Choosing the Right VPN: OpenVPN vs PPTP

Introduction to

OpenVPN and

PPTP

As we become increasingly reliant on technology, online privacy and security have become vital concerns for both individuals and organizations alike. To protect sensitive data and keep online activities anonymous, Virtual Private Networks (VPNs) have become popular solutions.

In this article, well be discussing two popular VPN protocols

OpenVPN and

PPTP. Well examine what VPNs are, introduce

OpenVPN and

PPTP, and their availability on multiple platforms.

What is a VPN? A VPN is a private network that allows users to securely connect to the internet through a different server and location than their own.

This disguises the users IP address, making it difficult for external agents to track their online behavior. VPNs encrypt network traffic, making it unreadable to unauthorized parties.

Encrypted traffic provides privacy and security by protecting against hacking, data interception, and hijacking. to

OpenVPN and

PPTP

OpenVPN and

PPTP are two popular VPN protocols with their distinct features.

OpenVPN is an open-source protocol that provides high-level security using a secure SSL/TLS based encryption layer. The protocol can run on different operating systems, including Windows, macOS, Linux, iOS, and Android.

It uses the

OpenSSL library, which is respected for its strong cryptography protocols.

OpenVPN has become popular because it offers users a wide array of remote access options together with flexibility.

In contrast,

PPTP is an old and less secure VPN protocol. It is an abbreviation for Point-to-Point Tunneling Protocol, which enables VPN connections through TCP/IP.

PPTP is an outdated option, as it provides a minimal level of encryption, making it more susceptible to security breaches. Also, it is limited to a few operating systems, such as Windows, macOS, and Linux.

Availability on multiple platforms

OpenVPN has the advantage of being compatible with multiple operating systems, making it a popular VPN protocol. It supports all major desktop platforms, including Windows, MacOS, and Linux, as well as mobile platforms.

This makes it a versatile VPN protocol, making it easier for users to connect securely to the internet regardless of their device. In comparison,

PPTP is more limited; it supports fewer operating systems.

PPTP only works with devices that operate on the same platform as the VPN service providing the protocol.

OpenVPN

OpenVPN is a well-established and widely used VPN protocol. It is an open-source software with a GNU General Public License (GPL).

This means that anyone can use, modify and contribute to the development of the protocol. The software has been on the market for over 15 years and has advanced capabilities that provide users with a range of essential features.

OpenSSL library

OpenVPN is built on OpenSSL, a library that provides cryptographic protocols essential in securing network communications. OpenSSL provides protocols that ensure data integrity, authentication, and encryption – essential features in protecting the users data and privacy.

Also, OpenSSL is open-source software that undergoes constant testing and scrutiny to ensure trust and reliability.

Security

OpenVPN is a highly secure VPN protocol because of its use of OpenSSL cryptography protocols. The software uses Transport Layer

Security (TLS) to secure communications between clients and servers.

This level of security makes it almost impossible to intercept and decode user traffic. Additionally,

OpenVPN has an internal Firewall that enforces security policies to restrict access to a network or the internet.

NAT and Firewalls

OpenVPN works through NAT and bypasses firewalls. NAT (network address translation) enables a device to share a single internet connection.

OpenVPN can work through NAT because it uses User Datagram Protocol (UDP) packets instead of Transmission Control Protocol (TCP) packets. UDP allows

OpenVPN to bypass firewalls, making it almost impossible to block the VPN connection.

Compression

OpenVPN uses data compression protocols that reduce the amount of data sent over a network connection. This results in faster data transfer rates, especially with lower connection speeds, saving users both time and money in reduced data costs.

Widely used VPN implementation

OpenVPN is a widely used VPN protocol in the market, having broad community support. This has resulted in many

OpenVPN services available in the market.

Users have access to server setups with low latency and high speed to provide fast and reliable network connections. Furthermore,

OpenVPN allows for remote access to networks, enabling users to access remote servers or online services from any location.

Conclusion

In conclusion, VPNs provide increasingly essential security and privacy for internet users.

OpenVPN and

PPTP are two popular VPN protocols, with

OpenVPN generally considered more reliable and secure.

OpenVPN is an open-source VPN protocol that provides a high level of security using OpenSSL encryption. It supports multiple platforms, including mobile devices, making it easier and more versatile to use than

PPTP.

The security features in the

OpenVPN protocol protect against common security breaches such as interception, hacking, and hijacking. The compression feature in

OpenVPN also allows for faster data transfer rates, especially with lower connection speeds.

All these features make

OpenVPN a robust and reliable VPN protocol, suitable for individuals and organizations looking for secure remote access to the internet.

PPTP

PPTP is a VPN protocol that was introduced by Microsoft in the 1990s.

PPTP stands for Point-to-Point Tunneling Protocol, and it was created as a method of securely transmitting data over the internet.

It is built into mainstream operating systems, such as Windows, MacOS, and Linux, making it easier for users to deploy. Unlike

OpenVPN,

PPTP is not an open-source protocol, which means it has limited customization options.

Due to its limited security features,

PPTP is an outdated and less secure protocol. Its encryption method is MPPE (Microsoft Point-to-Point Encryption), providing minimal security that can be easily cracked by hackers.

Also, it uses MS-CHAP (Microsoft Challenge Handshake Authentication Protocol) as its authentication method, which also has known vulnerabilities that hackers exploit. Additionally,

PPTP is known to be vulnerable to attacks making it an unsecured option for accessing the internet.

Despite being an older option,

PPTP is still widely used, and it’s because it is built into most of the mainstream operating systems. It is easy to configure and set up, making it accessible to many users.

It is, however, limited in terms of its ability to bypass firewalls and work across NAT, as it uses only TCP port 1723. Differences between

OpenVPN and

PPTP

OpenVPN and

PPTP are two VPN protocols with different features and capabilities.

OpenVPN is an open-source protocol with advanced security features, while

PPTP is an outdated protocol with minimal security.

Security Implementation: MPPE and MS-CHAP vs. OpenSSL

In terms of security implementation,

OpenVPN has an advanced security feature, making it more secure than

PPTP.

OpenVPN uses OpenSSL as its encryption method instead of outdated MPPE used by

PPTP. OpenSSL is known for its high levels of security and reliability.

Additionally,

OpenVPN provides a higher level of encryption, utilizing 256-bit encryption compared to

PPTP’s 128-bit encryption.

OpenVPN also has advanced security features like perfect forward secrecy, which generates new encryption keys for each session.

In contrast,

PPTP uses MS-CHAP for authentication, which has known vulnerabilities commonly exploited by hackers. Inbuilt Support vs.

Third-party install

PPTP has an advantage over

OpenVPN in that it is built into mainstream operating systems, and its setup is less complicated since it requires minimal configurations for deployment.

OpenVPN requires third-party installation since it is not built into mainstream operating systems.
