INFRASTRUCTURE & NETWORK
SECURITY

Network and infrastructure security for organisations that can't afford to find out the hard way. We map your entire attack surface - on-premise, cloud, hybrid, and physical - identify every exploitable path through your environment, and build the architecture that closes them. From flat networks to misconfigured cloud buckets, we find what's exposed before someone else does.

The Problem
ONE FLAT NETWORK

Most commercial buildings put every device on the same network - IP cameras, HVAC controllers, access control systems, corporate laptops, and servers. This is a flat network, and it means an attacker who compromises a single cheap IoT device has a direct path to your most sensitive systems.

A real attack chain we have observed:
01→
Attacker identifies an IP camera on a building's WiFi from a parking lot using a laptop and a directional antenna.
02→
Camera has default credentials (admin:admin) - a 30-second Shodan search confirms the model, a known CVE provides instant root access.
03→
From the camera, the attacker scans the flat network - discovers the file server, HR workstations, and building management system on the same subnet.
04→
Lateral movement to the file server via an unpatched SMB vulnerability. Data exfiltration begins. The camera is the entry point - the server is the target.

Proper network segmentation would have stopped this attack at step 2 - the camera would have had no path to any internal system. That is what we build.

The same principle applies across every environment - a forgotten RDP port, a misconfigured cloud storage bucket, an overly permissive firewall rule. Attackers don't need sophistication when the basics are broken. Network security is not a product you buy - it is an architecture you build and a posture you maintain. We do both.

What We Cover
AUDIT SCOPE
IoT Device Inventory & Risk Scoring
We discover every connected device on your network - including shadow IT devices your team doesn't know about. Every device is categorised and risk-scored based on its exposure and known vulnerabilities.
Network Topology Mapping
Full documentation of your current network architecture - switches, routers, VLANs, firewall rules, and inter-network paths. Most clients are surprised by what is actually connected.
Firewall & ACL Rule Review
Systematic analysis of firewall policies and access control lists. We identify overly permissive rules, deprecated rules, and dangerous inter-zone policies.
Wireless Security Assessment
WiFi network audit including encryption standards, rogue AP detection, guest network isolation testing, WPA handshake capture, and PMKID attacks against accessible networks.
VLAN Segmentation Design
We design a segmented network architecture grouping devices by trust level and function - IoT VLAN, corporate VLAN, guest VLAN, OT/ICS VLAN - with strict inter-zone policies.
Penetration Testing
Active testing of the segmentation and firewall rules. We attempt to break out of each VLAN, bypass firewall rules, and achieve lateral movement - then report exactly how we did it.
Physical Access Point Review
Inspection of physical network infrastructure - exposed Ethernet ports in public areas, unlocked network cabinets, rogue devices plugged into unused ports.
Cloud Infrastructure Security Review
Assessment of cloud environments (AWS, Azure, GCP) for misconfigured storage buckets, overly permissive IAM policies, exposed management interfaces, insecure security group rules, and dangerous public-facing services. Cloud misconfigurations are the leading cause of enterprise data breaches.
VPN & Remote Access Security
Security assessment of VPN configurations, remote access gateways, and zero-trust network access implementations - identifying weak authentication, split-tunnelling risks, outdated VPN software with known CVEs, and insecure remote desktop exposures.
Our Approach
HOW WE WORK
01
Discovery & Asset Enumeration
Passive and active discovery of every device, service, and endpoint on your network - including shadow IT, forgotten cloud instances, and unmanaged devices your team doesn't know exist.
02
Topology Mapping & Architecture Review
Full documentation of current network architecture - on-premise and cloud. Firewall rules, VLAN structure, inter-zone policies, and trust relationships mapped and reviewed for security gaps.
03
Vulnerability Identification
Systematic scanning and manual analysis of all discovered assets - CVE exposure, default credentials, unpatched services, misconfigured cloud resources, and dangerous inter-network paths.
04
Active Penetration Testing
Attempted exploitation of identified vulnerabilities to confirm severity and map realistic attack chains. VLAN breakout attempts, lateral movement testing, privilege escalation, and cloud privilege abuse - every finding verified, no theoretical risks.
05
Architecture Design
Design of the hardened target-state architecture - segmentation scheme, firewall rule set, zero-trust access policies, and cloud security baseline - tailored to your environment and operational requirements.
06
Reporting & Implementation Support
CVSS-scored report with full attack chain documentation, hardened architecture blueprint, and prioritised remediation roadmap - plus hands-on support for your IT team through implementation and validation.
Deliverables
WHAT YOU RECEIVE
Full Network Topology Map
Documented diagram of your current state - every device, connection, and network zone. Often the first time a client has seen this.
Asset & Device Risk Register
Prioritised list of every discovered asset and device - CVE exposure, firmware version, default credential status, misconfiguration flags, and risk rating. Covers IoT, servers, cloud instances, and shadow IT.
Hardened Architecture Blueprint
Recommended target-state network design with VLAN scheme, firewall rule set, and inter-zone policy recommendations.
Penetration Test Report
All findings from active testing - CVSS-scored with attack chain documentation and remediation steps.
Implementation Support
We support your IT team through the implementation of the new architecture - answering questions, reviewing config changes, and validating the final state.
Executive Summary
A clear, jargon-free overview of your current security posture, critical findings, and prioritised recommendations - suitable for C-suite and board presentation with no technical background required.
