Secure SD-WAN Wins Over MPLS

Secure SD-WAN Wins Over MPLS

When comparing the SD-WAN and the MPLS in terms of cost, security, and performance, SD-WAN seems to be the winner.

FREMONT, CA: One of the significant questions network security architects ask as they consider their WAN architecture is, Should they choose SD-WAN over MPLS? The decision to switch to SD-WAN has considerable implications for businesses. But the problem is that most SD-WAN solutions don’t offer the same security level as MPLS, in which a secured tunnel is running through a Service Provider’s network. Expert recognizes some considerations to consider in choosing an SD-WAN solution to provide a more effective strategy over MPLS. Here is why SD-WAN is a better choice for businesses.

Compared to MPLS, SD-WAN can be less expensive, more secure, and offer higher performance. MPLS can have steep bandwidth costs, while SD-WAN guards the network against vulnerabilities that MPLS cannot. The SD-WAN offers better visibility, availability, improved performance, and more freedom of action. This is why the business has seen interest in SD-WAN rising over the last few years. Another issue influencing that increase in interest is flexibility. MPLS connections tend to be rigid, fixed connections that can’t seamlessly adapt to the sort of interconnectivity between branch offices that today’s dynamic networks need. They also don’t offer support for application recognition or sophisticated bandwidth management for latency-sensitive use cases.

Previously, many enterprises connected remote branches and retail locations to the central data center through a hub and spoke WAN model that depended on individual MPLS connections. As an outcome, all data, workflows, and transactions, including access to cloud services or the internet, needed traffic to be backhauled to the data center for processing. Compared to an SD-WAN solution, this is extremely costly. SD-WAN reduces costs by offering optimized, multi-point connectivity using distributed, private data traffic exchange and control points to give the users secure, local access to the services they require– whether from the network or the cloud – while guarding direct access to cloud and internet resources.
