Before & After

The Transformation

The Challenge

Flat network with 200+ devices on the same subnet. No segmentation between production, IoT, and guest devices. One compromised device could pivot to everything.

The Result

8 isolated VLANs, 150+ firewall rules, zero-trust access policies. Lateral movement impossible between segments. 70% attack surface reduction.

Deliverables

What Was Built

VLAN Segmentation

8 isolated VLANs: Management, Production, IoT, Guest, VoIP, Security Cameras, Backup, and DMZ.

Firewall Rules

150+ inter-VLAN firewall rules with least-privilege access. Only explicitly allowed traffic passes.

Zero-Trust Policies

NAC enforcement, 802.1X port authentication, and certificate-based device validation.

Network Monitoring

Real-time traffic analysis, anomaly detection, and automated alerting for suspicious cross-segment activity.

Network Needs Hardening?

Flat networks are a security nightmare. Let's fix that.
