What is the WireGuard protocol 

WireGuard is a new open-source VPN protocol that uses state-of-the-art cryptography and aims to be simpler, faster, and more secure than the existing VPN protocols. It is considered to be better designed than the IPSec protocol and to provide better performance than OpenVPN. 

Developed by Jason Donenfeld and introduced in 2018, WireGuard was quickly accepted by users worldwide. It even caught the attention of Linux Torvalds, the developer behind Linux, who called it a work or art: 

Can I just once again state my love for it (WireGuard) and hope it gets merged soon? Maybe the code isn’t perfect, but I’ve skimmed it, and compared to the horrors that are OpenVPN and IPSec, it’s a work of art. 

What’s so special about WireGuard? Well, it does have some advantages over the existing VPN protocols. 

Why use WireGuard VPN protocol: main advantages 

Updated encryption technology 

Jason Donenfeld intended to upgrade what he considered to be the outdated aspects of OpenVPN and IPSec protocols. This said, WireGuard eschews standard algorithms that have long-lasting weaknesses in favor of the most modern, strongest cryptographic primitives (low-level algorithms). As stated on the WireGuard website, the following ciphers are used:

  • ChaCha20 for symmetric encryption, using Poly1305 for authentication
  • Curve25519 for ECDH (Elliptic-curve Diffie-Hellman, a key agreement protocol for establishing a shared secret over an insecure channel)
  • SipHash24 for hashable keys
  • BLAKE2s for hashing and keyed hashing
  • HKDF for key derivation

Simple code base

The WireGuard protocol features much lighter build than most VPN protocols (at least open-source ones, with visible codes). All in all, WireGuard weighs around 4000 lines of code, which is in stark contrast to 600 000 total lines of OpenVPN and OpenSSL combined. IPSec is also quite bulky, featuring 400 000 lines with XFRM and StrongSwan together. 

WireGuard VPN protocol's code is significantly more simple than its counterparts'

What’s the benefit? Actually, there are several advantages:

  1. Fewer lines of code imply much less attack surface in comparison to OpenVPN and IPSec. 
  2. Smaller code base is much easier to audit. OpenVPN would require a team of auditors who’d be checking it for days, while one person can audit WireGuard’s code in just a few hours. 
  3. Easier audit means it’s easier to find vulnerabilities and keep the protocol secure. 
  4. Less bulky code also means it is more likely to work as it’s supposed to. 

Better performance

High-speed cryptographic primitives and peculiarities of WireGuard technology potentially bring significant performance improvements, both on small devices like smartphones and loaded backbone routers. 

WireGuard’s small code base allows it to offer users quite decent speeds. It should allegedly be capable of establishing connections and handshakes faster, at the same time offering enhanced reliability. Mobile users should especially benefit from WireGuard as it is designed to be less resource-consuming and not eat up too much battery.      

All in all, WireGuard protocol should outperform other protocols in terms of:

  • Speed
  • Reliability
  • Longer battery life on smartphones and tablets
  • Faster connection and reconnection 

Cross-platform use 

Though originally released for Linux-based operating systems, WireGuard can now be adapted for a number of different platforms. For example, it may be used on systems running macOS, Ubuntu, iOS, and Android, thus covering a wide range of devices.

How to start using WireGuard protocol 

Currently, there aren’t many WireGuard VPN providers. However, KeepSolid VPN Unlimited offers you an opportunity to try out this most modern VPN protocol yourself. All you need to do is follow a few simple steps below:  

  1. Download KeepSolid VPN Unlimited app.
  2. Create your KeepSolid ID or log in.
  3. Navigate to the app Menu > Settings.
  4. Go to Protocols and select WireGuard.

  5. Start exploring the next-gen protocol! 

Note: Currently, we’ve implemented WireGuard protocol in the macOS and Android versions of KeepSolid VPN Unlimited app. Though already available for Personal Server and Personal IP users, WireGuard on Windows and iOS for all VPN servers is coming soon, stay tuned! 

Bottom line on WireGuard VPN protocol

Providing high-speed connection and unmatched security at the same time is a constant challenge for VPN services. However, the innovative WireGuard solution brings radical change in the industry, featuring simple build, fast connection speed, and strong cryptography.  

Dive into the new enhanced VPN experience with KeepSolid VPN Unlimited and WireGuard, the VPN protocol of the future!  


  1. I have found KeepSolid VPN Server addresses to be VERY Limited in Australia.

    KeepSolid used to offer Servers in 2 cities MELBOURNE SERVER but stopped it and now you only offer SYDNEY area SERVERS.

    Personally, it would be more useful to have a Brisbane or South-East QUEENSLAND VPN Server!


    Because DAYLiGHT SAViNGs TiME (aka Summer Time) is only in those Southern States, and the server time differences has COST me DEARLY for a few online purchases, as well as iNTERNET BANKING hassles I have experienced.

    The ABC (abc.net.au) Radio and TV networks offers an iView service which is Very similar to the BBC UK iPlayer service and then there is the Multi-Cultural SBS.com.au also offers a similar service, so separate servers for both of those networks would also be useful.

    VPN_Unlimited has come a long way since I signed up over 5 years ago, however in some aspects Keepsolid has become more limited.

    1 final gripe: An Animated Tray iCON (flashing Red on Yellow) Tray icon would also be of great assistance when the VPN has dropped out, BECAUSE Nobody I know of or I’ve talked too, has noticed the pale grey icon when the connection drops out

    Well that’s all I have to say, and thanks for listening, but, I won’t hold my breath waiting for any of the changes I’ve suggested/requested.

    • Hi,

      Thanks for sharing your feedback! We’re always expanding our servers list and let our users vote for the most desired locations on this page. Just scroll down to the section shown below, type in or select the country, and press Send.
      Voting for new VPN servers

      We’ve added all the mentioned servers, as well as an animated tray icon to our wish list, so our team can consider their implementation in future.

      Speaking about a brighter tray icon, it may be a good idea, but it can’t save you from a data leak during sudden connection drops. For such cases, there’s a much better solution – the Kill Switch feature that protects your data whenever VPN accidentally drops out. Find more information about it here. Do try it out 😉

      Also, would you mind providing more details about any limiting aspects? We constantly strive to make our service better for our users and are always grateful for any feedback, so will be waiting yours 🙂

  2. Great news. When will you introduce a DNS level adblocker on the server side? I’ve been a lifetime subscriber for 5 years and that’s the only thing missing from your excellent app.

    • Hey there,

      Cool to hear from you & thanks for choosing us! We’re already working on the feature that will include DNS-level ad-blocker. So you’ll be able to enjoy the new perfect version of VPN Unlimited soon 😊

      It’s coming in 2020, but we cannot announce ETA as of now. Stay tuned!


    • Hi John,

      To date, we can’t provide you with approximate dates of the implementation of new servers or locations in our security solution. Now we are gathering feedback on the most desired locations, so thank you for voting for South America 😉
      Stay tuned to our updates!
