什么是OpenVPN？

OpenVPN is a virtual private network protocol that creates a secure tunnel for your 数据 traffic.

Think of it like a locked highway for your internet. Only you have the key.

Here’s the simple version:

The OpenVPN protocol uses SSL/TLS encryption to protect everything you send online. It wraps your data in extra layers of security. This keeps hackers, your internet service provider, and snoopers out.

OpenVPN supports both TCP (transmission control protocol) and UDP (user datagram protocol) for sending data. TCP ensures all data packets are delivered in order. This makes it more reliable but slower. UDP is faster than TCP but does not guarantee delivery order.

Unlike older VPN protocols like PPTP, OpenVPN gives you much stronger encryption. It supports encryption ciphers like AES-256, ChaCha20, and even Blowfish. The open source OpenVPN protocol lets anyone inspect the code. That means thousands of developers check it for security flaws.

OpenVPN uses configuration files with a .ovpn extension to set up connections. These are simple 文本 files you can edit easily. You can use OpenVPN on Windows, macOS, Linux, 安卓, and iOS. It works on almost every operating system out there. It connects virtual private networks across the globe.

Many VPN services like Private Internet Access (巴基斯坦国际航空公司) and ExpressVPN use the OpenVPN protocol in their apps. That shows how trusted this open source VPN protocol really is.

OpenVPN是谁创建的？

詹姆斯·约南 created the OpenVPN protocol in 2001.

He later teamed up with Francis Dinha to start OpenVPN Technologies in 2002. Dinha grew up in Iraq under harsh conditions. He knew the value of privacy and secure connections.

Today, OpenVPN has:

• Over 60 million downloads worldwide
• More than 10,000 business customers
• Users in nearly every country

The OpenVPN company is based in Pleasanton, California. Companies like Tesla and Google use their software to protect sensitive data.

OpenVPN 的主要优势

Here’s what you actually get when you use OpenVPN:

• 坚如磐石的安全保障： OpenVPN uses the OpenSSL library for up to 256-bit encryption. It’s one of the safest VPN protocols available. Your sensitive data stays protected at all times.
• Works through firewalls: OpenVPN is known for its ability to handle firewalls and NAT gateways. Most VPN protocols get blocked. OpenVPN slips right through using its custom security protocol.
• Full control over your setup: You can run your own VPN server. You choose the encryption ciphers, authentication methods, and encryption keys. No other VPN protocol gives you this much freedom.
• 跨平台支持： OpenVPN works on Windows, macOS, Linux, Android, and iOS. It even runs on lesser-known systems like Solaris and DD-WRT routers. Your mobile devices are covered too.
• Free and open source: The OpenVPN community edition is completely free. Anyone can inspect the code. A global community of developers keeps it safe and up to date.
• Scales with your business: OpenVPN can handle anything from one remote access user to complex site-to-site connections for large companies. It grows as you grow.
• Perfect Forward Secrecy: OpenVPN includes Perfect Forward Secrecy. This means your encryption keys change regularly. Even if one key gets stolen, your other data stays safe.

Best OpenVPN Features

Here are the standout features that make OpenVPN software worth your attention in 2026.

1. 安全远程访问

This is what most VPN users need. OpenVPN lets your team connect to the office network from anywhere.

The OpenVPN access server handles all the heavy lifting. Your VPN clients get a secure tunnel to your private network. Every VPN connection uses strong encryption algorithms to protect data traffic.

I set this up for a client with 15 remote workers. It took about 30 minutes. The OpenVPN connect app made it easy for the whole team.

2. 安全的物联网通信

Got smart devices on your network? They need protection too.

OpenVPN creates secure connections between IoT devices and your servers. This stops hackers from hijacking your smart devices.

Tesla uses OpenVPN to protect its vehicles from being hacked. If it’s good enough for Tesla, it’s good enough for your business. The OpenVPN protocol handles this with ease using encryption protocols and public key infrastructure.

3. 创建对 SaaS 应用程序的安全访问

Your team uses cloud apps every day. But are those connections safe?

