Air-gapped by hardware, not by a software switch. ## Secure from from CAD to printed part True security is a governed workflow, not just an offline printer. The attack surface is minimised across the entire data lifecycle. Isolation is physical, not a menu toggle. ![PrusaSlicer running locally without a network connection](https://assets.prusa3d.com/cdn-cgi/image/width=1200,quality=85,format=auto/8cb488be-b475-49a7-88b9-3bf4c9b06c8d.jpeg) Open, auditable software PrusaSlicer is open-source and runs on your own workstation. No cloud account, no subscription, no telemetry calling home. ![Prusa printer with no persistent mass storage](https://assets.prusa3d.com/cdn-cgi/image/width=1200,quality=85,format=auto/81254496-4a2c-436c-808b-62c03ec49eab.jpg) Zero residual data No internal mass storage. Volatile memory, including SRAM used for print buffering, is wiped by a power cycle. ![Hardware-encrypted USB transfer on a Prusa CI printer](https://assets.prusa3d.com/cdn-cgi/image/width=1200,quality=85,format=auto/https://storage.googleapis.com/prusa3d-content-prod-14e8-asset-manager-prod/3d87db04-11fa-47a0-99f9-d3f1bcec9747.jpg) No wireless radios CI electronics are custom-made with no wireless radios. An RJ45 port remains for an isolated LAN. No internet access needed. Ever. ![Prusa printer in a defence manufacturing environment](https://assets.prusa3d.com/cdn-cgi/image/width=1200,quality=85,format=auto/https://storage.googleapis.com/prusa3d-content-prod-14e8-asset-manager-prod/3b4b3f21-26cc-4285-9504-a829546eb78e.jpg) Camera-free workflows Machines ship without optical cameras. Files can be moved on hardware-encrypted USB. ![Open-source firmware that can be inspected and flashed offline](https://assets.prusa3d.com/cdn-cgi/image/width=1200,quality=85,format=auto/https://storage.googleapis.com/prusa3d-content-prod-14e8-asset-manager-prod/a3cf7b24-0a01-4c0e-91dd-719fe3c381fc.png) Offline firmware updates Updates arrive on a USB package you stage, validate, and approve. No forced online updates, no phone-home. ![Prusa CORE One L CI Edition operating offline](https://assets.prusa3d.com/cdn-cgi/image/width=1200,quality=85,format=auto/7c7b3639-1768-405c-a2df-f12e7376ada5.png) Optional LAN, never the internet Run on a dead-end VLAN or with no network cable at all. Setup and day-to-day printing never ask for internet access. ## Proč si vybrat tiskárny Prusa? Jsme česká firma s výrobou v Praze, Hradci Králové a v americkém Wilmingtonu.

Prusa is the remaining 5%. Country of origin matters. All Chinese companies are required to cooperate with state intelligence (National Intelligence Law, 2017), hand over encryption keys (Cryptography Law, 2020), and provide data to authorities regardless of where it's stored - even on EU or US servers (Data Security Law, 2021). Product designs and 3D models a legitimate target too (2023 Counter-Espionage Law update). > There is a real risk that data on prints, design models, or production processes could be transmitted to servers beyond the user's control, including to the territory of the PRC. 2025 — National Cyber and Information Security Agency ![National Cyber and Information Security Agency](https://assets.prusa3d.com/cdn-cgi/image/width=160,height=24,quality=85,format=auto/fb3d3032-422c-49b2-9427-cd45c0bad0d1.png) Jurisdiction follows the company, not the server. ## NATO armed forces trust Prusa printers Relied upon by the majority of NATO militaries for rapid prototyping and tactical part production inside strict SCIF environments.
