DataHub | Secure OT to IT (cogentdatahub.com)
Using a DMZ is the most often recommended way to secure your plant network when you need remote access to your data.
Whether that data is going to the IT department, central office, or the cloud, you don’t want to expose the OT network.
DataHub software and services make the connection through DMZs, keeping all inbound firewall ports closed, supporting forward proxies, and requiring no VPNs.
