Add-on gateway that enables transparent architecture without replacing your PACS

The HID M1 Transparent Gateway is a cryptographic security module designed to help high-security organizations meet transparent-architecture requirements by moving sensitive cryptographic operations away from perimeter readers into a physically secured location. It sits inline between existing OSDP controllers and readers, so organizations can strengthen security and compliance without a disruptive “rip-and-replace” of their installed access control infrastructure.

What it does

HID M1 performs the transparent-architecture cryptographic functions independently while preserving the existing controller-to-PACS (Physical Access Control System) behavior. From the access control system’s perspective, communication continues as before, enabling upgrades with minimal change to day-to-day operations.

Built for OSDP environments

OSDP (Open Supervised Device Protocol) is widely used to connect access controllers and readers. HID M1 is designed for OSDP deployments and supports secure, supervised communication, helping reduce exposure at the door and improve overall system robustness.

Modular architecture that scales by door

The solution is built around a Main Node with supporting modules, enabling incremental, door-by-door deployment. This allows organizations to protect the highest-risk entry points first and expand over time based on security priorities and budgets.

Key protection and cyber safeguards

HID M1 centralizes sensitive key material inside secured components and supports strong protection mechanisms such as secure boot, tamper protections, and authenticated firmware updates. The design aims to keep cryptographic keys and operations out of vulnerable perimeter devices.

For regulated and high-assurance facilities, HID M1 provides a pragmatic path to transparent architecture by adding an extra security layer to existing systems, reducing operational disruption, and preserving prior investments in controllers, software, and credentials.
