VPNs are used by many people for different purposes.
Some use them to protect their privacy.
Others use them to access geo-restricted content.
And some use them to enhance their online security.
The two most common VPN protocols used to set up a secure and private connection are OpenVPN and IPsec.
Quick Answer
OpenVPN is a more secure VPN protocol than IPsec, but it is slower. IPsec is a bit less secure but faster than OpenVPN. The performance of both protocols depends on a lot of factors, such as server location, traffic, protocol, and encryption level.
This guide will cover everything you need to know about OpenVPN vs IPsec performance, including the difference between the two and the best VPNs for both.
Overview of the Two Protocols
IPsec and OpenVPN are both well-known protocols, which are popular with users.
However, OpenVPN is the obvious choice for users looking for security, as IPsec is often only an option in situations where IPsec prevents a VPN connection.
IPsec is often also not ideal for those running server applications, as it only supports client-to-server connections, rather than client-to-client connections.
OpenVPN, meanwhile, supports both client-to-server and client-to-client connections, making it a great option for server applications.
OpenVPN also supports client-to-server connections, but is somewhat less efficient than IPsec for server applications.
IPsec and OpenVPN are both well-suited to connections that are remote and relatively slow.
These protocols are more secure than other forms of VPN, and as such, are often used for sensitive connections.
Benefits and Drawbacks of Openvpn
OpenVPN’s flexibility and support for a wide range of platforms makes it a popular choice.
- OpenVPN is open source, meaning that anyone can audit the code and suggest improvements.
- Open source also means many third-party apps and tools are available, such as scripts and libraries.
- OpenVPN supports a wide range of platforms. It supports Linux, macOS, Windows, Android, and iOS.
- OpenVPN supports a wide range of encryption protocols, including PPTP, L2TP, IKEv2, and SSTP.
- OpenVPN supports a wide range of authentication methods, including certificates, username/password, and a pre-shared key.
Benefits and Drawbacks of Ipsec
IPsec is superior in many ways to OpenVPN, making it a popular choice for VPN implementations.
IPsec is simpler to implement than OpenVPN in C and other languages, and its performance is usually superior.
It’s more secure than OpenVPN, and it’s been designed with security in mind.
IPsec is faster, though OpenVPN usually beats it in benchmarks.
IPsec is more efficient in bandwidth usage than OpenVPN, and it’s typically easier to manage.
VPN providers are more familiar with the IPsec protocol, making it simpler to implement.
Comparison of Security
Both protocols use encryption to scramble your data. OpenVPN uses a standard encryption scheme, while IPsec uses a different one.
OpenVPN uses the OpenVPN encryption protocol, which was developed based on the AES encryption algorithm. AES is a symmetric encryption algorithm and is considered “strong” by most modern standards, but it’s still not as strong as the encryption used by SSH.
IPsec uses two different encryption algorithms, the ‘Transport Mode’ and the ‘Security Association’. The Security Association encrypts the data, while the Transport Mode encrypts the data being transferred.
VPN providers usually don’t use the Transport Mode encryption, but instead the ‘Security Association’. This is because Transport Mode encryption can cause significant overhead. As a result, IPsec is considered more “secure” than OpenVPN.
If you’re only using VPN for security, then you should go with IPsec. Otherwise, you can use OpenVPN.
Comparison of Speed and Efficiency
Openvpn and IPsec are both fairly fast and secure.
OpenVPN usually performs better on speed tests, but IPsec is significantly more efficient.
IPsec uses less bandwidth and CPU resources than OpenVPN, which is beneficial for lower-end devices.
However, IPsec is significantly slower.
The speed that you experience will depend largely on your chosen server location.
It’s unlikely to find a VPN server that’s fast enough to stream Netflix HD movies, for example, and your experience will largely depend on your location.
If you use a VPN for simply protecting your privacy, speed is likely to be less important.
Key Differences Between Openvpn and Ipsec
OpenVPN and IPsec both use encryption and authentication to separate your network traffic from everyone else’s. They offer similar security.
Both protocols also support key exchange, which ensures that either side can verify that the other isn’t attempting to hijack the connection.
However, there are some key differences.
What Scenes Are Each Protocol Designed For?
OpenVPN is designed for the following use cases:
- Connectivity between devices
- Network segmentation
- VPNs for remote employees
- Connectivity between devices
- VPNs for remote employees
- Connection of enterprise networks
- Network segmentation
IPsec is designed for the following use cases:
Conclusion
VPNs are a great security tool, and their value will only increase with the growth of the Internet of Things.
Both OpenVPN and IPsec are both good options. OpenVPN has the edge in terms of speed and security, but IPsec is a lot simpler to set up and use.
If you’re just looking for a VPN to protect your privacy online, then both OpenVPN and IPsec should do the trick.
However, if you’re also looking for faster speeds, then you should opt for IPsec.
The choice is ultimately yours. However, OpenVPN offers a lot of advanced features that IPsec does not. So, if you want a VPN that offers the best of both worlds, then OpenVPN is your best option.
