What STUV does
STUV (Steinbach & Vollmann GmbH) is a privately held German security technology manufacturer headquartered in Heiligenhaus, founded in 1883, that develops mechanical locking components and electronic access control systems for government and industrial customers. The company's product architecture centers on PYLOCX, a battery-free digital access control platform that combines electronic locking cylinders, padlocks, key depots, safe locks, container locks, and manhole locks with rechargeable PYKEY code keys, cryptographic PYCODE one-time codes, PYSUITE multi-client management software, PYGUARD LTE/LTE-M/450 MHz sensor monitors, and a PYAPP mobile application. PYLOCX is certified by the German Federal Office for Information Security (BSI) and by VdS, and is positioned for compliance with the EU Critical Entities Resilience (CER) Directive and German KRITIS requirements for critical infrastructure protection. STUV serves two primary customer segments, Justice/Police/Military/Government and KRITIS/Critical Infrastructure operators in energy, water, telecommunications, and transport, with additional business in industrial cabinet and door hardware, machinery locking, cold-room and refrigeration closures, elevator service, security service providers such as Prosegur, and security integrators. Revenue is generated primarily through one-time hardware sales of mechanical and electronic locking products, supplemented by custom engineering for correctional and specialized projects, optional PYSUITE software subscriptions on-premise or in the cloud, and a customer-initiated YOUR PRICE pricing system for catalog components. The company distributes through direct enterprise and government sales, a printed and PDF catalog, the YOUR PRICE online request channel, and channel partnerships with security integrators and door manufacturers, with claimed geographic reach across Germany, the United States, France, the United Kingdom, and Australia.
