Overview

OpenVPN is both an open-source VPN protocol and the client/server software that implements it, built on the OpenSSL library for encryption and TLS for key negotiation. It is widely used by businesses to run remote-access VPNs into an office network and by privacy-focused VPN providers as the tunneling protocol behind their apps.

On Windows, most people use it through OpenVPN Connect (a client for connecting to a provider or company VPN using a .ovpn configuration profile) rather than running a full OpenVPN server themselves. Configuring your own OpenVPN server is more involved than a mesh tool like Tailscale or WireGuard, typically requiring certificate management and firewall/port setup.

OpenVPN's main strength is flexibility and a long track record: it runs over UDP or TCP, can traverse restrictive firewalls by using port 443, and its configuration format is supported by countless routers and commercial VPN services. Its main tradeoff versus WireGuard is complexity and typically lower throughput, since WireGuard's smaller, modern codebase generally performs faster.

This is protocol/client software, not a consumer VPN service — it doesn't include servers or IP addresses of its own. You need either your own OpenVPN server or a VPN provider that supplies you with a .ovpn configuration file to connect to.

Key features

  • Encrypted tunneling over UDP or TCP using OpenSSL and TLS
  • OpenVPN Connect client for importing and running .ovpn profiles
  • Works over port 443 to traverse restrictive networks and firewalls
  • Certificate-based and pre-shared-key authentication options
  • Supported natively or via plugin by most consumer and business routers
  • Community (free) and commercial Access Server editions for different scales

System requirements

Operating system
Windows 11 and Windows 10 (64-bit and 32-bit builds available)
Configuration
A .ovpn profile from your VPN provider or self-hosted server
Permissions
Administrator rights to install the TAP/TUN virtual network adapter

How to install OpenVPN

  1. 1. Download OpenVPN Connect

    Go to openvpn.net/community-downloads/ and download the Windows installer.

  2. 2. Install the client and adapter

    Run the installer and approve the TAP/TUN virtual adapter installation prompt; this is required for the VPN tunnel to function.

  3. 3. Import a profile

    In OpenVPN Connect, import the .ovpn configuration file provided by your employer, VPN provider, or your own server setup.

  4. 4. Connect

    Select the imported profile and click Connect, entering credentials if the profile requires them.

How to use it

  1. 1. Import a new profile

    Use File > Import Profile to load an .ovpn file, then give the connection a recognizable name.

  2. 2. Check connection details

    Once connected, view the assigned VPN IP address and data transferred from the Connect client's status view.

  3. 3. Switch between profiles

    Keep separate profiles for work and personal VPN endpoints and switch between them rather than editing one profile repeatedly.

  4. 4. Troubleshoot blocked connections

    If UDP is blocked on a restrictive network, ask your server operator for a TCP port 443 profile, which is harder for firewalls to distinguish from regular HTTPS traffic.

Safety and privacy

  • Download the client only from openvpn.net; many router firmwares and VPN provider apps also bundle a licensed or compatible OpenVPN implementation.
  • The core protocol and community client are open source and independently audited over the years.
Bundled software
The official OpenVPN Connect installer for Windows installs the required TAP/TUN virtual adapter and no unrelated third-party software.
Privacy
OpenVPN Connect itself does not log your traffic; however, what a VPN connection can see about your activity depends entirely on the server operator, which may be your employer, your own server, or a commercial VPN provider — read that party's privacy policy.

Known risks

  • A misconfigured OpenVPN server (weak ciphers, exposed management interface) can undermine the security the protocol is meant to provide.
  • Installing an untrusted .ovpn profile can route your traffic through a server operator you don't trust; only import profiles from sources you trust.

What's new

    Pros and cons

    Pros

    • Open-source protocol with a long, well-reviewed security track record
    • Runs over TCP port 443 to get through restrictive firewalls
    • Broad router and VPN provider compatibility via the .ovpn standard
    • Free community edition and client
    • Flexible authentication including certificates and 2FA plugins

    Cons

    • Requires a server (your own or a provider's); the client alone does nothing without a profile
    • Generally slower throughput than WireGuard's modern implementation
    • Self-hosting an OpenVPN server involves nontrivial certificate and firewall setup
    • Configuration file management can be confusing for non-technical users

    Verdict

    OpenVPN remains a trustworthy, battle-tested choice, especially when firewall traversal or broad router compatibility matters. If you're setting up something new and speed is a priority, WireGuard's simpler design generally edges it out.

    Frequently asked questions

    Is OpenVPN free?

    The community edition and OpenVPN Connect client are free and open source. OpenVPN Inc. also sells commercial Access Server and Cloud Connexa products for organizations.

    Does OpenVPN include VPN servers I can connect to?

    No. OpenVPN is the protocol and client software; you need your own server or a VPN provider's .ovpn profile to actually connect anywhere.

    Is OpenVPN or WireGuard better?

    WireGuard generally offers faster throughput and a simpler, more modern codebase. OpenVPN offers a longer track record and the ability to run over TCP port 443, which helps on restrictive networks.

    Does OpenVPN work on Windows 11?

    Yes, current OpenVPN Connect releases support Windows 11 and Windows 10.
