Network & Infrastructure Security
from the core to the edge

Design, build and review secure networks: architecture, segmentation, firewalls, secure remote access and platform-specific engineering.

Security Architecture Review

Independent review of your end-to-end architecture

Overview

We review how your controls fit together rather than one product at a time. The result is a clear view of strengths, gaps and overlaps, with a target architecture and roadmap that make your security investment work harder.

What we cover

Current-state architecture documentation
Assessment against NIST CSF and CIS Controls
Attack path and single-point-of-failure analysis
Target architecture and roadmap

Capabilities

Holistic view: Network, identity, endpoint, data and cloud controls assessed together.
Framework alignment: Findings mapped to the frameworks your auditors and regulators use.
Investment guidance: Where to invest, consolidate or retire tools for the best risk reduction.

What you receive

Architecture review report
Current and target architecture diagrams
Control gap register
Phased roadmap

Network Segmentation Services

Zones and micro-segmentation that contain attacks

Overview

Flat networks let ransomware spread in minutes. We map application dependencies, design zones around business risk and implement segmentation in stages, with testing at each step so services keep running.

What we cover

Application dependency and traffic mapping
Zone and trust-level design
VLAN, firewall and micro-segmentation implementation
Segmentation testing and validation

Capabilities

Traffic discovery: Observed flows show what really needs to talk to what before anything is blocked.
Staged enforcement: Rules applied gradually with monitoring, so business services are not disrupted.
Proof it works: Penetration tests confirm segments are isolated as designed.

What you receive

Traffic and dependency maps
Segmentation design
Implemented rules and change records
Segmentation test report

Network Security Architecture & Implementation

Design and build secure networks and remote access

Overview

From a new office to a national network, we design secure architectures and deliver them, including equipment sourcing through our ICT procurement team, configuration, testing and documentation.

What we cover

Next-generation firewall and perimeter design
Secure remote access and zero trust network access
Network access control for wired and wireless
Network monitoring and logging

Capabilities

End-to-end delivery: Design, procurement, installation and configuration from one accountable team.
Zero trust access: Users and devices verified before they reach applications, wherever they are.
Documented builds: As-built documentation and configuration standards your team can maintain.

What you receive

High- and low-level designs
Installed and configured infrastructure
Test and acceptance records
As-built documentation

Network Security Platform Specific Services

Expert services for leading firewall and network platforms

Overview

Network security platforms accumulate years of rules and settings. Our engineers review configuration health, remove unused and risky rules, migrate between platforms and versions, and can manage day-to-day changes for you.

What we cover

Firewall health checks and best-practice review
Rule-base clean-up and optimisation
Platform migrations and upgrades
Managed change and administration

Capabilities

Rule-base optimisation: Unused, shadowed and overly permissive rules found and removed safely.
Safe migrations: Policy conversion, testing and cut-over plans that avoid downtime.
Managed operations: Change requests handled by our engineers with approvals and audit trails.

What you receive

Health check report
Optimised rule base
Migration plan and records
Change management reports

Why it matters

Your network connects offices, data centres, cloud and remote staff. We make sure it is designed to contain attacks, configured correctly and monitored, so a single compromised device cannot reach everything.

Contained breaches:Segmentation limits how far an attacker can move.
Clean configurations:Firewall rule bases that are understood, documented and lean.
Secure connectivity:Branches, cloud and remote users connected through controlled paths.
Audit readiness:Network controls documented and evidenced for auditors.

How every engagement runs

The same disciplined approach, whichever service you choose.

Review
Assess current architecture, device configurations and traffic flows.
Design
Define zones, trust levels and the controls between them.
Implement
Configure and migrate with tested change plans and rollback steps.
Validate
Test that segmentation and controls work as designed, then monitor.
