SD-WAN: Modern site networking with maximum flexibility
Your company is growing, new locations are being added, and suddenly you have a patchwork of expensive MPLS lines and sluggish VPNs. Data traffic is stalling, costs are rising, and flexible adjustments? Not a chance. Sounds familiar? Then SD-WAN is the solution.
SD-WAN (Software-Defined Wide Area Networking) offers an intelligent way to network locations flexibly. Instead of relying on single, expensive lines, SD-WAN combines different internet connections and optimizes data flow. This keeps business-critical applications available, costs under control, and your network future-proof.
What is SD-WAN?
It is not a fixed product with set standards, but rather a flexible approach to connecting company locations. While it is based on VPN technologies, it goes far beyond that. Companies can:
Intelligently control data streams. SD-WAN automatically selects the best connection.
combine multiple internet lines – such as DSL, fiber optic, or LTE.
centrally manage networks: with less effort and more control.
SD-WAN is the key to smart site networking and optimized connection of cloud services. Thanks to zero-touch configuration, the technology can be implemented without much effort – and replaces conventional MPLS-based connections with a more flexible, cloud-capable solution.
The advantages of SD-WAN
-
Automated Setup
Locations can be integrated in just a few minutes, even without specialized technicians on site.
-
Intelligent Traffic Management
Business-critical applications always have priority, less important data streams are intelligently distributed.
-
High availability
SD-WAN uses multi-link strategies and can utilize multiple parallel connections (e.g., DSL, LTE, fiber) in such a way that it automatically switches in case of disruptions.
-
Cloud Integration
Cloud services such as Microsoft 365 run directly without detours through central data centers. This saves bandwidth and reduces latency.
-
Safety included
Integrated encryption and segmentation protect enterprise data.
-
Cost efficiency
MPLS lines can be replaced by cheaper alternatives.
-
Automated Management
Central administration for less administrative effort and more transparency.
Not every SD-WAN is the same - what makes CMS different
Many providers sell products under the name SD-WAN that are ultimately nothing more than improved VPNs. CMS takes a different approach. We rely on an SD-WAN architecture with Extreme Networks' fabric technology.
This technology enables Layer 2 services across WAN distances - a major advantage for sensitive IT environments, such as in hospitals or industry. Companies benefit from maximum security, minimal administrative effort, and maximum stability.
Savings potential and architectural decisions with SD-WAN
Fabric services across geographically distributed locations
Many companies face the question: Decentralized firewalls for each location or a central security strategy? SD-WAN offers an alternative that centralizes network security and routing without losing flexibility. Instead of equipping each location with expensive firewalls, companies can save thousands of euros per year with an SD-WAN-based security solution - while achieving higher efficiency.

FAQ
-
What is SD-WAN and why is it important?
SD-WAN is an intelligent networking solution for enterprise locations. It can combine different internet connections, optimize data traffic, and enables centralized management.
-
What advantages does SD-WAN offer compared to traditional site networking?
SD-WAN is more flexible and cost-effective. It uses cost-efficient internet connections and ensures better control of data traffic, lower latencies, and easier management.
-
How does SD-WAN improve the reliability of an enterprise network?
SD-WAN manages multiple internet connections in parallel. If one line fails, the system automatically switches to another - without causing outages or noticeable disruptions for users.
-
What security mechanisms does SD-WAN offer?
SD-WAN integrates encryption, segmentation and central control of data traffic. This provides better protection for corporate data, even when using public internet connections.
-
Should SD-WAN be combined with a firewall?
Yes. Although SD-WAN provides basic security functions, it is recommended to use a perimeter firewall for additional protection - especially for branch offices with direct internet access (Local Breakout).
-
How does zero-touch deployment work with SD-WAN?
With zero-touch deployment, new locations can be integrated in just a few minutes. The hardware is simply connected and automatically connects to the central management system - without manual configuration on-site.
