SD-WAN · Connectivity & Network
SD-WAN for South African business — faster apps, lower MPLS costs, simpler ops.
Supercharge multi-site networks with application-aware routing, link bonding & healing, and zero-touch rollout. Prioritise VoIP, POS & SaaS, add built-in security, and manage every branch from a single pane of glass — backed by SLA-driven uptime and local support from Screamer.
Why businesses switch to SD-WAN
Cut jitter, speed up Microsoft 365 and POS, and simplify branches with app-aware routing and zero-touch rollout — all managed from one pane of glass.
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 and jitter, and heal brownouts automatically.
Centralised ops
Zero-touch turn-ups, a single policy for every branch, and clear telemetry for faster support.
SASE-ready security
Converge SD-WAN with cloud security (SWG/CASB/ZTNA) or integrate cleanly with your firewalls.
Cloud on-ramp
Direct, secure reach to Microsoft 365, Google, AWS — plus local peering for consistently low latency.
MPLS alternative
Flatten costs, add bandwidth fast and avoid long-tail provisioning delays.
How Screamer SD-WAN works
Bond diverse links, steer apps intelligently, deploy in minutes and add cloud security when you need it — all from one pane of glass.
Underlay choice
Use fibre, Business Wireless and LTE/5G together for path diversity and uptime.
Overlay & policies
We build app-aware policies once (voice, POS, CCTV, SaaS) — then push everywhere automatically.
Zero-touch rollout
CPE ships pre-provisioned; sites come online in minutes after power-up — configs sync from cloud.
Cloud & security
Add cloud on-ramp and SASE/NGFW as needed — fully managed or co-managed.

SD-WAN vs traditional WAN
Quick snapshot of how SD-WAN stacks up against MPLS/IPSec architectures across control, resilience, visibility, cloud, security and rollout time.
| 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
Proactive monitoring, controlled changes and transparent reporting — backed by SLA-driven targets.
24/7 SA-based NOC
Real-time monitoring, proactive alerts, ticketing and escalation targets.
Change control
Documented MACD for policy updates, IP changes and safe rollbacks.
Reporting
Monthly health stats: loss, jitter, latency, availability and usage.
SLA highlights
| Priority | Response target | Restore target | Update cadence |
|---|---|---|---|
| P1 — Critical outage | 15 minutes | 4 hours (best-effort with vendor/last-mile dependencies) | Every 30 minutes until stable |
| P2 — Major degradation | 30 minutes | 8 hours | Every 60 minutes |
| P3 — Minor impact | 4 business hours | Next business day | Daily |
| P4 — Service request / change | 1 business day | As scheduled (per change window) | On status change |
| Monitoring & NOC | 24/7 proactive alerts | SLA-backed per priority | Ticketing & email notifications |

Secure my businessSD-WAN — FAQs
What is SD-WAN?
Software-defined WAN that overlays your existing links (fibre, microwave, LTE/5G) and steers traffic with application-aware policies from a central controller.
How does SD-WAN speed up cloud apps?
It recognises apps such as Microsoft 365, Teams, POS and ERP, then selects the lowest-latency, lowest-loss path. Path conditioning reduces jitter and packet loss; QoS prioritises real-time traffic like voice.
Do we need to replace MPLS on day one?
No. Most customers start hybrid—keep MPLS where needed and add SD-WAN over broadband or wireless, then migrate site-by-site without risky cut-overs.
Can it bond links and fail over automatically?
Yes. Active-active or failover across fibre, microwave and LTE. If a path degrades, traffic heals in real time—users barely notice.
What about security and SASE?
Keep your NGFWs or converge with SASE (SWG/CASB/ZTNA). We add segmentation and identity-aware access to isolate branches, guests and IoT.
Managed vs co-managed SD-WAN at Screamer?
Managed: Screamer runs policy, monitoring and changes end-to-end. Co-managed: your IT shares control; we supply the platform, escalation and SLAs.
How fast can Screamer deploy new branches?
Zero-touch rollout: devices ship pre-provisioned and sync from cloud management. Branches usually go live as soon as access links are ready.
What SLAs and support are included?
SLA-backed uptime with proactive monitoring and South African support. Optional 24×7 cover for critical sites.
What hardware do you supply?
Enterprise SD-WAN CPE sized to your throughput and features (DPI, VPN, security). All cloud-managed for policy, firmware and analytics.
Will it work with our current ISPs and static IPs?
Yes. It runs over any serviceable access (fibre, fixed wireless, LTE/5G). Static IPv4/IPv6 and site-to-site VPNs are supported where required.
Where is Screamer SD-WAN available?
Nationwide in South Africa—Johannesburg, Pretoria, Cape Town, Durban—plus the many suburbs/estates listed on this page.
How is SD-WAN priced?
Based on site count, bandwidth, security options and whether it’s managed or co-managed. Contact us for an exact quote.
How do we get a proposal?
Quick discovery (sites, links, apps) → policy map → design + commercials. Start here: Speak to an expert.
