SYSTEM FOR ACCESS TO SECURE DATA NETWORKS

The invention relates to a system for secure, controlled, orderly and collaborative access to secure data networks that is modular and scalable, connectable to at least one secure network connected to a plurality of network-accessible physical devices and a non-secure public network accessible via a UI module that is executable in a web browser, and comprising at least one SCRA module configured to control access to a secure network with multiple sets of network-accessible physical devices or plants, all of which are network-accessible; which may also replace an SCRA module with a CPD module connected to a secure network with access to convergent physical devices that constitute a plant or assembly; and configured to request publication to a CPS module configured to make publication requests made by the CPD module(s) visible from the non-secure public network.
