Network Infrastructure Consolidation: Halving Enterprise Network Costs While Elevating Reliability
Managed Connectivity • Network Re-Architecture • Cost Optimisation
Strategic Summary: Operating an unstable network with enterprise-level expenditure across multiple overlapping carriers, a multinational financial services firm engaged Si Futures. By identifying legacy Exchange bottlenecks, consolidating duplicate circuits, and deploying a hybrid MPLS/SD-WAN architecture, we halved total WAN spend while reducing support tickets by 70%.
Challenge: Complex Multi-Vendor Billing & Unstable Performance
A multinational financial services firm faced severe operational risks due to frequent network drops that directly damaged client trust and disrupted internal cross-border operations. Despite incurring enterprise-level budgets, the firm was receiving sub-par network performance.

The existing incumbent carrier urged a rapid, wholesale migration from MPLS to SD-WAN. However, executive leadership resisted, fearing major migration downtime and questioning whether an abrupt protocol swap would resolve the underlying performance issues. Multi-vendor billing opacity, unmonitored failover links, and hidden licensing charges obscured true operating costs and destroyed accountability.
Root Cause vs. Symptomatic Fixes
Our comprehensive review revealed that legacy, on-premises Exchange servers were causing severe network throttling. A wholesale SD-WAN swap would have cost hundreds of thousands without solving the core application bottleneck.
Approach & Re-Architecture Solution
Si Futures engineered a phased consolidation roadmap that protected business operations throughout the transition:
- Carrier Consolidation: Merged redundant, overlapping services across carriers into a single managed infrastructure framework.
- Tailored Hybrid MPLS / SD-WAN Topology: Assigned high-priority financial transactions to dedicated links while routing general cloud traffic over optimized SD-WAN paths.
- Proactive Monitoring & SASE Alignment: Integrated centralized telemetry alongside a forward-looking Secure Access Service Edge (SASE) architecture roadmap.
Measurable Outcomes & Operational Efficiency
Key performance and financial milestones achieved through network re-architecture:
- 50% Reduction in Total WAN Spend: Streamlined carrier contracts and eliminated duplicated circuits.
- 70% Reduction in Support Tickets: Enhanced stability and eliminated application throttling across all branch locations.
- Above-SLA Uptime: Consistent, high-availability application delivery matching stringent regulatory expectations.
- Unified Management: Replaced fragmented multi-vendor finger-pointing with a single, accountable point of contact.

Client Perspective & Strategic Growth
“We halved our network costs without compromising on performance. With Si Futures managing everything, our internal team finally had space to focus on growth initiatives rather than constantly firefighting network issues.”
By replacing multi-vendor chaos with a single managed partnership, the internal IT team freed up strategic capacity to focus on digital transformation initiatives.
