Flat networks turn one endpoint into an organization-wide breach.
Flat networks let a single compromised endpoint become an organization-wide breach. Go2Duo designs segmentation architectures — VLANs, micro-segmentation, zero-trust access zones — that isolate critical systems like core banking, card data environments and payment gateways from general corporate traffic.
This directly reduces PCI DSS audit scope and limits how far an attacker can move if they get in.
Critical systems, walled off from general traffic.
Segmentation zones built around the systems that carry the most risk.
Core Banking
Isolated from general corporate and office network traffic.
Card Data Environments
Segmented to keep PCI DSS scope tightly bounded.
Payment Gateways
Access-controlled and monitored independently of the wider network.
Smaller blast radius, smaller audit scope.
The direct result of getting segmentation right.

From mapping to sign-off.
A structured path from your current environment to a validated segmentation model.
Map Your Environment
We build a complete picture of systems, traffic flows and dependencies.
Design the Model
We design the segmentation architecture — VLANs, micro-segmentation and zero-trust zones.
Implement Access Control
We implement the access control policies that enforce each zone's boundaries.
Validate Isolation
We validate isolation with targeted testing before final sign-off.
