The Platform in Action
Real screenshots from production deployments — not mockups, not demos.
Live network graph visualization with node types, subnets, and topology filtering.
Built for Mission-Critical Training
Every capability designed to exceed what the world's top cyber range platforms offer.
IaC Orchestration
CoreTerraform + Jinja2 templates provision isolated exercise arenas in minutes. Every VM, network, and service defined as code.
Scoring & Analytics
Kill-chain coverage, MITRE ATT&CK heatmaps, MTTD/MTTR metrics, and per-participant skill gap analysis.
Multi-Tenant RBAC
6 roles with separation of duties. Platform Admin, Tenant Admin, Trainer, Team Lead, Trainee, and Observer.
Air-Gap Ready
SovereignZero external dependencies. No telemetry, no update beacons, no external cloud dependencies. Fully self-contained.
AI-Powered Training
Adaptive hints, intelligent difficulty calibration, AI-generated feedback, and personalized learning paths.
Template Import/Export
Portable exercise packages. Export from dev, import to production. Full topology, scripts, and scoring included.
Built on Open Standards
Every component uses open, auditable, standards-based technology. No proprietary hardware. No hidden dependencies. Source code escrow available for sovereign deployments.
