What Is a VPN Concentrator

In this piece, we are going to figure out what a VPN concentrator is and what it is used for. Keep reading to check this out!

Detailed VPN Concentrator Review

A VPN concentrator is a networking device that allows the establishment and management of multiple virtual tunnels at the same time and provides an encrypted connection between different VPN nodes. As we are on the same page, a virtual tunnel is a secure connection that uses advanced encryption technologies to protect all your data and online traffic.

In other words, a VPN concentrator extends the capabilities of a VPN router. This networking device can serve thousands of users at the same time and create a virtual tunnel for each of them. As a result, if an organization or business uses a VPN concentrator, its employees can securely connect to the company’s network from anywhere in the world.

VPN concentrator working principle

A VPN concentrator does a similar job to Virtual Private Network solutions: it encrypts both the outgoing and incoming internet traffic, implements security protocols to create impenetrable tunnels, conceals an actual IP address with a virtual one, and whatnot.

How does a VPN concentrator work:

  • This solution created multiple encrypted tunnels in a single network to reliably protect internet traffic.
  • It confirms the authentication of users who have access to the centralized system.
  • Also, this networking device scrambles online traffic and ensures end-to-end encryption.
  • Virtual Private Network concentrator masks a user’s actual IP address and assigns a virtual one.

What Is a VPN Concentrator Used For

Despite the top-notch privacy provided by VPN concentrators, individuals rarely use these networking devices. VPN concentrators are mostly implemented in large enterprises with many remote employees. Using such technology helps companies ensure the same level of protection for all their employees.


VPN Concentrator vs VPN Server

VPN concentrators operate at the network’s forefront, usually next to or beneath a firewall. This hardware device comes equipped with dedicated software that determines the number of available VPN connections. The concentrator works similarly to a VPN, but on a larger scale. It also encrypts data and web traffic. In addition, the concentrator tunnels data using security protocols. 

The major difference between a VPN concentrator vs VPN server is that the former is rarely used in private settings. You’re more likely to see them implemented in large corporate networks with numerous remote employees. It’s also often adopted by organizations where a secure remote connection is vital, such as the military.


VPN Concentrator vs VPN router

So then, what’s the difference between a VPN router capable of tunneling and a VPN concentrator? The answer actually depends on what type of router we’re talking about, as they vary in terms of the kind of remote access you get, certain underlying features, and what apps you will be using.

Generally speaking, for an SMB a VPN router will be preferable, in most cases. This way you will set your organization to benefit from extra security while significantly reducing the cost. But if you work for a medium-to-large corporation, need an industrial solution, and aren’t concerned with the cost, then a VPN concentrator might be a good option.
