VPN vs SSH – What’s the Difference ? (Pros and Cons). In this article we talk through two systems that create secure tunnel for data travel. Firstly, both of these tools are extremely useful in protecting the privacy and security of our data online. Hence, this article compares VPN and SSH to help you to decide better suited tool for your requirements.
Nowadays, with most of our activities taking place over the internet, securing your privacy and personal information has become crucial. In order to protect your information, it is advisable to use various tools such as VPNs and SSH. But do you want to protect data just at the application level (SSH), or with VPN that also encrypts and protects all your data on the network?
Let’s find out which tool is better suited and start the article blog VPN vs SSH – What’s the Difference ? (Pros and Cons).
What is VPN?
First of all, VPN (Virtual Private Network) is the easiest and most effective way for people to protect their internet traffic and keep their identities private online. What VPN does, it encrypts your data traffic and sends it through a remote server. After that it changes your IP location. All in all, it protects your online privacy, ensuring that nobody intercepts your traffic, looks at your data, or see your geolocation. Additionally, it protects you, when using public WiFi networks.
Pros of VPN
- Enables a secure connection to the internet, as it encrypts the data being transmitted. As a result, VPN users are assured that their information is protected from third parties such as hackers, ISPs or governments.
- Allows users to maintain their online privacy by hiding their IP address and allowing them to use the internet anonymously. No fear of being tracked or monitored by advertisers or other unwanted parties.
- Helps to save money by reducing phone or internet bills. Additionally VPN users choose servers from different countries, avoiding costs associated with roaming or blocking services in other countries.
- Works as a handy protction tool for activists in hostile environments.
- Protects your online privacy.
Cons of VPN
- Cheap or free VPNs are slow, insecure and may collect your data.
- Incompatible with certain devices.
- Not all VPN services are equally secure. Some VPN services may collect user data or contain security holes, which could compromise your privacy.
What is SSH?
Pros of SSH
- Much easier to set up on a server level.
Cons of SSH

VPN vs SSH -Differences Comparison
Contrarily, SSH is usually available as open source software and used without any licensing costs. However, using commercial SSH solutions, they are ideally better for larger organisations. Important to note, the cost ranges from a few dollars to tens of dollars per month, also depending on the number of users and security requirements.
Encryption is a strong point. With network traffic VPN ensures, that all network traffic between the VPN client and the VPN server is encrypted. So, all network traffic, including data sent between the client and the destination server, is encrypted and transmitted through the VPN tunnel. So VPN solutions are ideal for gaining secure remote access to the entire network.
On the other hand, SSH only allows secure remote command execution and device management, not the transfer of all network traffic. Additional advantage of SSH is that it encrypts the data transmitted between the client and the server, but only that, which is required to execute SSH commands. All in all, that contributes to the fact that network traffic other than SSH data (e.g. web browsing) is not encrypted and is not sent through the SSH tunnel.
Importantly with VPN solutions is that, they are typically scalable and easily adapted to the changing needs of an organisation. Different variants of VPN solutions are available, such as enterprise VPN, multi branch VPN or remote worker VPN. In turn, that allows the solution to be tailored to the specific requirements of the organisation. Besides, VPN support multiple users and are typically available in different variants, such as a VPN private network (VPN LAN) or a client server VPN.
The scalability of SSH is typically less than that of VPN solutions. With SSH, it is geared more towards remote command execution and device management, rather than providing security for the entire network. Whilst there are methods to scale SSH solutions, such as using SSH clusters, these solutions are less flexible and than VPN solutions.
The solutions that SSH offers have been mainly designed for secure remote management of servers and devices such as routers, switches and servers. And on top of this, SSH allows remote command execution, file transfer and device configuration management. Furthermore, it is particularly useful for system administrators and network engineers who often work remotely.
Security of VPN is at a high level. By encrypting all data traffic between the remote user and the VPN server various encryption protocols are used, such as SSL, TLS, and IPsec. Further, this ensures that data cannot be intercepted or tampered with. Moreover VPNs also provide secure authentication and access control mechanisms, ensuring that only authorized users access the network.
Balanced against, SSH also provides strong encryption and authentication mechanisms, but it is primarily designed to protect against eavesdropping and tampering during communication with a remote server. Following, SSH uses public key cryptography to authenticate users and encrypt data in transit. Furthermore, it also provides protection against various types of attacks such as password cracking, brute force attacks, and man in the middle attacks.

VPN vs SSH – What’s the Difference ? Conclusion
In conclusion, both VPN and SSH are powerful tools for securing remote access to network resources. VPN is best suited for connecting to a private network from a remote location and provides robust security features to protect against attacks targeting the entire network. On the other hand, SSH is much easier to set up on the server level. An excellent option for securely accessing a single remote computer and provides strong encryption and authentication mechanisms to protect against eavesdropping and tampering.
The most notable difference is encryption. Vpn does it all by encrypting all data coming to and from a device and it is so simple to use for any level user. Protecting your data is much easier with a VPN as a whole.
Whereas SSH you have to configure each application to use an SSH tunnel and it is difficult to set up.
Ultimately, the choice between VPN and SSH depends on the specific needs of the user. It is important to consider factors such as security requirements, ease of use, and configuration complexity when selecting the appropriate technology for secure remote access.
