jNet Custodia™ Pro

A white-label USB security token platform for OEMs and system integrators — built on secure-element hardware, Javelin™ OS, and certification-aligned deployment controls.

Available on Infineon SLC-series silicon. FIPS 140-3 targeted.

DISCRETE TOKEN ARCHITECTURE

Why a discrete bridge, not integrated USB?

Custodia Pro™ separates the USB interface from the secure element by design. The secure element communicates over ISO 7816, while a discrete USB-to-ISO 7816 bridge handles host protocol translation.

This keeps the secure-element boundary cleaner, reduces integration risk, and gives OEMs more control over certification, lifecycle management, and long-term platform ownership.

OEM Programme

Custodia™ Pro packages secure-element hardware, Javelin™ OS, applet support, and certification planning into an OEM-ready white-label platform.

White-Label Programme

White-label token platform under your control

Standard security keys leave OEMs and system integrators with limited control over firmware, applet extensibility, lifecycle policy, and long-term roadmap ownership. Custodia™ Pro closes that gap.
