NETWORK INFRASTRUCTURE

Switches & Firewall Support

From VLAN design to firewall rule audits — we build and maintain the network layer everything else depends on.

Overview

We configure and support managed switches, routers and next-generation firewalls from vendors including Cisco, Fortinet, Sophos, pfSense and Ubiquiti. That covers VLAN segmentation, routing, VPN tunnels (site-to-site and remote access), and firewall policy design.

For existing environments, we start with a rule and topology audit — most firewalls accumulate years of rules nobody remembers the reason for. We clean that up, document the network, and put change control around it going forward.

What's included

  • Switch configuration — VLANs, trunking, port security, STP
  • Firewall policy design, NAT and rule-base audits
  • Site-to-site and remote-access VPN configuration
  • Bandwidth monitoring, QoS and traffic shaping
  • Network segmentation for security and compliance
  • Redundancy and failover (HA pair) configuration
  • Firmware updates and vulnerability remediation
  • Full network documentation and topology diagrams
