The internet is a fantastic place, but there are risks associated with heading online. From identity theft to phishing scams, it’s vital to keep ourselves protected online.
VPN and SSH technologies are designed to protect us while we complete our online tasks. The technologies work in pretty similar ways but don’t do the same thing. Let’s take a deeper look at both of them.
SSH vs. VPN: Overview
VPNs and SSH systems both create secure “tunnels” for your data to travel through. These tunnels ensure that nobody other than the intended recipient can view or alter your data.
However, while a VPN connection works at an operating system level (pulling all traffic through the secure pathways), an SSH connection works at the application level.
In other words, SSH tunneling will secure data exchanged between you and a remote server you have access to, while a VPN works to encrypt your entire network.
What is SSH?
SSH stands for “secure shell.” It’s a technology that allows you to connect to a device by using “tunnels” that encrypt, secure, and disguise your traffic.
This means you can access network resources from practically anywhere. It’s particularly useful when you want secure communication between your computer at work and at home.
How does it work?
Besides letting your devices communicate and access resources, an SSH tunnel protects data. It does this with strong encryption capabilities, password authentication, and public-key authentication. This means that your data is safe while the SSH client forwards it to the recipient device.
You need some technical knowledge to set up and use an SSH, which can be quite complicated. Of course, setting up a VPN from scratch would take more effort, but lucky for you, you can solve that by getting a VPN app – no coding required!
It’s also important to remember that SSH tunnels must be set up per application and you need to use terminal commands (rather than an app) to control them.
SSH Pros & Cons
- Features a less complicated server setup process for tech-savvy people than VPN connections do.
- Provides strong encryption to protect users from threats. These could include DNS leaks, IP address spoofing, IP source routing, data theft, and more.
- SSH tunnels make it simple to access a remote server or operate a remote terminal session between devices.
- Inexperienced users may find setup and management difficult.
- Every application you want remote access to will need an individual SSH connection. This can get complicated if you want to encrypt all of your internet traffic.
What is a VPN?
VPN stands for “Virtual Private Network.” This technology protects your privacy online by routing your traffic through an encrypted tunnel.
This means that even if you connect to the internet using public Wi-Fi or an unsecured hotspot, you can rest assured that your data is secure within the VPN tunnel.
With a VPN, you can connect to a remote server from anywhere in the world with a simple click. This allows you to bypass restrictive firewalls or oppressive censorship rules, avoid geographical restrictions*, and browse the internet safely.
How does it work?
VPN encryption disguises the traffic of an everyday internet user by routing it through a secure tunnel.
In other words, your data will travel from your computer to its destination by using a secure tunnel. The tunnel will disguise your traffic to make it look like it’s coming from a different location: protecting your identity and security online.
These features are great for checking in on your local football team or avoiding internet throttling from your data provider, as your provider cannot see what you’re doing online, they can no longer throttle your speed.
The VPN will also encrypt all traffic shared between the networks, shielding you from prying eyes.
*Disclaimer: Surfshark does not encourage using a VPN in any way that would potentially violate the Terms of Service of other service providers.
VPN Pros & Cons
- An active VPN will immediately encrypt all traffic coming from your device. No coding or server controls are required.
- Premium VPN software offers worldwide server locations, allowing you to appear as though you’re anywhere in the world!
- VPNs are accessible to anyone – even if you don’t have any technical skills. Many even feature a “Quick Connect” button that allows you to secure your data immediately.
- VPNs secure all your network traffic, protecting your identity, data, and location, even when using unsecured public Wi-Fi networks.
- VPNs help hide your network usage, meaning your data provider can’t throttle your data.
- A VPN server can be complicated to set up at the server level (although if you’re using a premium VPN service like Surfshark, you won’t need to worry about this).
- It is crucial to be wary of free VPN providers as they may provide weak encryption or even sell your data.
SSH vs. VPN: Benefits
So, an SSH tunnel will allow you to access another computer even when you’re nowhere near it.
With an SSH secure shell, you’ll generally be connected to a specific machine, and only the data you choose will be transferred. With a VPN, you’ll be effectively connected to a network.
An SSH tunnel has a command-line focus. If you’re tech-savvy, this provides more flexibility and an easier technical setup process.
Most VPN users can simply download an app or extension to get started right away. So, you don’t need to worry about complicated setup procedures.
If you know scripts/coding, you can use an SSH tunnel to access files immediately. This makes it an excellent file-syncing solution.
If installed at the router, all web browsing traffic appears to come from the location selected by the VPN client. Depending on your VPN provider, this could be one of the thousands of locations worldwide. No need to set up individual apps or be restricted by geo-blocking.
An SSH server can manage remote devices, test software, install updates, and more.
A VPN connects your device to a server that can make it look like you’re anywhere else in the world.
A casual user can use the SSH tunnel to manage their music library, emails, or personal files even when away from their device.
VPNs often have dedicated apps. This makes it easy for non-technical users to get started with a few clicks!
SSH tunnels use strong symmetric encryption and hashing algorithms to ensure privacy. This provides a secure tunnel for accessing a device on the internet.
VPNs use strong encryption and hashing algorithms to ensure privacy. This provides a secure tunnel for all internet traffic.
Is SSH better than a VPN?
SSH tunnels are not better than a VPN.
However, that doesn’t mean that SSH tunnels aren’t helpful. For example, SSH only works per app. This means an SSH client could set up tunnels for specific apps to communicate with another device but maintain private networks for others.
Comparatively, a VPN works as a virtual network adapter, pulling all your information through the selected tunnel (though you can always enable Split Tunneling if you only want to protect one app). This saves time and effort and adds extra security to your activities.
Do I need a VPN for SSH?
The simple answer is no; you don’t need to use a VPN for SSH. However, you might want to…
Because these aren’t competing technologies, you can connect to a virtual private network (VPN), then use an SSH server to:
- Test software;
- Manage a music library;
- Download free ebooks while away from your home network.
This adds an extra layer of security to your online activities and ensures you’re well protected no matter where you log on.
Fundamentally, using a VPN and SSH system together won’t make you more secure. Yet, it can bring more control options in some circumstances.
Is SSH tunneling safe?
Simply put, yes, SSH tunneling is safe.
VPN vs. SSH tunnels both encrypt and secure all data and information passing through.
Get the right tool for you.
A VPN is likely to be the best option for most day-to-day users.
Although the initial setup of a VPN is more complicated than building an SSH tunnel, most VPN users will benefit from systems that are already set up. So, all they need to do is download the app, log in to their account, and select a location. Meaning this isn’t a concern unless you plan to set up your own VPN server (unlikely).
That said, IT admins or anyone who needs to access a specific computer remotely might benefit more from SSH or a combination of both technologies to provide complete, encrypted access to their devices. It all comes down to your personal needs.
Is SSH safer than VPN?
No. When looking at the smaller scale, SSH and a good VPN service are equally safe. However, since a VPN will protect your entire device or even your entire network, it is often more convenient to have.
Can you use SSH as a VPN?
An SSH tunnel cannot replace a VPN, but it does have one similar use case. If your primary need for a VPN is accessing your work device so you can share resources, you can also do this with an SSH tunnel. This gives you more control over the apps and information allowed to pass through than a VPN would.
Is SSH over the internet secure?
Yes. SSH offers additional security, and sending data over SSH will always be safer than doing it with no additional security.
