VDI vs. VPN: Which is best for remote workers?

What is VDI?

VDI stands for virtual desktop infrastructure. It is a virtual network computing system in which desktop environments are hosted on remote servers and transmitted to end clients over the network. The clients can then access the desktop environment using specific applications and customize it.

VDI servers usually reside on either the premises of an organization or the cloud online. While each remote device in a VDI system can function independently, they can all be managed and updated from a centralized control point.

The term VDI usually refers to a specific Windows-based remote desktop system but is sometimes also applied to the general concept. Separate virtual machines with their dedicated resources improve its overall security. So all users have their dedicated stations, and this improves customization and performance capabilities.

Imagine you manage an office, and you need to use multiple desktop PCs for your employees. If each employee's desktop has specific security configurations, you have to be able to upgrade them constantly. But with VDI, you can transfer all these tasks into a virtual sphere and control the processes remotely.

Pros

The main advantages of VDI systems are centralized management and security. Here's how that makes life easier for both companies and users: 

• Centralized system management is an efficient way to get tasks done. An admin can easily implement updates and fix issues because they have centralized access. Also, multiple devices can be updated at once.
• The admin side has more control. Companies have more control over the whole system and can be sure that everyone is connected. This is because the infrastructure is usually on the company's server side. Also, it relies less on the performance of users' devices.
• It's fast because each user has dedicated resources. Each user has their own dedicated system, which can be customized according to their needs. Such adjustability makes for quicker performance.

Cons

If you're considering using VDI, it's also good to know the downsides.

• It’s expensive. VDI systems will always be more expensive than a VPN because they require extensive components and more complex maintenance.
• It’s complicated to implement and maintain. VDI setups require numerous components, complicated installation processes, and multiple machines. They're also more difficult to update from the server side.
• They rely on a third-party. You still rely on a third party because the VDI company maintains all the infrastructure, so users never have 100% privacy.

What is a VPN?

A virtual private network, or VPN, is another option worth considering for remote work. A VPN service encrypts users' traffic and masks their IPs by routing their data through a remote server. It's a simple and hassle-free way to enhance privacy and protect your data from prying eyes. You just need to download an app to your device and connect to a VPN server.

But if this technology only encrypts one device, why do you need a VPN in an office environment? Well, you can actually configure your office router to use a VPN so that every device connected to it is protected. You can also use a VPN to encrypt traffic within your company's network. With multiple employees using the VPN, everyone on a team can securely access private folders, and the risk of endpoint breaches is significantly lowered.

Pros

Besides online privacy and security, VPN benefits include:

• Relatively cheap. VPNs are a cheaper solution than VDI systems, and with a configured router, multiple devices can be covered through a single VPN account.
• Easy to implement and use. A VPN doesn't require extensive infrastructure within a company, so it is much easier for an organization to implement fixes and updates.
• Easily accessible for users. Employees can enjoy a simple user experience, establishing a secure connection with the click of a button.
• Fast internet speeds. Thanks to large, well-maintained server networks, most premium VPN services offer high speeds.
• Extra features. VPNs usually include many extra features. NordVPN, for example, offers an ad blocker, a kill switch, and other important and useful features.

Cons

To gain some perspective, let's look at the downsides of a VPN.

• A decentralized approach. If you ask employees to install VPN software on their devices, you're relying on them to use the service correctly and to remember to switch it on. Some businesses may not want to put that much responsibility on individual employees.
• User devices can impact performance. As with any software, VPN applications run differently on different devices. If some employees use older hardware with outdated operating systems, VPN performance may suffer.
• Free VPNs are unreliable. Some free VPNs are unsafe and may collect or even leak your data. That's why you must always use a reliable, premium VPN provider.

Difference between VDI and VPN services

To better understand the distinction between the services that a VDI and a VPN offer, check out the table below:

Is VDI better than a VPN?

No, a VDI system is not better than a VPN in most situations. From a user perspective, we definitely recommend a VPN as an easy-to-use and essential tool for online safety.

VDI is an excellent B2B solution, which could be more suited to large businesses. But for smaller enterprises, VPN is probably a better and more sustainable option. It costs less, and it’s much easier to implement. Check out our NordLayer product for a high-quality B2B security solution.
