Services
Enterprise Network Consultancy Services
Eight defined services covering network architecture, migration, and security — from discovery and design through migration cutover and assurance. Each is scoped as a fixed-term project, statement of work, or fractional engagement, with deliverables and outcomes agreed before work begins.
Network Transformation
Redesign of enterprise network architecture to support growth, resilience, or a change in operating model — typically triggered by acquisition, consolidation, or a move away from an ageing platform.
Typical Challenges
- Architecture has grown organically and no longer matches the business
- Mergers or acquisitions have left fragmented, inconsistent infrastructure
- Existing design can't support planned growth or compliance requirements
What We Deliver
- Current-state assessment and dependency mapping
- Target architecture design and technical roadmap
- Phased transformation plan with minimal operational disruption
Typical outcomes: a validated target architecture, an agreed transformation roadmap, and a phased delivery plan that de-risks the transition from current to future state.
Example deliverables: discovery and current-state assessment, target architecture design, phased transformation roadmap, technical governance and architecture review board support.
Network Refresh
Planned replacement of ageing switching, routing, and wireless estate reaching end of vendor support, delivered without disrupting live services.
Typical Challenges
- Core or edge hardware approaching end-of-life or end-of-support
- No clear replacement design or sequencing plan
- Refresh must happen around live operations with no acceptable downtime
What We Deliver
- Hardware and licensing lifecycle review
- Replacement architecture and phased rollout plan
- Site-by-site or estate-wide delivery coordination
Typical outcomes: a modern, vendor-supported estate delivered in planned phases, with configuration and cutover handled to avoid disruption to users or operations.
Example deliverables: lifecycle and dependency review, replacement design, rollout sequencing plan, site delivery coordination, as-built documentation.
Network Migration
Structured migration between platforms, providers, or physical sites, covering routing, switching, and WAN connectivity.
Typical Challenges
- Moving between network vendors or platforms without a defined migration path
- Multiple dependent systems need to move in a coordinated sequence
- Limited change windows and low tolerance for service disruption
What We Deliver
- Dependency mapping and migration sequencing
- Cutover planning, including rollback and fallback procedures
- Out-of-hours migration execution and validation support
Typical outcomes: a migrated network estate with validated routing, connectivity, and failover behaviour, delivered against an agreed change plan with tested rollback procedures.
Example deliverables: dependency mapping, migration runbook, cutover and rollback plan, out-of-hours execution support, post-migration validation testing.
Data Centre Migration
Consolidation and migration of data centre estate — workloads, connectivity, and security — into fewer, modern facilities or managed environments.
Typical Challenges
- Multiple legacy data centres with overlapping or duplicated infrastructure
- Consolidation spans several vendors, workloads, and security domains at once
- Migration must be sequenced to avoid extended service impact
What We Deliver
- Discovery, gap analysis, and consolidation planning across sites
- Hybrid connectivity design (P2P, IPsec, SD-WAN) during transition
- Coordinated migration of switching, security, and workloads
Typical outcomes: a consolidated data centre footprint, with legacy sites decommissioned in a controlled sequence and connectivity, security, and workloads migrated without unplanned outages.
Example deliverables: site discovery and gap analysis, consolidation plan, hybrid connectivity design, migration wave planning, decommissioning schedule.
Cloud Migration — AWS & Azure
Landing zone and connectivity design for workloads and data centre estate moving to AWS or Azure, including hybrid connectivity during transition.
Typical Challenges
- No defined landing zone or connectivity model for the target platform
- Existing on-premises security and segmentation needs to be replicated in cloud
- Hybrid connectivity is required during a multi-phase migration
What We Deliver
- Landing zone and network architecture design
- Hybrid connectivity design (VPN, Direct Connect/ExpressRoute, SD-WAN)
- Cloud-native segmentation and security policy design
Typical outcomes: a cloud landing zone and connectivity model that supports the migration programme end to end, with security and segmentation carried through from on-premises design.
Example deliverables: landing zone design, hybrid connectivity architecture, segmentation and security policy design, migration sequencing support.
Network Security
Segmentation and security architecture review for enterprise and data centre environments, including policy design and remediation planning.
Typical Challenges
- Flat or under-segmented network architecture increasing lateral-movement risk
- Security policy has grown inconsistently over time and needs review
- No clear remediation plan following an audit or assessment finding
What We Deliver
- Segmentation and security architecture review
- Micro-segmentation and policy design
- Remediation planning and phased implementation
Typical outcomes: a segmented, policy-governed network architecture with a clear remediation plan for any identified gaps, implemented in phases to avoid operational disruption.
Example deliverables: security architecture review, dependency and policy mapping, micro-segmentation design, remediation roadmap, phased implementation support.
Firewall Migration
Cross-vendor firewall replacement and policy translation, delivered with structured testing, cutover, and validation.
Typical Challenges
- Replacing or consolidating firewall platforms across vendors
- Existing policy sets are large, undocumented, or inconsistently applied
- Cutover must maintain continuity of security posture throughout
What We Deliver
- Policy translation and optimisation across platforms
- HA and routing design for the target platform
- Structured cutover with validation testing
Typical outcomes: a migrated firewall estate with policy, NAT, and security profiles translated and optimised, and continuity of security posture maintained throughout cutover.
Example deliverables: policy audit and translation, HA and routing design, cutover and rollback plan, validation testing, post-migration policy review.
Fractional Network Consultancy / Technical Leadership
Part-time senior technical ownership — design authority, delivery oversight, and escalation support — for organisations that need senior expertise without a full-time hire.
Typical Challenges
- No senior technical ownership for network architecture or delivery governance
- Internal teams need escalation support for complex or high-risk changes
- A programme needs design authority without justifying a permanent role
- An outsourced MSP or systems integrator needs holding to contracted scope, quality, and timelines
What We Deliver
- Design authority and architecture review board support
- Technical escalation and assurance for in-flight programmes
- Ongoing or programme-length fractional technical leadership
Typical outcomes: senior technical oversight embedded into the programme or team, providing design governance and escalation support on a scoped, part-time basis.
Example deliverables: architecture review and governance, technical assurance reporting, escalation support, HLD/LLD validation, ongoing advisory sessions.
