Choose Location
Industry Standard
OpenVPN is the gold standard trusted by enterprises, governments, and millions of users worldwide. Over 20 years of security audits, continuous development, and battle-tested reliability in production environments.
Military-Grade Security
AES-256-CBC encryption with RSA-4096 key exchange and SHA-512 HMAC authentication. Perfect forward secrecy ensures past sessions remain secure even if keys are compromised. NSA-proof protection.
Universal Compatibility
Native support across all platforms: Windows, Mac, Linux, Android, iOS, and routers. Official OpenVPN client or third-party apps like Tunnelblick, OpenVPN Connect, and OpenVPN for Android.
Why OpenVPN?
The most trusted VPN protocol in 2026
Open Source & Audited
Completely open-source code reviewed by security experts worldwide. No backdoors, no hidden vulnerabilities. Regular security audits by independent firms ensure cryptographic integrity and implementation correctness.
UDP & TCP Support
Flexible protocol support—UDP for maximum speed and low latency, TCP for reliability on restrictive networks. UDP port 1194 for optimal performance, TCP port 443 for firewall bypass and compatibility.
Perfect Forward Secrecy
TLS-based key exchange with ephemeral Diffie-Hellman ensures unique session keys. Even if your private key is stolen, past VPN sessions cannot be decrypted—protecting historical data from retroactive surveillance.
Advanced Features
Compression for bandwidth saving, split tunneling for selective routing, DNS leak protection, IPv6 support, and automatic reconnection. Full control over routing, traffic shaping, and connection behavior.

About OpenVPN Technology
OpenVPN is the world's most popular open-source VPN solution, originally released in 2001 and now trusted by over 60 million users globally. Unlike proprietary VPN protocols, OpenVPN's complete transparency allows security researchers and cryptographers to audit every line of code, ensuring no backdoors or vulnerabilities remain hidden. This open development model has made OpenVPN the de facto standard for enterprise VPN deployments.
The protocol's security architecture is built on industry-standard cryptographic libraries—specifically OpenSSL and mbed TLS. Our servers use AES-256-CBC encryption, which is the same cipher suite approved for TOP SECRET government communications by the NSA. The key exchange relies on RSA-4096 or Elliptic Curve Diffie-Hellman, providing perfect forward secrecy that protects past sessions even if encryption keys are later compromised. SHA-512 HMAC authentication prevents packet tampering and replay attacks.
OpenVPN's flexibility is unmatched. It operates in two modes: UDP for optimal performance and low latency (ideal for gaming and streaming), or TCP for maximum reliability on restrictive networks (useful for corporate firewalls that block UDP). When running on TCP port 443, OpenVPN traffic is indistinguishable from regular HTTPS, allowing it to bypass most network restrictions. Advanced features include compression (LZO or LZ4), split tunneling to route only specific traffic through the VPN, and DNS leak protection.
Client availability is another major advantage. Official OpenVPN Connect apps are available for all major platforms, while third-party implementations like Tunnelblick (Mac), Viscosity (Mac/Windows), and OpenVPN for Android provide additional features and customization. The protocol is also natively supported by many routers running OpenWrt, DD-WRT, or Tomato firmware, enabling network-wide VPN protection.
Our OpenVPN servers run on 10Gbps infrastructure with NVMe SSD storage and automated certificate management. Each account includes both UDP (port 1194) and TCP (port 443) configuration files, unlimited bandwidth, 3-day active period, and support for concurrent connections from multiple devices. Compatible with all OpenVPN 2.4+ clients including OpenVPN Connect, Tunnelblick, Viscosity, and OpenVPN GUI.
