ENTERPRISE NETWORKING Zero-Trust ZTNA · Sub-Second HA Failover

Networks built to stay up.

Production-grade enterprise network engineering for fleet operators and maritime logistics: active-passive firewall clustering, WireGuard ZTNA meshes, multi-trunk SD-WAN, and sub-second path switching across satellite and shore links.

01 · Network engineering

Engineered for extreme reliability, at sea and on shore.

High availability, automated link steering, and cryptographic network isolation designed for commercial fleets.

STAGE 01 // HA CLUSTERING
NODE 01 ACTIVE · UP HEARTBEAT NODE 02 STANDBY FAILOVER: < 1.2s CONVERGENCE

Dual Firewall HA Clusters

Stateful active-passive clustering with synchronized connection tables. When one chassis suffers a power loss, traffic shifts sub-second without dropping active sessions.

STAGE 02 // MULTI-LINK SD-WAN
VSAT (PRI) LEO (SEC) 4G (PORT) SD-WAN POLICY MUX

Dynamic Multi-WAN Steering

Continuous jitter, loss, and latency monitoring across VSAT, Starlink, and in-port cellular. High-priority bridge traffic always gets the best available path.

STAGE 03 // ZERO-TRUST ZTNA
WIREGUARD TALLINN HQ AL KHOBAR VESSEL OT

WireGuard ZTNA Enclave

Zero exposed ports on public IP ranges. Every superintendent, analyst, and bridge node communicates exclusively over cryptographically authenticated WireGuard tunnels.
