Next-Gen Firewalls & Perimeter Isolation
Enterprise Next-Gen Firewalls & VLAN Network Segmentation
Consumer routers leave entire offices exposed on flat networks. We engineer robust perimeter firewall architectures that isolate guests, servers, and IoT terminals.

Network Case Studies
Enterprise Firewall Deployments
Case Study #1 · Multi-Branch Network Isolation
Regional Financial Cooperative 4-Branch IPsec Mesh
Deployed dual high-availability Next-Gen Firewalls with redundant ISP failover, isolating teller workstations from public guest Wi-Fi and encrypting inter-branch core banking transactions.
Sub-second dual-WAN failover during ISP fiber outages
Zero unauthorized lateral movement between branches
Case Study #2 · DMZ Server Hardening
Manufacturing Plant DMZ & SCADA Isolation
Separated office administrative computers from factory floor CNC machines and IoT smart telemetry devices using isolated VLANs and strict outbound connection whitelisting.
Blocked unauthorized external beaconing and telemetry from factory devices
Complete audit log retention and continuous security telemetry
