How a Multi-Site Dubai Group Secured Its Network with Segmentation and FortiGate

Multi-Site F&B Group (Dubai) - Network Infrastructure & Security

Challenge

A growing food & beverage group operating multiple venues across Dubai had expanded faster than its network could keep up. The infrastructure had grown organically into a flat, largely undocumented topology — point-of-sale terminals, back-office accounting, CCTV and guest Wi-Fi all shared the same broadcast domain, with no isolation between sensitive systems and public traffic.

Leadership needed a clear, documented picture of what was actually running on the network, a firewall they could trust at the edge, and proper segmentation so a compromised guest device or POS terminal could never reach financial or management systems.

Solution

NOCKO began with a full L2/L3 topology audit, mapping every interface, VLAN and data flow into a single as-built diagram. We deployed a FortiGate firewall as the edge gateway handling NAT and secure IPsec VPN access for remote staff, and configured a Cisco Nexus core switch to perform inter-VLAN routing.

The flat network was re-architected into dedicated VLANs — corporate, point-of-sale, back-office, CCTV and guest — with access-control lists restricting the sensitive segments so that guest and public devices are fully isolated from financial and management systems. The entire design was documented and handed over as a maintainable reference.

Results

Re-architected a flat network into segmented VLANs with ACL isolation between sensitive and public traffic
Deployed a FortiGate edge firewall with policy-based control and NAT
Enabled secure remote access for staff via encrypted IPsec VPN
Fully isolated guest Wi-Fi and POS traffic from back-office and financial systems
Delivered a complete as-built L2/L3 topology diagram as a single source of network truth
"For the first time we actually know what our network looks like. Guest devices can no longer touch our POS or accounts, and remote staff connect securely. NOCKO turned a tangle of cables into a documented, defensible system."
