PUBLIC CASE LIBRARY

See the value of networks
in real operations.

Network modernization determines whether transactions continue, employees reach the right systems, and hundreds of sites run to one standard. These cases come from public vendor sources—not endorsements by Ying Tai Yuan Communications—and separate facts, business impact and reusable design lessons.

SECURE SD-WAN + SD-BRANCH

THE PAPER STORE

Primary circuits failed.
Peak-season sales continued.

AUTOcellular failover during circuit outage

THE OPERATING REALITY

A store outage becomes lost revenue immediately.

The specialty retailer runs nearly 90 stores and a large distribution center. As locations grew, legacy WAN cost and complexity increased. Peak season also represents a material share of annual revenue, so circuit failure can immediately disrupt card authorization, checkout and customer service.

THE NETWORK RESPONSE

Turn backup connectivity into an automatic operating mechanism.

SD-WAN, security, switching and wireless were managed together at the branch, with cellular as backup. The network continuously assessed the primary circuit and failed over when needed, without requiring store staff to diagnose links, reconfigure equipment or coordinate multiple vendors.

WHY IT MATTERS

The outage happened. Customers did not feel it.

The published case records primary-circuit failures at several stores during the busiest season, including a top-performing location. SD-WAN and cellular backup kept transactions moving. The differentiator was not raw speed—it was continuity.

ZERO TRUST ACCESS

EQS GROUP

Give global teams app access
without relying on legacy VPN.

THE OPERATING REALITY

Business growth outpaced VPN operations.

EQS Group was expanding geographically and through acquisitions while supporting hybrid work. Legacy VPN access was unreliable and depended on outsourced troubleshooting. Each acquired team added another round of infrastructure deployment and configuration.

THE ACCESS RESPONSE

Move access decisions from IP addresses to identity and device posture.

Zero Trust validates identity and device context on each request, then exposes only authorized applications by role. Employees no longer need broad network access, while IT can update permissions centrally as people join, move or leave.

WHY IT MATTERS

New-team onboarding fell from weeks to hours.

The published story reports 700+ global users migrated and acquired-team onboarding reduced substantially. The defining benefit is organizational agility—network and security no longer delay people from becoming productive.

SD-WAN + CENTRAL CONTROL

SUPERTIENDAS OLÍMPICA

More than 400 sites,
operating to one standard.

ONEnetwork and security control view

THE OPERATING REALITY

More sites create more configuration drift.

Large retail networks carry ERP, POS, workforce collaboration and guest Wi-Fi at once. At hundreds of sites, store-by-store configuration leads to policy drift, slow changes and difficult troubleshooting, while capacity and security become harder to modernize together.

THE SCALE RESPONSE

Orchestrate connectivity, security and branch access together.

The design brought SD-WAN, branch networking and security policy into one management plane and used standardized templates for rollout. Headquarters could push rules centrally, see site health, and provide consistent secure access to ERP, POS and collaboration tools.

WHY IT MATTERS

Every policy change becomes a controlled action at scale.

The official case reports 400+ sites under centralized management, faster policy deployment and improved critical-system access. The standout capability is standardization—new stores, existing sites and regions no longer become separate network islands.

FROM EVIDENCE TO DESIGN

Cases show direction.
Assessment defines the answer.

Ying Tai Yuan Communications does not apply someone else's numbers to your business. We validate application dependencies, site variation, existing circuits, outage cost and security needs before defining a pilotable, reversible and scalable plan.

01Quantify interruption cost
02Prioritize critical applications
03Pilot representative sites
04Validate with metrics, then scale
