VPN site networking

Virtual private networks (VPNs) are the most economical solution for securely encrypting the networking of multiple locations, even those that are very far apart. The trick: VPNs use the public medium of the Internet as a communication path and secure the connection in such a way that communication nevertheless remains completely inaccessible to external parties. With a secure VPN connection, companies can connect their branches, subsidiaries, and mobile employees to the internal network.

A VPN is a "secure data tunnel" through one of the most insecure media ever created by man: the Internet. Basically, a VPN is a private, virtual network based on IP, in which only users who belong to this network can exchange information and data. For the users, it appears as if they are in a shared network – just as if they were sitting together in the office. In such a VPN network, the authenticity, confidentiality, and integrity of all exchanged data are ensured, so that a trustworthy working environment is guaranteed. As a cloud-managed VPN, this remote access concept can be managed centrally and effortlessly and, in the case of the LANCOM Trusted Access Client, can also be developed into an access model based on the zero-trust principle if required.

Smooth, location-independent communication is essential for efficient and economical operation and thus a decisive factor for your success. However, each company location has its own individual requirements, such as the existing Internet lines. In order to take this individuality into account, a solution is therefore required for the precise, flexible and, above all, secure design of the network – across locations, powerful, and protected against access by unauthorized parties. With VPN-capable devices from LANCOM, company networks of any size can be implemented securely and flexibly.

With a professional and easy-to-use VPN solution, the secure networking of two or more locations is not a massive task: branches, branch offices, home offices or service providers and cooperation partners are securely connected to the corporate network without rigid and outdated MPLS lines and without complex detailed configurations. Authorizations can be assigned on a fixed basis via virtual networks, so that access is only granted to corporate data relevant to the task in hand. With this economically efficient solution, several securely isolated networks can be set up in parallel using just one infrastructure. At the same time, this massively saves on investment, configuration, and maintenance costs!

Techpaper: Advanced Mesh VPN

Whether it's a smaller agency with a few home offices or a multinational branch structure with high data volumes and many digital applications: A VPN solution is the right choice for networking companies of all sizes. IPsec VPN is a standard that ensures full interoperability of all components chosen according to the purpose and size of the site. Even new locations or external employees are integrated into the corporate network in no time at all. Thus, with a professional VPN infrastructure, you have the best hand and bet everything on future viability, scalability, and growth.

A cut Internet line is enough to bring the entire network and thus the entire work to a standstill. It's good to have professional equipment with backup functions! Here, several types of Internet connections available at the respective location, such as DSL, fiber optics or even mobile communications (5G / 4G), are used. Thus, the 5G line takes over the task as a backup of the primary Internet access in the event of a failure of the wired line, so that VPN connections are also maintained with high availability and no Internet failure is noticeable at the site. For more total bandwidth, professional routers with multiple WAN modems can also use several Internet lines in parallel: Active/active load balancing groups distribute data connections evenly over at least two lines and add up the individual bandwidths of the lines.
