Introduction

ProtonVPN is a high-security VPN service developed by CERN and MIT scientists, focused on open-source transparency and user privacy.

Setting up ProtonVPN correctly means you:

  • encrypt your traffic even over hostile networks
  • defeat censorship with Stealth/Smart protocols
  • keep metadata minimized via open-source clients
  • optionally route traffic via Tor (VPN + Tor)

Getting Started

1. Basic Fundamentals

Aspect Details
VPN Protocols OpenVPN, WireGuard, IKEv2/IPSec
Features Always-on kill switch, split tunneling, multi-hop (“Secure Core”)
Platforms Linux, Windows, macOS, Android, iOS
Open-Source Yes – apps audited and code public

2. Why Use ProtonVPN?

  • No-logs architecture – Swiss law plus technical separation of metadata.
  • Defeat surveillance – Encrypted transport, obfuscated stealth protocols.
  • Tor integration – Optional VPN-to-Tor routing with .onion exit.
  • Secure Core – Route through hardened data centers before exiting to Internet.
  • Audited apps – Full third-party audits, open code.

3. Minimum Hardware & Network

Resource Recommended
Disk ~100 MB for client install.
RAM 100–200 MB for background service.
CPU Any 64-bit CPU.
Bandwidth Based on plan; unlimited on paid tiers.
Network OpenVPN/WireGuard compatible (UDP/1194, TCP/443)

4. Installation Paths

4.1 Linux CLI Client (Debian/Ubuntu)

sudo apt update
sudo apt install -y openvpn dialog python3-pip
sudo pip3 install protonvpn-cli
protonvpn init

✅ Log in with your ProtonVPN credentials and choose your default settings.

4.2 ProtonVPN Official GUI Apps

OS Link
Windows Download ProtonVPN for Windows
macOS Download ProtonVPN for Mac
Linux GUI Deb package available
Android Google Play Store link
iOS App Store link

4.3 Docker Container (Advanced)

Unofficial but supported setups exist using OpenVPN configs inside a container:

docker run -d --name protonvpn \
  --cap-add=NET_ADMIN \
  -e PROTONVPN_USERNAME="your-username" \
  -e PROTONVPN_PASSWORD="your-password" \
  qmcgaw/gluetun:v3

✅ Configures WireGuard or OpenVPN tunnels based on ProtonVPN credentials.

5. Key Command-Line Tools & Flags

Tool Purpose
protonvpn-cli Main Linux CLI tool for connection management.
--sc Connect via Secure Core nodes.
--tor Route VPN traffic through the Tor network.
--fastest Pick fastest available server automatically.
--protocol udp/tcp Select OpenVPN protocol transport layer.

6. Securing Your VPN Setup

  1. Use Kill Switch – ProtonVPN clients offer built-in kill switch to prevent leaks if VPN drops.
  2. Prefer Secure Core – Extra hops protect against correlation attacks.
  3. Use Multi-factor Authentication (2FA) on your Proton account.
  4. Bind Sensitive Apps to VPN using split tunneling policies.
  5. Monitor VPN Status regularly with CLI (protonvpn-cli status) or logs.
  6. Run ProtonVPN via systemd to ensure auto-reconnect at boot.

7. Performance & Maintenance

Task Interval
Update ProtonVPN apps Monthly
Re-generate OpenVPN configs Quarterly (if manually imported)
Check server load Before connecting (high load → slower speeds)
Rotate login password Annually minimum

8. Advanced Integrations

Use-case Extra Steps
Always-on container VPN Use Docker + OpenVPN config or gluetun image.
Tor + VPN Connect to Tor-specific Proton servers.
WireGuard native Use Linux kernel module + manual ProtonVPN configs.

9. Troubleshooting Quick Chart

Symptom Cause Fix
Connection fails Wrong credentials or expired certificate Re-login and/or update configs.
Speed too slow Wrong server, overloaded exit node Switch to low-load server via CLI.
Cannot access Tor Not connected to Tor-enabled Proton server Use protonvpn-cli --tor option.
Kill switch stuck Client error Restart network manager / reboot machine.

10. Bottom Line

Using ProtonVPN properly gives you:

  • Military-grade encryption (OpenVPN/WireGuard)
  • No-log internet access under Swiss protection
  • Censorship bypass in hostile jurisdictions
  • Full client-side privacy (open-source clients)
  • Optional Onion routing for maximum anonymity

✅ 5 minutes setup → lifelong privacy advantage.
