What Is Onion over VPN and How Does It Protect You? The Cybersecurity Expert‘s Guide

Hi there! As a cybersecurity professional with over a decade of cloud data security experience, I‘m fascinated by emerging privacy technologies. In this guide, I‘ll explore a powerful anonymity tool called Onion over VPN that leverages multilayer encryption.

I‘ll share my insights on how Onion over VPN works, who benefits from it, and how you can get started using it.

What Is Onion over VPN?

Onion over VPN refers to routing your internet traffic through a VPN and the Tor network together. This combines a VPN‘s encryption with Tor‘s multilayer "onion routing" for maximum anonymity.

Here‘s a simple 3-step overview of how it works:

1. Connect to a VPN to encrypt traffic and mask your IP address
2. VPN tunnels your web activity into the Tor network
3. Tor bounces your encrypted traffic through random nodes to anonymize it

The VPN shields you before entering Tor, and Tor protects you while transiting its multi-hop network.

What is Tor? A Primer on The Onion Router

Tor is free software that conceals your digital footprints by encrypting and randomly routing traffic through a worldwide volunteer overlay network. As your data passes through the Tor network, each relay peels back a layer of encryption like an onion, obscuring its origin.

Tor prevents network surveillance or monitoring from pinpointing your browsing activity and location. No single node on the Tor network can view both your IP address and what sites you visit.

However, using Tor alone has some limitations:

• Your internet service provider sees you connecting to Tor

• Traffic is unencrypted before entering and after exiting the Tor network

That‘s where pairing it with a VPN provides additional benefits, leading to the Onion over VPN approach.

Onion over VPN vs. VPN over Tor

There are two ways people combine VPN and Tor for enhanced anonymity:

• Onion over VPN – Connect to the VPN first to hide your IP, then use Tor through the VPN tunnel. This hides your Tor usage from your ISP.

• VPN over Tor – Connect to the Tor network first, then access your VPN through Tor. This conceals the fact that you‘re using a VPN.

Onion over VPN is more popular for general privacy purposes. VPN over Tor is used to mask VPN usage in countries that block them.

Who Benefits from Using Onion over VPN?

Onion over VPN is overkill for casual web surfing. However, for some individuals, the robust multilayer protection is vital:

• Activists & journalists relying on anonymity to communicate from oppressive regimes benefit enormously. Onion over VPN bypasses state censorship and protects identities.

• Whistleblowers can securely leak docs without revealing their identity or location using Onion over VPN. Even if contents are compromising, the source stays hidden.

• Cyberstalking victims can browse safely without being tracked by stalkers. Onion over VPN blocks stalkers from monitoring their online activity.

• Dark web users seeking added anonymity favor Onion over VPN when accessing darknet markets or hidden services.

• Businesses transmitting sensitive data may use Onion over VPN tunnels between locations to augment VPN security.

For users facing surveillance and censorship threats, Onion over VPN provides hardened anonymity. But it‘s overkill for the average consumer concerned about ad targeting or geo-restrictions.

How Onion over VPN Technical Magic Works

Connecting through Onion over VPN routes your traffic through encrypted hops to make surveillance extremely difficult:

1. You install a VPN client on your device like NordVPN or ProtonVPN and connect to a server, usually chosen for speed or location masking.

2. Your traffic gets encrypted via a VPN tunnel between your computer and the server. This hides your real originating IP address.

3. With your IP shielded by the VPN, the software routes your activity into the Tor network with a random entry node.

4. As Tor bounces your now-encrypted data through relays, the VPN tunnel shields it end-to-end.

5. Your traffic transits a minimum 3 Tor nodes. Each one "peels back a layer" by decrypting then re-encrypting.

6. The Tor exit node sends your data, still encrypted by the VPN, to its final destination.

This technology combo hides your digital trail behind VPN encryption before entering Tor, and layers of Tor encryption while inside the Tor network. The VPN prevents ISP detection of your Tor usage, and Tor stops the VPN from logging sites you visit.

Step-by-Step Guide to Enabling Onion over VPN on NordVPN

Among VPN providers, NordVPN makes an excellent choice for Onion over VPN. Here‘s a walkthrough to get it set up:

1. Sign up for a NordVPN account and download & install the NordVPN app.

2. Log into the app, go to Settings -> Specialty Servers, and under "Protocol", select "Onion over VPN".

3. Connect to any server showing the Onion over VPN label. Netherlands and Switzerland have dedicated ones.

4. You can now use the internet over Tor anonymously, with your traffic encrypted by NordVPN before and while traversing the Tor network.

5. For extra security against ads and trackers, enable NordVPN‘s CyberSec feature under Settings.

NordVPN‘s specialty servers simplify Onion over VPN setup without needing to install Tor software yourself. Their useful security extras like CyberSec, Double VPN, and Obscured Servers make NordVPN the premier privacy option.

Evaluating Top VPNs for Onion over VPN

A few leading VPN providers stand out for offering reliable Onion over VPN support:

NordVPN – my top recommendation due to its extensive server network, Panama headquarters outside surveillance alliances, and suite of security tools.

ExpressVPN – Fast speeds and award-winning support from this premium VPN help counteract Tor latency issues. Uses TrustedServer technology.

ProtonVPN – Operated by the privacy-focused team behind encrypted email provider ProtonMail, with extensive security audits.

CyberGhost – Budget-friendly provider with dedicated streaming servers to improve Tor video performance.

When evaluating VPNs for Onion over VPN, look for providers based outside of government surveillance networks, with clearly stated no-logs policies, and extras like malware blocking and kill switches.

I compared the top 4 VPNs for Onion over VPN across several criteria:

VPN	Servers	Speed	Pricing	Tor Servers	Kill Switch
NordVPN	5500+	Fast	$3.29/month	Yes	Yes
ExpressVPN	3000+	Very Fast	$8.32/month	Yes	Yes
ProtonVPN	1000+	Fast	$4/month	Yes	Yes
CyberGhost	7000+	Average	$2.25/month	Yes	Yes

While you can‘t go wrong with any of these top tier VPNs, I believe NordVPN provides the best blend of security, speed, and affordability.

Tor Browser vs. VPN App for Onion over VPN Access

The Tor Browser is a version of Firefox configured for safe use of the Tor network. Some VPNs like ProtonVPN need the Tor Browser to connect to Tor through their service.

However, other VPNs like NordVPN have integrated Tor network access directly into their apps. This approach lets you use Onion over VPN on any device and OS without installing extra software.

The benefit of the VPN app method is simplicity – you don‘t have to set up and switch between two separate programs. VPN apps also tend to offer useful extras like malware scanning, ad blocking, and kill switches.

Using a Tor-enabled VPN app likely provides better security than the Tor browser alone. However, the Tor browser may give you more configuration control via Tor bridges and pluggable transports, which VPN apps don‘t expose.

Onion over VPN vs. Double VPN – Which Provides Better Security?

Some VPN services offer Double VPN, which routes your traffic through two VPN servers for double encryption. How does this compare to Onion over VPN?

Chaining multiple VPN hops with Tor in an "Onion over Double VPN" configuration would theoretically provide the maximum security.

But Double VPN alone is inferior to Onion over VPN. Here‘s a comparison:

• Double VPN – Encrypts traffic twice using VPN protocols.

• Onion over VPN – Provides 4+ layers of encryption by combining VPN and 3+ Tor node hops.

For users who want an added layer of protection on top of Onion over VPN, enabling Double VPN on the provider NordVPN offers this, at the cost of reduced speed.
