Best VPN Promotions: Understanding PPTP VPN

What is PPTP VPN?

PPTP, or Point-to-Point Tunneling Protocol, is one of the oldest VPN protocols still in use today. Developed by Microsoft, it was initially introduced with Windows 95 to facilitate secure communication over the internet. PPTP VPN establishes a tunnel between a client and a server, encapsulating data packets to ensure privacy. This protocol is known for its ease of setup and compatibility with various operating systems, making it a popular choice for users seeking straightforward VPN functionality.

How Does PPTP VPN Work?

When you connect to a PPTP VPN, here's what happens behind the scenes:

The VPN client on your device initiates a connection with the VPN server. This involves authenticating your credentials to ensure you have access to the network.
Once authenticated, PPTP creates a 'tunnel' between your device and the server. This tunnel uses the Generic Routing Encapsulation (GRE) protocol to encapsulate the data packets, which means your data is wrapped in additional headers to travel through the internet securely.
PPTP employs the Microsoft Point-to-Point Encryption (MPPE) for encrypting the data. However, this encryption is considered relatively weak by today's standards, offering up to 128-bit encryption, which is less secure than newer protocols like OpenVPN or IKEv2.
The encapsulated and encrypted data then travels through this tunnel, making it difficult for outsiders to intercept or understand the data being transmitted.
Upon reaching the VPN server, the data is decrypted, and the server then forwards it to the intended destination on the internet. When responses come back, they are again encrypted and sent through the tunnel back to your device.

Advantages of Using PPTP VPN

Despite its age and security concerns, PPTP has several advantages:

Speed: PPTP is known for its fast connection speeds, which can be beneficial for streaming or large downloads where speed is more critical than top-tier security.
Wide Compatibility: It works seamlessly with almost all operating systems, including older versions, which makes it very accessible for a wide range of users.
Easy to Set Up: The configuration of PPTP is straightforward, often requiring just a few clicks in the network settings of most devices.
Resource Efficient: PPTP uses fewer system resources, which is advantageous for older or less powerful devices.

Limitations of PPTP VPN

However, there are significant drawbacks to consider:

Security Vulnerabilities: Over the years, multiple security flaws have been discovered in PPTP, making it less secure than other protocols. Its encryption has been cracked, and it's not recommended for highly sensitive information.
Outdated Encryption: The use of MPPE for encryption is not as robust as newer standards, making it susceptible to attacks.
Geographical Restrictions: In some regions, PPTP traffic might be blocked or restricted due to its known vulnerabilities.

Best VPN Promotions for PPTP Users

If you're considering using a PPTP VPN, here are some promotions from leading VPN services:

NordVPN: Offers a 70% discount on their 3-year plan, providing access to over 5,500 servers worldwide, although they primarily recommend other protocols for security reasons.
ExpressVPN: Known for speed, they currently have a deal offering 3 months free on a 12-month plan, but note that PPTP isn't their default choice due to security concerns.
CyberGhost: They have a special promotion where you get 79% off with an additional 2 months free, and they support PPTP, though again, they advocate for more secure options.
Surfshark: A great option for unlimited devices with a current promotion of 81% off and 2 months free on a 2-year plan. They provide PPTP alongside other protocols.
ProtonVPN: While focusing on privacy, they offer PPTP with their VPN Plus plan, currently with a 50% off annual subscription.

When choosing a VPN, consider not just the promotions but also the overall security features, server locations, and the provider's stance on privacy. While PPTP can be used for its speed and compatibility, for critical security needs, it might be prudent to opt for more secure protocols like OpenVPN or IKEv2.
