Review of this VPN with WireGuard and OpenVPN

Surfshark VPN Main Features

This VPN service uses the OpenVPN protocols (either using the transport layer protocol TCP, or also UDP) and IPsec IKEv2, therefore, it uses two of the most secure VPN protocols that we can find today. The symmetric encryption used by this VPN is AES-256-GCM, therefore, we have the highest point-to-point security that currently exists. Thanks to this symmetric encryption with AEAD, not only will you protect the confidentiality of the data by encrypting it, but it will also check its integrity to ensure that the data has not been modified while traveling through the tunnel. The configuration of the VPN allows us to go to the Internet with all the traffic through the tunnel, in this way, we can hide our real public IPIn fact, not even our ISP will know that we are using a VPN.

Other features of this Surfshark service is the use of a strict no logs policy, and that is that it will not monitor, track or store what we do on the Internet through its service. They do not have no connection log no activity, which is essential to be a truly private VPN. In case of problems while we are in the VPN tunnel, the software allows us to activate the «Kill Switch«, That is, if the VPN connection is interrupted, it will block our access to the Internet so that our sensitive data is never exposed. Surfshark also offers us Private and leak-protected DNS serversThis will allow us not to use public DNS such as those of Google or our ISP, but we can use these private DNS to add an additional layer of security.

Surfshark also allows us to configure «Multi-hop«, In such a way that we connect to a certain country, and internally it redirects the traffic to another VPN server in another country, and we will go to the Internet through the latter. In other words, instead of having “one jump” to the Internet through a single server, this mode of operation allows two hops to be made, to increase security and conceal our traffic.

Uses we can give a VPN

Surfshark allows us to choose the country of connection to evade regional restrictionsOnce the country has been chosen, the software itself will take care of connecting us to the best VPN server available at a given time. As if this were not enough, we will be able set up ad and malware blockingIn this way, if we connect to the VPN, all traffic will be “cleaned” to avoid advertising, trackers, malware, and even phishing attempts. Of course, this Surfshark VPN allows us to download through the BitTorrent network without any limitation.

What devices can we connect to the Surfshark VPN? This VPN service incorporates a large number of applications for PC, smartphone and other devices. We will be able to use it in desktop operating systems such as Windows, Linux and macOS, simply installing a program that will take care of providing us with all the available options, and with which the connection to the different VPN servers is done quickly and very easily. If you don’t want to install any software on your computer, you will always be able to install extensions for Mozilla Firefox and Google Chrome browsers, ideal for browsing the Internet safely, although the traffic generated by your computer will not go through the VPN, only the web browsing with said browser.

In case you have smart TVs like FireTV or AppleTV, and even on consoles like Xbox and PlayStation, you can activate a “smart DNS” to play regionally blocked content. Finally, we have the option to configure this Surfshark VPN on our router, and is that if we have a router with VPN client compatible with OpenVPN or IPsec IKEv2 we can do it quickly. For example, if you use a router with firmware OpenWRT, DD-WRT, and even Asuswrt or Asuswrt Merlin, you can configure it so that all your home traffic travels through this VPN service.

Regarding the price of this VPN service, if you hire the 24-month option for € 42.96, It will cost us € 1.79 per month, a great discount for all the options that it offers us, and with a very good performance that you will see soon. If you decide to hire month by month the price is € 9.89, and if you contract the 12-month option for € 59.88 it will cost € 4.99 per month. An important detail is that we can try the VPN completely free for 30 days, to find out if the service it provides convinces us.

Surfshark installation and startup

As we have mentioned before, the Surfshark service is available to install as an extension in web browsers, and also on mobile devices such as Android and iOS.

Perhaps the most interesting thing about this VPN is that it also allows us to configure it directly on our router, ideal for each and every one of the devices on the local network to go to the Internet through this VPN tunnel. In case you can configure it in your router, you will not need to install any application on your computer or smartphone, since all traffic will be tunnelled thanks to the router. We can also use the official OpenVPN software itself to connect to the VPN server, without using the Surfshark software.

In RedesZone we have thoroughly tested this VPN service installing the software on a Windows 10 operating system. The installation of this program is like any program in Windows, it will only allow us to choose the destination path of said installation.

