VPN concentrators operate within a firewall, parallel to the firewall, or both. Their functions are similar to traditional VPNs, but they differ by design and in how many connections they support. VPN concentrators sprout dozens of VPN tunnels, assign unique IP addresses to each client, and perform authentication to prevent unauthorized access. VPN concentrators also execute end-to-end delivery circles, which protect network traffic.
Creating a secure network ecosystem with a VPN concentrator
A VPN concentrator allows you to extend the capabilities of your VPN router to provide secure connections for multiple remote users. A VPN concentrator creates a VPN tunnel for each user to access your company’s network from anywhere in the world. Usually, it stands underneath your company’s firewall. A VPN concentrator encrypts data, both incoming and outgoing, and extends the company’s security perimeter to remote computers.

This is an especially good solution for growing businesses as it avoids the hassle of configuring and maintaining multiple routers and VPN clients. Moreover, it can connect thousands of users to a central network without sacrificing performance. Therefore, it is the perfect solution for a company with multiple branches and multiple locations.
Functions of a VPN concentrator
What is a VPN concentrator? A VPN concentrator is a computer that allows users to connect to one network from another, either via the Internet or a phone line. These devices are useful for large organizations that coordinate network operations and need to ensure that all users can connect to one network. They provide data encryption and authentication for multiple users and create separate tunnels for each user. They also enable remote workers to access network files while remaining on the same network.
The VPN concentrator enables advanced security features, such as policy-based access control, which limits the amount of time end-users are allowed to use certain resources. Administrators can assign different policies to individual users using this feature. The administrator can also limit VPN access to a specific VPN client and tunnel. This way, all users can securely access their network and avoid exposing sensitive information to unauthorized users. These security features are a must-have for any large organization.
Security provided by a VPN concentrator
A VPN concentrator is a piece of network equipment that allows a company to simultaneously supply protected VPN tunnels to large numbers of users.

This equipment implements a number of security protocols to ensure end-to-end encryption and protect your network from unwanted third-party intrusions. Moreover, a VPN concentrator masks the user’s IP address and assigns them a virtual one. This gives you the peace of mind that your private data and online activities are secure.
Cost of a VPN concentrator
The cost of a VPN concentrator depends on the type and size of the company. The more advanced the concentrator, the more expensive it will be. Some concentrators support ten thousand clients, while others support only a handful. VPN concentrators with IPsec capabilities are generally more secure and provide the widest range of options. However, an SSL-VPN concentrator is much easier to install and configure than an IPsec-based concentrator.
