Zero Trust Networking for Smart Manufacturing
Complete the form to be emailed the solution brief →
Excerpt from the Introduction
Manufacturers are constantly looking to upgrade their factories; infrastructure improvements and automation can bring down costs, improve yields, and help the manufacturer beat the competition. Most of the time, upgrading involves plugging new and intelligent computing or even cloud-based services into existing factory networks. However, many factories were designed with shared flat networks for legacy reasons, which provides an ideal platform for cybersecurity attack proliferation. With costs of idling a production line potentially exceeding $1 million per hour, manufacturers need effective ways to segment and protect this converged IT/OT environment.
Excerpt from the Summary
Zentera’s CoIP Platform allows enterprises to build an overlay network to meet the Zero Trust Security model without network redesign. This overlay ZTN is a proxy-based Layer 5 session network, built on top of the underlay L3 IP network. All core components of CoIP Platform are implemented as servers on the existing IP network, connected by “web proxy”-style SSL tunnels, enabling Zero Trust Security to be added to existing networks without changing the underlying IP network.
All applications inside a ZTN are cloaked and invisible to other applications running on the same network, with centrally-defined communication and security policies.
