Core Capabilities

Six Network Disciplines.
One Cohesive Design.

Every PR network engagement covers all six disciplines — designed together so each layer supports the next. No bolt-ons, no afterthoughts.

LAN/WAN Architecture

Hierarchical three-tier designs (core/distribution/access) built around your actual traffic patterns, site count, and growth projections. Redundancy designed in from day one — not retrofitted.

Includes
  • Logical L2/L3 topology design with full VLAN scheme
  • Redundant uplink design (HSRP/VRRP/ECMP failover)
  • WAN circuit selection, sizing, and provider negotiation support
  • IP addressing scheme with future-growth subnet allocation
  • QoS traffic classification policy for voice, video, and data

Wireless & Wi-Fi 6/6E

Predictive Wi-Fi design based on site surveys — not guesswork. High-density environments, roaming, and 6GHz band planning for warehouses, offices, campuses, and healthcare facilities.

Includes
  • Predictive RF site survey and AP placement plan
  • SSID architecture: guest isolation, BYOD, IoT segmentation
  • Wi-Fi 6/6E channel plan and power level optimisation
  • Seamless roaming configuration (802.11r/k/v)
  • Post-deployment validation survey with heatmap report

Network Security & Zero Trust

Security-first architecture with micro-segmentation, network access control, and zero-trust principles applied at every layer — from the perimeter down to individual VLAN policies.

Includes
  • Next-generation firewall policy design (NGFW/UTM)
  • Micro-segmentation with VLAN/VXLAN isolation
  • Network Access Control (NAC) — 802.1X, certificate-based auth
  • Zero-trust network access (ZTNA) architecture design
  • CIS Benchmark hardening of all network devices

SD-WAN & Cloud Connectivity

Intelligent WAN with application-aware path selection, automatic failover, and direct cloud breakout — so latency-sensitive apps don't bottleneck through a congested data centre.

Includes
  • SD-WAN platform evaluation and architecture design
  • Application-aware routing policies and SLA-based path selection
  • Direct internet access (DIA) with secure cloud breakout
  • MPLS-to-SD-WAN migration planning and cutover execution
  • Multi-site hub-and-spoke or full-mesh topology options

Performance & Monitoring

End-to-end observability from day one — not as an afterthought. Baseline performance measurement before deployment, then continuous monitoring with alerting and capacity trending.

Includes
  • Network performance baseline report (pre and post-design)
  • SNMP/NetFlow monitoring configuration with PRTG/Zabbix/SolarWinds
  • Alert threshold design and escalation runbook
  • Capacity planning dashboards with 12-month growth projections
  • Quarterly performance review with optimisation recommendations

Segmentation & IPv6 Readiness

Clean VLAN architecture, VXLAN overlay for modern environments, and full IPv6 dual-stack planning so your network is ready for growth today and compliant with future addressing requirements.

Includes
  • VLAN rationalisation audit and clean segmentation design
  • VXLAN overlay architecture for east-west traffic isolation
  • IPv6 dual-stack planning and implementation roadmap
  • Inter-VLAN routing policy with ACL documentation
  • IoT and OT network isolation with dedicated security zone

Every Engagement

Six Deliverables Included
in Every Network Design.

Whether you're replacing a single-site network or redesigning a multi-site WAN, these six outputs are delivered as standard with every PR network engagement — not billed as add-ons.

Physical & Logical Topology Diagrams

Full L1/L2/L3 diagrams in Visio and PDF — physical cabling layout, logical routing topology, VLAN map, and site-to-site connectivity. Yours to keep, update, and hand to auditors.

IP Addressing Scheme & VLAN Register

Complete IP address plan: subnet allocations, DHCP scope definitions, reserved ranges, and a VLAN register with name, ID, purpose, and VLAN-to-zone mapping. Updated as-built.

Firewall Policy Audit & Ruleset Documentation

All firewall rules documented with source/destination/purpose. Redundant, shadowed, and overly-permissive rules identified and remediated before handover. Clean policy from day one.

Wireless Coverage Map & RF Report

Pre-deployment predictive survey and post-deployment validation heatmap showing signal strength, channel utilisation, and coverage gaps per floor/zone. Included for every wireless project.

Pre & Post Performance Baseline

Measured network performance before and after the design — latency, throughput, jitter, and packet loss per segment. Proves the improvement with hard data, not just a verbal assurance.

Failover Testing & DR Connectivity Validation

Every redundant path — dual uplinks, failover routes, and HA pairs — tested and documented before handover. Failover behaviour, recovery time, and any caveats all recorded in the test report.

Engagement Process

Discovery to Optimisation —
Every Phase Has a Named Output.

