Never Trust. Always Verify.

At the centre of Zuppgate is a four-tier access control architecture, designed to accommodate different security and operational requirements. Physical access is not identical across every organisation: a routine office visit and a visit to a more restricted environment may require different levels of verification and oversight. Our four tiers allow organisations to choose the process appropriate to their requirements, bringing flexibility to how access is authorised and checked.

The purpose is to make verification proportionate and practical, with a clear procedure for the people implementing it. Hosts and administrators define the conditions of access, visitors understand the steps they must complete, and security teams follow the checks required by the selected tier. This creates a consistent framework for managing access while allowing organisations to apply the level of control their setting demands.

Our Zero Trust approach extends across the visit. An invitation records the host’s permission, but entry remains subject to the invitation’s validity, its conditions and the verification required by the chosen tier. Once the visitor enters, the same visit continues through a connected record, with visibility into entry time, visit status and authorised time remaining. Exit follows the procedure associated with the selected tier, completing the record of the visitor’s time on the premises.

By connecting these stages, Zuppgate helps teams answer practical questions: Is this visit authorised? Have the required checks been completed? Has the visitor entered? How much authorised time remains? Has the visitor exited? This continuity gives organisations a clearer basis for managing physical access from arrival to departure.

Zuppgate is designed to support physical access management across a wide range of environments—from apartments, residential communities and private homes to offices, schools, factories and large campuses. Its four-tier architecture accommodates progressively stricter access requirements, including those of VIP residences and offices, sensitive technology facilities and defence establishments. Organisations can select the level of verification and oversight appropriate to their premises, bringing everyday access and more demanding security workflows into the same platform.
