Virtual Private Dial-Up Network

(also VPDN)

Virtual private dial-up network definition

A virtual private dial-up network (VPDN) is a way for remote users to securely connect to a company's private network over the internet. Think of it as a secure, virtual version of old dial-up connections, allowing employees to access their work network from anywhere, just like in the office.

How does a virtual private dial-up network work? 

  1. 1.A remote user uses their computer to dial into their internet service provider (ISP) using a modem, just like old-school internet connections.
  2. 2.Once connected to the ISP, the VPDN creates a secure tunnel over the internet to the company’s private network.
  3. 3.The user logs in with a username and password to verify their identity.
  4. 4.After logging in, the user can access the company’s private network, files, and applications as if they were in the office.

What are the main benefits of using a VPDN?

  • Employees can securely connect to the company network from anywhere.
  • Uses existing internet — you won’t need extra equipment.
  • Keeps data safe while being transmitted.
  • Works with different devices and platforms.
  • IT can easily manage and secure remote connections.


  • Both VPDN and VPN create a secure, encrypted tunnel for data transmission.
  • Both allow users to access a private network from remote locations.
  • Both help protect user data and privacy while online.
  • However, VPDN often uses dial-up connections — while VPNs typically use broadband or other high-speed internet connections.
  • VPDNs were more common with older dial-up technologies, whereas VPNs are widely used today with modern internet connections.
