Segmenting a 200+ device flat network into isolated VLANs with firewall rules and zero-trust access policies.
Flat network with 200+ devices on the same subnet. No segmentation between production, IoT, and guest devices. One compromised device could pivot to everything.
8 isolated VLANs, 150+ firewall rules, zero-trust access policies. Lateral movement impossible between segments. 70% attack surface reduction.
8 isolated VLANs: Management, Production, IoT, Guest, VoIP, Security Cameras, Backup, and DMZ.
150+ inter-VLAN firewall rules with least-privilege access. Only explicitly allowed traffic passes.
NAC enforcement, 802.1X port authentication, and certificate-based device validation.
Real-time traffic analysis, anomaly detection, and automated alerting for suspicious cross-segment activity.
Flat networks are a security nightmare. Let's fix that.
