Converged Industrial Edge
A purpose-engineered, zero-trust network architecture.
Improve the information exchange between IT and operational technology (OT) network devices with the Converged Industrial Edge (CIE).
Improved Circuit Provisioning
Previously, to add communications from one device to another meant traversing multiple networks, which meant involving multiple system owners from OT and IT teams. They all had to coordinate to provision the circuit and configure their respective devices along the way. This process could take months to complete and it was prone to misconfigurations, fraught with engineering complexity, vulnerable to cyber attacks, and lacked system awareness.
With CIE, the WAN and LAN devices are incorporated into one deny-by-default, programmable forwarding fabric. Now, the task of provisioning that same circuit is reduced to one operator who is essentially only working with one network. The engineer enters a work order, and because the controllers in the automation plane have total visibility of the devices throughout the network, they are able to provision and test an end-to-end circuit in minutes.
Deny-by-Default Cybersecurity
A deny-by-default forwarding fabric makes up the foundation of CIE. The deny-by-default approach guarantees that only authorized messages traverse the network and eliminates many of the inherent vulnerabilities present in other network fabrics. Unauthorized packets that access the network are denied by default and immediately dropped or sent to an intrusion detection system.
SEL and CIE
SEL provides the LAN and information inventory management of the OT edge devices in the CIE architecture.
Proven Reliability and Lifetime Support
SEL products are designed and manufactured for the world’s most challenging environments, exceeding all industry standards for temperature, shock, and electric stress. An optional conformal coating for circuit boards adds an extra level of protection against contaminants in extreme environments.
Our manufacturing processes are certified to ISO 9001 Quality Management System requirements.
SEL devices are designed for a working life of at least 20 years. Every SEL-manufactured device comes with a 10-year warranty—the best in the industry. If it fails under warranty, we’ll repair or replace it for free.
Lifetime Product Support
Every device we manufacture comes with free lifetime technical support. No matter how often you need to call or how long your SEL products have been in service, you’ll reach an SEL expert who can provide the service and support you need.
It’s been this way at SEL for 35 years and counting—a major reason why we’re North America’s most trusted provider of protective relays and ranked #1 by international utilities in price, service, and support.
Cybersecurity Bulletins and Updates
We provide cybersecurity bulletins and updates for the full lifetime of every product we manufacture. SEL end-user customers can sign up to receive emailed notifications of security service bulletins affecting SEL products to help them keep their systems secure.
