Network Audit · Portsmouth
Network Audit in Portsmouth
A network audit for Portsmouth organisations, which usually establishes that everything can reach everything. Most business networks are flat by accident — the till, the camera system, the visitor wifi and the finance workstation share one space — so a compromise anywhere becomes a compromise everywhere.
Why this comes up
The problem
Guest wifi is on the same network as the servers, and nobody knows what half the connected devices are.
What you get
What we deliver
- Every connected device discovered and identified, including the unmanaged ones
- Segmentation assessed — what can reach what, and what should not be able to
- Guest and operational technology separated from the corporate network
- Wireless coverage and authentication reviewed, including any shared passwords
- Remote access examined, since old arrangements outlive the people who needed them
- Documentation produced, because most networks have none that reflects reality

Network Audit in Portsmouth — common questions
- Why does a flat network matter?
- Because it removes every barrier after the first one. An attacker reaching any device — or ransomware arriving on a laptop — can then see file servers, backups and management interfaces, and segmentation is what turns an incident affecting one area into one affecting the business.
- What unmanaged devices turn up?
- Printers, cameras, door entry systems, building controls, a television in the boardroom and occasionally equipment from a supplier nobody remembers authorising. Many run old software that cannot be patched, which is precisely why they belong on their own segment.
- Is guest wifi really a risk?
- When it is not isolated, considerably. A visitor device, or a member of staff's personal phone, sitting on the same network as production systems means the guest network is effectively an unauthenticated entrance — and this arrangement is extremely common in older installations.
- Why does documentation matter?
- Because without it, nobody will change anything. A network whose layout exists only in one engineer's memory cannot be safely modified, and when that person is unavailable during an incident the response consists of tracing cables — which is a poor use of the worst hour of the year.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
