SERVICE SCOPE

What this service addresses

The critical topics this service addresses and the outcome we deliver in each.

Visibility into critical application traffic

evidence readiness

With flow, log and telemetry design we make branch and data center traffic visible and address bottlenecks at the root-cause level.

A prioritized, measurable roadmap

measured target

A prioritization matrix scoring business impact, security risk and operational bottlenecks yields an improvement plan tied to measurable targets.

Lower change and outage risk

contract-scoped

We proceed with change windows, a rollback plan and validation checklists, applying parallel running and controlled cutover for critical services.

Operations accelerated by standard documentation

contract-scoped

HLD/LLD designs, runbooks and monitoring dashboards reduce operational dependence on external support.

Delivery model

Delivery approach

How we phase the service across delivery, governance, and connected service pillars.

  1. We start with a current-state analysis: mapping topology, traffic and dependencies, then clarifying the critical application flow map, bottlenecks and the risk and compliance requirements.

  2. We design the target architecture for branch WAN/LAN/WLAN and the data center backbone, shaping SD-WAN, campus LAN/WLAN, segmentation (NAC/VLAN/VRF) and network visibility around measurable goals.

  3. We run the migration in phases, cut over with acceptance and failover validation, and complete performance monitoring and knowledge transfer through 30 days of hypercare support.

Operating contexts

Example operating contexts

Illustrative surfaces where this service is commonly activated.

Multi-site branch network standardization

Moving fragmented branch networks to a single standard with an MPLS/Internet/5G connectivity strategy and SD-WAN design.

Campus Wi-Fi 6/6E modernization

Renewing wireless access with a coverage and capacity plan based on a site survey or existing measurements.

Data center network backbone design

Designing the data center backbone and segmentation policies with a high-availability target.

DEPTH

Technical and compliance depth

This service's depth on sector-specific technical and compliance topics.

Segmentation and Zero Trust alignment

Network segmentation and the policy set are designed to align with your existing security architecture; policy points and log flow are handled together.

Monitoring platform integration

Integration with common platforms such as Zabbix, PRTG and Prometheus; flow/log/telemetry-based visibility and alarm definitions.

Controlled migration and acceptance criteria

Acceptance criteria defined through performance testing, capacity validation and failover testing; phased cutover supported by rollback procedures.

What It Solves

Legacy network architectures struggle to meet the demands of hybrid workforces, multi-site operations, and cloud-first application delivery. Organisations face escalating bandwidth costs, inconsistent user experience across branch locations, and insufficient visibility into network performance. Our Strategic Network and Data Center Transformation practice eliminates these bottlenecks by modernising connectivity, compute fabric, and data center topology end-to-end.

Frequently Asked Questions

How long does a typical SD-WAN migration take for a 50-site enterprise?

A phased SD-WAN migration for a 50-site enterprise is planned through a scoped timeline agreed during discovery. We use a pilot-site approach, validating QoS policies and failover behaviour in a controlled environment before rolling out to production sites in batches of 10 to 15 locations.

Can you integrate SD-WAN with our existing MPLS circuits during transition?

Yes. Our hybrid WAN design supports concurrent MPLS and SD-WAN operation, allowing a zero-disruption cutover. MPLS circuits are retained as a premium path for latency-sensitive traffic until the transition is fully validated and the business is ready to decommission them.

Do you provide network operations after the implementation is complete?

Yes. We offer tiered managed network services including contract-scoped NOC monitoring, incident response SLAs, quarterly health reviews, and capacity planning. Managed services are scoped separately and can be transitioned to in-house teams with full knowledge transfer.

How do you handle multi-vendor environments during a transformation?

We apply a vendor-neutral assessment methodology to catalogue all existing assets. Our architects design integration points that preserve existing investments where viable, define a deprecation roadmap for end-of-life equipment, and manage multi-vendor coexistence throughout the transition period.

Are the configuration templates reusable for future site expansions?

Yes. All configuration templates are designed as parameterised blueprints that can be adapted for new sites with minimal customisation. They are stored in a version-controlled repository and come with variable substitution guides so your internal team can deploy new sites independently.

What warranty or support period is included after project handover?

All deployments include a 90-day post-handover hyper-care period with priority access to the project engineers. During this window we respond to configuration-related issues within the agreed response window and provide up to 3 change requests at no additional cost.
