The problem
Flat networks with a consumer router are the norm in small offices, which means one compromised laptop reaches everything.
What we built
- pfSense firewall with explicit allow/deny policy, WAN/LAN separation and VLAN segmentation between zones
- Remote access over OpenVPN and IPSec, with DHCP and DNS resolution managed centrally
- Intrusion detection and prevention using Suricata and Snort, tuned against simulated attack scenarios
- Traffic analysis and verification with Wireshark and Nmap, plus scripted firewall-rule updates
- Step-by-step runbook and exported configuration so the build can be reproduced or handed over
