VPN mit WireGuard: Neun Anbieter im Vergleich (2024)

FAQs

Is the WireGuard VPN any good? ›

Is WireGuard secure? WireGuard is considered by many to be one of the safest, most secure VPN protocol options available today. Simplified design using less code equals fewer bugs and security vulnerabilities, while WireGuard's faster state-of-the-art cryptography employs superior default security settings.

WireGuard first gained traction several years ago and has since become one of the principal standards for any VPN worth its salt. Many VPNs have moved from OpenVPN to WireGuard since its release because it combines security, speed, and ease of implementation into a single package, and their services are better for it.

To check if WireGuard Server is working properly

The simpliest way is to use a cell phone with WireGuard official client app installed, turn off its Wi-Fi connection, and only connect to Internet via 3G/4G/5G.

One of the key advantages of WireGuard is its minimal attack surface. The protocol's codebase is remarkably small, consisting of only a few thousand lines of code. This lean design reduces the potential for vulnerabilities and makes it easier to audit and maintain the codebase.

Tailscale does more than WireGuard, so that will always be true. We aim to minimize that gap, and Tailscale generally offers good bandwidth and excellent latency, particularly compared to non-WireGuard VPNs.

Yes. WireGuard is designed with a strong focus on security, leveraging state-of-the-art cryptography to provide high-end protection for data in transit. Its choice of modern cryptographic primitives provides a robust foundation against various attacks.

Cost and Licensing

Since WireGuard and OpenVPN are free software, there is no expense associated with using them. Though there are some free solutions, you'll still need to pay for a VPN subscription. Since WireGuard and OpenVPN are free software, there is no expense associated with using them.

When you connect to our VPN server via WireGuard, your device can only see the IP address 10.2. 0.2, and the website you visit can only see the public IP address of our VPN server. Your true IP address remains secure and private, just as it would with OpenVPN.

NordLynx is NordVPN's revolutionary technology built around the WireGuard® VPN protocol. It helps you connect to NordVPN servers faster and improves your VPN connection speeds without compromising security or privacy.

WireGuard does not provide obfuscation, meaning that internet service providers (ISPs) can see when you are using it — although, of course, they can't see what you're using it for. This means that a WireGuard VPN won't necessarily be able to help you bypass firewalls.

How do I know if my VPN is working properly? ›

How do I check if a VPN is working? Visit websites such as WhatIsMyIP or IPLocation to see your original IP address. After connecting to a VPN, revisit the IP address checking website to recheck your IP address. The VPN works if the displayed IP address differs from your original IP address.

Check with ip route and ip addr show dev <wg-interface> if the routes and IPs are set as you expect. Double check that you have /proc/sys/net/ipv4/ip_forward set to 1 where needed. When injecting the VPN users into an existing network, without routing, make sure /proc/sys/net/ipv4/conf/all/proxy_arp is set to 1 .

Unreliable Monotonic Counter. WireGuard uses the system time as a reliable monotonic counter. If this jumps forward, a user might DoS their own keys, by making it impossible to later have a value larger, or an adversary controlling system time could store a handshake initiation for use later.

Yes, WireGuard can be detected. It doesn't do VPN obfuscation, mostly because of the insistence on UDP transmission mode.

WireGuard is a communication protocol and free and open-source software that implements encrypted virtual private networks (VPNs), and was designed with the goals of ease of use, high speed performance, and low attack surface.

Key takeaways from testing WireGuard vs OpenVPN speeds: On average, WireGuard was about 3.2 times faster than OpenVPN across all the locations we tested. WireGuard's performance advantage over OpenVPN is greater with nearby (low latency) servers in comparison to long-distance (high latency) server locations.

Is ExpressVPN's Lightway WireGuard? No, ExpressVPN's Lightway protocol is not WireGuard. ExpressVPN built Lightway from the ground up to meet the privacy, security, and performance needs of its users.

While quick, OpenVPN is not as quick as WireGuard. In terms of speed, WireGuard is faster than OpenVPN. OpenVPN is quite adaptable since it may employ more recent cryptographic algorithms like ChaCha20Poly1305 in addition to more well-known and proven ones like AES. Modern cryptography is used by WireGuard.
