Different protocols have different ways of doing this, which affects your connection’s speed, security, and stability. It’s essentially the engine of your VPN, and Surfshark offers a few top-notch engines to choose from. How well a protocol performs often depends on how well the VPN provider has built out its infrastructure, and Surfshark’s network of over 3,200 servers in 100 countries, many with 10Gbps ports, is designed to make these protocols sing.

Surfshark’s Core VPN Protocols: Your Choices Explained

Surfshark primarily offers three highly respected VPN protocols: WireGuard, OpenVPN, and IKEv2/IPsec. Each one has its own special sauce, making it better for certain situations. Let’s break them down.

What is Surfshark VPN and Why Does it Matter?

WireGuard: The Speed Demon

If you’re all about speed and efficiency, WireGuard is probably going to be your go-to. It’s the new kid on the block, relatively speaking, but it has quickly become an industry favorite for good reason.

• Why it’s awesome: WireGuard boasts a super lightweight codebase, with only about 4,000 lines of code. Why does that matter? Less code means it’s easier to audit for security flaws and less susceptible to vulnerabilities. More importantly, this lean design translates directly into blazing-fast speeds and impressive performance without cutting corners on security. It’s built on modern cryptographic principles, making it very secure while keeping things simple and efficient.
• Performance data: Surfshark has really optimized its WireGuard implementation. Recent speed tests, including those by TechRadar, have shown Surfshark clocking in at over 950 Mbps using WireGuard, sometimes even maxing out connection lines. In other tests, Surfshark with WireGuard retained about 81% of download speed, which is fantastic for a VPN. This means you can count on it for demanding activities like streaming in 4K, competitive online gaming, and quick torrenting of large files without noticeable lag.
• Best for: Most users, especially if you prioritize speed for streaming, gaming, torrenting, or just everyday browsing where you don’t want any slowdowns. It’s generally considered the fastest VPN protocol on Surfshark and an excellent all-around choice. Surfshark has even started implementing post-quantum encryption algorithms on top of WireGuard for future-proofing.

OpenVPN: The Reliable Workhorse

OpenVPN is the tried-and-true classic of VPN protocols. It’s been around for a while, it’s open-source, and that means security experts worldwide have scrutinized its code countless times, making it incredibly trustworthy.

• Why it’s awesome: OpenVPN is known for its robust security features and strong encryption capabilities. It offers a fantastic balance between security and performance, making it a very versatile choice. You’ll often find two flavors:
  • OpenVPN UDP: This version is generally faster and great for things like streaming, video calls, or online gaming where speed is a bit more critical, but a dropped packet isn’t the end of the world.
  • OpenVPN TCP: This one is all about stability. It ensures that every single data packet is delivered, making it more reliable for sensitive tasks where data integrity is paramount, even if it might be a bit slower than UDP.
• Performance data: While not as blisteringly fast as WireGuard, OpenVPN UDP still delivers solid speeds. One test showed OpenVPN UDP with about 62% download speed retention, which is quite good. OpenVPN TCP is generally slower due to its retransmission mechanisms, with one test showing about 7% download speed retention, so it’s best reserved for situations where maximum stability is needed over speed.
• Best for: When security and reliability are your top priorities, or when you’re connecting your VPN to a router, as many routers natively support OpenVPN. It’s also often used in Surfshark’s Camouflage Mode obfuscation which we’ll talk about later, helping you get around strict network restrictions.

IKEv2/IPsec: The Mobile Champion

IKEv2/IPsec Internet Key Exchange version 2 combined with Internet Protocol Security is another fast and secure protocol that’s particularly popular with mobile users.

• Why it’s awesome: The big strength of IKEv2 is its stability and ability to handle network changes seamlessly. If you’re someone who often switches between Wi-Fi and mobile data on your phone or tablet, IKEv2 is excellent because it can quickly re-establish your VPN connection without dropping. It’s also known for its strong security and speed. Surfshark often sets IKEv2 as the default protocol on iOS devices for this very reason.
• Performance data: IKEv2 is very efficient and offers speeds comparable to WireGuard in many scenarios, making it a strong contender for mobile performance. It’s generally considered one of the fastest protocols available today, alongside WireGuard.
• Best for: Mobile devices smartphones, tablets where you need a stable connection that can quickly reconnect as you move between different networks. It’s fantastic for users who are frequently on the go.

