FAQ

Questions about network diagram templates

What is a network security architecture diagram?

It's a visual map of security controls, trust boundaries, and data flows within a network. It shows how firewalls, VPNs, IDS/IPS, and segmentation work together to protect assets.

Why do I need a security architecture diagram?

Diagrams help teams agree on security design, support audits (SOC 2, ISO 27001), speed up incident response, and communicate with stakeholders who don't read config files.

What symbols should I use?

Common symbols include firewalls (brick wall icon), routers (rectangle with arrows), VPN gateways (lock icon), cloud workloads (cloud shape), and segmented zones (dotted perimeters). Our tool includes a full set.

Can I diagram cloud security architecture with this tool?

Absolutely. The shape library covers AWS, Azure, and GCP security services like WAF, security groups, and cloud-native firewalls, plus generic shapes for multicloud and hybrid scenarios.

How do I keep the diagram updated as the network evolves?

Save your diagram as a project and return anytime to edit. Changes are versioned, and you can share a live link so everyone sees the latest version.
