FAQ

Frequently asked questions

What is a network zone topology?01
A network zone topology is a diagram that groups devices into security or functional zones, showing how those zones are connected and what traffic is allowed between them.
Why do small businesses need zone-based network diagrams?02
Zone-based diagrams help small businesses enforce security policies, meet compliance requirements like PCI DSS, and simplify troubleshooting by making network segmentation visually clear.
What zones should I include in a small business network?03
Common zones include guest Wi-Fi, employee workstations, point-of-sale systems, security cameras, and a server or network equipment zone. The exact zones depend on your business operations.
Can I edit these examples for my own business?04
Yes. Every example is a starting point. You can change device names, add or remove zones, and rearrange connections to match your actual network.
How do I secure different network zones?05
Use firewalls to control traffic between zones, apply VLANs for logical separation, and restrict access from guest networks to internal resources. Our diagram tool lets you annotate these security controls.
