Server & Intranet Security Consulting
A thorough review of your servers and internal network, delivered as a plain-language report with fixes ranked by risk.
Network Security Analysis
Remote or On-Site
Deep Analysis at the Layers Where Network Attacks Begin
Security review at the switching and routing layers — where the hardest-to-detect network problems usually hide.
Best suited for:
SMB
Organisation
Company
Usually answered within an hour during business hours
Antivirus and firewalls work at the upper layers. But if the network underneath is not configured correctly, an intruder already inside the office can move freely from one device to the next without a single alert firing.
This service focuses on those two layers: Layer 2 (switching — VLANs, ARP, port security) and Layer 3 (routing — ACLs, segmentation, inter-subnet rules). This is where problems live that a general review will never surface.
Suited to organisations that already run managed network equipment and want to confirm the configuration actually closes gaps, rather than merely keeping the network switched on.
The problems this usually solves
- Every device sits on one flat network — guests, staff, CCTV, and servers all mixed together.
- VLANs exist, but nobody has verified the separation actually holds.
- Switches and routers still run factory defaults from the day they were installed.
What you get
- VLAN configuration and network segment separation review
- Port security checks and ARP spoofing exposure testing
- Routing table and inter-subnet access rule (ACL) review
- Switch and router settings checked against standard hardening guidance
- Guest network isolation verification
- Findings report with example remediation configuration
- A current-state topology diagram of your network
How we deliver it
Data collection
Network device configurations are gathered and the topology mapped alongside your IT team.
L2 analysis
VLANs, trunks, port security, and resilience against switching-layer attacks are examined.
L3 analysis
Routing, ACLs, segmentation, and inter-subnet traffic rules are reviewed.
Report & discussion
Findings are written up with example fixes, then discussed with your team.
Questions about this service
This goes deeper into the network hardware itself — switches and routers. The other service takes a broader view including servers and access rights. If you are unsure which you need, describe your situation on WhatsApp and we will point you to the right one.
Managed equipment from common vendors: Cisco, MikroTik, Ubiquiti, TP-Link Omada, and Aruba. For unmanaged consumer hardware there is genuinely little to analyse — we tell you that honestly up front.
The report includes example configuration your IT team can apply directly. If you would rather we implement it, that falls under Intranet Network Maintenance.