How to Choose the Best Surfshark VPN Protocol for You

Choosing the “best” protocol isn’t a one-size-fits-all answer. It really comes down to what you’re doing online and what your priorities are. Surfshark lets you easily switch protocols within the app’s settings, so you can always adjust.

Prioritizing Speed vs. Security vs. Stability

• For Maximum Speed: If you’re all about streaming high-definition content, engaging in online gaming, or downloading large files, WireGuard is almost always your best bet. It’s designed for efficiency and consistently delivers the fastest speeds.
• For Rock-Solid Security & Reliability: When privacy and data integrity are paramount – think online banking or handling sensitive work documents – OpenVPN TCP offers that extra layer of stability ensuring every packet is delivered, though it might be a bit slower. OpenVPN UDP still provides strong security with better speeds for general secure browsing.
• For Mobile On-the-Go Stability: If you’re frequently moving and switching between Wi-Fi networks and mobile data, IKEv2/IPsec is fantastic. Its ability to quickly reconnect makes it ideal for maintaining a consistent VPN connection without interruptions. WireGuard also performs exceptionally well in this regard, sometimes even better as it doesn’t lose connection when changing networks in the first place.

Specific Use Cases

• Streaming: For unblocking geo-restricted content and enjoying buffer-free streaming on platforms like Netflix, Hulu, or BBC iPlayer, WireGuard is the clear winner due to its speed. Surfshark is excellent for streaming, consistently unblocking various platforms.
• Gaming: Low latency is key for gaming. Again, WireGuard typically offers the best performance here, ensuring your game doesn’t lag.
• Torrenting: For fast and secure file sharing, WireGuard provides excellent speeds. All Surfshark servers are P2P-friendly, so you can torrent on any server with confidence.
• Browsing & General Privacy: For everyday web browsing, protecting your privacy, and staying secure on public Wi-Fi, WireGuard offers a great balance of speed and security. OpenVPN UDP is also a solid choice.
• In Restrictive Countries e.g., China: In regions with heavy internet censorship, you might need special features. Surfshark’s Camouflage Mode which runs automatically with OpenVPN UDP or TCP and NoBorders Mode are specifically designed to bypass these restrictions by making your VPN traffic look like regular internet traffic.

How to Change Protocols in Surfshark

Changing your VPN protocol in the Surfshark app is super easy.

1. Open the Surfshark app and go to Settings.
2. Navigate to the VPN Settings section.
3. Find and tap on the Protocol tab.
4. Select your preferred protocol from the list.

It’s that simple! Surfshark’s app is generally very user-friendly, displaying your active settings, including the protocol, kill switch status, and more.

Understanding Surfshark’s Other Security Layers

Surfshark doesn’t just rely on strong protocols. it packs a punch with a suite of additional security and privacy features that work together to keep you safe.

NoBorders Mode

This feature is a lifesaver if you find yourself in a region with heavy internet restrictions or censorship, like some parts of the Middle East, or if you encounter strict network firewalls like at school or work. When the Surfshark app detects these kinds of network limitations, NoBorders Mode automatically kicks in, giving you access to a special list of servers that are optimized to bypass these blocks. It essentially ensures you can still enjoy an open internet experience even when others are trying to limit it.

Camouflage Mode Obfuscation

Ever worried that your Internet Service Provider ISP might know you’re using a VPN, even if they can’t see your activity? That’s where Camouflage Mode comes in. Also known as obfuscation technology, this feature disguises your VPN traffic, making it look like regular internet traffic. This is super important because some ISPs use Deep Packet Inspection DPI to detect and block VPN connections. Camouflage Mode helps you fly under the radar, ensuring that even your ISP can’t tell you’re using a VPN, adding another layer of privacy. It runs automatically when you use the OpenVPN UDP or TCP protocols.

