SD-WAN — app-aware performance, zero-touch rollout, simpler ops.
Replace rigid WANs with cloud-smart routing. Prioritise voice, POS and SaaS, heal links in real time, and manage every site from one pane of glass.
Why businesses switch to SD-WAN
App-aware performance
Prioritise voice, card machines and SaaS with policies that follow the app, not the circuit.
Active path control
Use fibre + wireless underlays at once, steer around loss/jitter, and heal brownouts automatically.
Centralised ops
Zero-touch turn-ups, a single policy for every branch, and clear telemetry for support.
SASE-ready security
Converge SD-WAN with cloud security (SWG/CASB/ZTNA) or integrate with your firewalls.
Cloud on-ramp
Direct, secure reach to Microsoft 365, Google, AWS and local peering for low latency.
MPLS alternative
Flatten costs, add bandwidth fast, and avoid long-tail provisioning delays.
How Screamer SD-WAN works
- Underlay choice: Use fibre, Business Wireless, and LTE together for diversity.
- Overlay & policies: We build app-aware policies (voice, POS, CCTV, SaaS) once—then push everywhere.
- Zero-touch rollout: CPE ships pre-provisioned; sites come online in minutes after power-up.
- Cloud & security: Add cloud on-ramp and SASE/NGFW as needed—managed or co-managed.

Industries & use cases we power
Retail & QSR
Keep tills, loyalty and Wi-Fi responsive; prioritise POS & back-office, with LTE/fibre diversity.
Construction & sites
Zero-touch branches with wireless/LTE underlay; secure tunnels to HQ and cloud.
Logistics & yards
SD-WAN + Private APN: track fleet/IoT reliably; shape video & scanners without drops.
Financial & pro-services
Traffic engineering for UC, VDI and backups; segment traffic and enforce policy cleanly.
Multi-site healthcare
Prioritise EHR and imaging; segment IoT/clinical devices with intent-based policy.
Manufacturing
Stable links for MES/SCADA; backhaul CCTV without killing office traffic.
SD-WAN vs traditional WAN
| Capability | SD-WAN | Traditional WAN (MPLS/IPSec) |
|---|---|---|
| Traffic control | Application-aware, per-flow steering | Per-circuit, static routes/QoS |
| Resilience | Active-active over multiple links | Failover only; adds latency on backup |
| Visibility | End-to-end telemetry & single policy | Fragmented device views |
| Cloud access | Direct cloud on-ramps & peering | Backhaul to DC; hair-pinning |
| Security | SASE/NGFW integration | Appliance-by-appliance add-ons |
| Turn-up | Zero-touch (days) | Truck-rolls (weeks) |
SLA & support
24/7 SA-based NOC
Real-time monitoring, proactive alerts, ticketing and escalation targets.
Change control
Documented MACD for policy updates, IP changes and rollbacks.
Reporting
Monthly health stats: loss, jitter, latency, availability, and usage.
SD-WAN FAQs
What is SD-WAN in plain English?
A software-defined overlay that uses app-aware policies to steer traffic across multiple links, centrally controlled and monitored.
Do I have to replace MPLS on day one?
No. Many customers start hybrid—keep MPLS where needed, add SD-WAN over fibre/wireless/LTE, and migrate by site.
Can SD-WAN help voice quality?
Yes—policies detect voice and prioritise, while path conditioning avoids loss/jitter, improving MOS.
What about security?
Either integrate your NGFWs or converge via SASE (SWG/CASB/ZTNA) with identity-aware access and inline threat protection.
Ready to simplify your WAN?
We’ll map your apps, design policies, and roll out zero-touch—typically in days.
