobile devices, and tablets.||Built-in support for a wide array of desktops, mobile devices, and tablets.|
|Encryption||128 bit keys||256 bit keys|
|Usage||via device/OS built-in client, using username + password + server address||via device/OS built-in client, using username + password + server address and pre-shared-key|
|Stability||Comparatively unstable, but very stable and accepted by most Wi-Fi hotspots.||Proven stable on various kinds of devices, networks and operating systems|
|Supported Devices/OS||Windows, Mac OSX, Linux, iOS, Android, DD-WRT, etc.||Windows, Mac OSX, Linux, iOS, Android, DD-WRT, etc.|
|Security||Basic encryption||Very secure. Data integrity checking, encapsulates data twice.|
|Advantages||Easy setup/configuration, good speeds, supported by a large number of devices.||Easy setup/configuration, easily bypasses restrictions by networks or ISPs.|
|Disadvantages||Stability may vary depending on network. Does not offer government level security. Easy to be blocked.||Slower Speeds|
|Conclusion||PPTP is easy to setup and use with decent speeds. Less secure than other VPN protocols.||L2TP usually achieves lower speeds than other protocols, but its ability to bypass network restrictions and strong security make it a good choice.|
Summary about PPTP And L2TP Protocols:
PPTP VPN is easy to setup and use with faster speeds, but can result in a less secure connection. L2TP VPN, on the other hand, has lower speeds than other protocols, but offers stronger security which makes it a good choice.
