Why you might want to have two VPNs installed

Informatec Digital » Resources » Why you might want to have two VPNs installed

Using a VPN has become almost mandatory if you connect to public Wi-Fi networks , work remotely, or are simply concerned about what your internet provider and websites know about you. But when you start digging deeper, the question quickly arises: does it make sense to have two VPNs installed on the same device, or even try to use them simultaneously?

The short answer is that installing multiple VPNs can be a good idea , but running two tunnels simultaneously usually causes more problems than it solves. Furthermore, another often-confused concept comes into play: Double VPN or MultiHop . This isn't simply having two separate applications; it's an advanced feature that doubles the encryption by passing through two linked servers.

What does it really mean to have two VPNs installed?

It's important to distinguish between two completely different situations : having several VPN applications installed on your mobile phone or computer, and trying to get two VPN connections working simultaneously. The first is usually perfectly feasible; the second, in practice, almost always ends in network conflicts.

When we talk about "having two VPNs" on the device , we usually mean having several apps (for example, NordVPN and Surfshark) ready to use, but only one active at any given time . The operating system creates a single virtual interface through which traffic is routed when you connect to a service, and when you switch VPNs, a different tunnel is simply established.

However, running two tunnels simultaneously is a different story . Each VPN client tries to take control of the routing and firewall rules; as they compete with each other, errors occur, connectivity is lost, or one app forces the other to disconnect. Many services, in fact, detect that a tunnel is already active and block the second connection.

This distinction is key to understanding why you'll see clear advantages when installing more than one VPN as a "plan B," but also why it's not advisable to set up home configurations with two simultaneous tunnels, except in very specific and controlled cases.

Reasons to have more than one VPN installed (but not simultaneously)

Having multiple VPNs on your computer makes a lot of sense if you use them for different things or want to always have a backup ready in case your main one fails. It's not about chaining them together, but about choosing the one that best suits your needs at any given time.

One of the most common reasons is to use each VPN for a specific purpose . Not all providers offer the same features: some prioritize speed for streaming and online gaming, while others focus on more secure protocols or strict privacy policies. For example, you might reserve a VPN with very robust encryption and good security audits for public Wi-Fi networks, and use a lighter, faster one for Netflix, Disney+, or content platforms from other countries.

It's also useful in travel or constantly mobile scenarios . If you frequently connect from cafes, airports, or hotels, and also need to access catalogs from other countries or play online games, having a couple of services installed gives you the flexibility to quickly switch when one experiences performance issues or freezes.

Another advantage of having multiple VPNs is the total number of servers and countries you can access. Each provider has its own network: some cover Asia better, others Latin America, and still others have many nodes in Europe. With two separate accounts, you multiply the available combinations and have more options if a server is overloaded or if a specific region isn't listed by a particular service.

Furthermore, having two VPNs allows you to make real-world comparisons of speed and stability . You can run speed tests (download, upload, and ping) at different times of day and depending on your usage (gaming, video calls, 4K streaming, torrents) and choose the one that performs best in each case. No single VPN is "always the fastest"; factors such as time of day, server congestion, and the route your traffic takes all play a role.

Finally, having more than one VPN installed is very useful for bypassing blocks . Many websites, streaming platforms, and even online stores maintain blacklists of IP addresses used by VPNs. If a service stops working because it has blocked the ranges of a VPN, you can disconnect it, open the other application, and try a different server to continue browsing without restrictions.

Using two VPNs at the same time: problems and technical limitations

Trying to activate two VPNs simultaneously on the same laptop or mobile device is a completely different matter. This enters the realm of "concurrent connections," which are not typically supported cleanly at the operating system and VPN client levels.

Most desktop VPN clients only allow one active tunnel per device . When you initiate a connection, that app takes control of the virtual interface (tun/tap, secure network adapter, etc.), applies its own routing table, and establishes encryption rules. If you start a second VPN, the system routes will overlap, or the second application will detect that a tunnel is already in place and refuse to connect.

Even if you can sometimes get both VPNs to report as "connected ," the result is usually chaos: traffic goes through one tunnel when the application thinks it's going through another, DNS servers get mixed up, routes are duplicated, and you end up unable to access either internal company resources or external services. In some cases, one VPN directly disables the other to prevent data leaks.

From a performance standpoint, it's not exactly ideal either . Each VPN tunnel encrypts and decrypts all your traffic, which already introduces an overload on CPU, memory, and bandwidth. If you overlap two full connections, latency increases, download and upload speeds drop significantly, and battery consumption on laptops and mobile devices skyrockets. We're talking about additional battery reductions of between 2% and 8% just from the extra encryption, depending on usage.

