A flat network where every device can talk to every other device is a security and performance liability. IT Umbrella Group designs and implements VLAN architectures that segment your traffic intelligently — improving security, performance, and manageability.
On a flat network, a compromised laptop can reach your file server, your accounting system, your cameras, and your VoIP phones without crossing a single security boundary. One ransomware infection, one malicious insider, or one compromised IoT device can reach everything.
VLANs create logical separation between device groups — workstations, servers, IoT, guest WiFi, POS, cameras — with firewall policies controlling exactly what can communicate with what. A breach in one zone is contained to that zone. IT Umbrella Group designs these architectures to match your actual business requirements.
IoT devices are a major attack vector. Smart TVs, IP cameras, HVAC controllers, and badge readers often have weak security and rarely get patched. Isolating them on a dedicated IoT VLAN — with no ability to reach your workstations or servers — removes them as a stepping stone for attackers.
Built for RGV businesses that can't afford downtime or surprises.
Getting started is easy. Here's exactly what happens from day one.
Both PCI-DSS and HIPAA require that systems handling sensitive data be isolated from the rest of your network. We design VLAN architectures that satisfy these requirements — reducing your compliance scope and your risk exposure simultaneously.
