What we do

Pentesting

We break in so attackers can't. Findings written for the people who fix them.

GreyNETnetwork designer

Design networks at five scales — a single rack, a city, the planet, orbit, and a Voyager link budget. Offline. CAD-style. Bring your own AI key.

GreyNET local view: a single site with Internet, DMZ, and Internal security zones, an edge firewall, core switch, web server, Postgres database, and a user PC laid out CAD-style.
Local Devices, security zones, and links inside one site. Drag a switch onto the canvas. Auto-connect fills in what you forgot.
GreyNET city view: traffic cameras, signals, and vehicle sensors pinned across Manhattan on an OpenStreetMap backdrop with fiber and microwave links between them.
City Endpoints on a real map. Pin a fiber junction at 42nd & Broadway. OpenStreetMap, Google Maps (BYO key), or an offline image.
GreyNET planet view: data center, HQ, and branch sites pinned by latitude and longitude on a night-Earth photo backdrop, connected by leased line, WAN, and management VPN links.
Planet Sites pinned by lat/lng on a night-Earth photo backdrop. Optional live overlays: city lights, plane tracks, satellite passes.
GreyNET orbit view: LEO, MEO, GEO satellites and a space station around Earth, with ground stations in Tokyo and New York, plus inter-satellite laser and RF links.
Orbit LEO, MEO, GEO, and space stations with coverage cones, inter-satellite links, and ground station handoffs.
GreyNET deep space view: heliocentric solar system with the Sun, Mercury, Venus, Earth, and Mars positioned, an X-band link arcing from DSN 70m Goldstone to Mars, and a Link Budget Studio side panel showing TX power, antenna gain, frequency, FSPL, and one-way light delay.
Deep Space DSN 70m antenna pointed at Mars. 326M km · 18 min one-way light delay. Slide TX power up — watch the link margin breathe.

What’s in the box

interplanetary

Link Budget Studio

DSN ↔ Voyager 1. Apollo S-band. JWST Ka downlink. Slide TX power, modulation, and FEC — watch FSPL, C/N₀, achieved Eb/N₀, link margin, and one-way light delay update live.

security

Vulnerability scan, baked in

Every design grades itself. Duplicate IPs and MACs. Exposed devices. Cross-zone links without inspection. Export the graded HTML report.

visualization

Live Planet overlays

Night-Earth photo backdrop with city lights, plane tracks, and satellite passes layered on top. Looks like an NOC wall in your laptop.

optional ai

Ask AI

Describe what you need. An LLM populates the diagram. Bring your own Anthropic or OpenAI key — encrypted at rest by the OS, never seen by the renderer.

heuristics

Auto-connect

Heuristically wires up the links you forgot. Saves the hour you’d spend tracing fiber from rack to rack.

offline-first

Yours, on disk

Windows desktop. JSON save/load. Autosave every 5 seconds. Exports PNG / SVG diagram, HTML security report, HTML specs, CSV cost estimate.
