In today’s world most of us if not all of us have heard of the term VPN! There are so many different types of VPN out there which can make it a little overwhelming when deciding which one is right for your particular needs. It is so important to make the right choice for you!

WireGuard! Have you heard of it? It’s a new VPN technology that has been described as perhaps the simplest and most secure VPN out there!


It’s a modern VPN that is very easy to understand. It aims to be much faster, simpler, and leaner than its rival IPSEC! Also, the way it has been designed makes it deliver much more performance than an open VPN.

In contrast to an open VPN, it uses a reduced number of state-of-the-art cryptographic methods. It is designed as a universal VPN for operation on embedded supercomputers and devices.


There are pros and cons to all VPNs and despite it being declared incomplete and unstable, WireGuard is already being promoted by its developers as the most secure and simplest VPN technology on the market today! It seems to be very popular with application developers.


VPNs are indispensable to businesses. They link remote office branches to the corporate main network, which then allows roaming employees to use the internal company applications and enables cloud servers to be part of the same network as the on-premises ones.

We are always on the lookout for ways how to improve our online security. Being safe is crucial to insure all of your personal data is safe from hackers and third parties who wish to access your information.

Quite frankly we are too irresponsible when it comes to protecting ourselves online. We seem to take action only after someone has stolen our information. Save yourself all of the unwanted stress and insure you have the right VPN for your needs.

WireGuard uses proven cryptography protocols and algorithms to protect your data! Even though it was originally compatible with the Linux kernel it is now available for Mac, Windows, iOS, and Android.


The reason for it achieving much faster speeds is because it has a lean structure. When comparing it to other protocols it’s only fair to compare it with something that also runs in the Linux kernel.

WireGuard also doesn’t respond to any packets from peers that it doesn’t recognize. Meaning the network scan will not reveal that WireGuard is running on a machine! Like any other VPN, it’s responsible for creating a secure connection between a VPN app and a VPN server.

Basically, it exchanges public keys. Once they are exchanged and the app server tunnel is established, there’s no need to keep managing the connection. Once it establishes the VPN tunnel, the server must receive at least one encrypted data packet from the client before it can use the session, this insures proper key confirmation.


There was once a huge concern that VPN providers who use WireGuard wouldn’t be able to offer complete privacy because it stores users' IP addresses on the server until restarts it. However, providers quickly solved this particular issue by either using a double NAT system or erasing the IP logs once the session ended.

Theoretically, WireGuard should offer proven performance in the way of the following:

  • 1. Greater speeds

  • 2. Increased battery life with phones and other mobile devices

  • 3. Improved roaming support for phones and other mobile devices

  • 4. More reliability

  • 5. Much quicker at establishing connections.


Mobile VPN users in particular will find WireGuard to be particularly beneficial. If your mobile device switches from WiFi to mobile data, the connection will not be interrupted. It will remain as long as the VPN client continues to send authenticated data to the VPN server.


Unfortunately, there are various privacy concerns when it comes to WireGuard. By default, it saves connected IP addresses to the server. These user IP addresses are saved on the server indefinitely, or until it’s rebooted.

Energy efficiency is of course important for mobile devices and WireGuard is well positioned for such applications. For example, the protocol supports roaming i.e the automatic switch over from WLAN to the mobile network and vice versa. If the connection is somehow lost then it is usually quicker to reconnect with WireGuard than with any other rival protocol.


If you are planning to use WireGuard, you should be aware that it is an unfinished program, and somewhat underdeveloped. Of course, it has many advantages but it’s important to know the disadvantages also.

  • 1. The software still remains in the development phase.

  • 2. No server verification

  • 3. Proxy connection and authentication are not possible

  • 4. Doesn’t support TCP (at the moment)

Although it is already usable, the developers haven't finished a stable version yet. Even they state that the code isn't trusty at this time. The software still has to go through various IT security audits in which security experts will check the code quality. It is a necessity to take special care as code errors and security holes would have serious implications!

I’m sure with some time when it’s fully developed the advantages will outweigh the disadvantages. Until then the more sensible option would be to go with a VPN that provides you with 100% security! Of course, it is reliable in certain areas. However, you should still avoid any underdeveloped VPN until it can provide guaranteed safety.

In conclusion, no one wants their private information accessible to anyone and everyone! WireGuard is just way too underdeveloped and anyone who chooses to use it (in my opinion) is taking a huge risk! Although it has its good points it’s still not at the stage where it can fully protect you, there are just too many risks. There are so so many other options available for your online privacy, Stay safe and protected make the right choice for you! When it’s fully developed I have no doubt it will be amazing!
