What protocols does Surfshark VPN support and when to use them
WireGuard: fast, lean, and modern
- How it works: WireGuard is built around a minimal, efficient codebase that uses modern cryptography. It’s designed to deliver lower latency and higher throughput with a smaller attack surface than traditional VPN protocols.
- Why you’d pick it: For most daily tasks—streaming, browsing, remote work—WireGuard gives you the best speed without sacrificing security. It works well on mobile networks and unstable connections, recovering quickly when you switch networks.
- Surfshark note: WireGuard is the recommended default for speed and reliability on Surfshark’s apps. It also tends to handle smoother handoffs when you switch between Wi‑Fi and cellular data.
OpenVPN UDP/TCP: compatibility and robustness
- How it works: OpenVPN is a long-standing, highly configurable protocol that can run over UDP faster, typically preferred or TCP more reliable in networks with strict traffic shaping.
- Why you’d pick it: If you’re on a device or network where WireGuard isn’t performing well or you need broad compatibility with older routers and apps, OpenVPN is a solid choice. It’s also well-understood in corporate environments.
- Surfshark note: OpenVPN remains a dependable fallback when you encounter odd network behavior or strict firewall rules. Surfshark supports both UDP and TCP, giving you flexibility depending on your network conditions.
IKEv2: mobile efficiency and stability
- How it works: IKEv2 is known for fast reconnects and good performance on mobile devices. It’s efficient on iOS and Android, often using fewer CPU cycles than OpenVPN.
- Why you’d pick it: If you primarily use mobile devices and need quick re-connections after temporary disconnects, IKEv2 is a smart choice. It also tends to work well on networks with changing signal quality.
- Surfshark note: IKEv2 is a strong option for mobile users who want a balance of speed and battery efficiency, especially on iOS devices.
Chameleon: Surfshark’s obfuscation to beat DPI and network blocks
- How it works: Chameleon is Surfshark’s proprietary obfuscation protocol designed to hide VPN traffic patterns and emulate regular TLS/HTTPS traffic, helping evade deep packet inspection DPI and censorship.
- Why you’d pick it: In places where VPN traffic is heavily throttled or blocked such as some schools, workplaces, or countries with stringent censorship, Chameleon can help you connect more reliably.
- Surfshark note: Chameleon adds an extra layer of stealth. It’s especially useful when other protocols get detected and throttled by firewalls.
Shadowsocks: a proxy-like option for extreme restrictions
- How it works: Shadowsocks is a lightweight proxy protocol that can be used with Surfshark to bypass aggressive censorship by disguising traffic as normal web requests.
- Why you’d pick it: If you’re in an ultra-restrictive environment where VPNs are heavily blocked, Shadowsocks can be a viable alternative or complement to VPN traffic.
- Surfshark note: Shadowsocks isn’t a VPN protocol in the same sense as WireGuard/OpenVPN. it acts more like a proxy. It’s a useful tool in certain censorship scenarios but may offer different security characteristics.
How Surfshark’s protocol choices affect security and encryption
- Encryption basics: Across Surfshark’s protocols, you’ll typically see strong encryption AES-256 or ChaCha20-Poly1305 variants paired with robust handshake methods. WireGuard uses ChaCha20-Poly1305, while OpenVPN commonly uses AES-256-GCM or AES-256-CBC depending on configuration.
- Data integrity and authentication: All Surfshark protocols rely on solid cryptographic primitives to ensure data isn’t tampered with in transit. Cipher suites and handshake methods are designed to make interception or tampering impractical.
- Privacy and logging: Surfshark’s policies emphasize a no-logs approach, meaning that even if a protocol is compromised, the data available to a third party would be limited to minimal operational metadata. Always review the latest transparency reports and audits for confirmation.
Performance considerations by protocol
- Speed expectations: In independent tests and real-world usage, WireGuard generally delivers the fastest speeds among Surfshark’s options, especially on newer devices and networks. OpenVPN tends to be slower due to its larger codebase and heavier encryption/decryption, but it’s extremely reliable and widely compatible. IKEv2 often shines on mobile networks with quick reconnects. Chameleon and Shadowsocks can introduce a little more overhead but significantly improve connectivity in restricted networks.
- Latency and jitter: WireGuard’s lean protocol tends to provide lower latency and steadier throughput, which improves interactive tasks like gaming and real-time collaboration. If you’re on a congested network, Chameleon can help stabilize latency by masking traffic patterns.
- Battery life and device load: IKEv2 is typically more power-efficient on mobile devices, while WireGuard is efficient on most platforms but may consume more battery on some older devices due to continuous encryption/decryption work. OpenVPN can be heavier on older CPUs.
Step-by-step: how to switch protocols in Surfshark apps
- Desktop Windows/macOS
- Open the Surfshark app.
- Go to Settings or the top-right gear icon.
- Look for VPN Protocol or Connection Protocol.
- Choose your preferred protocol: WireGuard recommended for speed, OpenVPN UDP or TCP, IKEv2, or Chameleon for obfuscation. If you’re in a restrictive network, enable Chameleon.
- Reconnect to apply the change and test a quick speed ping.
- Mobile iOS/Android
- Tap on the gear/settings icon.
- Open Protocol or VPN Protocol.
- Select WireGuard, OpenVPN, IKEv2, or Chameleon. If you’re on a network that blocks VPNs, try Chameleon first.

- Router setup some users
- If you’re configuring Surfshark on a router, you’ll typically use OpenVPN UDP or WireGuard on compatible firmware. Check Surfshark’s router setup guides for device-specific steps and best practices.
Practical tips for choosing the right protocol
- Streaming and general browsing: WireGuard is the best default due to speed and low overhead. It handles HD streaming and video calls with less buffering.
- Gaming: WireGuard again tends to minimize latency, but if you encounter occasional disconnects on a poorly supported device, try OpenVPN UDP as a fallback.
- Highly censored environments: Start with Chameleon, and if that doesn’t suffice, try Shadowsocks in conjunction with Surfshark’s VPN for extra stealth.
- Corporate or mixed-device environments: OpenVPN is often the most widely supported protocol across enterprise-grade networks and older devices. Use UDP for speed unless the network has reliability issues that TCP would fix.
- Mobile users: IKEv2 provides fast reconnects and good battery efficiency. switch to IKEv2 if you frequently switch networks or move between Wi-Fi and cellular.
Real-world testing and data you can rely on
- Speed norms: In typical consumer testing, WireGuard on Surfshark often shows 10–35% faster download speeds and noticeably lower latency than OpenVPN on the same network, with variations by device and location.
- Reliability: OpenVPN UDP remains extremely stable across many networks, especially when a firewall or NAT traversal is involved. In some corporate or school networks, TCP might be required to avoid packet loss.
- Censorship circumvention: Chameleon and Shadowsocks significantly improve ability to connect in networks known to throttle or block VPN traffic. In such environments, these options can be the difference between a working VPN and a blocked connection.
What Surfshark’s features mean for protocol choice
- Camouflage Mode: This feature hides the fact that you’re using a VPN by masking VPN traffic as regular HTTPS. It complements protocols like OpenVPN and WireGuard in networks that enforce VPN detection.
- MultiHop: This feature routes traffic through two VPN servers in different locations. When using MultiHop, you can pair it with a protocol that balances speed and security. WireGuard or OpenVPN UDP are common first choices when enabling MultiHop for better overall performance.
- NoBorders mode: Specifically designed for environments with heavy restrictions. It works well in combination with Chameleon to maximize the chance of a successful connection.
Security, privacy, and legal considerations
