Offline-first hardware and sovereign software — no accounts, no telemetry, no cloud.
Network security, built in Germany. Netz + Sec.
Most security tools protect your systems by exposing your data. We build the alternative.
NetzSec makes hardware and software that stay on your machine, under your control — designed to be secure, private, and open. You should be in control of your own data, and you should be able to trust the tools you depend on.
- You own it, not us — no accounts to create, nothing to rent, no kill switch.
- Offline-first — tools run locally; your data never has to leave the device.
- No telemetry, no cloud lock-in — strict no-log by design.
- Auditable — read the source, hold the keys, keep the perimeter.
- Made in the EU — hand-assembled and flashed in Germany, under EU jurisdiction.
Professional, locally-first hardware and software for HID automation, OSINT, and network analysis. Powered by the ESP32-S3, offline by default, with local-first AI (Ollama, LM Studio, or any OpenAI-compatible endpoint) and a built-in MCP server for ChatGPT, Claude Desktop, and Cursor. Lifetime firmware updates, zero subscriptions.

Netz — German for network (Netzwerk); the z lands as a soft “ts”, so it reads nets.
Sec — security, said just like the word: sek.
Together they read as one word — network security — two halves interlocked into a shield: an N and an S.