OpenVPN wraps your SaaS traffic in a secure tunnel. This means your internet access to apps like Salesforce, Slack, and Google Workspace stays encrypted.

The OpenVPN client software handles this in the background. Your team won’t even notice it’s running. But your data stays protected from your internet service provider and other snoopers.

4. 站点间联网

Got multiple offices? OpenVPN connects them all.

Site-to-site VPN tunnels link your private networks together. It’s like having one big secure network. Data flows between OpenVPN servers at each office without touching the public internet.

This is where OpenVPN really shines. Creating VPN tunnels between sites is fast and reliable. The OpenVPN server at each location handles the connection. OpenVPN works well for this because it supports both IPv4 and IPv6 traffic.

5. 强制执行零信任访问

Zero Trust means “never trust, always verify.” Every user must prove who they are.

OpenVPN supports this with strong authentication methods. You can use digital certificates, user credentials, and multi-factor authentication. The hash message authentication code (HMAC) feature adds another layer of security.

This HMAC firewall protects against unauthorized access. Authentication OpenVPN handles is strong. It uses the secure sockets layer and public key infrastructure to verify every connection.

6. DNS Security and Content Filtering

Bad websites can infect your network. DNS security stops that.

OpenVPN filters out dangerous content before it reaches your team. This blocks malware, phishing sites, and harmful downloads.

I tested this feature with known malicious URLs. OpenVPN blocked every single one. Your VPN users stay safe without thinking about it. This works across all your OpenVPN connections.

7. CloudConnexa (Cloud-Delivered VPN)

Don’t want to manage your own VPN servers? CloudConnexa does it for you.

It’s OpenVPN’s managed VPN service. You get all the security without the server headaches. Most VPN providers charge extra for this. OpenVPN includes it in their Growth plan.

Setup takes about 10 minutes. Your VPN clients download the OpenVPN connect app. Then they’re good to go. This is the best option for small teams who want an OpenVPN compatible service without the fuss.

8. SaaS Protection

Your cloud apps need a bodyguard. OpenVPN is that bodyguard.

SaaS Protection wraps all your cloud traffic in encrypted VPN tunnels. This covers apps like Microsoft 365, Google Workspace, and more.

The OpenVPN protocol uses SSL/TLS and the OpenSSL library to encrypt everything. Your data stays invisible to hackers. Even if someone intercepts your connection, they can’t read your encrypted data. The TLS auth feature adds extra protection.

OpenVPN Pricing

OpenVPN keeps pricing simple. Here’s what each plan costs:

免费试用： Yes — both Access Server and CloudConnexa offer free plans with limited connections. No credit card needed.

退款保证： You can cancel anytime. Unused funds get credited to your account.

Is OpenVPN Worth the Price?

At $7/month per connection, OpenVPN is a solid deal for business VPN needs. Most VPN providers charge similar rates. But OpenVPN gives you more control.

The OpenVPN community edition is completely free. That’s perfect if you have the tech skills for manual configuration.

You’ll save money if: You need a self-hosted VPN server for your business. The Access Server runs on your own hardware. No monthly fees beyond the license.

You might overpay if: You just want personal browsing protection. A consumer VPN service like NordVPN or 冲浪鲨 costs less for that use case.

Can You Trust OpenVPN?

Security matters. Here’s what you should know about this virtual private network:

加密： OpenVPN uses AES-256 and ChaCha20 encryption ciphers. These are the same encryption algorithms used by banks and governments. The OpenSSL library powers all encryption.

隐私政策： OpenVPN is SOC 2 and HIPAA compliant. They perform ongoing security assessments. Your data stays private.

Audits: OpenVPN’s open-source nature means anyone can inspect the code. Thousands of developers review it regularly. This makes it more trustworthy than closed-source VPN protocols.

Company Location: Based in Pleasanton, California, USA. The US has strong privacy laws but is also part of the Five Eyes alliance. For most business use, this isn’t a concern.

My take: OpenVPN was created in 2001 and is widely regarded as safe and reliable. It offers better security than most VPN protocols. The open source code means no hidden backdoors. I trust it for my clients’ sensitive data.