Furthermore, many VPN apps aren't designed to run in the background . Some providers, like Surfshark, for example, will issue warnings if they detect another active VPN service and may block the connection for security reasons. And even if you manage to get both working, you'd be paying for two subscriptions for an unstable setup that you could easily replace with a single VPN that has built-in MultiHop or Double VPN functionality.

Double VPN or MultiHop: two servers, one provider

When you hear about “using two VPNs,” it often refers to the Double VPN (also called MultiHop) feature offered by some advanced services. This isn't the same as installing two separate apps: it involves routing your traffic through two servers from the same provider , in a chained fashion, adding a second layer of encryption.

With a standard VPN, your connection is encrypted once and goes directly to a server in your chosen country. That server decrypts the traffic, hides your original IP address, assigns you a new IP address, and sends it to your destination (the website, banking app, online game, etc.). The site you're visiting only sees the VPN server's IP address.

With Double VPN, the process involves two hops . First, your device connects to an entry server, where your traffic is encrypted and assigned an initial IP address. From there, the data—now encrypted—is re-encapsulated and sent to a second VPN server. This second node applies another layer of encryption, changes the outgoing IP address again, and only then sends the traffic to its final destination.

The result is that you appear to websites with the IP address of the second server , and at the same time, there's an additional layer of encryption and an intermediate hop that makes reconstructing the circuit extremely difficult. Even if someone were to compromise one server, they would still need to break another layer of encryption and correlate the traffic between the two nodes.

Services like NordVPN include pre-set Double VPN combinations (for example, Hong Kong → Taiwan), so you simply choose the server pair and the application handles setting up the double tunnel. Others, like Surfshark, allow you to customize MultiHop and choose your preferred entry and exit countries. Private Internet Access goes a step further by using proxies like Shadowsocks or SOCKS5 to add extra obfuscation.

Advantages of Double VPN versus a single VPN

The main benefit of using Double VPN is taking privacy to the highest level . With two layers of encryption and two IP addresses in potentially different countries, tracking your traffic and linking it to you becomes extremely difficult for anyone, whether it's your internet provider, potential middlemen, or even government agencies with ample resources.

This type of feature is specifically designed for high-risk users : journalists covering sensitive topics, political activists, whistleblowers, or users connecting from areas with highly censored and monitored content. For such sensitive tasks, a simple VPN may not be sufficient, while double-hop protection adds a layer of security.

Another important advantage is that your real location is completely obscured . If you connect through a server in country A and connect through another in country B, online services will only see the IP address from B. No one can deduce which country you're actually connecting from unless they have complete control over intermediate infrastructure and manage to decipher and correlate times and other factors—something unrealistic in everyday life.

Of course, you also continue to enjoy all the typical advantages of a VPN : protection against unsecured Wi-Fi networks, blocking ISP monitoring, access to streaming catalogs from other countries (if the provider allows it with Double VPN), anonymity in P2P downloads, etc. You simply add an extra layer to all of that.

In some services, Double VPN comes with additional features such as ad and malware blockers, protection against malicious websites, and even alerts if your data is leaked on the dark web. NordVPN, for example, combines 10 Gbps servers with Double VPN, a kill switch, and strict no-logs policies to make the double hop as smooth as possible in terms of speed.

Disadvantages and costs of using Double VPN

The biggest trade-off with a Double VPN is speed . Any VPN already introduces some latency and a slight performance loss due to encryption and the distance to the server. If you add a second node, the traffic takes a longer path and is encrypted and decrypted twice, so ping increases and download/upload speeds drop even further.

In latency-sensitive tasks—like online gaming, video calls, or 4K streaming—the difference is noticeable . You can still use it, but response times will be worse, and you're more likely to experience micro-cuts or buffering if your original connection isn't very strong. Many providers recommend not using Double VPN for everyday tasks, reserving it only for when you truly need that extra layer of privacy.

There's also an impact on device resource consumption . Processing two layers of encryption and data transfer demands more CPU, more network activity, and, in the case of mobile phones and laptops, more battery power. It's not dramatic in all cases, but if you spend hours using Double VPN with Wi-Fi and the screen on, you'll notice the battery drains faster.

Another practical limitation is that Double VPN server pairs are much smaller than the standard country list. While a VPN might offer dozens of single-hop locations, it may only have a dozen fixed MultiHop combinations, restricting your ability to "shame" specific countries while using double encryption.

Furthermore, almost no free VPNs include Double VPN . It's an advanced feature that requires more infrastructure, bandwidth, and processing power, so it's usually restricted to paid services. ExpressVPN, for example, despite being a very robust VPN, doesn't include this feature, while others like NordVPN, Surfshark, and Private Internet Access do.

Is it possible to create your own Double VPN with two different providers?

On paper, nothing prevents you from trying to daisy-chain two VPNs from different providers : first connect to one with a specific protocol (for example, OpenVPN) and, once established, set up another with IKEv2 or WireGuard on top. In theory, you would have two layers of encryption, and the final IP address would be that of the second service.

