Frequently Asked Questions
Common questions about wireguard vs openvpn
Both are highly secure. WireGuard uses modern cryptography and has a smaller attack surface. OpenVPN has decades of real-world hardening. Security experts consider both excellent when properly configured.
WireGuard runs in kernel space, uses efficient ChaCha20 encryption, and completes handshakes in 1 round trip. These design advantages result in significantly higher throughput than OpenVPN, with benchmarks often showing 2-3x faster speeds on high-bandwidth connections.
Choose OpenVPN when WireGuard is blocked, when you need TCP mode to bypass firewalls (especially TCP on port 443), or when connecting through restrictive corporate or school networks.
WireGuard is becoming the default for most uses due to superior speed. However, OpenVPN's firewall bypass capabilities and extensive configuration options ensure it remains valuable for specific use cases.
WireGuard is supported on all major platforms: Linux, Windows, macOS, iOS, and Android. EdgeVPN fully supports WireGuard on iOS and Android with native integration.
