How to Set Up a VPN Connection for Work

What is a VPN and why do you use it for work?

A VPN (Virtual Private Network) creates a secure, encrypted connection between your computer and the company network. When you work from home, a VPN is often necessary to access company systems, files and applications securely. In this article we explain how to set up and use a VPN connection for work.

Why is a VPN important when working from home?

Working from home comes with security risks. Your home network is less secure than the office network, and you send sensitive company data over the internet. A VPN solves these problems.

Data security

A VPN encrypts all data traffic between your computer and the company network. This means that even if someone were to intercept your connection, they cannot read the data. This is crucial when you work with confidential information.

Access to internal systems

Many company systems are only accessible from the internal network. With a VPN you get an IP address from the company network, so these systems think you are at the office. That way you can work as if you were physically present.

Compliance and regulations

For many organizations, using a VPN when working from home is mandatory because of data protection laws and regulations. Think of the AVG/GDPR or industry-specific security requirements.

Getting the VPN software

The first step is getting the right VPN software and login details. This differs per organization.

Through your employer

Contact your IT department or system administrator. They can provide you with the software, configuration files and login details you need. You often receive an installation link, or the software is distributed automatically if your laptop is managed by the company.

Common VPN solutions

There are several VPN solutions that companies use:

• Cisco AnyConnect: Widely used by large organizations
• OpenVPN: Open source solution, popular with smaller companies
• Pulse Secure: Enterprise VPN with extensive features
• GlobalProtect: VPN client from Palo Alto Networks
• Windows built-in VPN: For simple configurations

Installing a VPN in Windows

Once you have the software, you can install and configure the VPN.

Installing the VPN client

Download the VPN software from the location your employer has specified. Run the installation file and follow the instructions on the screen. This is usually a standard installation where you accept the terms and choose an installation location.

Importing the configuration

Some VPN clients require a configuration file. This file contains the server addresses and security settings. Import this file through the settings of your VPN client. Your IT department can tell you exactly how this works for your specific solution.

Built-in Windows VPN

Windows also has a built-in VPN client. To use it:

1. Go to Settings, Network & internet, VPN
2. Click Add a VPN connection
3. Enter the details you received from your employer
4. Save the connection

Connecting to the VPN

Now that the software is installed, you can connect to the company network.

Starting the connection

Open your VPN client and click Connect. You are asked to enter your username and password. These are usually your normal company login details, but this can differ per organization.

Two-factor authentication

Many companies use two-factor authentication (2FA) for extra security. After entering your password, you need to enter a code that you receive through an authenticator app, SMS or token. Make sure you have set up this method before you try to connect.

Checking the connection status

After connecting successfully, you see a confirmation in the VPN client. An icon often also appears in your system tray to show that the VPN is active. You can now work securely as if you were at the office.

Troubleshooting

VPN connections can sometimes be tricky. Here are solutions for common problems.

Connection fails

If the connection cannot be established:

• Check your internet connection by opening a website
• Check that you are using the correct server and port
• Temporarily turn off your firewall or antivirus program to test
• Try restarting your router
• Contact IT if the problem persists

Slow connection

A VPN can affect your internet speed because all traffic is rerouted and encrypted. If the connection is too slow:

• Try another VPN server if that option is available
• Close unnecessary programs that use bandwidth
• Check whether your home internet is fast enough
• Ask your IT department whether split tunneling is possible

Connection drops regularly

If your VPN connection keeps dropping:

• Check the stability of your Wi-Fi connection
• Try a wired connection via Ethernet
• Check the settings for automatically reconnecting
• Update your VPN client to the latest version

VPN etiquette and best practices

Using a company VPN comes with responsibilities.

Business use only

Use the VPN connection only for work-related activities. All your internet traffic runs through the company network, which means your employer can see which websites you visit. Keep personal matters separate from your work connection.

Disconnect when you are done

Disconnect the VPN when you are done working. This saves bandwidth on the company network and prevents you from accidentally sending personal traffic over the work connection.

Keep software up to date

Install updates for your VPN client as soon as they are available. Updates often contain important security improvements. Don't ignore update notifications.

Don't share login details

Never share your VPN login details with others, not even with colleagues. Every user should have their own account for traceability and security.

VPN on mobile devices

You can also set up a VPN on your smartphone or tablet for working on the go.

iOS and Android

Most business VPN solutions have apps for iOS and Android. Download the app from the App Store or Play Store and log in with your company credentials. The configuration often happens automatically after you log in.

Working on the go with a VPN

Keep in mind that VPN connections use extra data and drain your battery faster. Only connect when needed and disconnect when you are done working.

Alternatives to a VPN

Although a VPN is the standard, there are also other solutions for working securely from home.

Zero Trust Network Access

Some modern organizations are switching to ZTNA (Zero Trust Network Access). This gives access to specific applications instead of the entire network, which can be more secure.

Cloud-based workplaces

If your organization works fully in the cloud (Microsoft 365, Google Workspace), a VPN may not be necessary. The security is then built into the cloud applications themselves.

Conclusion

For many people who work from home, a VPN connection is essential to access company systems securely. By installing the right software, configuring it correctly and following the best practices, you can work from home productively and securely. If you run into problems, your IT department is always the best source of help, because they know exactly how your specific VPN environment works.

Frequently asked questions

How do I get access to my employer's VPN?

Contact your IT department or helpdesk. They can provide you with the VPN software, configuration files and login details you need. You often get an installation link by email, or the software is installed automatically on your work laptop.

Why is my internet slow when I use the VPN?

A VPN reroutes all your internet traffic through your employer's servers and encrypts all data. This takes extra time and bandwidth. Ask your IT department whether split tunneling is possible, so only work traffic goes through the VPN. Also make sure you have a stable internet connection at home.

Can I use the company VPN for personal browsing?

That is strongly discouraged. All your internet traffic through the company VPN can be monitored by your employer. Use the VPN only for work-related activities and disconnect when you are done working. Keep personal and work use separate.

What should I do if the VPN connection doesn't work?

First check your internet connection. Then check that you are using the correct login details and server. Restart the VPN client and try again. If the problem persists, contact your IT helpdesk. They can see whether there are problems on the server side and help you further.