In practice, achieving a stable and secure setup isn't so simple . Many VPN clients don't tolerate another application capturing encrypted traffic; if they detect another VPN, they'll display errors, disconnect repeatedly, or leave inconsistent routing. Furthermore, if one of the two providers maintains extensive logging and lax privacy policies, you'd be negating the other's added protection.

A minimum requirement for setting something like this up is that both providers be highly reliable and privacy-focused , with robust audits and clear no-logs policies. It's also essential that they support different protocols so they don't compete for the same ports or interfaces. For example, you could use OpenVPN in the first VPN and IKEv2 in the second to minimize conflicts.

Even with those adjustments, there's no guarantee it will be usable on a daily basis . It's common for the second VPN to try to reconnect frequently, for the entire connection to drop when switching networks (from Wi-Fi to mobile data, for example), or for certain applications to fail to properly detect the new IP address. And, of course, paying for two subscriptions for such a fragile solution is usually not worthwhile compared to subscribing to a single VPN with integrated MultiHop.

For this reason, the general recommendation from experts is simple : if you want Double VPN, choose a provider that offers it natively, with its tested and optimized server pairs. If you just want flexibility, install two different VPNs, but always use only one at a time.

Practical alternatives to using two VPNs at the same time

If you're looking for more security or flexibility without setting up contraptions with two simultaneous tunnels , there are several much more stable configurations that can make sense in everyday life.

A common approach is to combine a full VPN application with a browser extension . You connect the desktop (or mobile) app to one server and, within the browser, activate a browser extension from another provider that connects to a second server. This way, browser traffic passes through two layers, while the rest of the system's applications use only the first VPN.

This approach has a clear limitation : double protection only applies to traffic passing through that specific browser. If you use an external torrent client, media player, or any other app, they will only see one VPN tunnel, not two. Even so, it can be useful for very specific tasks performed from within the browser.

Another interesting alternative is to install the VPN on your router and also use a VPN app on your device . This way, all home traffic first passes through the router's tunnel, and then, if you activate the VPN on your laptop or mobile device, that device adds a second layer. It's a kind of "homemade" Double VPN, but distributed between the router and the device.

You can also experiment with virtual machines : one VPN runs on the host system and another inside the virtual machine. It's a more complex setup and not without its problems, but it can be useful for lab testing or isolating environments. However, it does require knowledge of networking and virtualization to avoid inadvertently opening insecure paths between the two layers.

In almost all cases, the key is to understand exactly what you want to achieve . If you're simply looking to access your company's network simultaneously through a corporate VPN and an external provider (for example, AWS with its own client), you'll need to review the split tunneling policies, routing, and security rules of your IT department, because enterprise customers typically block these kinds of configurations by default.

Many enterprise solutions allow for split tunneling , which is another piece of the puzzle. With split tunneling, only traffic destined for internal networks (for example, 10.0.0.0/8 or 192.168.0.0/24) travels through the company's secure tunnel, while the rest goes directly to the internet. Properly configuring this splitting and ensuring that no "backdoor" is opened through which unauthorized traffic could enter the tunnel is part of the network administrator's job.

When is it really worth having two VPNs installed?

After all of the above, the general idea is simple : having multiple VPNs installed can be very useful; trying to use them simultaneously, however, is usually not. The key is finding scenarios where this dual installation gives you leeway and doesn't complicate things.

If you're a user who frequently changes your use case —traveling, international streaming, gaming, remote work with sensitive data—you can really benefit from having one VPN optimized for speed and another designed for extreme privacy, Double VPN, and obfuscated servers. That way, you can simply press the appropriate button depending on what you're doing.

It also makes sense if you're already subscribed to a provider for a specific reason (for example, because your company recommends or requires it for remote work) and you want to maintain a second VPN more geared towards leisure, streaming, or P2P. In this case, you won't use them simultaneously, but you can clearly separate work and personal life simply by disconnecting one and activating the other.

For those who live in or frequently travel to countries with heavy censorship , having multiple VPNs installed increases the likelihood that at least one will work at any given time. Some governments block popular IPs and protocols; if one service goes down, switching to another can be the difference between being able to use Google and social media or being digitally cut off.

Finally, if you're concerned about maximizing security , the ideal combination is usually: a single provider with Double VPN for critical moments, and several backup services installed to respond to blocks or performance drops. You still only use one tunnel at a time, but with the peace of mind of having alternatives readily available.

Once you understand the differences between installing multiple VPNs, running two simultaneous tunnels, and taking advantage of features like Double VPN or split tunneling , it's much easier to design a configuration that gives you privacy, performance, and flexibility without getting bogged down in compatibility issues or wasting time and money on fragile setups that barely provide any real additional protection.
