Remote access VPN is of utmost importance for organizations that offer their employees work-from-home opportunities. The Coronavirus pandemic has also stressed the need for remote work in almost every organization around the globe.

Therefore, it is essential to take extra precautions while handling the corporate files and crucial information. Visit here to learn how NordLayer provides an extra layer of security for you and your work-from-home setup in this scenario.

What is remote access VPN?

Remote access VPN is just like other VPNs, but it allows users to remotely access the data and files of their organizations. It helps people use and access the required files from the company's data center, cloud locations, and main offices by giving encryption.

The encryption method in this tool plays a significant role in the secured communication of the data between remote destinations. It scrambles the data while passing through the tunnel and makes sure no rogue actor comes near it.

It establishes a secure connection between two sources: the sender (user) and the receiver (data center). Having such a data security tool will help the employees to work safely and without mental stress.

How does remote access VPN work?

Now that we understand the existence of remote access VPN let's look at its working procedures. Remote access VPN works by creating a secure tunnel between the two sources; sender and receiver.

The secured tunnel acts as an encrypted gateway between the organization's network and the employee's device. Although the gateway goes through the public internet, the VPN ensures that data reaches the other side without compromising.

The two main elements in the remote access VPN are the client software and the Network Access Server, also known as a NAS. A network access server could be a software application or a dedicated server. You can connect to the network access server over the internet to use the VPN.

Before using the VPN, you need to sign in because NAS should provide valid information. NAS runs its authentication procedures or a different method on the same network to check the client's information.

Once the gateway creates a connection, you can use it for secure communication. When you send the encrypted data from your remote device and pass through a remote tunnel, it gets decrypted and then shared with the protected servers.

Before using remote access VPN, you also need to install a software application on your device. It is essential to establish and sustain a stable connection to the application. Nowadays, most prepare built-in software that can easily connect to the VPN. The downloaded software application helps create a gateway to the NAS and administers the security to keep the connection encrypted and safe.

Why do you need remote access VPN?

Remote access VPN is a crucial tool that has changed how organizations view security solutions. Companies can allow their employees to work remotely to carry out the required tasks in an encrypted environment by having this tool.

Using a remote access VPN has numerous benefits, which would make you use it either for personal or business-related matters. The first advantage of this tool is data security. It is crucial for those employees who work remotely.

So, when they send the data through the VPN tunnel, hackers or other rogue actors would not harm the data. The first benefit is also vital for such conditions when the employees try to access the corporate data center through public Wi-Fi. Using a public internet is risky as they are not usually encrypted.

The second benefit of using remote-access VPNs is their affordability. Companies can find an affordable way to secure their data sent by virtual employees. The initial investment to launch and set up a VPN is low, so you can quickly grow the application.

The third benefit of the remote access VPN is its seamless experience for users, especially businesses. Companies can deploy this network in a minimum time, which would provide instant access to all the applications and also enable you to organize permissions for the critical resources when using the files in an open connection.

The fourth benefit that would make you download this VPN is its smooth access option for the business resources. Due to its dedicated server, you can create customized gateways for the business team members and ensure secure and convenient access to the critical resources irrespective of the physical environment.

The fifth benefit of this virtual private network is its ability to boost productivity. It can help employees work better and faster through collaboration and secure connections. This private network can be a blessing for organizations worried about their sensitive assets and want to increase employee productivity.


Remote access VPN is a powerful tool for people and companies to secure their crucial data and assets while offering remote access to other people. It allows users to send the data through an encrypted gateway, preventing hackers from using malicious attacks to steal the information. The VPN establishes a secure communication channel between a sender and a receiver to exchange data safely.

Remote access VPN offers its users multiple benefits, such as seamless experience, cost-effectiveness, data security, smooth exchange of information, increased productivity, and discouraging illicit activities.
