What is a vpn concentrator

The increasing prevalence of remote work makes the companies look for advanced ways to ensure their operations’ security. Businesses need to provide the employees’ home devices with the same protection level as corporate technology has. An effective way to achieve this goal is the use of VPN concentrators. This article will help you better understand what this technology is and how it can help your business.

What is a VPN concentrator?

A VPN concentrator is a device designed specifically for creating and managing VPN communication infrastructures. It provides the secure VPN connections between a set of nodes. At its core, it is similar to a router with enhanced security and power that handles a large number of remote connections through VPN tunnels. A VPN concentrator integrates a set of devices into one network protected from external intrusion and tracking.

What does a VPN Concentrator do?

A VPN concentrator ensures the safety of connections and their transition across the potentially dangerous networks without the risk of data’s abduction. Each of the VPN tunnels functions independently, which provides the users with freedom within the network while protecting their privacy and safety. Therefore, a concentrator creates a secure multi-user environment within a single VPN network.

When considered in more detail, the functions of a VPN concentrator may be defined as follows:

  • Creation of multiple VPN tunnels within a single network.
  • Authentication and authorization of users.
  • Assigning IP addresses to the network’s users.
  • Encryption and decryption of data.
  • Providing end-to-end encryption of data moving between remote clients and a centralized network.

Who uses it

The primary users of VPN concentrators are organizations operating multiple systems connected through various networks. What can these devices bring to such companies? The essential features that make them useful for businesses include increased security and support for multiple users. Through them, VPN concentrators provide employees with safe and convenient access to the Internet anywhere, making them especially relevant for companies whose employees work remotely. When network users enter them through remote access software, there is always a chance of external attacks. VPN concentrators ensure that the company’s local network remains protected from external threats and that the secure tunnels transmit only encrypted data. Given the above characteristics, VPN concentrators may be most useful for companies whose employees work within a single network, especially when it comes to remote access to workplaces.

VPN Concentrator vs VPN router

VPN concentrators are often confused with VPN routers. However, despite some similar features, these are different devices. A VPN router is a piece of hardware with VPN pre-installed directly on them. As a result, all devices that connect to these routers immediately connect to the protected VPN network. Routers are a more convenient and reliable alternative for installing VPN clients on each device separately.

What primarily makes VPN concentrators different from routers is the magnitude of their power. Concentrators can support thousands of VPN clients by uniting them into a single integrated network. They also serve as connection points for remote devices that do not have to be within the router’s physical reach. Not to say that the concentrators have higher security levels and apply additional measures to ensure the most effective data encryption.

Thus, although their general purpose is similar, a VPN router and a VPN concentrator operate on different principles. As a result, the former is suitable for use at home and in small businesses, while the latter is perfect for large-scale organizations with many remote workers.

The most popular VPN concentrators

As in the case of VPN providers, the VPN concentrators market is characterized by numerous competing players. The functional value (and, consequently, the price category) of concentrators depends on their working capacity and the number of tunnels they are able to support. Today, the following brands are the most popular in this technology niche:

  • Cisco Meraki
  • ShoreTel
  • Aruba