Kill Switch

Imagine your VPN connection suddenly drops for a split second. Without a Kill Switch, your real IP address and online activity could be exposed, even if just for a moment. Surfshark’s Kill Switch feature acts as a safety net, automatically disconnecting your device from the internet if your VPN connection ever drops. This prevents any accidental data leaks, ensuring your online activities remain private and secure at all times. It’s a crucial feature for anyone serious about privacy.

CleanWeb

Nobody likes ads, trackers, or malware, right? CleanWeb is Surfshark’s built-in solution to combat these nuisances. It blocks ads, trackers, and malicious websites at the DNS level, leading to a faster, cleaner, and safer browsing experience. By filtering out unwanted content, it not only protects you from potential threats but also helps improve your browsing speed and saves bandwidth.

No-Logs Policy

One of the cornerstones of a trustworthy VPN is a strict no-logs policy, and Surfshark takes this very seriously. A no-logs VPN means the provider doesn’t track, collect, or store any information about what you do online – no browsing history, no IP addresses, no connection timestamps, no used bandwidth, nothing. Surfshark operates under a strict no-logs policy, which has been independently audited by Deloitte, one of the “Big Four” auditing firms, not once, but twice in 2023 and again in 2025. This independent verification confirms that Surfshark adheres to the highest privacy standards, giving you peace of mind that your online activities are truly your business. They even use RAM-only servers, which means all data is wiped with every reboot, adding an extra layer of privacy.

Dynamic MultiHop Double VPN

For those who want an extra layer of anonymity and security, Dynamic MultiHop also known as Double VPN is a great feature. Instead of routing your internet traffic through just one VPN server, MultiHop sends it through two different VPN servers in different countries. This adds an additional layer of encryption and makes it even harder to trace your online activities back to you. Surfshark allows you to manually choose your entry and exit server locations, offering great flexibility.

Bypasser Split Tunneling

Bypasser, Surfshark’s version of split tunneling, allows you to choose which apps or websites use the VPN connection and which bypass it and connect directly to the internet. For example, you might want your torrent client to always use the VPN for privacy, but your online banking app to connect directly for security reasons some banking apps can be finicky with VPNs. This feature is quite impressive, as Surfshark is one of the few VPNs to offer split tunneling on iOS and macOS, which can be tricky due to Apple’s system changes.

How Fast is Surfshark VPN? Unpacking Its Speed and Performance

Is Surfshark VPN Fast?

This is a question many people ask, and the answer is a resounding yes, Surfshark VPN is fast. Speed is a huge factor when choosing a VPN, as nobody wants their internet slowed down to a crawl. While any VPN will introduce some speed loss due to encryption and routing traffic through a server, Surfshark minimizes this impact beautifully.

• Impressive Performance: Recent tests in 2025 consistently rank Surfshark among the fastest VPN services available. TechRadar, for instance, recorded speeds of over 950 Mbps using the WireGuard protocol, often maxing out the test connection line. This puts Surfshark at the top of overall speed rankings.
• Low Speed Loss: When connecting to nearby servers, users often experience minimal speed reduction, sometimes as low as a 4-5% drop in download speeds. Even for long-distance connections like US to Singapore, average speed loss was around 14%, which is still very competitive.
• Optimized Network: Surfshark’s speeds are bolstered by a continually optimized server network, featuring over 3,200 10Gbps servers in 100 countries. They also cap server loads at 40% capacity, helping to prevent congestion and maintain high speeds for all users.
• Consistent Across Protocols and Platforms: Whether you’re on Windows, macOS, iOS, or Android, and regardless of the protocol you choose especially WireGuard, Surfshark delivers consistent speed performance. For example, tests showed a 17% speed loss on macOS with WireGuard from a 370 Mbps base connection, 23% on Windows with WireGuard, and similar consistent results with OpenVPN.

So, if you’re looking for a VPN that won’t slow you down for streaming, gaming, video calls, or heavy browsing, Surfshark is definitely up to the task.

