Network infrastructure planning & review
Your network is the backbone of your business. Whether you're a growing SME setting up infrastructure for the first time, an established organisation that has outgrown its current setup, or an enterprise looking to validate and modernise a complex environment — our network infrastructure planning and review service gives you a clear, expert, and vendor-neutral picture of where you are and where you need to be.
Why network infrastructure planning matters
Many organisations run on network infrastructure that was never formally designed — it evolved organically as the business grew, adding equipment and connections reactively rather than strategically. The result is often a fragile, insecure, and inefficient environment that has become a barrier to growth rather than an enabler of it.
Poor network design is also a significant security risk. Flat networks with no segmentation, over-permissive firewall rules, unmanaged devices, and inadequate monitoring all create opportunities for attackers — and make containment far harder when incidents do occur. These are not problems exclusive to large enterprises; they are common across organisations of every size.
A structured review or planned deployment gives you documented, defensible infrastructure with the resilience, security, and scalability your business needs — and the clarity to maintain and evolve it with confidence.
Our services
The following destruction options are available.
Infrastructure review & audit
A structured assessment of your existing network environment — topology, hardware, configuration, segmentation, access controls, and monitoring capability. We identify risks, inefficiencies, and gaps, and deliver a clear findings report with prioritised recommendations.
- Full topology discovery & documentation
- Security configuration review
- Risk-rated findings report
- Remediation roadmap
Network design & planning
For new deployments, office moves, or significant infrastructure changes, we produce a detailed network design tailored to your size, sector, and security requirements. Designs are vendor-neutral, scalable, and delivered with full documentation including logical and physical diagrams.
- Logical & physical network diagrams
- IP addressing & VLAN planning
- Vendor-neutral recommendations
- Capacity & growth planning
Security architecture review
A focused assessment of the security posture of your network — firewall rules, segmentation, DMZ configuration, remote access, wireless security, and perimeter controls. We assess alignment with frameworks such as Cyber Essentials, ISO 27001, and NCSC guidance, and identify exploitable weaknesses before attackers do.
- Firewall rule review
- Segmentation & VLAN assessment
- Remote access & VPN review
- Wireless security assessment
Cloud & hybrid network review
For organisations with cloud-hosted workloads or hybrid on-premises/cloud environments, we assess how your network connects to and integrates with cloud platforms — covering connectivity, access controls, segmentation, and security configurations across AWS, Azure, and Google Cloud.
- On-premises to cloud connectivity review
- Cloud network security group assessment
- Hybrid identity & access review
- Covers AWS, Azure & Google Cloud
Documentation & diagramming
Many organisations have no accurate, up-to-date record of their own network. We survey, map, and document your environment from scratch — producing clear, maintainable network diagrams and asset inventories that support operations, audits, incident response, and onboarding.
- Logical & physical topology diagrams
- Asset inventory & device register
- IP address & VLAN documentation
- Delivered in editable formats
Scalability & modernisation planning
For organisations planning growth, acquisitions, or digital transformation, we assess whether your current infrastructure can support your future needs — and design a practical, phased modernisation roadmap to get you there without disruption to the business.
- Capacity & growth gap analysis
- SD-WAN, SASE & zero trust readiness
- Phased modernisation roadmap
- Budget & procurement guidance
Areas we cover
Our reviews and designs span the full breadth of modern network infrastructure, including:
Routers, switches & core LAN
Firewalls & perimeter security
Wireless & Wi-Fi infrastructure
VLANs & network segmentation
VPN & remote access
Server & data centre connectivity
WAN & SD-WAN
Network monitoring & logging
Cloud & hybrid connectivity
VoIP & unified communications
IoT & OT network isolation
Redundancy & failover design
Did you know?
- The majority of successful network breaches exploit misconfiguration rather than unpatched vulnerabilities — poor firewall rules and flat network design are more common attack vectors than zero-days.
- A flat network — one with no segmentation — means that a compromised device has potential access to every other device on the network, dramatically increasing the blast radius of any incident.
- Cyber Essentials requires boundary firewalls and internet gateways to be configured to block unauthenticated inbound connections by default — a requirement many organisations unknowingly fail.
- Many organisations discover undocumented devices on their network during an audit — rogue access points, forgotten servers, and unmanaged IoT devices are among the most common findings.
- The shift to remote working has fundamentally changed the network perimeter — traditional perimeter-only security is no longer sufficient for organisations with hybrid or distributed workforces.
- Network documentation is consistently cited by IT teams as one of the first things lost during staff turnover — undocumented infrastructure significantly increases incident response time and cost.
- SD-WAN and SASE adoption is accelerating among mid-market organisations, but without proper planning, migrations introduce new security gaps rather than eliminating existing ones.
