The Traditional WAN Wasn’t Built for Today’s Remote Workforce
When wide area networks (WANs) first emerged, they were designed for an era where most employees worked onsite and accessed applications hosted in centralized corporate data centers. Branch offices connected back to headquarters using MPLS links, and network traffic was predictable, internal, and relatively simple to secure.
But that model no longer fits.
The shift to cloud-first infrastructure and remote work has upended traditional WAN design. With employees now accessing cloud applications like Microsoft 365, Salesforce, and Zoom from anywhere—often directly from home or public internet connections—the old hub-and-spoke WAN model has become a bottleneck for performance, scalability, and security.
Enter Software-Defined Wide Area Networking (SD-WAN)—a modern solution purpose-built for today’s hybrid, distributed world.
Cloud Adoption + Remote Work = Urgent Need for SD-WAN
According to Nemertes Research’s Cloud, Network and Infrastructure: 2019-2020 Research Study, over 56% of enterprise workloads now run in external cloud environments. What’s more, fewer than a third of enterprises plan to return to a fully in-office model—meaning remote and hybrid work are here to stay.
That permanent shift in workforce distribution puts immense pressure on legacy WAN infrastructure. IT leaders must now manage:
- Thousands of remote endpoints
- Unpredictable cloud traffic patterns
- Security risks across public internet connections
- The need for consistent user experience—anywhere, anytime
Traditional MPLS just can’t meet these demands effectively or affordably. But SD-WAN can.
What SD-WAN Delivers for Distributed Teams
SD-WAN brings a cloud-native, software-defined approach to WAN architecture. It enables businesses to securely and intelligently route traffic across multiple types of connectivity—broadband, LTE, MPLS—based on real-time network conditions and application requirements.
For enterprises with growing remote workforces, SD-WAN offers powerful advantages:
1. Centralized, Policy-Driven Management
SD-WAN enables centralized orchestration of network policies. IT teams can easily set rules for how traffic should be routed, prioritized, or segmented based on business needs.
Example: Prioritize video conferencing traffic over email or social media during business hours. Automatically reroute traffic over LTE if broadband latency spikes.
2. Performance Optimization Across Any Connection
Instead of relying on a single MPLS line, SD-WAN can simultaneously use multiple transport paths—public internet, LTE, fiber—to boost availability and performance. Features like link bonding, dynamic path selection, and packet duplication help eliminate latency, jitter, and dropped calls.
This is critical when your workforce is dispersed across home networks, often using consumer-grade ISPs with inconsistent quality.
3. Built-In Security for a Cloud-First World
Modern SD-WAN solutions often integrate zero trust architecture, end-to-end encryption, and firewall capabilities directly into the WAN fabric. This reduces reliance on backhauling traffic through central firewalls and enables direct-to-cloud access with security baked in.
SD-WAN also supports microsegmentation and secure local breakout, giving IT granular control over what traffic can access which resources—no matter where a user is working.
4. Seamless Cloud and SaaS Connectivity
SD-WAN supports direct access to cloud applications from remote locations without routing everything back through a central data center. This reduces latency and improves user experience for critical tools like:
- Microsoft 365
- Salesforce
- Zoom/Teams/Webex
- Google Workspace
- Virtual desktops and cloud file storage
In short, SD-WAN delivers the performance your distributed workforce expects—and your IT team needs to provide.
Why SD-WAN Is a Game Changer for Network Teams
As organizations add more remote users, branch offices, and SaaS platforms, network teams face a growing burden. More locations mean more connections to manage, more endpoints to secure, and more issues to troubleshoot.
SD-WAN helps relieve that pressure through:
- Automation: Streamlines deployment and management across thousands of sites.
- Visibility: Provides real-time insight into traffic, performance, and security metrics.
- Flexibility: Easily integrates with cloud platforms, security tools, and third-party services.
- Speed: Enables faster rollout of new sites or remote users—without physical infrastructure changes.
DIY vs. Managed SD-WAN: Why More Teams Are Outsourcing
Many enterprises start with a DIY SD-WAN deployment, often leveraging existing IT staff and cloud providers. But as complexity grows—and network teams become stretched thin—fully managed SD-WAN solutions are becoming increasingly popular.
Benefits of a managed SD-WAN approach include:
- Accelerated deployment timelines
- Turnkey monitoring and support
- Integrated security services
- Guaranteed SLAs for uptime and performance
- 24/7 issue resolution from experts
For overburdened IT departments, this managed model frees up internal resources to focus on strategic initiatives like zero trust implementation, AI-powered security, or digital transformation efforts.
What to Look for in an SD-WAN Solution for Remote Work
If you're considering SD-WAN to support your remote or hybrid workforce, prioritize solutions that:
- Support zero trust network access (ZTNA)
- Provide secure remote access for mobile and home users
- Integrate easily with your cloud and security stack
- Offer application-aware routing
- Deliver real-time performance analytics
- Support multi-cloud and hybrid IT environments
Most importantly, look for a solution—and a partner—that understands your business objectives and tailors SD-WAN to meet them.
