112 readiness
Policy, location, routing, and response quality connected in one operational model.

Network Segmentation
Segmentation separates public-facing, carrier-facing, PSAP-facing, administrative, monitoring and data services. The goal is not isolation for its own sake; it is controlled reachability that keeps emergency sessions working under stress.

What it does
Network segmentation limits how failures or attacks move across emergency communications infrastructure.
Segmentation helps protect ESInet functions, PSAP interconnects and administrative systems.
How it works
- Places functions into zones with explicit allowed flows.
- Controls access with firewalls, BCFs and identity.
- Monitors crossings for anomalies.
Key interfaces and protocols
- Firewalls
- BCF
- Routing policy
- Monitoring
Systems it interacts with
- Security
- BCF
- DDoS
- ESInet
- PSAP
Common failure modes
- Segmentation blocks legitimate location retrieval.
- Flat management networks expose critical functions.
- Emergency and admin traffic share a brittle path.
- Rules drift from documented architecture.
Implementation considerations
- Document every allowed emergency flow.
- Test from the caller side and PSAP side.
- Review rules after every architecture change.
Standards
- Operational security practices
- ETSI NG112 context
