The decision
Network Architecture
A network architecture review tests the real topology, dependencies, resilience and operating constraints before redesign or investment is committed.
The review starts with traffic paths and service behaviour, then identifies where design, configuration, ownership or documentation is constraining safe change.
Questions we help answer
The useful questions usually appear before the technology choice.
How we think
Engineering principles
The network should be explainable.
Segmentation must reduce risk without destroying operations.
Resilience is only useful when failure behaviour is understood.
Signals
When this needs attention
- Troubleshooting depends on a small number of individuals.
- Security boundaries are unclear or inconsistent.
- Wireless, routing or firewall changes routinely create unexpected side effects.
- Documentation describes intent rather than reality.
The Praetorian method
Understand. Design. Deliver. Improve.
Establish the real topology
Document how traffic, dependency, routing and access actually work.
Assess risk and changeability
Look for brittle paths, hidden coupling, operational gaps and constraints on future projects.
Design practical improvement
Prioritise changes that improve stability, security and explainability without unnecessary disruption.
Operational Intelligence
Evidence brought together before change begins.
Operational intelligence combines experience, engineering judgement, operational knowledge, vendor contribution, business context and analytical tooling to improve the decision before the environment is changed.
What good looks like
Clear decisions and controlled change.