Once we have installed the software, it will ask us to log in with the credentials that we have previously created on the official website when we have registered. In the main menu we can see a button «Fast connection»To connect to the best VPN server available and the closest one geographically to us, ideal for obtaining the lowest possible latency and the highest speed. If we display the menu up, we can see our public IP and we can also enable the «Kill Switch«.

In the section of “Locations»Is where we can select the country where we want to connect to the VPN, this is ideal to evade regional blocks. We can enable the «CleanWeb»To filter ads, trackers and malware, it is disabled by default. We can also activate a whitelist so that certain programs or websites do not travel through the VPN, this will allow us, for example, to always connect to our Gmail with our Internet connection, and not using the VPN service. In the section of “MultiHop»Is where we can use two VPN hops to access the Internet, for example, we can connect to a server in the United Kingdom, and exit through the server we have in France, and all this in a totally transparent way.

As for the options of the program itself, we will be able to start it with windows, make a automatic connection as soon as you start it, activate the Kill Switch by default, notify the status, and even configure Wi-Fi networks where yes or no connect to the VPN to protect our navigation. We can also force the VPN connection to use IPsec IKEv2, OpenVPN TCP or OpenVPN UDP, although it is best to leave it on automatic so that you can select the best protocol.

As for the performance tests, our operator is MasMóvil with 600Mbps symmetric. We have made different VPN connections to different countries, to check both the latency as well as the speed that we obtain against a speed test server in that country, since otherwise we will be “going” to that country through the VPN, and “returning »Over the Internet, so the latency will be around double and the speed somewhat lower. Ideally, if you are going to browse Spanish websites, you should use the VPN server located in Spain, which is the one that will give you the best performance:

We have also tried speed tests with Surfshark in Germany, France, Portugal, Italy (Rome) and even Italy (Milan):

Finally, we wanted to check the real speed of the «Multihop», for this, we have connected to the United Kingdom -> France server, to go to the Internet through our neighboring country. Throughput is around 40Mbps download and 25Mbps upload, with a latency of 75ms, which is an excellent result considering the “two hops”.

This Surfshark VPN not only incorporates a large number of additional services, but it will also allow us to configure our router with OpenVPN or IPsec client very easily, therefore, it is not necessary to use its software for the different platforms that we have available. A very important point in favor is the low latency of the connection, and also the real download and upload speed that it is capable of providing, since we must remember that all traffic is encrypted and authenticated.

This VPN service is one of the best we have tested to date, and also one of the most versatile, with very high security thanks to the use of OpenVPN and IPsec IKEv2 using AES-256-GCM, and also having available the Kill Switch.

Surfshark incorporates the WireGuard VPN protocol

This popular VPN service has incorporated the new WireGuard protocol, a very new, fast and totally secure VPN protocol that is already integrated into the Linux Kernel. All current operating systems are compatible with WireGuard, in addition, Surfshark already has applications specifically designed for all of them with this new addition. The most remarkable thing about WireGuard is that it is a very light protocol with maximum security by default, in addition, thanks to its efficiency we will be able to achieve greater speed compared to OpenVPN or IKEv2 that we have talked about previously.

WireGuard uses the following security by default:

  • ChaCha20 for symmetric encryption, and Poly1305 for authenticated data, it is AEAD.
  • Curve25519 for ECDH.
  • BLAKE2s for hashing.
  • SipHash24 for the key hashes table
  • HKDF for key derivation

Other positive aspects of this new WireGuard protocol that is incorporated in Surfshark, is that the connection is made very fast, much more than OpenVPN or IPsec, and this you can verify perfectly. We have tested the latest version of Surfshark 2.7.4 software for Windows, which already incorporates this new WireGuard. Furthermore, if we select the “automatic” mode, it will always give priority to this protocol. Of course, we can choose the protocol in a specific way, to always use it and not use OpenVPN or IPsec.

Regarding the difference in performance between WireGuard and OpenVPN, in RedesZone we have carried out some tests and we have obtained these speeds:

  • WireGuard: 460Mbps download and 390Mbps upload.
  • OpenVPN with UDP: 90Mbps download and 90Mbps upload.
