WAN Architecture & SD-WAN
Multi-site connectivity with intelligent traffic routing, automatic failover and centralized policy — branch networking that stops being a support-ticket generator.
What we deliver
Branch connectivity used to be a choice between expensive-but-predictable MPLS and cheap-but-chaotic internet. SD-WAN ended that: application-aware routing across multiple links, sub-second failover, and centralized policy that treats fifty branches as one network instead of fifty snowflakes.
Enrich designs and operates WANs for organizations whose branches are not optional — banks, government field offices, industrial sites. That means engineering for Indian last-mile reality: dual-carrier diversity, 4G/5G fallback, QoS that protects voice and payments when a link degrades, and secure local internet breakout for cloud traffic instead of hairpinning everything through headquarters.
SD-WAN is also a security decision: we integrate the overlay with Zero Trust and SSE architectures so branch traffic gets the same policy as headquarters — a natural pairing with our Zero Trust practice.
What's included
SD-WAN Design & Deployment
Application-aware overlays on Fortinet, Cisco or Juniper — policy defined once, enforced at every site.
MPLS Migration & Hybrid WAN
Staged moves from pure MPLS to hybrid or full-internet underlay — cost down, capacity up, zero leap-of-faith cutovers.
Link Resilience & Failover
Dual-carrier, 4G/5G-backed designs with sub-second, session-preserving failover — an ISP outage becomes a log entry, not an incident.
QoS & Application Steering
Voice, video and transaction traffic protected per-application — brownouts stop taking the important things down with them.
Secure Local Breakout
Direct-to-cloud traffic with SSE/firewall policy at the edge — SaaS performance without backhaul latency.
Centralized Operations
Single-pane orchestration, zero-touch branch provisioning and change control across the whole estate.
From assessment to operations
Assess
Per-site link audit, application traffic profile and a cost model — what MPLS is buying you, and where it isn’t.
Design
Underlay/overlay architecture, carrier strategy and security integration, sized per site tier.
Deploy
Zero-touch provisioning in waves: pilot sites prove the design, then rollout scales — remote hands, not engineer road-trips.
Operate
Link-health monitoring, carrier escalation, policy tuning and monthly per-site reporting.

Common questions
Can we actually drop MPLS, or is that vendor talk?
+
Many can, some shouldn’t — the honest answer depends on your applications. Real-time traffic between fixed sites still benefits from MPLS-grade determinism; most everything else rides well on diverse internet links with application-aware steering. Hybrid designs capture most of the savings without betting the payments system on a single carrier’s last mile.
How does SD-WAN handle India’s last-mile reliability problem?
+
By assuming it: dual underlays from different carriers on different physical paths, 4G/5G as tertiary, and per-packet link measurement that steers traffic away from degradation before users feel it. Failover preserves sessions, so a flapping link doesn’t drop calls. Carrier diversity engineering is where Indian WAN designs are won or lost.
Does SD-WAN replace our branch firewalls?
+
Increasingly, yes — platforms like Fortinet Secure SD-WAN put NGFW and overlay in one device, and pairing the WAN with SSE moves inspection to the cloud edge for internet traffic. Whether that fits depends on your compliance and inspection needs per site; we design the security architecture and the WAN together, not as separate projects.
What does the rollout look like for 50+ branches?
+
Waves with zero-touch provisioning: devices ship pre-registered, a branch comes up by being plugged in, and configuration arrives from the orchestrator. A pilot wave of representative sites validates the design; after that, rollout pace is set by shipping logistics, not engineering. Fifty sites is a quarter’s work, not a year’s.