What Does Surfshark VPN Do?

Essentially, Surfshark VPN creates a secure, encrypted tunnel between your device and the internet. When your internet traffic passes through this tunnel, your data is encrypted, and your real IP address is replaced with the IP address of the VPN server you’re connected to. This makes it incredibly difficult for anyone – your ISP, government agencies, hackers, or advertisers – to snoop on your online activities, track your location, or link your browsing to your identity.

Beyond basic privacy and security, Surfshark helps you:

• Access Geo-Restricted Content: By changing your virtual location, you can access streaming services and websites that might not be available in your physical region.
• Bypass Censorship: Features like NoBorders Mode and Camouflage Mode allow you to circumvent internet restrictions and censorship in various countries.
• Protect Against Cyber Threats: With AES-256-GCM encryption, CleanWeb, and a Kill Switch, Surfshark shields you from malware, trackers, and data leaks.
• Secure Public Wi-Fi: Public Wi-Fi networks are often unsecured. Surfshark encrypts your data, protecting you from malicious actors on these networks.
• Maintain Anonymity: Your activities aren’t logged, your IP can be rotated, and MultiHop offers double encryption, making it incredibly hard to trace your online footprint.
• Enjoy Unlimited Devices: One Surfshark subscription allows you to connect an unlimited number of devices simultaneously, which is a huge benefit for households or small businesses.

Is Surfshark VPN Safe to Use?

Absolutely. Surfshark has built a strong reputation for security and privacy. Here’s why:

• Strong Encryption: Surfshark uses industry-leading AES-256-GCM encryption, which is considered virtually unbreakable by modern supercomputers. This is the same level of encryption used by banks and militaries. They also implement Perfect Forward Secrecy PFS, which ensures unique encryption keys for each session, further enhancing security.
• Audited No-Logs Policy: As mentioned, Surfshark has a strict no-logs policy, meaning they don’t collect any sensitive user data. This policy has been independently verified by Deloitte multiple times, providing solid proof of their commitment to user privacy.
• RAM-Only Servers: All of Surfshark’s servers are RAM-only, meaning they run entirely on volatile memory. When a server reboots, all data is wiped, eliminating any possibility of long-term data storage.
• Advanced Security Features: The suite of features like Kill Switch, CleanWeb, Camouflage Mode, and Private DNS on every server significantly boosts your overall security posture.
• Jurisdiction: Surfshark’s headquarters are in the Netherlands after merging with Nord Security, but it operates under a strict no-logs policy, verified by audits, which is more important than jurisdiction alone. Furthermore, Surfshark is a founding member of the VPN Trust Initiative, promoting transparency and security standards in the VPN industry.

Surfshark VPN Proxy: What’s the Difference?

You might have seen the term “Surfshark VPN proxy” floating around, especially in related keyword searches. It’s important to understand the distinction between a VPN and a proxy.

• Proxy: A proxy server acts as an intermediary between your device and the internet. It can change your IP address, allowing you to bypass some geo-restrictions, but it typically does not encrypt your internet traffic. This means your data is still visible to your ISP and potentially other third parties, making it less secure than a VPN. Proxies are generally faster because they lack encryption overhead. Surfshark does offer browser extensions that function as secure proxy servers, but they only protect browser traffic, not your entire device.
• VPN: A VPN, like Surfshark VPN, does everything a proxy does changes your IP, bypasses restrictions but crucially encrypts all your internet traffic. This provides a much higher level of security and privacy because your data is scrambled and unreadable to snoopers. When you connect to Surfshark, all your device’s traffic apps, browser, etc. goes through the encrypted tunnel.

While Surfshark’s browser extensions provide a proxy function, when people talk about the core “Surfshark VPN,” they’re referring to the full VPN service that encrypts all your traffic. For maximum security and privacy, a full VPN connection is always recommended over just a proxy.

Tips for Optimizing Your Surfshark Connection

To make sure you’re getting the best possible experience from Surfshark, here are a few quick tips:
