Why VPN for 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.
Rely on trust
As a leading German manufacturer of network solutions for business customers, we have been successfully implementing secure, reliable, and future-proof infrastructure solutions "Made in Germany" – 100% backdoor-free – for more than 20 years.
Thousands of satisfied customers trust in our network solutions, our know-how, and our deep understanding of the requirements of medium-sized businesses.
In our Online Masterclass Site Networking, we demonstrate in 30-minute webinars how companies can network their sites in a secure and future-proof way.
However, the practical experiences of other international companies are particularly interesting. With 500 locations in 21 countries, the Dussmann Group is a leading multi-service provider in the fields of facility management, food services, and technical solutions and has transformed its IT infrastructure into a more uniform, secure, and user-friendly one with LANCOM. Our video takes you through the project and reveals the reasons, challenges, and benefits of the rollout with LANCOM.

VPN – 5 key advantages
Find out why exactly you should choose a VPN solution for your IT project – and why we make the difference as your partner.
1. VPN is trustworthy
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.
The German Federal Office for Information Security (BSI) recommends VPN according to the IPsec-IKEv2 standard
In its Technical Guideline (TR) BSI TR-02102-3 of February 11, 2022 on the subject of "Cryptographic Procedures," the German Federal Office for Information Security recommends version 2 of the IKE protocol (IKEv2) when using IPsec VPN applications. LANCOM Systems follows this recommendation and relies exclusively on this standard for all VPN components, as well as other state-of-the-art security functions such as elliptic curves and AES-GCM for IPv4 and IPv6 – and thus on maximum protection for your data.
2. VPN is flexible
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, network structures of any size can be implemented securely and flexibly.
One portfolio for all connections
LANCOM offers the most comprehensive VPN portfolio on the market with interfaces for fiber optics, xDSL, Gigabit Ethernet, Supervectoring, LTE, LTE-Advanced, and 5G. This allows you to network small, medium-sized, and large enterprises independently of the Internet lines available at the site-using state-of-the-art VPN technology.
3. VPN goes easy on your resources
With a professional and easy-to-use VPN solution, the secure networking of 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!
VPN champion for the sixth time in a row
For the sixth time in a row, LANCOM Systems is awarded the title of champion in the Virtual Private Network (VPN) solution area in the 2022 "Professional User Rating Security Solutions (PUR-S)" user survey conducted by the analyst firm techconsult. Top marks were awarded for the performance of the VPN routers, gateways, firewalls, and clients and their range of functions. Users also gave LANCOM top marks in the category "Solution benefits" when it came to "Reducing damage from security incidents", "Working more efficiently with secure solutions", and "Reducing the workload of the IT department". In the vendor evaluation, LANCOM achieves the best rating of all the vendors evaluated in the categories "Sales partners," "Price and purchasing models," and "Service and support," among others.
4. VPN is scalable
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.
The core of secure growth
LANCOM VPN routers "grow" with your requirements: Simply upgrade them with additional VPN tunnels via a cost-effective software option! And the high-performance LANCOM central site VPN gateways form the core of any larger VPN networking strategy, because they implement cross-site multi-service IP network structures centrally, securely, with high performance, and with maximum reliability. If required, our "Integrated Services Gateways" can be easily expanded to include additional functions such as hotspot, clustering, or up to 3,000 VPN channels.
5. VPN is reliable
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.
LANCOM HSVPN and active/active connections
Rely on the market-leading technology LANCOM High Scalability VPN (HSVPN): Significantly fewer VPN tunnels are required and recovery times in the event of a failover are significantly reduced. Thanks to the integrated load balancer, VPN connections can be conveniently combined into an active/active solution. Whether in combination with a LANCOM router, central site VPN gateway, or the innovative LANCOM vRouter: In addition to improved load balancing and takeover of data traffic if a connection fails, the VPN bandwidth for multiple clients is significantly increased by the aggregation.
Compared to VPN for secure and trusted access to networks, ZTNA technology is based on an application-oriented approach. In other words, dedicated and encrypted connections to specific applications are negotiated rather than network access. Based on the zero-trust model, all devices and users are initially distrusted before accessing network applications so that access is denied. Only after verification and authentication are users or devices granted access to applications explicitly permitted or assigned to them.
This approach allows detailed micro-segmentation of applications and users in the network. It can also be used, for example, to ensure that certain departments only have access to applications that are relevant to their work.
