Why traditional WAN design no longer works

Traditional networks were designed around a single “best” connection per site.

That model struggles today because:

  • Cloud applications generate constant, distributed traffic
  • Voice and video are sensitive to latency and packet loss
  • Sites increasingly use multiple connection types
  • Backup circuits often sit idle until something breaks

Static routing cannot react quickly enough to changing network conditions.

The modern SD-WAN landscape

SD-WAN has moved from a niche enterprise technology to a practical solution for many organisations.

Key changes include:

  • Affordable access to multiple fixed and mobile connections
  • Increased reliance on SaaS and cloud platforms
  • The need to prioritise application performance, not just connectivity
  • Greater focus on resilience and user experience

SD-WAN provides dynamic control where traditional networks rely on assumptions.

Why multiple connections alone are not enough

Simply adding a second circuit does not guarantee resilience or performance.

Common issues include:

  • Traffic continuing to use a degraded primary line
  • Backup connections only activating after full failure
  • No visibility into application-level performance
  • Manual intervention required to resolve issues

Without intelligent routing, multiple connections still behave like a single point of failure.

What effective SD-WAN should deliver

A well-designed SD-WAN solution should provide:

  • Real-time monitoring of link quality and performance
  • Automatic routing decisions based on latency, jitter, and loss
  • Application-aware traffic prioritisation
  • Seamless failover without user disruption
  • Consistent performance across cloud and voice services

SD-WAN is about using connectivity intelligently, not just having more of it.

How BSAS approaches SD-WAN

BSAS designs SD-WAN solutions around real usage patterns and business impact.

We assess:

  • Which applications are business-critical
  • How performance degradation affects users
  • The mix of fixed and mobile connections available
  • Whether resilience, performance, or cost optimisation is the priority

Solutions are tailored to your environment rather than forcing a one-size-fits-all design.

Key capabilities of BSAS SD-WAN solutions

Depending on your environment and requirements, our services include:

  • Intelligent traffic routing across multiple connections
  • Application-level prioritisation for voice, video, and cloud services
  • Automatic failover and recovery based on real-time conditions
  • Centralised visibility into connection and application performance
  • Integration with existing firewall and security controls
  • Clear documentation of routing behaviour and priorities

These capabilities ensure SD-WAN delivers measurable performance and resilience benefits.

Why BSAS is different

SD-WAN is often oversold as a silver bullet. BSAS focuses on outcomes, not hype.

We differentiate by:

  • Applying SD-WAN only where it delivers genuine value
  • Designing policies based on how applications are actually used
  • Avoiding unnecessary complexity and vendor lock-in
  • Integrating SD-WAN with wider connectivity and security strategy
  • Supporting the service end-to-end, not just the overlay

The result is control and resilience without fragility.

How SD-WAN fits into a resilient strategy

SD-WAN acts as the intelligence layer across your connectivity estate.

When combined with:

  • Business broadband or leased lines
  • Backup connectivity (4G/5G or secondary fixed circuits)
  • Secure firewall and remote access services
  • Business Wi-Fi designed for capacity and reliability
  • Cloud and Microsoft 365 security controls

…it ensures applications continue to perform even during partial outages.

SD-WAN turns multiple connections into a single, resilient service.

Who this service is for

SD-WAN is well suited to organisations that:

  • Use multiple internet connections at one or more sites
  • Depend on cloud applications, Teams, or VoIP
  • Experience performance issues despite “working” connections
  • Need predictable behaviour during outages or degradation
  • Want visibility and control without manual intervention

If performance matters as much as uptime, SD-WAN is a strong fit.

Bringing intelligence to connectivity

Modern networks need to adapt in real time.

BSAS helps organisations:

  • Make better use of existing connections
  • Improve application performance and user experience
  • Reduce disruption during connectivity issues
  • Build intelligent resilience into the network

SD-WAN ensures your connectivity works for the business — not the other way around.
