SD-WAN and traditional WAN solutions

Smarter wide-area networking

SD-WAN is reshaping enterprise connectivity, reducing costs, boosting agility, and improving user experience. Clearlink Consulting helps IT teams compare WAN options and design resilient networks that support cloud adoption, hybrid workforces, and modern application performance.

Find the right-fit WAN solution for today’s demands and tomorrow’s growth.

Why traditional WANs fall short in today’s business environment

Think of traditional WAN as a highway system. It reliably connects you from place to place (office to office), but the routes are fixed, and building new roads is time-consuming and expensive.

Traditional WANs, especially those built on MPLS, were effective in a world where most applications and data lived in centralized data centers. But in a cloud-first world, those rigid, hardware-centric networks struggle to keep up.

The modern solution: What is SD-WAN?

If traditional WAN is the highway, SD-WAN is your GPS.

SD-WAN, or Software-Defined WAN, monitors all available roads (MPLS, broadband, LTE). It considers traffic conditions in real-time so it can direct your data towards the most efficient and cost-effective route. It can even switch roads mid-journey if a better one becomes available.

Benefits of SD-WAN:

Improved application performance with intelligent traffic routing

Maintain speed and reliability even during high bandwidth usage by prioritizing business-critical tools like VoIP and CRMs.

Cost savings by reducing reliance on expensive MPLS

Use more affordable internet connections while maintaining performance, significantly cutting network costs.

Faster site deployments and network changes

Add new offices or locations in days, not weeks. No physical lines or complicated on-site setup required.

Centralized, automated management

Manage network sites remotely. Update settings, apply policies, and troubleshoot, all from one interface.

Better cloud connectivity with direct-to-cloud access

Send traffic directly to the cloud to boost app speed and reduce latency, without bottlenecks.

Improved security via centralized control & SASE support.

Apply consistent security rules across every site and user, reducing gaps, simplifying compliance, and increasing control.

Whether you're facing rising network costs, slow cloud access, or growing demands across multiple locations, SD-WAN offers a flexible path forward.

SD-WAN vs. Traditional WAN: Which is right for you?

Not all businesses can walk away from traditional WANs overnight. MPLS still delivers consistent performance for mission-critical applications and is often necessary for:

Compliance-heavy industries like finance or healthcare
Sites with no access to high-speed broadband
Use cases with ultra-low latency requirements
Organizations still under long-term MPLS contracts

But for most medium to enterprise-level businesses, SD-WAN offers the modern evolution:

Greater agility for distributed teams
Optimized cloud and SaaS access
Easier scalability for new locations
Enhanced visibility and security

Each network has its place, and many organizations combine SD and traditional WAN, maintaining MPLS where needed and overlaying SD-WAN for better performance and cost control.

Let our team help you find the right balance for your network.
