Simplify and make your operations ready for the future with a rock-solid networking and security foundation that's built on easy-to-deploy, high-performing, and secure Catalyst IE3400 Rugged Series industrial switches.
Deliver continuous operations
Keep your network performing at its peak, with all-gigabit fiber ports, Power over Ethernet (PoE)-enabled copper ports, advanced resiliency and industrial protocols, and industry certifications.
Optimize operations with IT best practices
Simplify operations with enterprise-grade networking features of the Cisco IOS XE operating system and network management with Cisco Catalyst Center.
Unify security with networking
Eliminate point products and simplify the network architecture by embedding visibility and security as software features. Get details on connected assets with Cisco Cyber Vision. Limit the spread of malware with segmentation based on the Cisco TrustSec solution.
Simplify and secure remote access
Set up zero-trust network access (ZTNA) with the hosted Cisco Secure Equipment Access gateway, so that your operations team, contractors, and vendors can troubleshoot and maintain OT assets, while you retain full control.

E80 Group ensures safe and efficient operations of their AGVs
"By leveraging the hosted and built-in defense-in-depth security features of Cisco Industrial Ethernet switches, we gain the visibility, segmentation, and device authentication necessary to detect and contain malware before it can compromise the security and safety of our deployments."
Velta builds industrial networks that are secure by design
"Gaining visibility into industrial assets is key to securing operations. The combination of [Cisco] Cyber Vision and Cisco industrial networking makes it simple to gain visibility at scale. It's the foundation for a robust OT network and a comprehensive approach to IoT security."
Unilin Group makes its manufacturing operations more secure
"When we showed operations that the Cisco network could give them visibility into what's happening in their manufacturing plant so they could solve production issues, they were ready to replace their existing network equipment. And this helped us improve security at the same time."
"We use advanced sensors on buses, ferries, and light rail to provide instant feedback on the comfort of customer journeys and improve real-time customer information. Buses fitted with this technology can also monitor asset and road conditions and provide us with real-time information on vehicles."
Joost de Kock, Deputy Secretary Customer Strategy and Technology
"We use IE3400s in our agricultural environment in California heat. It runs no matter how hot it gets, and it has operated at times where it was exceeding its operational limits. It provides all the PoE we need and controls access to ensure that guest traffic does not interact with our enterprise traffic."
TrustRadius verified reviewer, Americas, June 2023
"With Cyber Vision [running on Cisco Industrial Ethernet switches], we now have the visibility into our mission-critical OT networks as a first step to mitigate vulnerabilities and improve our security posture. Cyber Vision found more than 20 instances of malware in our substations and identified features and protocols that don't need to be active."
Emerson Cardoso, Chief Information Security Officer
Cisco industrial IoT brings manufacturing flexibility to Audi
"To increase security, decrease support requirements, and improve flexibility, Audi is developing its Edge Cloud for Production (EC4P) platform. EC4P virtualizes production assets and relies on software-defined networking by Cisco IoT and enterprise solutions that provide a scalable, resilient, secure, and deterministic network."
ARC analyzes the rise in industrial networking investments
"Industrial networks are vital strategic components for addressing today's macroeconomic, competitive, and regulatory challenges. A converged approach that incorporates IT, OT, and security requirements for centralized management and visibility is necessary to ensure secure, resilient communications from the production environment throughout the enterprise."
