Is Surfshark’s WireGuard Protocol as Secure as OpenVPN?


WireGuard is claimed to be way better and more secure than OpenVPN. Surfshark has finally adopted this latest security protocol and is offering it on Windows, Mac, Android, and iOS devices to improve its speed further and ensure users’ security.

To learn more about what this affordable VPN offers, just go through our Surfshark review.

Surfshark is one top-notch VPN to use that offers highly encrypted security features, a reliable connection, and affordable prices to users. Previously, Surfshark was widely offering OpenVPN as one of its VPN protocols. While OpenVPN is still being offered, WireGuard has also been added to the list to compete against the VPN protocols.

To further compare OpenVPN with the relatively new VPN protocol WireGuard, let’s read what WireGuard is.

What is the WireGuard protocol?

WireGuard is one current VPN protocol that got quickly adopted by almost all top VPN providers due to the perks it offers. This tunneling protocol was designed to provide better VPN speeds and a much easier and safer connection to users. It initially launched for the Linux Kernel and then got adopted widely by macOS, Android, iOS, and Windows.

We all know that the best VPN services use specific encryption protocols to ensure their users’ privacy and security. These VPN protocols create an encrypted tunnel to mask complete user activity over the internet from their Internet Service Providers (ISP) and the government. WireGuard does the same, but more efficiently.

Is WireGuard more secure than OpenVPN?

WireGuard is known to be better than all previous VPN protocols offered, including OpenVPN. We can judge this because WireGuard contains 4,000 coded lines compared to the 400,000 lined codes of OpenVPN. Let’s check out some factors to compare WireGuard with OpenVPN:

1. Speed:

WireGuard is claimed to offer faster VPN speeds to users. Many users have switched to WireGuard from OpenVPN protocols on their Surfshark VPN app after this claim. We confirmed this too by conducting a speed test. Remember that not every VPN offers WireGuard protocol yet. You need Surfshark or any other premium VPN for this.

2. Security:

Both these VPN protocols are pretty secure and ensure that a user’s activity is entirely encrypted. But, WireGuard is a step ahead. WireGuard has a much newer and state-of-the-art algorithm that makes it superior to OpenVPN. Hails to its smaller code, auditing for hacks has become relatively easier too. It also tends to protect users from specific dangerous attacks.

3. Encryption:

WireGuard tends to use some modern and latest protocols to encrypt user data. Let’s check out some algorithms that both these protocols:

WireGuard’s algorithms: ChaCha20, Blake2s, UDP, Poly1305, etc.

OpenVPN’s algorithms: Blowfish, Camellia, ChaCha20, MD5, MD4, SHA-1, UDP or TCP, etc.

4. Auditability:

As we previously mentioned, WireGuard has a shorter code than OpenVPN and is much easier to conduct security audits on than OpenVPN’s 400,000 lined code. This is enough to prove that WireGuard is much easier to audit than OpenVPN.

After this detailed comparison, I think we all agree that WireGuard’s claims are entirely justified, and it is, in fact, a better tunneling protocol than all other Surfshark protocols.

What are some disadvantages of WireGuard?

Here are some shortcomings at this WireGuard’s end that need to be taken into account:

1. While Virtual Private Networks (VPNs) claim and believe in complete user privacy, WireGuard doesn’t take it too seriously. WireGuard saves all user IP addresses on the VPN servers until the servers are not rebooted. This situation is ironic because while VPNs offer a complete no-logs policy, this protocol goes against it.

2. WireGuard also does not offer dynamic IP addresses to users. This is yet another drawback of this protocol that goes against VPN providers.

What other protocols are offered by Surfshark?

Surfshark VPN offers three other protocols than WireGuard that users can connect to. These include:

  • IKEv2
  • OpenVPN
  • Shadowsocks

IKEv2: This is one of the oldest and most popular protocols used by the Surfshark VPN. With its amazing features, security, and hassle-free usage, most VPNs commonly offer this protocol and are used by many users.

OpenVPN: This is one open-source protocol that remained popular until the entry of WireGuard. This protocol is constantly under the development stage and keeps getting improved by professionals. It’s called open-source for a reason.

Shadowsocks: This especially works for countries that have severe internet restrictions like China. If you don’t live in any of those regions, you’re better off using the above-listed protocols instead of Shadowsocks.

Yes, WireGuard is a safe, secure, and fast protocol. Unlike OpenVPN which operates 100,000 lines of code, WireGuard uses 4,000 lines, making it more efficient.

Surfshark offers three tunneling protocols:

  • Wireguard is the best and latest protocol offering fast speeds.
  • IKEv2 is also a fast protocol, good for mobile devices.
  • OpenVPN is the most secure VPN protocol.

Surfshark’s Wireguard protocol is a more reliable connection as compared to OpenVPN because it can handle network changes better, especially on mobile phones. WireGuard only uses 4% more data while OpenVPN uses about 20% of data.


Surfshark is one top VPN providers to subscribe to if you’re looking to connect to the WireGuard protocol. Despite some drawbacks, you cannot deny that this protocol offers excellent speed and security to users. You can torrent using Surfshark’s P2P optimized servers or unblock Netflix with Surfshark using these speeds. And who knows? WireGuard may come up with some further developments with time, remove these lags, take user privacy more into concern while offering users the best encryption protocol possible.

If you are skeptical about Surfshark performances or you didn’t like its services after trying, you still have the option to cancel Surfshark subscription and claim for a refund. Surfshark also offers a free trial for 7 days on mobile devices.  You can also contact 24/7 live support for gathering further information.