Four structured phases, each ending with a specific deliverable. You always know where we are and exactly what you're getting.

Wks 1–2 01 — Discover

Network Discovery

We map your existing network end-to-end — every device, every link, every policy. We capture traffic patterns, measure performance, and identify every risk and constraint before designing anything.

  • Automated network topology discovery (CDP/LLDP/SNMP)
  • Traffic analysis: top talkers, application flows, peak usage
  • Configuration review: all switches, routers, firewalls
  • Security posture review: open ports, unused rules, EOL firmware
  • Stakeholder interviews: performance pain points, growth plans
Deliverable Network Discovery & Risk Report
Wks 3–4 02 — Design

Network Architecture Design

We produce the complete target-state design — logical and physical diagrams, device configurations, IP addressing, security policies, and a phased implementation plan.

  • High-level and low-level design (HLD + LLD) documents
  • Device selection and bill of materials with 3-year TCO
  • IP addressing scheme and VLAN register
  • Firewall policy design and security zone architecture
  • Design review and approval with client stakeholders
Deliverable HLD + LLD Design Pack & BoM
Wks 5–10+ 03 — Build

Implementation & Cutover

Change-controlled deployment following the approved design. Every change is peer-reviewed, every cutover has a rollback plan, and every step is tested before being handed over.

  • Staged deployment: lab validation → pilot site → full rollout
  • Pre-change testing and post-change validation at each step
  • Zero-downtime cutover for production environments
  • As-built documentation updated in real time
  • Failover and redundancy path testing before sign-off
Deliverable Deployed Network + As-Built Pack
Ongoing 04 — Optimise

Optimisation & Ongoing Support

Post-deployment monitoring, tuning, and capacity management — with regular reviews to keep your network ahead of demand as your business grows and your applications evolve.

  • 90-day hypercare period post-deployment
  • Monthly performance review with trending analysis
  • QoS and routing policy tuning based on live traffic data
  • Quarterly capacity review with scaling recommendations
  • Annual network architecture review and refresh roadmap

Our Approach

6 Network Problems
We're Called In to Fix.

These are the most common network anti-patterns we find on first engagement — and exactly how we replace them with something that works.

01
Flat Network with No Segmentation The most common finding — and the most dangerous
Problem

All devices on one or two VLANs. A compromised endpoint can reach every server, printer, and management interface on the network with no lateral movement restriction.

Our Approach

Logical security zones (user, server, management, IoT, guest, DMZ) with inter-VLAN routing controlled by explicit firewall policy. East-west traffic inspected, not assumed trusted.

02
Single WAN Uplink with No Failover One circuit failure = full business outage
Problem

One ISP circuit, no 4G/5G failover, no tested failover procedure. When the circuit goes down — scheduled or not — the whole site loses connectivity until it comes back up.

Our Approach

Dual uplinks from diverse providers (or SD-WAN with 4G failover), automatic failover under 30 seconds, and tested failback procedures. Documented, validated, and monitored.

03
No Documented IP Addressing Scheme Makes every change painful and risky
Problem

IP addresses assigned ad hoc. No VLAN register. Subnets overlap. Engineers spend hours tracing addresses before any change. New devices get squeezed into already-full ranges.

Our Approach

A structured IP addressing plan with a supernet split by function, growth allowance built in, DHCP scopes documented, static allocations registered, and a VLAN register maintained as a living document.

04
Firewall Rules That Nobody Understands Hundreds of rules, zero documentation
Problem

Firewall built up rule by rule over years. No names, no comments, shadowed rules that never match, "any/any" policies added to fix problems quickly. Nobody wants to touch it in case something breaks.

Our Approach

Full firewall audit: identify shadowed, redundant, and overly-permissive rules. Rewrite from a clean baseline with named rules, documented purpose, and an application-aware policy where the platform supports it.

05
Wireless Deployed Without a Site Survey Dead zones, co-channel interference, roaming failures
Problem

APs placed based on gut feel or contractor convenience. Channel plans not configured. Multiple APs on the same channel cause co-channel interference. Users can't roam between floors without reconnecting.

Our Approach

Predictive RF site survey before any AP is ordered. Channel plan configured, power levels optimised, seamless roaming enabled (802.11r/k/v). Post-deployment validation survey confirms coverage before sign-off.

06
Network Monitoring as an Afterthought Finding out about problems from users — not alerts
Problem

SNMP configured to send traps to an email address nobody checks. No bandwidth utilisation visibility. Interface errors not alerted. Performance problems only discovered when users complain.

Our Approach

Monitoring designed as part of the network — not bolted on afterwards. SNMP/NetFlow with meaningful alert thresholds, bandwidth dashboards, anomaly detection, and an escalation runbook for every alert type.
