Cons of Wireguard VPN – While WireGuard may offer advantages in terms of performance and security, it’s design isn’t good for privacy.

Also, although WireGuard is still under “heavy development” and not yet ready for general use, there are lots of people who want to use it as their main VPN protocol. You can find lots of WireGuard promotions on reddit and various forums – to keep up with the latest VPN trends.

Cons of Wireguard VPN

Still under Development, and not yet just audited

WireGuard isn’t done yet. You shouldn’t rely on this code. It has not undergone a level of security audit and the protocol is subject to change. We’re working towards a stable 1.0 release, but that time hasn’t come.
However, there are several VPNs ready or offering WireGuard support right now. However, at this time you only need to use WireGuard for testing purposes only.

WireGuard logs and privacy concerns

Several VPN providers have expressed concerns about WireGuard’s ability to be used without logs, and how this may affect user privacy.

WireGuard does not have dynamic address management, client addresses are set. This means we need to register each of our client’s active devices and assign a static IP address to each of our VPN servers. In addition, we need to keep a timestamp of the last login for each device to retrieve unused IP addresses. Our users will then be unable to connect your device after a few weeks as the address will be reset.

But when it comes to WireGuard the default behavior is to have endpoints and allowed ips visible on the server interface, which doesn’t really work with our privacy policy. We must not know about your source IP and cannot accept it because it appears on our servers.

Try to get around this problem by hiring Jason Donenfeld to “write a rootkit-like module that removes the usual system administrator’s ability to query endpoints or allowed ip information about WireGuard partners and disables the ability to run tcpdump”.

New and untested

Sure, OpenVPN has its problems, but it also has a long track record and is a proven VPN protocol with extensive audits. While Donenfeld may refer to OpenVPN as “out of date” in interviews. Others may see it as proven and reliable – qualities WireGuard currently lacks.

Originally launched in 2001, OpenVPN has a very long history. OpenVPN also benefits from a large user base and active development with regular updates. In May 2017, the company underwent a major audit by OSTIF, the Open Source Technology Improvement Fund.

At the moment, WireGuard appears to be more than just a specific project – but with the potential for industry. It is very new and has not yet been out of the “heavy development” phase. Although it has gone through official confirmation. Even after WireGuard is officially released, users would be wise to proceed with caution.
